bandura's social cognitive theory
attention, memory, imitation, motivation ex. want to teach you to draw a star. in order to learn it, need a long enough attention span, the memory to remember it, and be able to imitate it. question is, are you motivated enough to do it? if you do action

a neutral type of stress. happens when you are exposed to something stressful, but it doesn't actively or directly affect you. for example, news about a natural disaster on the other side of the world may be very stressful but your body doesn't perceive that stress as good or bad for you so ur not affected
molecular genetics
a new field of science that looks at the molecular structure and function of genes. as we study gene and environments interaction we are getting to understand specific gene that is regulating our behaviour. we are looking at specific parts of DNA

social support
one of best mechanisms of stress. allows us to confide the painful/difficult feelings and allows us to understand we are not alone in stress, which helps in our perceived control and optimism -socially supported communities are identified as having better eating/exercise/sleeping patterns. marriage domesticated animals, close friendships have been shown to decrease stress.
decay

Theory of Mental Abilities (LL Thurnstone)
Summary 7 factors of intelligence: word fluency, verbal comprehension, spatial reasoning, perceptual speed, numerical ability, inductive reasoning, memory strength/evidence breakdown seems intuitive ex. possible to have high inductive skills without high verbal comprehension problems how can scores vary together statistically (suggests underlying intelligence factor?) limited in what it considers to be intelligence
Theory of General Intelligence (charles spearman)
Summary: used factor analysis to identify cluster of related abilities 1 general rule g factor - can predict our intelligence in multiple academic areas strength/evidence: theory supported by research those who score high in one area also score highly in other areas. ex. scoring high in verbal intelligence correlated to high special reasoning problems: controversial can one factor explain all of the diverse human abilities? limited in what it considers to be intelligence
dopamine
VTA and substantiated nivea next to VTA in the brainstem (overlapping) sends axons release dopamine to a few nuclei deep in the cerebral hemisphere (all parts of the basal ganglia). these brainstem (midbrain neuron collection that is projecting dopamine is called the substantial nigra). it is actually projecting dopamine to another part of the basal ganglia called the striatum. if this can't happen - this is whats called parkinson's disease - dopaminergic neurons also in the hypothalamus that send dopamine to pituitary gland to control release of one of the hormones in the pituitary gland. this is all in the CNS in the brain and the spinal cord

carl rogers
a humanistic theorist who says qualities maslow described are nurtured early in life, self actualization is a constant growth process nurtured in a growth promoting climate. in order for this climate to help someone reach self actualization, 2 conditions need to be met -- growth is nurtured by when individual its genuine. one has to be open and revealing about themselves without fear of being wrong second is growth is nurtured through acceptance - unconditional positive regard from others. this allows us to live up to our ideal selves. allows us to be open and learn without fear of others looking at us differently if we do something wrong. ex parent might yell at child but still love their child genuine relationship with others and acceptance is what allows us to live up to our real self
mass hysteria

negative symptoms of schizophrenia
blunted emotions, loss of employment "emotional abnormalities" refer to the absence of normal behaviours found in healthy individuals. common negative symptoms of schizophrenia include: lack of emotional expression - inexpensive face, including a flat voice, lack of eye contact, and blank or restricted facial expressions. -- affective flattening is the reduction in the range and intensity of emotional expression, including facial expression, voice tone, eye contact (person seems to stare, doesn't maintain eye contact in a normal process,) and is not able to interpret body language nor use appropriate body language lack of interest or enthusiasm- problems with motivation; lack of self care avolition is the reduction, difficulty, or inability to initiate and persist in goal-directed behaviour; it is often mistaken for apparent disinterest (examples of avolition include: no longer interested in going out and meeting with friends, no longer interested in activities that the person used to show enthusiasm for, no longer interested in much of anything, sitting in the house for many hours a day doing nothing seeming lack of interest in the world -- apparent unawareness of the environment; social withdrawal speech difficulties and abnormalities - inability to carry a conversation, short and sometimes disconnected replies to questions; speaking in monotone - alogia, or poverty of speech, is the lessening of speech fluency and productivity, though to reflect slowing or blocked thoughts, and often manifested as short, empty replies to questions

(Avoidance) social withdrawal, excessive autonomy
copes through social isolation, disconnection, and withdrawal. may demonstrate an exaggerated focus on independence and self reliance, rather than involvement with others. sometimes retreats through private activities such as excessive tv watching, reading, recreational computing, or solitary work
coping
coping is expanding conscious effort to solve personal and interpersonal problems, and seeking to master, minimize or tolerate stress r conflict. the effectiveness of the coping efforts depends on the type of stress and/or conflict, the particular individual, and the circumstances. psychological coping mechanisms are commonly termed coping strategies or coping skills. subconscious or non conscious strategies (eg, defence mechanisms) are generally excluded. the term coping generally refers to adaptive or constructive coping strategies, ie the strategies reduce stress levels. however, some coping strategies can be considered maladaptive, ie stress levels increase. maladaptive coping can thus be described, in effect, as non-coping. ie, the coping response follows the stressor. this contrasts with proactive coping, in which a coping response aims to head off a future stressor - coping responses are partly controlled by personality (habitual traits) but also partly by the social environment, particularly the nature of the stressful environment
self
core circle - media, society, family interactions can be internalized by an individual and can lead to avoidance, denial of condition, suffering of mental health conditions, and no longer participating in society. useful interventions include educating, access to support groups/resources
neurulation

we can let problem incubate
insight comes after some time
basal forebrain
is a collection of structures located to the front of and below the striatum. it includes the nucleus accumbent, nucleus basalts, and medial septal nuclei. these structures are important in the production of acetylcholine, which is then distributed widely throughout the brain. the basal forebrain is considered to be the major cholinergic output of the CNS
escape
is closely related to avoidance. this technique is often demonstrated by people who experience panic attacks or have phobias. these people want to flee the situation at the first sign of anxiety
social class
status (social status) is relative (to have higher status you need a lower status). social class often sets stage for prejudice (people on top maintain differences between themselves and lower class - the just world phenomenon - good things happen to good people and bad things happen to bad people, contributes to prejudice)

upsurge in prejudice/discrimination when people are deprived of something they feel entitled to -relative depreciation is the discrepancy of what they are entitled to and what they get - extent and how quickly this happens can lead to collective unrest- an upsurge in prejudice and discrimination -linked to frustration aggression hypothesis
radio frequency lesions
used to destroy tissue on surface of brain and deep inside brain. wire is inserted into brain to determine the area. then pass high frequency current which heats up and destroys everything in the area (cell bodies and axons). you can't tell if this area was responsible for the behavioural that is not responding, or just has an axon passing through
barbiturates
used to induce sleep or reduce anxiety (calm them down) depress CNS anesthesia or anticonvulsant (drugs that reduce seizures) not often prescribed due to negative side effects such as reduced memory, judgement, and concentration, with alcohol can lead to death (most drugs with alcohol are bad) barbital

pre-conventional
(pre-adolescent) 1. obedience vs punishment - reasoning is based on physical consequences of actions, so obeying the rules isa means to avoid punishment. 2. individualism and exchange or self interest - recognize not just one right view by authorities, different individuals have different viewpoints. doing what is right for personal gain
Stage 1 (Erickson)
0-1 years, crisis is trust vs mistrust. if an infants physical and emotional needs are not met, as an adult he or she may mistrust everyone virtue is hope and failing to acquire of virtue can lead to suspicion/fear/mistrust
4 factors to determine strong/weak self efficacy
1) mastery of experience - strengthens self efficacy 2) social modelling - seeing people similar to ourselves complete the same task increases self efficacy 3) social persuasion - when someone says something positive to you, helps overcome self doubt 4) psychological responses - learning how to minimize stress and control/elevate mood in difficult/challenging situations can improve self efficacy
somatosensory information travels in different pathways. in general, 2 big categories:
1) position sense, vibration sense, and fine touch 2) pain, temperature, gross (less precise) touch deliver info to spinal cord
development to higher mental functions from elementary mental functions (social interactions)
1) requires cooperative and collaborative dialogue from a MKO (more knowledgable other) - a person with a better understanding than the learner. the interaction with the learner + MKO -> learning + higher MF 2) zone of proximal development - part where most sensitive instruction/guidance should be given ex between ability of not being able to do something and being able to do something. ZPD is the link between the zone of can't do and can do. allows learner to use their skills they already have and expand learning to things they can't do 3) language - the mean means by which adults transmit info to children, and a powerful tool of intellectual adaptation. ex private internal speech, when people speak out loud to themselves - happens most in children. way for children to plan activities/strategies, and aids their development. language is an accelerator to thinking and understanding
stage 2 (erickson)
1-3 years, autonomy vs shame/doubt. around 18 months to 3 years. children develop independence by walking away from mother, what they eat, etc. critical that parents allow children to do that. virtue is achieved is will (independence) negative outcomes: if child is overly criticized/controlled, feel inadequate and lack self esteem, and have shame/doubt in abilities
anal stage
1-3. centred around anus. ex toilet training. leads to developing control/independency, encouraging child to feel positive outcomes and helps child feel capable and productive. serve as basis for competent, productive, creative adults. - if fixation occurs, have problems with orderliness and messiness
distinct stages of stress - general adaptation syndrome (GAS) 3 phases by Hans Selye
1. alarm phase - stress reaction kicks in, heart races, resources mobilized - "ready for fight or flight" 2. resistance - fleeing, huddling, temperature elevated, BP high, breathing rate high, body bathed in cortisol 3. exhaustion - if resistance isn't followed by recovery, our body's stress resources are depleted, our tissues become damaged and our dampened immunity can make us susceptible to illness. negative impact of long term stress.
parathyroid

phallic stage
3-6, children discover difference between males and females. oedipus complex and electra complex at this stage. oedipus also develops - boys view fathers as rivals for mothers affection. describes feeling of wanting to possess mother and replace father. electra complex is the equivalent for young girls to their fathers. resoled through process of identification, where child starts to understand and develop similar characteristics as same sex parent. - if fixation occurs, cause homosexuality/exhibitionism
stage 3 (erickson)
3-6, initiate vs guilt. children feel more secure in their ability to lead others and play, so ask questions - virtue they reach is a sense of purpose in what they do and choices/decisions they make negative outcome: if tendency to ask questions is controlled, develop guilt - as if they're annoying other people and act more as a follower. inhibits their creativity, and outcome is inadequacy. some guilt is necessary so child can have self control
conventional
3. societal norms/acceptance - good boy and good girl - authority is internalized, but not questioned, and reasoning is based on group person belongs. individual is good in order to be seen as good by others, emphasis on conformity. "to gain acceptance and to avoid disapproval" 4. law and order/law abidance - maintaining social order, child is aware of wider roles of society and obeying laws "to follow rules"
in each taste bud are ____ receptor cells that can detect each taste. each taste can be detected anywhere on the tongue. each taste bud has cells specialized for each of the 5 tastes
5 receptor cells
post conventional
5. social contract - individual becomes aware that even though rules and laws exist for greater good, there are times this law works against interest of particular people. 6. universal ethical principle - people develop own set of moral guidelines, which may or may not fit the law, and principles apply to everyone. people who uphold and believe in these have to be prepared to act towards these even if they have to obey consequences/disapproval/imprisonment. very few people who reach this stage
by week 24

there are __-__ million cones
6-7
stage 4 (erickson)
6012 years, where teachers take an important role in a childs life, and child works towards competence. crisis is industry vs inferiority virtue: child will gain greater significance and greater self esteem, and try to win approval from others. competence. will feel industrious. negative outcome: but if initiative is restricted child feels inferior (don't have competence). some failure is necessary/good though, so child has modesty
stage 8 (erickson)
65+, slowing in productivity. crisis is integrity vs despair. stage where people contemplate on lives, reminisce. may feel guilty about past or unaccompanied, dissatisfied. virtue is wisdom - look back on life with sense of closure/completeness and accept death without fear but if we feel unproductive leads to despair/dissatisfaction upon death

PDE takes cGMP and converts it to ____
GMP (so when light hits, lower concentration of cGMP and increases concentration of GMP)
sweet, umami and bitter cells rely on _____ receptors
GPCR
ANS divides into SNS and PNS
SNS starts middle of spinal cord -> short axon synapses with short ganglia close to spine -> second neuron goes to the target cell (smooth, cardiac, gland cells) PNS -> starts at the brain stem or bottom of spinal cord -> 1st neuron sends long axon -> synapse with ganglion of second neuron -> sends short axon to target cell general - both have 2 chains of axons. SNS is short and then long. PNS is long and then short

a heuristic where we analyze the main problem and break it down into smaller problems. we then attack the problem that has the most different between current state and goal state. solve biggest -> smallest problem. current state -> goal state. ex, planning a trip to a new country, biggest problem would be to get to the new country, so you book a plane ticket to a new country
delusions of reference
a neutral environmental event is believed to have a special and personal meaning. for example, a person with schizophrenia might believe a billboard or person on TV is sending a message meant specifically for them.
trait theory
a personality trait is a stable predisposition towards a certain behaviour. straightforward way to describe personality - puts it in patterns of behaviour. description of traits instead of explaining them
positive priming
a positive prime speeds up processing. caused by simply experiencing the stimulus. positive priming is thought to be caused by spreading activation. this means that the first stimulus activates parts of a particular representation or association in memory just before carrying out an action or task. the representation is already partially activated when the second stimulus is encountered, so less additional activation is needed for one to become consciously aware of it
lewis merman
a psychologist f stanford university furthered/modified binet;s intelligence test and also incorporated teenagers and adults. this was named the stanford -binet intelligence test. merman noted that binet's test was not predictive of US children
abraham maslow's hierarchy of needs
a pyramid. we have needs that must be fulfilled from bottom to top. these needs must be fulfilled in a specific bottom -> top order basic needs are most fundamental and at bottom there are 5 needs acronyms: Please Stop Liking Stupid Shit physiological: food, water, breathing, sleep. essential to survive (basic need) -safety needs are associated with stability, security, protection, and freedom from threats love: need to belong, acceptance from friends/family intimacy, love. social needs/belonging self esteem: feel confident and sense of achievement, recognition, competence of skill, respect self actualization: one reaching their maximal potential, achieving the most one can be. they were moral to their own principles and mastered the other needs. differs from person to person. maximum potential - one can want to be ideal parent, or ideal athlete or ideal artist

Gate control theory of olfaction
a theory of the processes of nociception. the gate control theory of pain asserts that non-painful input closes the "gates" to painful input, which prevents pain sensation from travelling to the central nervous system. Therefore, stimulation by non-noxious input is able to suppress pain. "fast blocks slow" Ronald Melzack and Patrick Wall
vigilance

abnormalities in neural pathways using certain NTs (depression)
abnormalities in pathways cause abnormal increase or decrease activity in the brain. collection of neurons have cell bodies in brain stem while axons project into frontal lobe/limbic system. one structure starts in the raphe nuclei of the brainstem responsible for serotonin release. another pathway starts in the locus coeruleus, which sends long axons to cerebrum and releases norepinephrine. also the VTA sends long axons to different areas of cerebrum, supplies dopamine medications that affect serotonin, NE, and dopamine often improve symptoms.
cognitive symptoms of schizophrenia
abnormalities of attention, organization, planning abilities, disorganized thinking, slow thinking, difficulty understanding, poor concentration, poor memory, difficulty expressing thought, difficulty integrating thoughts, feelings and behaviour
rational techniques
accept reality prevent or correct injustice - with cavities, sign a petition or changes to legal system
3 categories of 12 steps are:
acceptance - acknowledge addiction is a chronic progressive disease that you can't control surrender - give yourself over to higher power and accept help offered through that power and group active involvement in meetings/activities - can include helping other addicts
practice
activities well practiced become automatic processes, or things that occur without need for attention. whether task is automatic vs. controlled is determined by the amount of practice. a controlled task is harder, and would struggle to complete if attention is divided. automatic task occurs with greater experience.
nicotine
acts on acetylcholine
adoption studies
adopted child is compared to biological family and their adopted family. biological parents have shared gene to an adopted child but the parents (or other twin who grew up with biological parents) will have markedly different environments - if environmental factor plays a big role, the adoptive child would be similar to adoptive parent and dissimilar to parents - if genetics is predominate player, the adoptive child would be similar to biological parent and not the adoptive parent

affective behavioural cognitive
stage 5 (erickson)
age 12-20, adolescence. transition from childhood to adulthood, so one of most important criss. want to start feeling they belong in society - identity vs role confusion. in this stage, the child has to learn rules he needs to occupy as an adult, so may reexamine identity to figure out who they are. body image plays a big role. virtue is fidelity, seeing oneself as unique failure: role confusion. can cause rebellion/unhappiness
amygdala
aka aggression centre. if you stimulate amygdala, produces anger/violence and fear/anxiety - if you destroy, get mellowing effect. clever-bucy syndrome - bilateral destruction (destruction of both) amygdala can result in hyperorality (put things in most a lot), hyper sexuality, and distinguished behaviour. these are all drunken behaviours. damaged amygdala -> patients given bentos (act like alc.) those who have anxiety, whom are given bentos, and you see these behaviours
hawthorne effect
aka observer effect type of reactivity in which individuals modify or improve an aspect of their behaviour in response to their awareness of being observed - hawthorne effect occurs when an individual participant changes his or her behaviour, specifically due to the awareness of being observed `
self concept
aka self identity is how someone thinks about/perceives/evaluates themselves, aka self awareness
counterconditioning
aka stimulus substitution is a form of respondent conditioning that involves the conditioning of an unwanted behaviour or response to a stimulus into a wanted behaviour or response by the association of positive actions with the stimulus
step 1: categorize
all humans categorize ourselves and others without really realized it, part of human nature. categorize in order to understand objects/identify them. ex categorize to groups (which we belong to and those different) like race, job
random mating
all individuals within a species are equally likely to mate with each other. mating not influenced by environment/heredity or any behavioural/social limitation. ensures a large amount of genetic diversity
broadbent's early selection theory
all information in environment goes into sensory register (which briefly registers/stores EVERYTHING/all sensory information you receive such as words, clicks, sirens, etc) then the info gets transferred to selective filter right away which identifies what you are supposed to be attending to via basic physical characteristics and filters out stuff un unattended ear based on things you don't need to understand to identify (based on voice, pitch, speed, accents, etc) and finally information moves to perceptual processes identifies friend's voice and assigns meaning to words. then you engage in other cognitive processes such as deciding how to respond. sensory regulator -> selective filter -> perceptual process -> conscious
procedural memories
all memories formed by conditioning are implicit memories implicit memories are formed unconsciously all habits are procedural memories, a type of implicit memory memories that inform unconscious motor skills are procedural memories, a type of implicit memory procedural memory is long term memory for actions or habits such as how to kick a ball or washing hands before eating. procedural memory is a type of implicit memory. habit learning occurs in a specific type of implicit memory habits/implicit memory is stored in the basal ganglia
gordon allport
all of us have different traits. came up with list of 4500 different descriptive words for traits. from those he was able to come up with 3 basic categories of traits: cardinal traits, central traits, and secondary traits
directed attention
allows attention to be focused sustainably on a single task, in this case a single orientation of the Necker cube
transfusing is a molecule made of 3 different parts:
alpha, beta and gamma that is attached to rhodopsin typically
marijuna
also a mild hallucinogen. main active chemical is THC, which heightens sensitivity to sounds, tastes, smells, like alcohol, reduces inhibition, impairs motor and coordination skills, perceptual skills disrupt memory formation, and short term recall stays in body up to a week's so regular users need less of the drug rather than more to receive the same high
role exit
also called social role. ex when an individual stops engaging in a role previously central to their identity and the process of establishing a new identity
biopsychosocial
also considers abnormalities and might be useful for cause or classification of mental disorder but also includes psychological and cultural/social factors that might be useful for cause or classification of mental disorder
authoritative parenting
also strict, consistent and loving but more pragmatic and issue-oriented and listen to children's arguments. balance responsibility with rights of child. discipline
attitude to behaviour process model (attitude - behaviour)
an event triggers our attitude (something that will influence our perception of an object) then attitude + some outside knowledge (what regarded as appropriate behaviour) together determines behaviour
effort justification
an idea and paradigm in social psychology stemming form festinger's theory of cognitive dissonance. it is people's tendency to attribute a greater value (greater than the objective value) to an outcome they have to put effort into acquiring or achieving.
negative priming
an implicit memory effect in which prior exposure to a stimulus unfavourably influences the response to the same stimulus. caused by experiencing the stimulus, and then ignoring it. negative prime lowers the speed to slower than un primed levels
IQ measures what type of intelligence
analytical
3 types of intelligences
analytical intelligence - academic abilities - to solve well defined problems creative intelligence - ability to adapt to new situations and generate novel ideas and adapt practical intelligence - solve ill defined problems, such as how to get a bookcase up a curvy staircase - proposed by robert sternburg
one of the major emotional responses of stress is depression
anhedonia - inability to experience pleasure, so perceive more stressors
solitary forcing
animal looks for food by itself.
group foraging
animals look for food in groups. hunting based on both your behaviour and those around you. can leas to competition whiten a group if food is scarce. benefit of this strategy is that animal's can take down larger/more aggressive prey and everyone can benefit
proactive coping
anticipating a problem anticipation is when one reduces the stress of some difficult challenge by anticipating what it will be like and preparing for how one is going to cope with it
cluster b has 4 personality disorders
antisocial: little or no regard for others. commit crimes and show no remorse. inconsiderate of others borderline: unstable relationships, emotions are unstable, variable self image and compulsive. people at the borderline are at the brink of emotional/relationship issue. ex displays characteristics of a stereotypical teenager histrionic: are very attention seeking. display emotions outwardly, wear bright clothes narcissistic: huge egos, need for admiration and praise, grandiose, ex dr house, hitler,
aggression
any physical/verbal behaviour intended to harm or destroy.
passive aggressiveness, rebellion
appears overtly compliant while punishing others or rebelling covertly through procrastination, pouting, backstabbing, lateness, complaining, rebellion, non-performance, etc
posterior chamber
area behind the iris to the back of lends, also filled with aqueous humour
norepinephrine
area in pons called the locus coeruleus that releases it to cerebral cortex. Also ANS, but less so than Act.
abnormal activity in brain of depressed people
areas with abnormal activity involve the frontal lobe and limbic structures. decreased activity in frontal lobe and increased activity in limbic structures. show a role in regulation of emotions and response to stress. ex stress hormones like cortisol are controlled by hypothalamus, which communicates with limbic system and frontal lobe. hormones affect the brain themselves too - communication of frontal lobe, limbic system, and hypothalamus may play a role why there are abnormal hormones in the body - stress hormones affect most tissues of the body and the brain (including hypothalamus, limbic system, and frontal lobe) - unclear which abnormalities of stress hormone are caused and which are effects of the disease
pleasure principle
as a young child (or if you are immature) you want to immediately feel pleasure to avoid suffering. not willing to compromise
heritability increases in following:
as environments become more controlled, differences in behavioural traits are tied to heritability. secondly, more genetic variation leads to greater variability ex. fraternal quadruplets with way more different phenotypes. the differences are tied to the genes/heritability as well if environments are kept constant - in heritability we are talking about the relative contributions of genes to behaviours or traits heritability is dependent on population that is studied. heritability is specific to the population studied and would likely be different in different environments
the vibrational theory of olfaction
asserts that the vibrational frequency of a molecule gives the molecule its specific odour profile
primary appraisal
assessing stress in present situation. 3 categories of response to this primary appraisal - irrelevant, benign/positive, or stressful/negative. if primary appraisal is negative (stressful), move forward with secondary appraisal
beta (12-30Hz)
associated with awake/concentraion. if you are alert for too long, beta levels get high and you experience increased stress, anxiety, restlessness - constant awakened alertness
recognition
best out of the 3 tests/easiest to recall. present 2 words, and say which one you heard. retrieval of correct word is highly likely.
pavlov
associated with classical conditioning. ex, pavlov dog experiment. places a neutral stimulus with an unconditioned stimulus to trigger an involuntary response. ex ringing a bell in presence of food causes dog to start salivating - people have consistent behaviour patterns because we have specific response tendencies, but these can change, and thats why our personality develops over our entire lifespan. constantly evolving and changing
extrinsic motivation
associated with rewards or obligated behaviour. extrinsic motivation is motivation to do something based on an external reward (like money or fame)
semantics
association of meaning with a word. semantics are the broad meanings of each word, phrase, sentence, or text. N400 response, bigger with bigger violation
suspensory ligaments
attached to a ciliary muscle. these 2 things together form the ciliary bond, what secretes the aqueous humour
vygotsky sociocultural development babies have 4 elementary mental functions:
attention sensation perception memory
divided attention
attention is a limited resource. can't split it very well. Doing 2X at once you end up switching between tasks rather than doing them simultaneously. divided attention occurs when an individual must perform 2 tasks which require attention simultaneously
prejudice
attitudes that prejudice a group, usually negative and not based on facts. make same assumptions about everyone in a group without considering their differences.
stereotyping
attributing a certain thought/cognition to a group of individuals, and overgeneralizing
anthropomorphism
attributing human characteristics to non human animal's
distinctiveness of a situation =
attribution to external factors
3 types of hormones effects
autocrine - effects the cell that makes it paracrine - regional effect endocrine signals - response that is far away
cluster c has 3 personality disorders
avoidant: inhibited, feel inadequate, and try to avoid putting themselves in a situation where they can be criticized dependentL submissive and clingy ex. those who stay in physically abusive relationships obsessive-compulsive personality disorders: very focused on life being ordered and things being perfect and for them being in control to an extent where it annoys other people. it is a personality! on the other hand, in OCD the focus is on order, things in control, having to wash hands
addictive self soothing
avoids through addictions involving the body, such as alcohol, drugs, overeating, addictive masturbation, etc
genital stage
back on libido, because individual develops strong sexual interests. before this stage, focus on individual needs. now, focus on needs of others. no adult fixation - person is mentally healthy. goal: establish balance between various life areas (well balanced, warm, caring)
Why injury to one side of brain often results in damage to other side ->
because all the somatosensory pathways cross to the other side
continuous reinforcement
becomes less reinforcing so there is a need for ulterior reinforcement. continuous reinforcement occurs on a 1:1 ratio - this means that for each behaviour, there is a reward. discovered by bf skinner
stage 1: pre processing stage due to target characteristics
before we can consider information or be persuaded by it, the information is first filtered by interest, motivation, or importance central processing: if listener interest, motivation, importance are high. people will only choose this route when they are interested in the topic peripheral processing: if listen interest, motivation, importance are low we process via the peripheral route. chosen when listener doesn't care about topic we filter info before we can even process it
bottom up processing
begins with stimulus. Influences what we perceive (our perception) - no preconceived cognitive constructs of the stimulus (never seen it before) - data driven. and the stimulus directs cognitive awareness of what you're looking at (object) - inductive reasoning. always correct
endocrine system related to behaviour
behaviour coordinated response to environment hormones effect how we respond to attitude/personality cognitive betrayal therapy: control what your body is doing physiologically with your mind. when you are afraid for example, epinephrine causes increased heart rate etc. (fight or flight response). when you are no longer scared, become calmer and hormones then get reduced)
prototype Willingness Model (PWM)
behaviour is a function of 6 things, the combination of which influence our behaviour. our behaviour is a function of... past behaviour attitudes - explained in attitude to behaviour processing model; attitude -> behaviour subjective norms - what others think about our behaviour our intentions - our behaviour intentions our willingness to engage in a specific type of behaviour models/prototyping - a lot of our behaviour is carried out from prototyping/modelling
partial reinforcement schedule
behaviour is reinforced only some of the time. more resistant to extinction than continuous reinforcement. behaviour is shaped through a process of successive reinforcement of approximations of target behaviour
psychological factors - in depression, the following occur
behavioural theory - "learned helplessness" begin to feel powerless if they have no control over the environment they are in repeatedly. uncontrollable exposure to an aversive stimulus "independent to intensity of punishment" cognitive theory - cognitive distortions - getting trapped in negative thought pattern, when you continue to think about negative thoughts cognitive theory - attribution. these form a pessimistic/negative attributional style which makes people vulnerable to depression - individuals with depression link negative experiences to internal causes. they think negative experiences will continue to occur in the future. they also think negative experiences are global. are pessimistic attribution style individuals more likely to have depression or is it the other way around. not always clear
taboos
behaviours completely forbidden/wrong in any circumstances, and violation results in consequences far more extreme than a more. often punishable by law (with serious legal consequences) and a result in severe disgust by members of community. considered very immoral behaviour. ex incest (sexual relationships between family members) and cannibalism (eating human flesh)
optimism bias
belief bad things happen to others, but not to us
self efficacy
belief in ones abilities to succeed in a situation/to organize and execute the courses of action required in a particular situation. developed by bandora due to his dissatisfaction with idea of self esteem,
delusions of grandeur
belief that one is a famous or important figure, such as jesus christ or napoleon. alternatively, delusions of grandeur may involve the belief that one has unusual powers that no one else has (eg, that ability to fly)
lens
bends the light so it goes to back of eyeball -- focuses light specifically on the fovea of the retina. adjust how much it bends the light by changing its shape, using the suspensory ligaments
amphetamines
both block dopamine reuptake and stimulate presynaptic dopamine release.
global aphasia
both broca's aphasia and wernicke's aphasia are damaged. combination of impaired comprehension and production of speech
CNS
brain and spinal cord brain includes cerebrum, cerebral hemisphere, brainstem (midbrain, pons, and medulla) and cerebellum forebrain, midbrain, hindbrain. forebrain becomes cerebrum, midbrain becomes midbrain, and hindbrain becomes pons/medulla/cerebellum
abnormalities in neuroplasticity (Depression)
brain changes in response to experience. but unclear if neuroplasticity abnormalities is a cause or effect. strength of information/efficiency of flow changes or connections change. aspects of neuroplasticity appear to be normal in animals of major depressive disorder. may include genetics (predisposition can be inherited, increase risk of developing a response to negative or stressful event particularly early in life), but psychosocial factors can also be linked to major depressive disorder such as childhood abuse, stressful events or limited social support during adverse circumstances. so likely combination of biological and psychosocial factors
activation synthesis hypothesis
brain gets a lot of neural impulses in brainstem, which is sometimes interpreted by the frontal cortex brainstem = activation, and cortex = synthesis our brain is simply trying to find meaning from random brain activity. therefore dreams might not have meaning
2 modern types of studying brain
brain structure brain function
biological basis of Alzheimers
brain tissue has decreased in size significantly - shrivelled up, atrophy - its the cerebrum that often dramatically decreased in size. severity of atrophy correlates with severity of dementia starts in temporal loves, important for memory later, atrophy spreads to parietal and frontal lobes. many cognitive functions
old brain (all occur outside of our awareness)
brainstem (mostly covered by brain) and is the medulla and pons. controls heart beat/breathing and cross over point of our nerves reticular formation: from brainstem to other brain areas. it filters info and sends important info to the thalamus. sleep/wake cycle (arousal). ability to be aware. thalamus (above brainstem) relay station (eye/ear info) goes to thalamus cerebellum - coordinates voluntary movement (alcohol effects in this area)
social anomie
breakdown of social bonds between an individual and community. a situation in which society does not have the support of a firm collective consciousness. social anomie can also result in social groups disbanding, and alienation from social groups. to resolve social anomie, social norms must be strengthened and groups must redevelop sets of shared norms. can lead to uncertainty in social situations. means that there is a weakened sense of morality and criteria for behaviour
inhalation
breathing or snorting or smoking, because once you inhale goes straight to brain, insufflation inhaling drugs through the nose is highly addictive but less addictive than drugs that are injected. 10 seconds
temperament
broader than personality. its their characteristic emotional reactivity, intensity, their shyness and their sociability. temperament seems to be established before babies are exposed to environment. persistent as person ages - there is a difference between children, not all people have the same as temperament. babies/children's/people have different ways they respond to environment/parents. ex one baby can be relaxed (easy), another irritable/tense (difficult) and another can show flat affect (withdrawn). we can differentiate babies in different ways as well the withdrawn person is more likely to be withdrawn as an adult temperament is hard wired into us at birth, and persistent as we age
myers briggs personality test
carl jung 4 letters that characterize you in one of 16 personality types. there are a set of traits/behaviours based on these! ESTJ: extraversion (E), sensing (S), thinking (T) judgement (J) INFP: introversion (I) iNtuition (N) Feeling (F) Perception (P)
catatonic schizophrenia
catatonic schizophrenia is a type of (subtype) of schizophrenia that includes extremes of behaviour. at one end of the extreme the patient cannot speak, move or respond -- there is a dramatic reduction in activity where virtually all movement stops, as in a catatonic stupor
korsakoff's syndrome
caused by a lack of vitamin B1 or thiamine. caused by malnutrition, eating disorders, and especially alcoholism. these groups don't process or absorb all the nutrients they need
muscle stretch reflex
causes a muscle to contact after its stretched, as a protective response. ex, knee jerk response - involuntary response of leg kicking out. the hammer hits the tendon right below the knee cap, which hooks right onto the lower leg bone on one end, and a large group of upper muscles on the other. muscles are called muscle spindles
central sleep apnea
central (brain is part of CNS) sleep (at night), apnea (effects airflow) - looking fro apnea without obstructions. looking at 5+ appease/hour during sleep problem with the brains control system for ventilation (that control brain for breathing) cheyness-stroke breathing- crescendo then decrescendo breathing followed by stop in breathing. normal breathing pattern is inhale/exhale changes from a normal fixed pattern --believed heart failure/stroke/renal failure is the cause
both rogers + maslow
central feature of our personality is self concept - achieved when we bring genuineness and acceptance together to achieve growth-promoting climate. when theres discrepancy between conscious values and unconscious true values leads to tension, must be resolved genuine + acceptance = self concept
stage 3: change in attitude
central processing: creates a lasting attitude change peripheral processing: creates a temporary attitude change
stage 2: processing stage by message/source
central processing: focus on a deep processing of the information peripheral processing: focus on superficial characteristics (shallow processing of info) such as attractiveness of speaker, their powerpoint attractiveness, or even how many points the speaker made. how many times speaker got audience to laugh, etc
anxiety
centres the amygdala. amygdala - fears and phobias, fits in perfectly with response to stress. perceive more things as fearful - accompanies the flight aspect of sympathetic response
privately conform
change behaviours and opinions to align with group
how to improve self control (4 ways)
change environment operant conditioning classical conditioning deprivation
neural plasticity
changes in brain size/ and involves function of environmental influences
epigenetics
changes to gene expression resulting from changes other than to gene/DNA sequence. ex addition of methyl groups to the gene, which makes it more difficult for TFs to come in and activate gene. epigenetics can override our behaviour - epigenetics is the study of changes ing one expression hat result in something other than changes to a DNA sequence. one epigenetic change is methylation, which can make it more difficult for a gene to be expressed
sublimation
channeling negative to positive energy. ex violent energy, instead of expressing violence you become a boxer. transform into socially acceptable behaviours
latent learning
learned behaviour is not expressed until required
riots
characterized by large numbers of people who engage in dangerous behaviour, such as vandalism, violence, or other crimes. riots are very chaotic and cost cities millions in damages. can be result of perceived issue. cause of act can be legitimate, the group acts out in ways that are illegal/damaging to society as a whole - a riot is a violent form of crowd behaviour that results from feelings of injustice or feeling that has been ignored. riots typically result in property damage and other significant crimes - mob is a group of individuals who are emotional and violent, but target specific individuals or categories of individuals
OCD
characterized by obsessions and compulsions obsessions: unwanted repetitive thoughts compulsionsL unwanted repetitive actions these obsessions and compulsions persistently interfere with everyday life. ex continuously washing ur hands multiple times throughout the day to the point where ur skin becomes rock - for normal people, once you perform the action the worry goes away and doesn't interfere with ur life. the worry doesn't continue to occupy the brain. ex checking if door is locked, or washing ur hands shortly after touching something gross common obsessions: dirty, bad future (something terrible is about to happen), ex someone in your family is about to get sick to the point that they don't think about other things), need for symmetry (feel uncomfortable unless things around them are ordered to the point they continue thinking about it ex a book is slanted and u think about it till u fix it. if u don't something bad will happen - remember: these must invade ur everyday life and the obsessions are an extreme common compulsions: washing (intense need to wash hand, to bathe, or groom). check doors/appliances (constantly/repeatedly), movement ritual (feeling the need to repeatedly sit down/stand up, leave room and come back, tap on a desk) 2-3% of people, typically, teen and young adult
depression/major depressive disorder
characterized by prolonged feeling of helplessness and discouragement about the future. individuals with this disorder have the following: suicidal thoughts- low self esteem, low mood interests decreased: lack of interest guilt energy decreased - lethargy concentration decreased - trouble making decisions appetite disturbance - increased/decreased psychomotor changes/symptoms (agitation or retardation) sleep disturbances (increased/decreased) + weight gain or loss
optic nerves from each eye networks the electrical signal to the brain and converge from each eye at the optic _____ and then break off and dig deeper into the brain
chiasm
nativist perspective
children are born with ability to learn language. associated with noam chomsky. thought humans had a language acquisition device (LAD) that allowed them to learn language. idea that this ability exists - all languages shared universal grammar (same basic elements like sounds, verb, etc) so LAD enables child to pick up on/understand those types of words and their organization within a sentence for any language - goes along with idea of critical period (aka sensitive period)
learning (behaviourist) theory
children aren't born with anything, they only acquire language through operant conditioning. child learns to say "mama" because every time they say that, mom reinforces child. but doesn't explain how they can produce words they've never head before or unique sentences. associated with BF skinner
well defined problems
clear starting and ending point. a well defined problem has clear criteria that describe whether or not the goal has been achieved
primary groups
closest members of the group to you. close intimate long term relationships. give a dense of belonging and shared identity.
sociocultural/environment factors
co-rumination/empathy: having a friend/roomate/partner with depression can increase likelihood of individuals around you getting depression. might be due to people talking about problems and the negatives of them instead of how to solve them. you also take on the (empathize) with the emotions of those close to you. this empathy might cause depression low socio-economic status or those who lost job/struggling to keep a job have a higher risk of developing depression social isolation/child abuse inernaalization of prejudice = higher likelihood of depression
higher =
cognition (thinking), emotions (feelings) and consciousness
proprioception is ______, kinaesthesia is _______
cognitive behavioural
cognitive dissonance
cognitive dissonance is the discomfort experienced when holding 2 or more conflicting cognitions (ideas, beliefs, values, emotional reaction) these conflicting ideas lead to feelings of discomfort which we want to alleviate. these conflicting ideas can be alleviated by alterations in our beliefs/behaviours. we want to reduce the discomfort by minimizing the dissonance/inconsistencies/contradictions
3 categories of symptoms of schizophrenia:
cognitive, positive, negative symptoms
categorical self
comes once baby realizes they are separate (comes after existential self) - becoming aware that even though we're separate/distinct objects/beings, we also exist in the world with others. and each of these objects/entities has properties. ex age, gender are the first categories babies first learn, then skills and size. then as we grow older compare ourselves with others - traits, comparisons, careers (these are more developed categories)
somatosensory communication
communicate through touch and movement. movement can also convey food location (bees), pair/group bonding
classical twin study -
compare monozygotic + dizygotic each raised in same household
types of learned behaviours
complex behaviour- combination of innate and learned behaviour. relationships between genes and environment in adaptation. can be a spectrum, most behaviours fit between innate and learned - ability of insects to fly. starts as innate but through learning become more efficient in ability to fly genes/environments forms behaviour and they also contribute to the adaptive role of these behaviours covert behaviour - covert behaviour is behaviour that is not observable
# of types of conformity and obedience
compliance identification internalization
surrender
compliance, dependence: relies on others, gives in, seeks affiliation, passive, dependent, submissive, clinging, avoids conflict, people releasing
prejudice is made of 3 components
component 1: cognition (stereotype) - fundamental underlying though overgeneralized belief (cognition) component 2: affect-prejudice carries an emotional component Component 3: discrimination (tendency of prejudice to lead to behaviour) - capacity to carry out a behaviour and act on prejudice (ABC model)
strength of a signal is variable d'
d' strength hit > miss (when there is a strong signal) miss > hit (weak signal)
broca's aphasia
damage to language production centres of the brain. produce broken/halted speech. frontal lobe region damaged characterized by apraxia, a disorder of motor planning which causes problems producing speech

depth, form, motion, constancy
the labeled line theory of olfaction
describes a scenario where each receptor would respond to specific stimuli and is directly linked to the brain
demand characteristics
describes how participants change behaviour to match expectations of experimenter. conformed because thats what experimenter wanted them to do
generalized anxiety disorder (GAD)
describes person whose general state is tense and uneasy to a degree it influences their life (don't eat well or are sleep deprive for example). this anxiety must last for 6 months or more. - identifiable physical symptoms: eyelids, twitching eyelids, trembling, fidgeting population it affects: women (2/3 are women) source of anxiety: unclear can't identify the cause of their stress so they can deal with it or identify it/cause can lead to high BP and other bodily symptoms usually have also depression (not part of this disorder but can go along with it) continuous high level of anxiety
socialization
describes the process by which people learn the attitudes, behaviours, and values expected by their culture/community. socialization learning occurs through observation of/interaction with people who we are surrounded by - those close to us and everyone else - everyone has something to teach us on how we should act in our community - also shapes our self image and self concept, and charles cooley used the term "looking glass self" to describe this process
obedience
descries how we follow orders/obey authority. no cognitive component ex im just following orders
smell
desensitized receptors in your nose to molecule sensory information over time

dizygotic twins
develop from 2 separately fertilized eggs. share 50% of genes, like regular siblings both
humanistic theory
developed by carl rogers focuses on healthy personality development and humans are seen as inherently good. the most basic motive of all people is the actualizing tendency (self actualization), innate drive to maintain and enhance oneself to full potential. it also says that people have free will. person will grow towards self actualization as long as there are no obstacles
physical changes of puberty
development of primary sex characteristics (testes males and ovaries female) secondary sex characteristics (related to sexual development but not required). males - change in voice/growth of body hair, growth spurt. females - breast/hips. both genders: pubic hair/underarm hair sequence of changes are same but timing is not the same in all individuals. depends on height, weight, and individual social effects of timing of puberty males: early puberty males have both negative and positive consequences positive: stronger/taller (more athletic), popular, independent negative: increase delinquency and alcohol use females: only negatives: teasing, sexual harassment,. out of sync with friends in interests
when norm is violated, its referred to as a _____
deviance. not negative, just individuals behaving differently from what society feels is normal. deviance is relative just like norms. based on content, individuals, group and country

inside rods are optic _____, which are large membrane bound structures -- thousands of them. in membrane of each optic disc are proteins that fire APs to the brain
discs
schizophrenia
disorder of the brain but it has nothing to do with multiple personalities combination of genetics and environmental (experience in the womb, childhood experiences) cause abnormalities in the brain these abnormalities in the brain can be picked up by abnormal brain scans and NTs (high dopamine). antipsychotic medicines reduce dopamine. none of the tests actually diagnose schizophrenia and is diagnosed by a clinical interview (history, hearing from the patient/family, and observing patient) why do we observe the patient? it causes changes in the patient's behaviour? - the behavioural change can be changes in the way they think or act -- differences in the way they think: abnormal beliefs (delusions), see/hear things (hallucinations) differences in the way they act: isolate themselves socially, disorganized, flat affect (lack emotion) lots of changes that are different 1% of people have schizophrenia. equal in males and females. affects those who are 16-30 years old. males are affected at a younger age than females
aphasia
disorder that involves language. aphasia is a communication disorder that causes problems with language, like speaking, listening, reading and writing
mental disorders
disorders of the mind. mental illness, psychological pyschiatric illness. abnormalities of the mind that cause distress or disability. sometimes can shorten someone's lifespan (suicide or other negative effects)
examples of maladaptive behaviour strategies
dissociation, sensitization, safety behaviours, anxious avoidance, and escape (including self meditation)

distinguishing qualities and characteristics that compose us. our attributes. ex our temperament of our eye colour
pathological defence mechanisms
distort reality denial - person pretends something hasn't happened. most important defence mechanism
hallucinogens (psychedelics)
distorted perceptions/hallucinogens - seeing or hearing things different from how things actually are heightened sensations. based on reality but is different from whats going on in the world around. can give them energy or calm them down emotional responses - feeling of connectedness and mood swings (changing moods) exact effect can be different depending on an individuals personality or who they are.who they are with
definition of distress
distress is a negative type of stress that builds over time and is bad for your body. it happens when you perceive a situation to be threatening to you in some way, and your body becomes primed to respond to that threat
gender dysphoria
distress/disability caused by person identifying as a different gender than society represents them as. must cause distress/disability
drama/stressor related disorders
distress/disability form occurs after stressful/traumatic events. leads to mood, emotional and behavioural abnormalities - ex post traumatic stress disorder, common after wards or other traumatic experiences
anxiety disorders
distress/disability from abnormal worry/fear. some are specific to certain stimuli like phobias, while others are not specific to certain stimuli, including generalized anxiety disorder. panic disorder involves panic attacks (intense anxiety) - social anxiety disorder a false cognition leads to a fear of humiliation, embrassament, rejection, negative evaluation, or rejection by others ---- selective mutism is an anxiety disorder characterized by difficulty speaking in social situations, but the individual is developmentally normative in terms of their language and communication ability. general anxiety disorder: individuals with generalized anxiety disorder experience excessive and persistent worry or anxiety regarding many different spheres of life that cause distress, impairment, or maladaptive behaviour
sexual dysfunctions
distress/disability from abnormalities in or performance of sexual activity
dissociative disorders
distress/disability from abnormalities of identity or memory - multiple personalities, people who have lost memories for part of their lives
depressive disorders
distress/disability from abnormally negative mood. mood refers to long term emotional state. (mood is not emotion, mood is more long term and not necessarily related to events). mood is also subjective experience person has of their experience - mood (how someone feels such as sad) becomes affect (how mood is displayed to others - person crying). hopelessness, loss of enjoyment in activities. high risk of suicide
other disorders
distress/disability from any person that appears to have a mental disorder causing distress/disability but doesn't fit into other categories rare
feeding and eating disorders
distress/disability from behavioural abnormalities related to food - ex anorexia nervosa (takes in insufficient amounts of food), bulimia nervosa (binge eating then purging (induced vomiting))
disruptive, impulse control, and conduct disorders
distress/disability from behaviours that are unacceptably disruptive or impulsive for someones culture. inability to control inappropriate behaviours
paraphillic disorders
distress/disability from having sexual arousal to unusual stimuli for a person's culture. must cause distress/disability or if causes harm to another person, particularly people or a child who does not have decision making capacity for proper consent
obsessive compulsive and related disorders
distress/disability from obsessions or compulsions obsessions - thoughts that occur involuntarily, often unwelcome. occur repeatedly compulsions - are activities that one must do and are often related to an obsession ex obsession with hands being dirty, compulsion to wash them many times a day
secondary appraisal
evaluation of the individual's ability to cope with the situation. what is the individual's material preparedness to deal with stressor. appraisal of harm, threat, and challenge (how to overcome it)
somatic symptom and related disorders
distress/disability from symptoms similar to those that may occur to illness unrelated to mental disorder, but of psychological origin with or without having a general medical condition at the same time - example is someone that has abdominal pain, caused by psychological disorders such as stress without any physical signs
substance related and addictive disorders
distress/disability from the abnormal use of substances that affect mental function. include alcohol, caffeine, cannabis, hallucinogens, inhalants, opioids, sedatives, hypnotics, anxiolytics, stimulants, tobacco, others. can cause mood abnormalities, anxiety symptoms, or psychosis. also includes gambling
elimination disorders
distress/disability from urination/defecation at inappropriate times or places - ex urinary accidents
personality disorders
distress/disability related to personality. involves long term mental and behavioural features that are characteristic of a person, huge spectrum of personality types considered acceptable from a culture. personality disorders involve ones outside those accepted of societal norms. cluster A off/eccentric (weird), saluter B intense emotional/relationship problems (wild), cluster C is anxious/avoidant/obsessive (worried)
gestation
divide it into months (9 months-10) or trimesters (3 months each) or divide into weeks (10/20/30/40 weeks). weeks is best/scientifically accurate/useful
damaging effects of stress on our immune function
divided into innate vs adaptive causes inflammation - acute stress can lead to overuse of immune system. can attack our own body. good example is arthritis (joint become overly inflamed) chronic stress: stop activating immune system response and it suppresses you. doesn't make you sick, but makes you more susceptible to illness - 40% slower healing rate for puncture wounds delivered to grad students right before exam compared to same wounds inflicted during summer vacation - increased susceptibility to virus to stressful individuals. 20% increase in development of cold stress can have damaging effects
ecological validity
do the conditions of the study mimic those of the real world. if they don't , we can only make limited conclusions. a line in lab is not same as conformity in the real world
sight
does regulation or up regulation to light intensity
exogenous/external cues:
don't have to tell ourselves to look for them in order for them to capture our attention. ex, bright colours, loud noises, "pop out effect") - exogenous attention is driven by bottom up or external events, ie pop out
incentive theory focuses on positive reinforcement
done through continuous positive stimulation. a positive reinforce is given after a response to increase the response. you need to be constantly given positive reinforces
amphetamines and methamphetamines also trigger release of _______, feeling of euphoria for up to 8 hours. once effect wears off, experience irritability, insomnia, seizures, depression
dopamine
some features of schizophrenia also involve abnormalities in ______ (increase)
dopamine this dopamine plays a role in frontal/temporal lobes. effects cognitive, emotional, perceptual functions
brain releases NT called _____. produced in the _____ _____ _____ (VTA) in the midbrain
dopamine ventral tegmental area
RANT ABOUT DOPAMINE
dopamine, produced in the arcuate nucleus, is transmitted from the hypothalamus to the pituitary gland via the tuberoinfundibular pathway. the dopamine released regulates the secretion prolactin by inhibiting its release in the anterior pituitary. dopamine, produced in the substantia nigra, is transmitted from the neuron soma to axons projecting into the caudate nucleus and the putamens of the neostriatum via the nigrostriatal pathway. this pathway is associated with motor planning and purposeful movement. - substantia nigra -> motor planning dopamine, produced in ventral tegmental area (VTA) is transmitted form the VTA to the pre frontal cortex via the mesocortical pathway. this pathway is associated with cognition, affect, and negative symptoms of schizophrenia. VTA -> CORT = negative symptoms dopamine, produced in the ventral tegmental area (VTA) is transmitted from the VTA to the nucleus accumbens, the amygdala, and the hippocampus. the mesolithic pathway is associated with reward, motivation, and many of the positive symptoms of schizophrenia VTA -> LIMBIC (nucleus accumbens, amygdala, hippocampus) -> reward/positive symptoms
sigmund freud (dreams)
dreams are our unconscious thoughts and desires that need to be interpreted. little scientific support
transdermal
drug is absorbed through skin. ex. nicotine patch. drug in patch has to be pretty potent, released into bloodstream over several hours transdermal administration occurs slowly, since the drugs have to be absorbed through the skin before the effects can be felt
psychoactive drugs
drugs that can alter our consciousness and perceptions. they can alter our perception, increase our mood, calm us down, make us feel more alert, etc. classified by action and effects they have on our bodies
stimulants
drugs that excite your CNS, increase HR/BP, alertness, more awake, more energetic. can cause people to feel glittery. examples include: caffeine, amphetamines (adder all) methamphetamines (meth)MDMA (molly/ecstasy) cocaine, nicotine, THC
depressants
drugs that lower your body's basic functions and neural activity, lower CNS activity (decrease arousal/stimulation in areas of our brain) ex decreased heart rate, BP,
damaging effects of stress on our metabolism
during stress, body secretes cortisol and glucagon, which converts glycogen to glucose. glucose increases in our blood which remains floating around in blood vessels (we don't need all this extra glucose, which can exacerbate metabolic conditions like diabetes) too much blood sugar can also cause heart disease
development of self concept has 2 parts
existential self categorical self
phrenologists
each brain area is devoted to a certain personality characteristic, thought, emotion (they were wrong, but there are brain areas associated with specific tasks) - as areas of the brain developed -- they would grow and create bumps on the skull which could then be used to study the individual - early ways to study brain were limited. wait till someone died and then study it. it told them about the structures of the brain but it did not tell them how the brain functions, how the brain generates thoughts, how the brain controls the body - so to figure out how it worked -- they waited till someone got a brain injury and then the effect the brain injury had on an individual. (we don't have control of when this happens, so not the best way to study! also an accident typically causes problems with many areas - makes it hard to isolate what brain area is response for which behavioural change) cerebral localization: specific parts of the brain can control specific aspects of behaviour and emotion, thought, personality
hierarchy of organization
each position is under supervision of higher authority. not all people of an organization are equal.
labelled lines model
each taste bud has 5 axons, all which send separate test info to different parts of the gustatory (taste) cortex. remain separate to the brain. and they all synapse on diff parts of the gustatory (taste) cortex
classical conditioning (self control)
eat healthy snack every time you crave chocolate and over time you might start craving healthy snacks. refocus desires to something more in line of long term goals
lower motor neurons (LMN)

monozygotic twins
egg splits into 2 after fertilization. share 100% of genes, genetically identical
amygdala is involved with ____, aggression, mating, etc. in temporal lobe, also involved in memory/decision making, emotional reactions
emotion
further examples of coping strategies include:
emotional or instrumental support self distraction denial substance use self blame behavioural disengagement the use of drugs or alcohol
behavioural
emotions produces different behavioural responses evident from body language or facial expression. expressions vary by individual and interpreted differently culture to culture
behaviourists
empiricist, believe language is just conditioned behaviour
2 types of cues that can direct our attention
exogenous and endogenous
devil effect/reverse halo effect
even if baseline skills are same, we perceive them to all be lower (poor people) can cary over into how we see other attributes about the person. happens if overall negative impression or if one attribute is very negative
normative influence
even if you know whats right, do what group's negative actions to avoid social rejection
iron rule of oligarchy
even most democratic of organizations become more bureaucratic over time until they're governed by select few
episodic memory
event related memories, like last b-day party
modified semantic network
every individual semantic network develops based on experience and knowledge. some links might be shorter/longer for different individuals and there may be direct links for higher order categories to exemplars.
role playing
everyone plays many roles in life (we wear lots of hats, ex: we can be a brother/sister, a son, student, etc). now picture yourself in new role. first few days in new role is a bit strange/fake because we're tying to follow social quota in that role. we are trying to fit the role and sound professional. but over time, what feels like acting starts to feel like you - our behaviour of playing this rule influences our attitude overtime. what feels like acting starts to feel like you and begins to fit your attitude. - playing role as a student now become normal, playing role of a parent becomes normal over time. our behaviour became part of us. changed attitude as a result of our behaviour and carrying out that role
1 general intelligence -- spearman
evidence comes from fact people who score well on one test also tend to score well on other types of tests. ex, verbal and math skills. relative to other people, you tend to equal in both skills, although relative to oneself they might be different factor underlying these consistent abilities is called g factor (g= general intelligence)
positive emotions evoke more activity on left side
evidence: videos of positive emotions = left hemisphere increased activity on EEG. more activity on left Evidence with children: Little kids playing in group - more social kids had more activity in left hemisphere, and isolated kids more activity in right more positive, joyful, interest, enthusiastic, cheerful people had more activity in left
motivation has 5 schools of thought
evolutionary approach drive reduction theory optimum arousal theory cognitive maslow's hierarchy of needs
james lange theory -- experience of emotion is due to perception of physiological responses
ex. holding pet cat (event) -> increased HR/NT/smile (physiological response) -> interpretation of physiological response -> happiness (emotion). its not the cat making you happy... its something the cat is doing to your body that makes you happy. when sad, don't cry because you're sad, you're sad because you cry Event -> physiological response (PR) -> interpretation of PR
banging/positive
ex: a dinosaur takes out the dog - the rabbits enemy
absolute threshold can be influenced by:
expectations: are u expecting a text experience- are u familiar of the phones text vibration sound motivation: are u interested in the response of a text alertness: are u awake or drowsy
shadowing task
experiment that studies selective attention. in this task you are wearing headphones and they have 2 dif sounds in each. left ear hear one, right hears other. told to repeat everything said in one ear and ignore the other. focus on one ear and ignore the other (selective attention) based on the unattended information that we do and don't end up comprehending - we can learn about how selective attention works by seeing what they filter out in other ear. 3 theories
diffusion of responsibility theory
explains bystander effect. when individuals are in presence of others where help is needed, feel less personal responsibility and less likely to take action when needed - in a small group you don't diffuse the responsibility. you are more likely to feel personal responsibility to intervene. ex in a small group you might realize that you are only one who has practiced CPR
humour
expressing humor/jokes to be truthful and alleviate feelings but make them socially acceptable
esteem support
expressions of confidence/encouragement. things people say to let you know they believe in you. can come from family, friends but also therapists, teachers, coaches
EEG (electroencephalogram)
external, can't tell us about activity of individual/groups of neurons. can only look at sum total. can tell us about seizures, sleep stage, cognitive tasks. not invasive, we don't get a picture of a brain from this method, but we get an EEG. easier set up than MEG
social stigmas
extreme disapproval/discrediting of individual by society - comes in 2 forms 1: social stigma, 2> self stigma
fear
eyebrows raised and drawn together, wrinkles in middle of forehead, eyes open intense, mouth open, lips drawn back slightly
REM (rapid eye movement)
eyes move rapidly beneath your eyelids but most of your other muscles are paralyzed. most dreaming occurs in REM sleep, so paralyzation inhibits actions. combination of alpha, beta, and dyssynchronous waves, similar to beta waves seen when awake.
change blindness
fail to notice changes from a previous to a current state in environment (different from in attentional blindness, a subtle importance ex: don't notice when your mom gets a haircut
type I error
false positive
family
family can be shunned by society or family might shun individual themselves. may be detrimental to personal/intimate relationships, and interventions like education/therapy are important
position/vibration/touch (mehcanoreceptors) =
fast
3 types of nerve fibres
fast medium slow
A beta fibres
fast ones are thick and covered in myelin (less resistance, high conductance)
intramuscular injection is the _____ route of entry. most abused drugs are injected intravenously, however
fastest

feel more relaxed, not as focused as alertness. can also be light mediation (self induced)
by week 10 of gestation
fetal development

final behaviour you wish to train
long term memory
final stage capacity is unlimited. 2 main categories: explicit (declarative) and implicit (non declarative)
tangible/instrumental support
financial assistance/support, material goods, or services. taking some of your responsibilities so you can deal with other problems. can come from a bank, people who bring you dinner when you're sick, or lend you money between jobs
ebbinghaus
first person to look at decay in human memory. found his rate of forgetting very fast, but if he remembered it after initial stage it levelled out. in his experiment, he memorized 3 letter nonsense syllables.
hierarchical semantic network
first semantic network theory suggest that we stored information in a hierarchical way. we store info at the highest category possible.
taste bunds are concentrated at the ____ of the tongue
front (anteriorly)
alfred- binet
first to develop an intelligence test, but wasn't intending to. he developed a test in order to establish a child's mental age and measure a child's intellectual development and predict how well that do in school later on. was designed for french children
complex innate behaviours
fixed action patterns migration circadian rhythms
cannon bard theory - disagreed with james-lange, and found flaws in idea that physiological response triggered emotion
flaws they found: they first said that you could experience physiological response without emotion. ex. your heart can race if you had a long run. if only physiological response was required to produce an emotion, shouldn't anyone with a racing heat feel afraid (an emotion where your heart races as well) noticed many different emotions had same physiological responses. for example, heart racing shows feelings of anger and excitement. 2 totally different emotions physiological response system was too slow to produce emotion that seemed to happen almost instantly. ex, hearing a loud sound you would feel fear or surprise almost instantly and the physiological responses of you HR/muscle tone increase come later believed physiological response and emotion occurred simultaneously event -> PR + emotion at same time
fad
fleeting behaviour is something that becomes incredibly popular very quickly, but loses popularity just as quickly. last for short period of time, but reach influence of large number of people in that time. not necessarily in line with normal behaviour. perceived as cool/interesting by large group of people
there is ____ inside the cochlea, which gets pushed around and comes back around. ______ __ ______ splits cochlea into 2, upper and lower membrane
fluid organ of corti
physical abnormalities in schizophrenia brain
fluid filled regions have been enlarged because there is less tissue of the brain cerebral cortex (layer that is outermost part of cerebrum) seems to have decreased in size, in frontal and temporal lobes. these areas have to do with cognitive and perceptual functions which are abnormal in schizophrenia - organization of the cerebral cortex (cortical layers) particularly in frontal and temporal lobes is disturbed. typically there is a clear organization. here, there is a disorganization and thinking of layers - frontal and temporal love activity is also seen in same areas of structural/physical abnormality
attention
focus/concentrating on something at the exclusion of the other stimuli in environment
biomedical
focuses on biological, physical abnormalities
drive reduction theory/drive theory
focuses on drives vs needs. need is lack or deprivation that will energize the drive, or aroused state. that drive is the aroused state. fulfilling the drive will reduce the need. this need-drive balance is what maintains homeostasis. typically basic, essential, and physiological ex you are at the gym and need for water. trainer says you need to do more exercise. in this example, need: water, drive: thirst. doing push ups is means to fulfill drive for water
2 parts of dramaturgy
front stage back stage
fundamental attribution error
focuses only on actions of others, tendency to believe that others in out groups behave a certain way based on inherent personalities/flaws. idea of attributing character too strongly to explain another group's actions. real takeaway of study - how easy it is to think others are atrocious and evil, while people like us would only perform evil acts because they're misguided. truth is we are all misguided, all susceptible to authorities in ways that many of su would find upsetting
______ papillae are folded structures at the back of the tongue on both sides
foliate
norms can be classified in 4 groups:
folkways mores laws taboos
hypothalamus
for limbic system. it regulates the autonomic nervous system (fight or flight vs rest and digest). controlling endocrine system by triggers hormones like epinephrine/norepinephrine; responsible for hunger, sleep, thirst, sex
secondary groups
formal, impersonal, temporary, and business-like relationships, based on a limited purpose/goal. usually short term, and only see them sometimes. do a few goal-directed activities with these people
dissociate identity disorder
formerly called multiple personality disorder 2 or more distinct personalities exist in a single body. both identities have influence on persons thoughts and behaviours - extremely rare
paul ekman
found 6 main emotions which can be identified by everyone around the world happiness sadness fear disgust anger surprise consistent facial expressions across culture and easily recognizable
almost all cones are entered in the _____, which is the centre of the macula
fovea
memory of retrieval from most difficult to easiest
free recall, cued recall, recognition
histamine
from hypothalamus sends to cerebral cortex
middle ear
from malleus to stapes (3 ossicles)
external/outer ear
from pinna to tympanic membrane
psychological cause of aggression
frustration aggression principle: the idea that frustration creates anger which can spark aggression. almost anything can cause frustration. reinforcement modelling: can lead to aggression through positive reinforcement. parents who give into demands of child during temper tantrums lead to more temper tantrums in future
birth at 40 weeks
full term (37-42 weeks). before 37 (preterm) after 42 (posters). complications at both pre and postterm end of gestation - birth
taste buds can be _____ (anterior), foliate (_____) and circumvallate (back)
fungiform side
chemical signals/olfactory signals
gain info from the environment through smells. they can also release scents for communication called pheromones or to guide other members to food.
gene environment interaction
gene + environments effect our behaviour, and the role of genes + environments on behaviour is dependent on each other. (explains nature through nature)
arousal
general physiological or psychological excitement (increased HR, FASTER BREATHING, ACTIVATION OF ANS) and is known as nervous energy. increased energy/arousal increases likelihood of dominant response occurring. whether dominant response is correct or accurate depends on how easy the task is, and how well you've learned it/rehearsed it. presence of others improves performance (helps) on simple tasks and hinders it on difficult tasks/unpracticed tasks (Yerkes Dodson Law)
5 types of anxiety disorders
generalized anxiety disorder (GAD) panic disorders phobias OCD PTSD
Biological cause of aggression
genes: evidence: identical twins, if one is more aggressive the other is as well. with fraternal twins - not the cat, and we can breed animals for aggression brain structure impact on aggressive behaviour: no one brain spot controls for aggression but there are circuits in brain that can inhibit/facilitate aggression. the amygdala (part of the limbic system which is composed of structures from telencephalon, diencephalon, and mesencephalon) facilitates our fear response, and when stimulated triggers aggressive behaviour. the frontal lobe is responsible for planning, decision making, and importantly impulse control, and correlation studies have shown criminals have decreased frontal lobe activation. testosterone: a hormone released by testes in men and ovaries in women. higher in men = why men are more aggressive than women. also why 70 yo man is less aggressive than 17 adolescent one. high levels of testosterone can lead to aggression, muscle building, and wider faces (rather than long round one). can lead to irritability/assertiveness/impulsiveness, and low tolerance for frustration. drugs that reduce testosterone levels tend to reduce aggressive tendencies
biological factors of depression
genetic component 5HTTLPR gene associated with depression but only if individual is in stressful environment. decreased activation in prefrontal cortex (associated with difficulty in generating levels of activity in regard circuit to the brain) associated with NT - fewer receptors for serotonin (monoamine) and NE
drugs
genetic: family member or family history/genetic predisposition - then you have a higher chance of abusing the drug withdrawal and cravings biochemical factors - imbalance in our brains drugs like weed and heroin mimic NTs of our brain. cocaine causes the abnormal release of natural NTs like dopamine - affects our limbic system - dopamine overstimulates/activates our brain limbic system (which controls movement, emotion, motivation, pleasure). why we perceive emotions and mood altering properties of drugs. we become in state of euphoria - total happiness - if we continue to use drug, we abuse the drug. reinforcing effect - we want to constantly stimulate the brain by using drugs -- socio-culturally: curiosity, novelty of drug, rebel, poor control of user, cope with stress, low self esteem (remember: one of Maslow's hierarchy of needs, right below self actualization), relief from fatigue, feel good, and more prevalent in areas of higher poverty
employment based on technical qualifications
hiring in bureacracy is based on qualifications person has and not favouritism/personal rivalries -leads to peter principle - employee promoted until no longer able to b/c not good at their job
innate behaviour traits
genetically programmed behaviour. present at birth and requires no experience with the environment. have the following characteristics; inherited - innate behaviours are encoded by DNA intrinsic - present even if you're raised in isolation. ex pooping stereotypic - performed the same way each time inflexible - not modifiable by experience consummate - fully developed right away, at first performance. not influenced by experience - subject to change through mutation and recombination, natural selection, etc (just like all other physical traits) nausea in women during pregnancy helps them avoid toxic foods/novel strongly flavoured food in critical period of development. thought of as programmed.
fixation
getting stuck on a wrong approach to a problem. - if we can solve a problem, it typically occurs through an insight - that aha moment. insight is hard to predict and hard to encourage, particularly when you are fixated on seeing a problem from the same inefficient approach
first stage of information processing is -->
getting the input - occurs in the sensory memory (sensory register)
define convergence:
gives humans an idea of depth as well based on how much eyeballs are turned. gives sense of depth
iris
gives the eye colour. the muscle that constricts/relaxes to change the size of the pupil
cost signalling:
giving signals to others that person who's giving has resources. people have increased trust in those they know have helped others in the past. signals that the person is open to cooperation
ambient stressors
global stressors that are integrated into the environment. perceivable, but hard to control. can negatively impact us without being aware of them. stuff we just put up with in our lives. ex pollution, noise, crowding
molecule will come in and activate receptor on basal/apical cell here. basal cell sends axon through accessory olfactory bulb to _____, then mitral or tufted cell which eventually goes to the _______ (part of the brain)
glomerulus amygdala
posterior (rear 1/3) carries signals via 9th and 10th cranial nerves (_____ and _____)
glossopharyngeal and vagus
working backwards
goal state -> current state. start with goal and use it to suggest connections back to current state. used in mathematical proofs, in mazes
pathway of olfaction
goes from olfactory bulb to amygdala and the piriform cortex to the orbitofrontal cortex
in spinal cord, ____ is on inside and _____ on outside
grey white
group polarization
group makes decisions that are more extreme than any individual member in the group would want. this can turbo charge the group's viewpoints
factors that influence conformity and obedience
group size - more likely to conform in groups 3-5 unanimity - when opinions of groups are unanimous group status - why children more likely to go along with popular group. why we trust 4 doctors over 4 gardeners about our health group cohesion- if we feel no connection with group, feel less of need to go along with that group observed behaviour - whether we believe our behaviour is observed. public response 0 if we think we are met with acceptance vs shunning internal factors -- prior commitments -- feelings of insecurity - more likely to follow judgements of others our closeness to authority physical proximity legitimacy of authority institutional authority victim distance depersonalization - when learner/victim is made to be less human through stereotypes/prejudices, people are less likely to object against them role models for defiance - more likely to disobey orders when we see others doing the same
group-produced reduction of individual effort
groups experiencing social loafing are less productive, put forth less effort, and perform poorly. perhaps to hard against being the person who is doing all the work, or because you know that your individual contributions are not evaluated
positive symptoms of schizophrenia
hallucinations - sensory perceptions without stimuli like hearing or seeing not there. hallucinations are sounds or other sensations experienced as real when they exist only in the person's mind. while hallucinations can involve any of the five sense, auditory hallucinations (eg hearing voices or some other sound) are most common in schizophrenia. visual hallucinations are also relatively common. research suggests that auditory hallucinations occur when people misinterpret their own inner self talk as coming from an outside source delusions - false fixed beliefs not explainable by a person's culture. a delusion is a firmly held idea that a person has despite clear and obvious evidence that it isn't true. delusions are extremely common in schizophrenia, occurring in more than 90% of those who have the disorder. often, these delusions involve illogical or bizarre ideas or fantasies. common schizophrenic delusions include:
complicated/complex traits
happiness, aggressiveness, intelligence, characteristics of behaviour controlled by/characterized by groups of genes. those groups of genes are interacting with each other or the environment. the genes can be active or inactive. environment plays a role in activating/inactive. complex traits are associated with groups of genes and can follow mendialin polygenic inheritance patterns ex, tea bag = genes, water = environment, expression of tea is dependent on water. it is difficult to separate to what degree our genes and our traits effect our behaviour
task difficulty
harder tasks require more focus. texting while driving is more difficult than talking to a passenger in a car. also, you turn off/down radio in an unfamiliar town... because driving requires more focus/becomes a harder task when you don't know where you are going
semantic memory
has to do with words/facts. remembering simple facts
cued recall (recall cues)
having extra clues to remember the words. still have to produce an answer but still get some more cues to help you. the added cues help you retrieve the information from your long term memory. get more retrieval cues, then to do better than a free recall. for example, giving you the cue of "pl_____" and asking for what word was on a list and you answer planet
early development trajectory:
helping behaviours begin early. some newborns cry when other newborns cry (they recognize other babies distress). helping behaviour begins around age 2, children share toys and play act/helping altruism. age 4 actually begin helping says that altruism might be a normal human behaviour because it occurs at such a young age. we have a tendency to help other people without an alternative motive
meditation
helps us lower our heart rate, blood pressure, and cholesterol
assimilation
how we describe new information/experiences in terms of our current understanding/schemas.
attribution theory
how we explain behaviours of others around us - explain the behaviour of other people by breaking down our understanding/explanation of their behaviours to factors about them, and factors related to their environment/surroundings
accommodation
how we later adjust our schemas to incorporate new experiences - to remember
Syntax
how words are put together in sentences. syntax refers to the way words are placed to form language. syntax describes how words are arranged to create grammatically correct sentences. p600 response bigger with bigger violation - in ASL, this would mean combining multiple signs, gestures, and body movements to communicate effectively - all languages have some form of syntax
social facilitation
how would presence of others affect your behaviour? would it help or hinder your performance? according to social facilitation, most dominant response for particular behaviour would be shown. dominant response refers to response most likely to occur. -- occurs when individuals perform better in front of an audience
homeostasis
how you maintain temperature, heartbeat, metabolism, etc. occurs even when you are resting. takes place when you take drugs
framing effects
how you present the decision can affect decisions as well.
gallons idea of hereditary genius
human ability is heritable
optimism
humour and optimisms linked to decreased stress. nurture an optimistic outlook
strange sensations
hypnagonic hallucinations, hearing or seeing things that aren't there. ex. seeing flash of light, or someone calling your name, doorbell, etc
induced states of consciousness
hypnosis + medication are examples. does not occur naturally
dissociation theory
hypnotism is an extreme form of divided consciousness
cyclothymic disorder
hypomania + dysthymia
connection between NS and endocrine
hypothalamus
repressed memories/memory
hypothesized memories having been unconsciously blocked. due to the memory being associated with a high level of stress or trauma. the theory postulates that even though the individual cannot recall the memory, it may still be affecting them consciously. the existence of repressed memories is a controversial topic in psychology; some studies have concluded that it can occur in victims of trauma, while others dispute it. according to some psychologists, repressed memories can be recovered through therapy. other psychologists argue that this is in fact rather a process through which false memories are created by blending actual memories and outside influences. furthermore, some psychologists believe that repressed memories are a cultural symptom because there is no written proof of their existence before the 19th century some believe they can be recovered years/decades after the event, most often spontaneously, triggered by a particular smell, tase, or other identifier related to the lost memory, or via suggestion during psychotherapy
irrelevant
i see the stress but its not important
iceberg id ego superego
id: at the bottom, its the unconscious part. it develops after birth and demands immediate gratification ego - part of the conscious and unconscious. involved in our perceptions, thoughts, and judgements, and seeks long term gratification super ego - develops around age 4, and its our moral unconscious. also part of conscious and unconscious minds
looking glass self
idea that a person's sense of self develops from interpersonal interactions with others 1) how do i appear to others 2) what must others think of me? (shy, intelligent, funny?) 3) revise how we think about ourselves (based on correct OR incorrect perceptions on others evaluations)
ego depletion
idea that self control is a limited resource. if you use a lot of it, it can get used up, and less of it to use in the future which can affect a later unrelated task that also requires self control. this is true because self control requires lots of energy and focus
just world phenomenon
idea that universe is fair so people must get what they deserve - belief good things happen to good people and vice versa. some people use this to justify their actions
internalization
idea/belief/behaviour has been integrated into our own values. we conform to the belief privately. stronger than other types of conformity
strong genetic component
identical twin =/= fraternal twin identical twins raised together = raised apart adoptive child = biological parents
strong environmental component
identical twins = fraternal twins identical twins raised together =/= raised apart adoptive child = adoptive parents
problems with twin studies
identical twins treated more similarly than fraternal twins are. this would mean that monozygotic twins share even "more" of same environments than fraternal twins
strain theory
if person is blocked from attaining a culturally acceptable goal, may become frustrated/strained and turn to deviance. individuals in a group are pushed to attain certain goals, but may not have means or legitimate ways to achieve success. society values a certain behaviour but the opportunity to be successful is not made available to everyone. the lack of equal opportunity results in increased access to illegal means to achieve success
normative social influence
if we do something to gain respect/support of peers, we are complying with social norms. because of this we might go with group outwardly, but internally believe something differently
Lazarus Theory - experience of emotion depends on how the situation is cognitively appraised (labelled)
if we label emotion as good, it is positive if we label emotion as bad, it is negative how we label event is based on culture/individual differences event is the same and depending on label it produces 2 very different emotions event -> label the event (appraisal) -> emotion + PR based on appraisal + if label is + - if appraisal is - about the event
group lateness
if you arrive late at meeting but if you are with 20 other people are late too, high degree of consensus. when a lot of people demonstrate same behaviour, we are more likely to attribute behaviour to situational cause - consensus of people = attribution of external factors
extensor plantar response
if you take a hard object and scrape along the bottom of foot normal response is flexor - toes will come down on the object. but with extensor, toes extend up
belief perseverance
ignore/rationalize disconfirming facts, ex during elections learned about and then ignore facts about someone you like
types of mnemonics
imagery - crazier the better pegboard system - verbal anchors link words that rhyme with the number - ex. 1 is bun, 2 is shoe method of loci - good for remembering thins in order, link info to locations. the info you need to remember to certain stops along a route that you already know password + method of loci = 2 methods that are good for remembering things in order that you already know. verbally anchors and links words acronym - each of the letter of a popular word you know stands for the first letters of a set of words you need to remember
inattention
impacts memory formation negatively (being bored would do this)
culture and socialization
important contributions of society to our personal development, emphasises interactions between the people and culture in which we live. everyone around us (teachers, coworkers) influence our social-identity development and on a larger scale the country which we live, communities, language, attitudes of groups we belong to
permanent reflexes
important for newborns and also present throughout life breathing reflex: inhalation and exhalation eyeblink reflex: involuntary blinking of eye when something comes near head/bright light pupillary reflex: constrict pupil when bright light swallowing reflex: swallowing food happens automatically
cortical reaction
in egg there are enzymes (contained within cortical granules) that get ejected to zona pellucida and that digest the zona pellucida/ prevents sperm from binding (block to polyspermy) if this doesn't happen, zygote fails
somatosensory neurons (afferent)
in muscle spindles, form excitatory synapse in spinal cord with another neuron in the spinal cord, which sends axon out back to same muscle that was stretched, and excite skeletal muscle cells to contract - lower motor neurons (efferent)
altruism
in service of others, we feel fulfilled and gain pleasure/satisfaction
PAW feels like a rollercoaster of symptoms:
in the begging, your symptoms will change minute to minute and hour to hour. later as you recover further they will disappear for a few weeks or months only to return again. as you continue to recover the good stretches will get longer and longer. but the bad periods of post acute withdrawal can be just as intense and last just as long
agraphia
inability to write.
false information
inaccurate recollections of an event
social identity
includes the groups you belong to in our community has 3 steps
problems with adoption studies
incomplete information about biological families for adoptive children. also adoption isn't random, adoptive family sometimes matched to be similar to the biological family (of having the same community or culture). makes it more difficult to understand if something is genetic or environmentally drive.
cerebral cortex bumps=
increase cellular mass/surface area
upper motor signs hyperreflexia
increase in the muscle stretch reflexes. cause in unclear, but when muscle spindle receptors are activated, without periodic stimulation of LMNs and UMNs, they become hypersensitive and you get bigger reflex
global changes
increase myelination (faster communication of neurons - faster connections between brain area) increase in brain volume in early adolescence and then decrease later in adolescence. synaptic pruning - breaking down connections between certain neurons. focus resources on the ones we use most. what we do during teenage years - shapes us for life. what we spend out time doing - what is reinforced
damaging effects of stress on our heart
increased BP, BZV distend, so they build up more muscle and become more rigid. can lead to hypertension (HBP) and vascular disease (disease of blood vessels - get damaged with higher force of blood movement). spots attract fat and narrow blood vessels. worst place to experience this is coronary arteries - coronary artery disease
Yerkes Dodson Law
increased arousal occurs only when person's efforts are evaluated. ex if you are giving a presentation to close friends who are not evaluating you, you may not have any nervous energy, because you feel comfortable around them.
deep meditation shows increased activity in prefrontal cortex, right hippocampus, and right anterior insula
increased attention control
hypertonia
increased tone of skeletal muscles. increase muscle tension, reduce muscle stretch
bystander effect
individual may feel less inclined to take action because of presence of others in the group. the bystander effect refers to a group process in which individuals observe an injustice or a crime being perpetuated and do not intervene small group = less bystander effect. large group = more bystander effect (leads to nothing happening by any one individual and people might not even call 911)
individual discrimination
individual person acting to discriminate based on something
genes
individual units of heredity. segments of DNA that are capable of synthesizing a protein. DNA contains all the instructions of our development and in the function of our organisms and in the function of who we are. DNA is our genetic material. many of these genes (units of heredity material/DNA pieces) are linked together to form a long straight of DNA called a chromosome. as humans we have 46 chromosomes full of genes to make up who we are (23 from mother/23 from father). these chromosomes reside in almost all cells of body in the nucleus of the cells of our body.
oral
ingesting something, one of slowest routes because goes through GI tract - half hour (pill/alcohol)

caffeine
inhibits the enzyme that breaks down cAMP
I = ?
initial intensity of stimulus delta I = JND
temperament
innate disposition, our mood/activity level, and is consistent throughout our life
id
innate. the reservoir of all psychic energy. the id seeks to discharge tension arising from internal needs or external stimulation. it is made up of all instincts and wants to get rid of all uncomfortable feelings. (this is called a "drive reduction theory") - the pleasure principle: to gain pleasure or avoid pain. to accomplish this it uses: reflex actions (for instance sneezing) - primary processes (forming a mental image of the desired object) - wish fulfillment - the image of your desire which temporarily restores comfort
treisman's attenuation theory
instead of complex selective filter, have an attenuator - weakens but doesn't eliminate input from unattended ear. then some gets to perceptual processes, so still assign meaning to stuff in unattended ear, just not high priority. then switch if something important - treisman's attenuation theory replaced the selective filter with an attenuator, which selectively allows the attended message to be processes to a greater extent than the unattended message sensory register -> attenuator -> perceptual processes -> -> conscious
organizations
institutions designed for specific purpose, collective goal, and try to achieve maximum efficiency.
operant conditioning
instrumental conditioning focuses on the relationship between behaviour and their consequences, and how those in turn influence the behaviour
neurotic defence mechanisms
intellectualization - taking intellectual aspects and detaching to the emotional aspects of the situation. separating emotion from ideas rationalization - making yourself believe you were not on fault - avoids blame to oneself. can have flat logic or false reasoning regression - acting like a baby in some situations ex throwing temper tantrum, start whining repression - unconscious process where thoughts pushed down to unconscious displacement - person angry at someone but displaces it to someone else (a safer target) ex mother who is mad at her husband gets mad at her child reaction formation - unconscious feelings that make person to complete opposite - ex a mother who bears an unwanted child may react to her feeling son guilt for not wanting it by being extremely solicitous and overprotective to convince herself that she is a good mom - ex a person who doesn't like immigrants might start to volunteer at an immigration centre
fixed mindset
intelligence is biologically set and unchanging - praise that reinforces a fixed mindset describes characteristics and actions as innate and unchangeable
growth mindset
intelligence is changeable if you learn more - praises efforts, perseverance, improvement and strategies rather than the end result
IQ stands for
intelligent quotient
theory of planned behaviour
intentions + implications: we consider our implications of our actions before we decide on how to behave. the best predictor of our behaviour is the strength of these intensions and implications intensions are based on 3 things - our attitudes towards a certain behaviour (ex I like/favor studying) subjective norms: what we think others think about our behaviour (ex my friends think studying is a waste of time) -perceived behavioural control (how easy/hard we think it is to control our behaviour). ex I also have to work 40 hours this week on top of studying
preparatory stage
interaction through initiation ex play with pots and pans when parents are cooking. as they grow older, focus more on communication with others instead of simple imitation, and get practice using symbols (gestures/words). can't take perspective of others
society
interactions between self and society like education/employment/health and stigmatizing views can affect individual to get a job, in healthcare, etc. a great intervention to stop societal level stigma is the use of legislation and anti-discrimation laws
intrinsic motivation
internal motivation
ICD-10
international classification of diseases, 10th revision, system from the WHO, 11 top level categories
Sexual response
investigated by master & johnson. they studied 100s of male and female volunteers during sexual activity. they measured the physiological indicators and they turned the results into the sexual response cycle biological: sexual response cycle - first part of cycle is excitement phase, marked by increased heart rate, muscle tension, BP, etc second is plateau then 3rd - orgasm 4th is resolution/refractory period M&J also noted sexual drive/activity was related to testosterone for women and men (sexual activities increased testosterone which in turn increased the sex drive) also have genetic predisposition to sexuality, and found by studying at homosexuality sociocultural - varied sexual response due too: age, cultural background (certain practices acceptable in certain cultures but not others), stimulus (determined by how responsive we are to visual/tactile stimuli), emotions (psychological influence) and desires (to procreate or not) hormones: prolactin is related to sexual gratification and is associated with relieving sexual arousal after an orgasm endorphins produce feelings of euphoria and pleasure, and are related post orgasm oxytocin is released after an orgasm to facilitate bonds and feelings of connectedness between sexual partners
neurodevelopment disorders
involve distress/disability due to abnormality in development of nervous system. includes intellectual disability, autism spectrum disorders, and ADHD - autism spectrum disorder is characterized by a variety of issues related to social and communication abilities, and first symptoms of the disorder typically include delayed language development and unusual communication patterns specific learning disabilities: all specific types removed from DSM V the specific learning disorder dyslexia is characterized by problems with accurate or fluent word recognition, poor decoding, and poor spelling abilities dyscalculia - mathematics learning disorder. removed dysgraphia - writing disorder, removed developmental coordination disorder is characterized by difficulties in acquiring and coordinating motor movements
implicit memories/non declarative
involve things you may not articulate. a type of memory in which previous experiences aid in performance of a task without conscious awareness of these previous experiences. evidence for implicit memory arises in priming, a process whereby subjects are measured by how they have improved their performance on tasks for which they have been subconsciously prepared - such as riding a bicycle
schizophrenia spectrum and other psychotic disorders
involves distress/disability from psychosis. psychosis involves delusions (fixed false beliefs not explainable by experiences/culture ex. ones thoughts are controlled by someone else or "i have superpowers"), hallucinations (sensory perceptions without any stimuli ex hearing voices without stimuli). with psychosis disorganized thinking can occur and negative symptoms (decreased emotional expression, decreased motivation, decreased social behaviour). schizophrenia has many of these features while other psychosis disorders have some
motivational interviewing
involves working with patient to find intrinsic motivation to change. very focus, goal directed therapy. few sessions and can be doorway for patient to engage in other treatment
sour and salty rely on ____ _____
ion channels
smell and taste do not synapse on the thalamus and hence are both _____, while vision/hearing/touch are _____
ipsilateral contralateral
phobias
irrationally afraid of specific objects or specific situation. focused anxiety can be debilitating (ex phobia of leaving your home) or can have a normal life (ex phobia of snakes) tend to form a pattern. people tend to have phobias of specific subtypes of things typically - generally associated with fear of animals, insects, blood, heights, or enclosed spaces. these are common but there are more. people get by by avoiding the source of their phobia social phobias: fear of different social situations. not as easy to avoid. ex shyness, or intense fear of being scrutinized by others people avoid talking to people or places where they might be judged or situations that might lead to embarrassment
what is light

sensitization
is when a person seeks to learn about, rehearse, and or anticipate fearful events in a protective effort to prevent these events from occurring in the first place
instinctual drift
it is the phenomenon whereby established habits, learned using operant techniques, eventually are replaced by innate food-related behaviours. so the learned behaviour "drifts" to the organism's species-specific (instinctual) behaviour

xenocentrism
judging another culture imposition of ones own cultural values on another culture
ethnocentric

drowsiness
just before falling asleep/after waking up. can also be self induced in deep meditation
hippocampus
key role in forming new memories. convert STM (short term memory) -> LTM. if destroyed, still have old memories intact, just can't make new ones (anterograde amnesia)
vygotsky
language and thought are both independent, but converge through development. eventually learn to use them at same time via socialization - believed children developed language through social interaction with adults who already knew language. through the interaction, they learnt to connect the thoughts and the language they eventually learn
strong linguistic determinism (sapir whorfian hypothesis)
language determines thought completely. people understand their world through language, and in turn shapes how we experience the world. -- believes linguistic structure determines how and about what an individual is able to think
biological factors
lateral hypothalamus (LH, acronym: one with missing LH - lacks hunger, son normal functioning LH controls that we start eating. you'd be skinny with an "L") in normal conditions, LH sends positive signal to us to start eating ventromedial hypothalamus (VMH), when functioning properly, it signals to us to stop eating. lectin present in high amounts in blood when full (apetite suppressing hormone) another hormone is insulin. brain can detect level of insulin to see amount of sugar and fat store in blood. too much insulin = lots of sugar/fat store metabolism rate. in dieting we get a slowdown in metabolism. makes it easier for people to gain weight when resuming normal eating. genetic predisposition to our weight, set point influenced by parents
under the microscope (PD), we see "diseases neurons" which are degenerating in the substantia nigra. often contains _____ ______
levy bodies abnormal structures inside dopaminergic neurons of substantial nigra. the lew bodies contain a protein alpha synuclein, a normal protein present in brain cells under normal conditions are clumped together in PD
2 instinctual drives motivate human behaviour
libido - neutral energy source - fuels energy of mind for motivation for survival, growth, pleasure, etc death instinct: drives aggressive behaviours fuelled by unconscious wish to die or hurt oneself/others
eros drives:

down regulation
light adaptation. when its bright, pupils constrict and the densensitization of rods & cones (become desensitized to light)

literal meaning (freud theory of dreams)
prosody
located on right hemisphere. concerned with larger units of speech like syllables. contribute to linguistic functions such as intonation, tone, stress, and rhythm. prosody may reflect various features of the speaker or the utterance: the emotional state of the speaker; the form of the utterance; the prince of irony or sarcasm, emphasis, contrast, and focus; or other elements of language that may not be encoded by grammar or by choice of vocabulary.
left brain
logical sequential rational analytical objective looks at parts
first impressions are: (3)
long strong easily built upon -- called primary bias, first impression is more important than later data

long term potentiation
materialist
look at what happens in brain when people think/speak/write
informative influence
look to group for guidance when you don't know what to do and you assume the group is correct
other (dreams)
maintain brain flexibility - allows us to learn and be creative when we are awake consolidate thoughts to long term memory, and cleaning up thoughts. people who learn + sleep retain more than those who do not sleep. but role of REM is unclear preserve and developing neural pathways. because infants constantly developing new neural networks, spend most of time in REM memory consolidation theorists believe memory consolidation in deep sleep
excessive orderliness, obsessionality
maintains strict order, tight self control or high level of predictability through order and planning, excessive adherence to routine or trial, or undue caution. devotes inordinate time to finding the best way to accomplish tasks or avoid negative outcomes
depression, a major depressive order
major cause of distress, disability, and death from suicide. prototype of disorder category of depressive disorders related symptoms of depressive mood: feelings of hopelessness, loss of interest in activities. our understanding of cause of major depressive disorder is limited. no consistent abnormalities in brain tissues, but scans have suggest functional abnormalities in brains
change environment (self control)
make object of you temptation harder to get while making better/healthier options easier to get.
2 identities in DID are distinct from each other. each has its own:
mannerisms emotional responses distinct "physical changes" - not actually different physical differences but one identity could identify as right handed and another as left handed denial - denying the existence of the other identity. not aware of other distinct personalities exist within that person
perceived control
many studies show lack of control associated with higher stress. low SES increases stress shown by Robert Sapolsky with Baboons who had social hierarchy structures similar to humans. primates at the bottom of the barrel socially experienced much more stress than the ruling elite baboons. the white hall study showed the exact same effect based on relative rank in the workplace in humans in britain. suggestion: look for areas of life where you can take a little bit of your control. "king of your own castle"
biological theory
many variations to this theory, some relate to the brain and some to behaviour (the evolutionary psychology approach) instead of traits ex a dominant psychological (behavioural) biological theory by buss: evolutionary psychology theorizes that males + females have different mating strategies that influence costs associated with passing on genes. males can have many mates, females more selective due to cost of pregnancy
pituitary
master gland anterior (FLAT-PEG) FH, LH, ACTH, TSH, prolactin, endorphins, GH GH - the pituitary gland triggers the growth spurt that occurs during adolescence posterior: ADH + oxytocin (intermediate lobe) pars intermedia - MSH (melanocyte stimulating hormone)
nature
maturation. genetic factors/anatomical/neurophysiological/biological traits that drive development. identical twins walk on the same day. children all over the world develop motor skills in the same time and same order. blind children tend to show same timing and progression of motor development. - infants need to have muscles that are developed to walk or to have bowel control.
basic functions =
motor (control of skeletal muscle) sensory (the senses) automatic (reflexes)
frontal lobe
motor cortex (body movements), prefrontal cortex (executive function, surprise/direct other areas of brain), broca's area (speech production)

means they can live at home and come inq for treatment
tolerance
means you get used to a drug so you need more of it to achieve the same effect shift in the does response curve that causes decreased sensitivity to a drug due to exposure
self serving bias
mechanism of preserving our self esteem, more common in individualistic cultures. if we succeed its due to our internal/personal qualities, but if we fail no hit on self esteem because likely to do with things outside of our control -individualistic societies tend to demonstrate a great degree of self serving bias. more important in individual societies because of their emphasis on achievements and success
pain and temperature receptors end in big uncovered terminals, don't have big structures like ______

somatic symptom disorder:
mental disorders manifesting in physical symptoms can be any symptom. wrist pain or general feeling of fatigue may or may not be able to explain what we see (the physical condition). may or may not be related to a physical condition must cause functional impairments. stops them from going to school or enjoying life. these individuals have excessive levels of all of the following symptoms: worried (excessively), have extreme levels of anxiety, and spend lots of time and energy worrying/stressing about these symptoms, etc
schemas
mental models frameworks for us to organize and interpret new information. piaget belief of cognitive development was in the development of schemas. to develop these, you need to be able to grow/change them - which happens through assimilation and accommodations
heuristics
mental shortcut that allows us to find solution quicker than other 2. reduces number of solutions we need to try by taking an approach as to what possibilities could exist and eliminates trying unlikely possibilities. don't guarantee a correct solution, but they do simply complex problems and reduce total number of solutions we will try in order to get to a more manageable number.
the mesocorticolimbic pathway is affected in schizophrenia
mess = midbrain, where VTA. specifically, the soma of neurons that use dopamine are located at VTA cortico= cerebral cortex, axons project to frontal and temporal love of brain and relate dopamine to cerebrum areas. limbic= collection of structures inside of brain involved in emotions/motivations/etc often divided into mesocortical pathway (VTA to the frontal love) and mesolithic pathway (VTA to limbic structures) abnormal activity of mesocorticolimbic pathway. one way of thinking about schizophrenia is abnormal activity is mesocorticolimbic pathway leads to dysfunction in parts of frontal cortex that cause cognitive symptoms, and limbic structure causes negative symptoms, and abnormal activities in temporal cortex causes positive symptoms. -abnormalities are likely much more complicated causes: genes, physical stress during pregnancy (such as infection during pregnancy and psychosocial factors (negative family interaction styles effect development of brain) - poverty and schizophrenia link. casualty is not well known
message characteristics
message itself, clarity, was it logical, how well thought message it. also includes how well written it was, does speaker have good grasp of grammar, appropriate vocabulary, length of talk, etc
hormone concentration is regulated by:

algorithm
methodical approach. a logical step by step procedure of trying solutions until you hit the right one. not efficient, but are guaranteed to find the correct solution eventually.
anger
meyer friedman and ray rosenman were testing notion that stress is associated with increased vulnerability to heart disease, and when they interviewed the patients during their study and characterized them as either type A or B type A: easily angered individuals, aggressive, competitive Type B: easy going those who had heart attacks later were mostly type A/ the toxic component of type A personality was being prone to hostility and anger. accompanies the fight aspect of sympathetic response
hypomania
mild forms of mania is sometimes not that bad. lots of energy and don't need to sleep a lot so you get lots of work done. you also feel good. creativity. results in mania at times, but sometimes does not develop into it
4 things we do to reduce cognitive discomfort
modify our cognitions: change/alteration in the cognition (thinking process) in a person's action/behaviour to reduce the discomfort a person has with that attitude/behaviour trivialize: make less important/make trivial change the importance of their cognition add: adding more cognitions to make contradictions more comfortable deny: denying the facts
gene regulation
modulatory world of gene expression (gene expression modulated by environmental factor). greatest achievements in clarifying the modulatory factors we have had mapped our entire gene - gene mapping of all genes on the 46 chromosomes. because of genome now we can look at populations which share traits and not have to relay on twin/adoption studies to narrow down heritability of traits. now, we can look at population of shared traits and look at genes that code for those traits and compare/contrast those genes - scientists who study gene mapping look at populations with shared traits and compare their genetic profiles. they also may look at damage to DNA in a person's genome
visual cues that we receive but do not need 2 eyes for are _____ _____
monocular cues
faster rout of entry =
more addictive potential
ill defined
more ambiguous starting and or/ending point. an ill defined problem does not have an obviously stated goal or lacks relevant information to solve the problem
play stage
more aware of social relationships, reflected in children tendency to pretend play as others like fire fighters, doctors, etc. mentally assuming perspective of others and acting based on their perceived point of view. focused on role taking: mentally taking perspective of another person and acting on that perceived view point way beyond immigration. they create social interactions (not just mimicking) children consider attitudes, belief, and behaviours of individuals closest to them
elaboration likelihood model of persuasion (ELM)
more cognitive approach - focuses on the why/how of persuasion 2 ways in which information is processed central route of persuasion: the degree of attitude change depends on quality of the arguments by the persuader. how much we are persuaded depends on quality of persuasion. argument/words are central! peripheral route of persuasion: looks at superficial/expertise/non-verbal persuasion cues, such as attractiveness/status of persuader. the doctor himself is peripheral (he is the one delivering the words)
encoding is more successful when
more cognitive effort is actively used. combining encoding strategies is more useful than using only one
back stage

moves back and forth at same frequency as stimulus. it pushes the elliptical window back and forth
problem solving
moving from a current state to a goal state
neurochemical lesions
much more precise method!! exitotoxic lesions (excitotoxins are chemicals that bind to glutamate receptors and cause influx of calcium that causes so much excitement that kills the neurone/excites it to death - one examples is kainic acid. destroys cell bodies but doesn't influence axons passing by. don't severe connections like in knife cuts/radiofrequency lesions also oxidopamine (6-hydroxydopamine) selectively destroys dopamine and NE neurons. can model parkinson's diseases - oxidopamine is very similar to dopamine. in reuptake, the presynaptic cell takes the oxiopamine back for recycling (normal mechanism) but then this neuron is destroyed. it destroys substantia viagra neurons completely
hypnic jerks
muscle twitches you sometimes experience as you fall asleep
fungiform papillae are ___ shaped
mushroom
conversion disorder
must look like neurological symptoms only - like problems with speech, swallowing, seizures, paralysis neurological symptoms that we see are incompatible with any known neurological or mental condition. we cannot explain these symptoms based on test or clinical exam sometimes have a level of psychological stress or traumatic event resulting in manifestation of neurological symptoms the DSM5 criteria for conversion states the individual must exhibit at least one symptom of altered voluntary motor or sensory function that shows internal consistency, causes distress or impairment, and cannot be explained by another mental or medical disorder. the ICD-10-CM categorizes by symptom type, with weakness (or paralysis) and abnormal movement (tremor) listed as specific symptom types
what causes schizophrenia?
nature - genetic component nurture - environmental component goal of researchers is to isolate genes and the environments. look at one without the other to see what causes the disorder monozygotic twins vs dizygotic twins - can hold environment constant. examine effect of genes - if schizophrenia was genetic, we would expect to see different rates in identical vs. fraternal twins. higher in identical twins. - but if environmental, similar rates of disorder in both sets of twins. wouldn't matter if they were identical vs fraternal. they share 100% of the environment
geographical proximity
nearness is most powerful predictor of friendships and relationships
intramuscular
needle stuck into muscle. can deliver drugs to your system slowly or quickly quick delivery - epi pen slow delivery - vaccines (while muscles are sore)

fast adapting
neuron fires as soon as stimulus start, then stops, starts again when swim stops
retroactive interference
new learning impairs old info. refers to later information interfering with memory for earlier information
free recall
no cues in recalling. better recalling first items on a list (primacy effect) as well as last few (recency effect). harder to remember things in the middle of the list. recency effect is not as strong if there is an interpretation after list is called.
latent period
no focus on libdo. a period of exploration, libido present but directed into other areas such as intellectual pursuits and social interactions. important in development of social and communication skills. children concerned with peer relationships, hobbies, and other interests. play is between same gender children - fixation doesn't develop into adult fixation
implicit memories are
non declarative unconscious
permissive parenting/indulgent parenting
non-directive and lenient. few behavioural expectations for child
assortative mating
nonrandom mating where individuals with certain phenotype/genotype/similarities/genes/physical appearance tend to mate with each other at a higher frequency, ex large animals mate with large animals and small animals mate with small animals - can result in inbreeding which is problem that occurs if animals too genetically similar mate. can be harmful to species overall. increase likelihood of harmful recessive traits being passed on to offspring.
sperm binding
when sperm comes in contact with zona pellucida. sperm binds to zona pellucida
mores
norms based on some moral value/belief (dependent on groups values of right and wrong). generally produce strong feelings. usually a strong reaction if more is violated ex truthfulness (tell true because its right thing to do, when public figures are not truthful causes outrage because the figure has done something wrong) don't have serious consequences
laws
norms still based on right and wrong, but have formal/consistent consequences. ex public figure lies under oath. done something morally wrong but also violate laws of court. there is a punishment for the crime. violating can be some (j walking) or severe (murder). there is not always outrage when a law is violated - depends on the law
frustration aggression hypothesis
not personality based, but more emotional display aggression towards other people - scapegoating. often seen in times of economic hardship
collective behaviour
not the same as group behaviour, because of a few reasons first, it is time limited, and involves short social interactions while groups stay together and socialize for long periods of time collectives can be open, while groups can be exclusive collectives have loose norms (which are murkily defined) while groups have strongly held/well defined norms
blastocyst
now the inside = cluster more and you develop an inner cell mass and blastocoel (hollow space). zona pellucida disintegrates the inner cell mass then make an amniotic cavity and the bottom cells of the inner cell mass differentiate into hypoblasts. the cells above hypoblasts are called epiblasts bilamar disk (epiblast + hypoblast) primitive stream forms: where the epiblast cells start to migrate
acetylcholine

attentional capture
occurs when attention is attracted by the motion of an object o stimulus
closure
objects are grouped together are seen as a whole. mind fills in missing information
proximity
objects that are close are grouped together, we naturally group the closer things together rather than things that are farther apart.

occurs at levels of high light
scotopic vision
occurs at levels of very low light
fundamental attribution error
occurs when a person assigns too much weight to internal causes rather than external factors when looking for causes of another person's behaviour
groupthink
occurs when maintaining harmony among group embers is more important that carefully analyzing problem at hand. happens in very cohesive, insulated groups. often have important/respected leaders, and in the interest of group "unity" individuals suppress/sensory their own opinions - first suggestion proposed by leader is adopted. especially if there is little hope finding a batter solution. not the most effective way to make a decision and can explain whats wrong with congress in the US to avoid group think: bring in outsiders/experts, have the leader of the group not disclose opinion, discuss what should be done in smaller groups
substance use disorders
occurs when use of the drug causes a serious/real degree of impairment in functioning in life, at work, school, or home. not everyone experiences this
transduction
occurs whenever energy is transformed from one form to another, in this case, light energy is transformed to electrical energy by rods and cones
independent stressor
occurs without the person's influence. equal amounts.

off brain
prestige
often based on occupation. minority group members have lower paid jobs typically

olfactory epithelium cribriform
when dark, rod turned ___ ->, ON CENTRE bipolar cells ____, OFF CENTRE bipolar cells ______
on inactive active
the phototransduction cascade is the process of rod turning from ____ to ___
on to off
adrenal glands
on top of kidney (adjacent to kidney): ACTH acts on adrenal cortex (steroids (fluid volume; stress resp) glucocorticosteroids like cortisol) and medulla (catecholamine's hormones) the adrenal gland plays a supportive role in development of muscle and bones
each post acute withdrawal (PAW) episode usually last for a few days
once you've been in recovery for a while, you will find that each post acute withdrawal episode usually lasts for a few days. there is no obvious trigger for most episodes. you will wake up one day feeling irritable and have low energy. if you hang on for just a few days, it will lift just as quickly as it started. after a while you will develop confidence that you can get through post acute withdrawal, because you'll know that each episode is time limited
opitates/opioids
opitates - natural opioid - synthetic like depressants: decrease CNS function, decrease HR/BP, cause relaxation, induce sleep (hence can be used to treat pain and anxiety) but it is NOT a depressant. work on different mechanisms at the neurochemical level Analgesic - reduce perception of pain ex. heroine, codeine, morphine, oxycodone used to treat pain because they act at body's receptor sites for endorphoines
dis-assortative mating (non assortative mating)
opposite of assortative mating - situation where individuals with individuals with different or diverse traits mate with higher frequency than with random mating
inside rod are a lot of ____ disks stacked on top of one another
optic
social cognitive theory
originally called social learning theory theory of behaviour change that emphasizes interaction between people and their environment. unlike behaviourism (where environment controls us entirely). condition is also important - social factors, observational learning, and environmental factors (ex opinions/attitudes of friends and family) can influence your beliefs
impression management
our attempt to control how others see us on the front stage. do this because we want to be viewed in a positive way. there are multiple social situations which require different scripts from you as an actor and hence there are multiple front stages, and you have to play a different front stage role every time. we manage our sense of self in social interactions
constancy
our perception of object doesn't change even if the image cast on the retina is different. different types of constancy include size constancy, shape constancy, colour constancy

heredity
passing traits from parents/ancestors to offspring through genes.
Factitious disorder
patients want to be sick. the patient will falsify or disease their signs or symptoms to get a diagnosis/treatment ex. they might injure themselves, falsify tests. this is often called munchausen's syndrome muchausen's by proxy - when one person makes another person look ill so medical attention/treatment provided further for another individual people do this to be in sick toll (not for money)
sleep debt
paying back sleep
conformity
peer pressure tendency for people to bring behaviour in line with group norms. powerful in social situations. we use social situations (especially ones with peers) to determine what is acceptable, when to question authorities, and get feedback on behaviour. - this is why it is important for people to have positive peers. if group behaviour is positive, then there will be peace, harmony, happiness, negative peers = negative behaviours, which can be catastrophic
anger
penetrating stare, eyelids tense, lips pressed together
socio cultural cause of aggression
people act more aggressively in groups (ex riots) - deindividuation you gain an anonymous status when you are with large group of people. if people around individual act poorly, individual might act poorly too. this also explains why there is poor behaviour on the internet (they are anonymous here, and those around them model poor behaviour) deindividuation: when an individual loses self awareness social scripts: when people are in new situations they rely on social scripts, or instructions provided by society on how to act. ex violent video games, model aggressive behaviour for them, viewing media can give them example of how they should act.
kin selection
people act more altruistically to close/kin than distant/non kin people - same when people share last names (especially if rare names) morphing face as increase trust we have in other person
reciprocal altruism
people are also more cooperative if they will interact with that person again in the future. giving with expectation of future reward. -we feel more obliged to help someone else if they have helped us. - this is why charities send out small gifts.

persistent changes in our body that result our experiences. not present at birth, but acquired after experiences with the environment. have the following characteristics: non inherited - acquired only through observation/experience extrinsic - absent when animals are raised in isolation, ex social skills permutable - pattern/sequence that is changeable adaptable - capable of being modified in response to changing conditions progressive - subject to improvement or refined through practice over time.
cognitive flexibility
perspective change is huge in our perception of what is stressing us out. good way is working with counsellor
deutch and deutch's late selection theory
places broadband selective filter after perceptual processes. this means that you DO register and assign everything meaning but then selective filter decides what you pass on to conscious awareness -moved the selective filter from before perception to after perceptual processes sensory register -> perceptual processes -> selective filter -> conscious some problems - this whole process has to occur quickly, but given limited resources of attention and knowing our brains are super efficient it seems wasteful to spend all that effort assigning meaning to things first which you won't ever need
in attentional blindness is the inability to recognize an unexpected object, event or stimulus that is in _____ _____
plain sight -- this is due to a psychological lapse in attention, rather than a defect or deficit in sensory perception
McDonaldization
policies of fast food organizations have come to dominate other organizations in society. primarily, principles of efficiency, calculability, predictability, uniformity, and control - these principles have come to dominate everything, from medicine to sporting events to entertainment.

prefrontal cortex
specific changes during puberty:
prefrontal cortex: developed during adolescence. responsible for higher order cognition (thinking about future, planning, decision making, ability to inhibit certain behaviour and focus on long term goals). develops into early 20s. explains why teenagers show poor judgment limbic system amygdala: responsible for emotions/emotional responses. explains why teenagers are moody and have emotional outbursts (yelling at parents, slamming door) hypothalamus: regulates endocrine system (hormones) limbic system also includes other structures, but these top 2 are important corpus collosum connects right/left hemisphere. changes to connections associated with language/language learning. these connections develop until puberty
as we grow up, our belief on how others perceive us is more important, this happens through 3 stages
preparatory play stage game stage

parkinson's disease
progressive neurological disorder involving motor abnormalities and mental dysfunction (neural) too. most common neurological problems are slowed movements, a type of tremor, increased muscle tone, abnormal walking, and poor balance (leading to falls). muscles are stiffer and slow with tremor. later in disease when motor abnormalities of cognitive, emotional, and autonomic functions
projection
projecting own feelings of inadequacy on another
immature defence mechanisms
projection - throw your attributes to someone else - like accusing another person of being jealous when you are the one being jealous - can cause projection identification 0 that person targeted with projection can start believing, feeling, having thoughts of the attributes that were projected to them. ex the person now actually feels jealous and the person can believe " im jealous" passive aggression - aggressively doing something for someone and filing to do it or doing it slowly. passive way to express anger
convergent intelligence
proposed by Guilford to describe IQ test related intelligence, such as puzzles, vocabulary words, and arithmetic
hans eysenck
proposed extroversion level is based on differences in the reticular formation (controls arousal and consciousness) - introverts are more aroused than extroverts so they seek lower levels of stimulation
raymond cattell
proposed we all had 16 essential personality traits that represent basic dimensions of personality. turned this into the 16 personality factor questionnaire

protein/polypeptide (small-large) steroid: from cholesterol (lipid - not charged and can pass freely through membrane) tyrosine derivative: from tyrosine. thyroid hormones and catecholamines (adrenal medulla produces this)
LSD
prototypical hallucinogen. interferes with serotonin, which causes people to experience hallucinogens hallucinogens are visual instead of auditory
written rules and regulations
provides clear expectations but stiffens creativity and rules become too important
cognitive behavioural therapy
psychological treatment for drug treatment. addresses both cognitive and behavioural components of addiction. patients learn to recognize problematic thought patterns and develop more positive thought patterns and coping behaviours. they learn to anticipate problematic situations and to self monitor for cravings so they can apply their coping strategies early.

negative feedback
rate or process that needs to be controlled to decrease product. ex in our body - negative feedback is put into place to inhibit production of product
modified semantic network
rather than hierarchal, says every individual semantic network develops based on experience and knowledge. means all ideas in head are connected together. when you activate one concept, you pull related concepts with it. called spreading activation (can explain false memories, or remembering wrong but related info)
pragnanz
reality organized reduced to simplest form possible. ex. olympic rings, where the brain automatically organizes these into 5 circles, instead of more complex shapes
egg cell
really big. not made for motility. cell = 10X more massive. egg has genetic material and a thick outer coating (zona pellucida that is a thick layer of glycoproteins - protein with branching sugar chains). deep to zona pellucida - plasma membrane. once sperm gets through plasma membrane = fertilization. egg cell has mitochondria (200K mitochondria) but also other organelles
decline
recall becomes more difficult (although recognition is stable), episodic memories impaired (forming new episodic memories is difficult, old memories stable). processing speed (older people have a harder time outputting a response) and divided attention (becomes harder to switch attention between task and become easily distracted. also prospective memory (remembering to do thins in future) is decreased.
drugs
substances that include alcohol, tobacco, cannabis, opioids, stimulants, hallucinogens, inhalants, sedatives, caffeine

lexical access
refers to identifying a word and connecting it to its meaning, which has been stored in long term memory
agents of socialization
refers to parts of society that are important for socialization (the process of learning the norms and values in a society)
low effort syndrome/low effort coping
refers to the coping responses of minority groups in an attempt to fit into the dominant culture. for example, minority students at school may learn to put in only minimal effort as they believe they are being discriminated against by the dominant culture
transformationalist grammar:
refers to the different ways that words can be arranged to convey the same information language is an innate ability
3 main types of innate behaviour
reflexes - sensory and motor nerve loop response without thinking (ex. knee jerk response) orientation behaviours - regulating specially in our environments ex kinesis, our change in speed (orthokinesis), change in rate turning (klinokinesis). can be in response to a stimulus (like tripping on a sidewalk - your body would change speed/kinesis) ex positive taxis and negative taxis - movement towards/away from stimulus respectively. ex insects and light. insects have positive taxis towards light (phototaxis) fixed action pattern (FAP) - sequence of coordinated movement performed without interruption. similar to a reflex, but more complicated. ex praying mantis. any prey-sized movement preying mantis experiences elitists a strike response, once strike initiated - cant be changed/altered at all.

released by lots of nuclei from all over the brainstem (midbrain, pons, and medulla) called raphe nuclei to cerebral cortex release serotonin. raphe nuclei also send serotonin to other parts of the nervous system (like sex = messy. from everywhere done low (brain stem)
minnesota study
religiosity in monozygotic twins has a coefficient of correlation value of 0.49 based on minnesota twin studies reared apart data personality in monozygotic twins has a coefficient of correlation value of 0.50 based on the minnesota twin studies reared apart data information processing speed in monozygotic twins has a coefficient of correlation value of 0.56 based on the minnesota twin studies reared apart data intelligence in monozygotic twins has a coefficient of correlation value of 0.69 based on the minnesota twin studies reared apart data
intuition
relying on instinct. high chance of error
deprivation
removing the object of temptation completely is problematic. can make you want it more, and leads to ego depletion (takes lot of effort to deprive of yourself something completely). this is probably why those on strict diets likely to fall to temptation
partial report technique
report one part of a whole field in cued recall. the partial report condition required participants to identify a subset of the characters from the visual display using cued recall. the cue was a tone which sounded at various time intervals (50ms) following the offset of the stimulus. the frequency of the ton (high, medium, or low) indicated which set of characters within the display were reported. due to the fact that participants did not know which row would be cued for recall, performance in the partial report condition can be regarded as a random sample of an observer's memory for the entire display. this type of sampling revealed that immediately after stimulus offset, participants could recall most letters (9/12) in a given row suggesting that 75% of the entire visual display was accessible to memory
conjunction fallacy
representativeness heuristic can lead to this this means co-occurence of 2 instances is more likely than a single one. people tend to think the probability of 2 events occurring together is higher than the probability of one alone
happiness
represented by, raised cheeks, elevated concerns of mouth (sometimes wrinkles on outer corner of eyes, and teeth exposed)
damaging effects of stress on our reproductive
reproduction huge energy expense in women, so this gets shut down during stress repose in women - FSH/LH and then estrogen/progesterone can be inhibited which reduce reproductive abilities boys have a reduced testosterone as well, but precise levels of testosterone not required so never really reduced to the point of infertility. impotence/erectile dysfunction also often caused by stress because your blood vessels are being constricted (less blood flow to penis) and allows more blood to remain in core. impotence usually due to stress in US
endogenous cues/internal cues
require internal knowledge to understand the cue and the intention to follow it. ex, a mouse arrow, would need internal arrow of what an arrow is to follow it and to know its not just a random line - endogenous attention is driven by top-down or internal events, ie the cocktail effect
inpatient treatment
require residence at a hospital or treatment facility
whole report technique
required participants to recall as many elements rom the original display in their proper spatial locations as possible. participants were typically able to recall 3-5 characters from 12 character display (35%). this suggests that whole report is limited by a memory system with a capacity of 4-5 items
anchoring and adjustment heuristic

parasympathetic
rest and digest, opposite effects of Sympathetic pupils constrict increased salvation decrease respiratory rate/decreased hear rate (back to normal) increase glucose storage (digesting food) decrease in adrenaline increase digestion
sympathetic
result due to fear pupils dilate decrease in salivation increase respiration rate increase heart rate increase glucose release increase adrenaline and norepinephrine decrease in digestion

result in distress/disability from sleep related issues. insomnia and breathing related sleep disorders, abnormal behaviours during sleep
when _____ changes shape, rhodopsin changes shape
retinal
binocular cues also gives humans ______ _______
retinal disparity
incentive theory
reward, intangible or tangible, is presented after the occurrence of an action with intention of causing the behaviour to occur again. this causes a positive association and meaning toward a behaviour. focuses on conditioning/incentive to make a person happier. incentive theory argues that individuals are motivated to engage in behaviours that produce rewards or incentives ex doing well at work and getting promotion (tangible). or intangible - job satisfaction ex. incentive for football team is wining a game and getting recognition
a lot of proteins on the discs. one is ____ (on a cone the same protein is called photopsin), a multimeric protein with 7 discs, which contains a small molecule called retinal (11-cis retinal)
rhodopsin
rods contain ______, cones have similar protein ______
rhodopsin photopsin
clonus
rhythmic contractions of antagonist muscle. ex foot goes involuntarily up and down. cause is hyperreflexia, because if doctor pulls on foot activates muscle stretch reflex, so triggers antagonist muscles
all light from the nasal side of both eyes cross to the other side so left nasal info goes to ___ side and vice versa
right
light enters the pupil and goes to the retina, which contains ______ and _____
rods and cones
evolutionary approach (motivation)
role instincts play in motivation. what do humans do to survive? what is not learned and just instinct ex think about baby, cries, sleep, eat. basic instincts that all humans have
fMRI (functional magnetic resonance imaging)
same image from MRI but can look at which structures are active! neurons that are active require oxygen. measuring relative amounts of oxygenated vs deoxygenated blood in the brain - we can figure out what brain areas are being used for certain task. fMRI is more popular. MRI registers magnetic changes via radio waves and fMRI is a calculated composite of several MRI images registering the changes (shows activity as coloured areas over MRI). MRIs are slow but offer high resolution of soft tissue, such as the brain
norms are reinforced by sanctions --
sanctions are rewards/punishments for behaviours in accord with or against norms respectively positive sanction - a reward for conforming to norms negative sanction - a punishment for violating norms formal sanctions - officially recognized and enforced informal sanction - unofficially recognized and does not result in specific punishment
neural networking theory
sates that there are innate language mechanisms that can be activated by experiences
rote rehearsal
say the same thing over and over. least effective technique. simply repeating information. it requires the least amount of cognitive effort
spreading activation
says all ideas in your brain are connected together. pulling up one memory pulls up others as well
the dual coding hypothesis
says its easier to remember words associated with images than either one alone. can use the method of loci - imagine moving through a familiar place and in each place leaving a visual representation of topic to be remembered
psychoanalytic theory
says personality is shaped by childhood experiences person's unconscious thoughts/desires, feelings, and past memories (particularly experiences in childhood) personality has memories, beliefs, urges, drives and instincts that we are not always aware of that make up the unconscious. says childhood experiences and unconscious desires
behaviouralist theory
says personality is the result of learned behaviour patterns based on a person's environment - its deterministic, in that people begin as blank states and the environment completely determines their behaviour/personalities. do not take thoughts and feelings into account. environment -> behaviour focuses on observable and measurable behaviour, rather than mental/emotional - the psychoanalytic theory would be most opposite of this theory (focuses on mental behaviour)
cognitive economy principle
says that our brain is efficient. evidence: how long it takes people to verify certain statements. for example, it takes people little time to verify a chancy is a canary, more time to verify canary is a bird, and even more time to verify canary is an animal
sometimes info we receive is based on a _____ instead of reality
schema (mental blueprint containing common aspects of the world
negative reinforcement
taking something away to increase tendency behaviour will occur again
compulsive stimulation-seeking
seeks excitement or distraction through compulsive shopping, sex, gambling, risk taking, physical activity, novelty, etc
daily hassles
seemingly minor events/hassles of daily life. ex, long store lines, forgetting car keys, aggravating roommates, email spam. daily hassles often accompany low SES - inadequate income or employment for minorities daily hassles might include racism many consider (Mike Lazarus, connor mcdonald) the most important form of stress
we modify our cognitions traduce cognitive discomfort, we don't change our behaviour
selective exposure: would most likely refer to avoidance or reduce dissonance post decision dissonance often follows an impulsive purchase that is difficult to return when someone does something and there is minimal justification for them doing it, this creates more dissonance than if they can explain it through a significant rationale. the dissonance then acts to make them internally justify the action saying "i wanted to do it anyway because i like doing that sort of thing" change vs compliance - small rewards change cognitions, large rewards - just compliance minimum justification principle: when someone does something and there is minimal justification for them doing it, this creates more dissonance than if they can explain it through a significant rationale. can occur after buying something you didnt want to. need to introduce a new cognition to create cognitive dissonance - this is best done through action of the participant which affirms a second cognition (new information would NOT do this... as a cognition needs to be developed and internalized)
first theorist of the humanistic theory was abraham maslow, who formed hierarchy of needs. must first fulfill physiological needs of pyramid and work our way up, then safety, then love, self esteem, and finally self actualization
self actualization is rarely achieved, only 1% of people ever reach it. self aware, caring, wise, and interests are problem entered. they have a higher purpose that is focused on larger causes and less about basic aspects of life. they are striving to think of larger causes. average person seeks to self actualize but we don't achieve it
improve
semantic memories improved until around age 60. so older adults have better verbal skills. also crystallized IQ is improved (ability to use knowledge and experience, typically tested by analogy tests and reading comprehension). also better at emotional reasoning
cognitive improvements
semantic memory (improves until 60 years) (verbal skills) crystallized intelligence (use knowledge and experience) (using reading comprehension to test) emotional reasoning
VTA
sends dopamine to the amygdala (controls emotions), nucleus accumbent (NAcc, controls motor functions), prefrontal cortex (focus attention and planning) and hippocampus (part of the temporal lobe, involved in memory formation) NAcc, amygdala and hippocampus are part of the mesolithic pathway
proprioception
sense of balance/position
rods are 1000X more _______ to light than cones
sensitive
thalamus
sensory relay station, everything you hear/taste/etc. senses come through your nerves and end up in thalamus, which directs them to appropriate areas in cortex, and other areas of the brain. emotions contingent on senses. smell is only one that bypasses the thalamus - goes to areas closer to amygdala
detoxification (detox)
separating addict from the drug. sometimes require strong medications for strong addictions (have to break the addiction cycle). often have to address symptoms such as vomiting, nausea, pain, etc.
information support
sharing information with us or giving us advice. can come from family, friends, or even articles online
avoidance
signal is given before aversive situation. the behaviour is to avoid the situation, which results in continued avoidance because it is reinforced by the removal of the pain/undesirable stimuli.
compliance
situations where we do behaviour to get a reward or avoid punishment. tendency to go along with behaviour without questioning why. compliance goes away once rewards/punishments removed
both nociception and thermoception are _____
slow

sound, wernicke's area
1) social stigma
social stigma can be fuelled or associated with several other key concepts: stereotypes, prejudices, discrimination. relationship/overlap between stigma and these is unclear and is variable depending on source - derive from symbolic interactionist on source -calls attention to how certain individuals or groups face social disapproval. often, the social disapproval is associated with a behaviour, identity, or other attribute that is considered deviant by others" associated with an attribute that is devalued
symbolic interactionism
society is a product of everyday interactions of individuals. looking at how people behave in normal everyday situations and helps us to better understand and define deviance
insight learning
solve a problem using past skills, the aha moment is insight learning
parietal lobe
somatosensory cortex (touch/pressure/pain), spatial manipulation (orient in 3D) somatosensory cortex: motor cortex (frontal) + somatosensory cortex (parietal). somatosensory cortex - involved in receiving sensory signals from the skin
positive punishment
something is added to decrease tendency something will occur again
positive reinforcement
something is being added to increase tendency of behaviour
negative punishment
something taken away in effort to decrease tendency it will occur again
proactive interference
something you learned in past impairs learning in future. earlier information interferes with later information.
tend and befriend response
sometimes better response to stress is to have support systems. oxytocin is important for this - peer bonding and moderates the stress response. oxytocin is strongly linked to estrogen (a major sex hormone in women), so why this response is stronger in women) so why this response is stronger in women
interactionist approach
sometimes called social interactionist approach. believe biological and social factors have to interact in order for children to learn language. children's desire to communicate with others - such as adults in their life, makes them motivated to learn language. associated with vygotsky
spacing
spreading out study sessions overtime in sorter periods rather than cramming them into one study session (spacing effect)
Sensorimotor stage
stage 1, 0-2 years old. (sensory = senses - children gather information about the world via sight, smell, taste, hearing, touch, etc + motor - active, as you develop how to use senses you learn t move your body around). main task.awareness develops is object permanence: objects exist even if they can't see them..
preoperational stage
stage 2. 2-7 years old. (operations = mental operations like imagining thins). when children are going to develop/engage in pretend play. start to use symbols to represent things. words symbolize objects and children start understanding symbols. also, very egocentric - only concerned about themselves, no empathy (they don't understand that other people have a different point of view than they do). associated with the inability to understand the perspective of others
concrete operational
stage 3, 7-11 years old. concrete operational (operational - mental operations". Learn idea of conservation. begin to learn empathy, begin reasoning of math skills. the concrete operation stage describes children who are able to grasp concrete (real) events logically, conversion, and reversibility (refers to the ability to recognize that numbers or objects can be changed and returned to their original condition
norms
standards for what behaviours, set by groups of individuals, are acceptable and which are not. rules that dictate how person should behave around certain group of people - and are defined by that group and usually guided by some sort of moral standard or ethical value is easily understood and internalized by all members of the group. provide structure and standards of how people can behave
game stage
start to understand attitudes/beliefs/behaviour of "generalized other" (society as a whole). with this comes whole new understanding of society. children start to realize that people perform in ways not only on what they personally believe but what also in the ways society more broadly expects of them and they understand that people can take on multiple roles (people can be more than just moms, doctors, or teachers- they can be multiple things at once). also realize others have opinions about them and those perceptions others have are based on how they act and what they say. they begin to be influenced by these perceptions and are concerned by reactions of others to what they do. but don't care about reactions of everyone, only significant others (people with important relationships to individual ex parents/teachers/close peers) this stage led to I and Me
differential association
states that deviance is a learned behaviour that results from continuous exposure to others whose violate norms and laws - learn from observation of others. rejects norms/values and believes new behaviour as norm - relationships a person forms are very important - if strong relationship to someone deviant, the person is more likely to learn deviance than someone not. known as monkey see monkey do
linguistic universals theory
states that there are characteristics that remain consistent across all languages of different cultures
physiological components of emotion
when surprised, heart rate might increase, muscles tense, temperature increases
mechanoreceptor
stimuli: mechanical stress pressure changes (baroreceptors) sound waves gravity Location: skin blood vessels ear - tend to have large diameter and thick myelin sheath; therefore they conduct fast. noci and thermo have small and have thin myelin or no myelin -> slow
richard lazarus
stress arises less from physical events but more from the assessment/interpretation of those stresses/events. appraisal. this is appraisal theory of stress. there are 2 stages of the cognitive stages - the primary appraisal and secondary appraisal
substantial nigra also projects to area of basal ganglia called the _____, and loss of dopamine neurons protecting from substantial nigra tot he striatum causes most of motor abnormalities of parkinson's
striatum
skinner
strict behaviourist, associated with concept of operant conditioning. uses rewards/punishment to increase/decrease behaviour, respectively
broca
studied a patient with the loss of speech (but not other mental disorder). this patient (along with others who he studied) had a specific part of the frontal lobe that was damaged (broca conducted autopsies to figure this out). the brain region was involved in speech production. this area is called the broca's area. broca's aphasia: loss of ability to express speech - in this method you have to wait till someone dies to figure out what brain area it damaged - in this time, a patient can have more brain injuries that occur - patient can outlive scientist - patient could move away. family could refuse autopsy/access to brain and body
ethnography
study of particular people and places. it is more of an approach than a single research method in that it generally combines several research methods including interviews, observation, and physical trace measures. good ethnography truly captures a sense of the place and peoples studied
subcortical cerebrum
subcortical cerebral nuclei that are located deep part of the cerebrum internal capsule - contains many important pathways, including the corticospinal tract corpus collosum - connects right and left cerebral hemispheres basal ganglia - major role in motor functions, dnt have UMNs but help motor areas to perform proper movements. also, cognition + emotion thalamus - sensory functions, because all senses have pathways that travel to the thalamus. also higher functions of brain such as cognition and emotion hypothalamus - controls the pituitary gland, the master gland that controls all other glands in the body
stress reaction
subsequent physical and emotional response
panic disorders
sudden burst of sheer panic and intense fear panic attacks - sudden, intense, might be in response to any stimuli - heart palpitations or sweating or chest pain or shortness of breath panic attacks are in response to situations that typically don't warrant that level of stress - there are situations where a high level of panicking is appropriate ex if you are being attacked by someone, someone breaks into your house there are physical symptoms as well
empathy altruism hypothesis
suggests some people are altruistic due to empathy high empathy = high in altruistic behaviours. those who score higher on empathy are more altruistic
triarchic theory of intelligence (robert sternberg)
summary 3 independent intelligences based on real world success: analytical (problem solving ability), creative intelligence and practical intelligence strength/evidence reliable, easy to study by research problems research shows that scores of all intelligences vary together. are these 3 sides of the same coin?
theory of multiple intelligence (howard gardner)
summary explained ideas of what can be included in intelligence gardner divided into 7 then 9 independent intelligence (they don't depend on each other and hence intelligence in 1 area does not predict intelligence in another) logical mathematical intelligence, verbal linguistic, spatial visual, bodily kinaesthetic, interpersonal, interpersonal, musical. later added 2: naturalist and existential intelligence strength/evidence: you can have different strengths independently. intelligence is more than just "book smarts" problems: no way to test this theory (not supported by research) intelligence vs. talents/abilities (but maybe this is just a labelling)
MEG (magnetoencephalggram)
superconducting quantum interface device - better resolution than EEG, but rather because requires a large machine and special room to shield it. records the magnetic fields produced by electric currents in the brain. measured by using SQUIDS
K complexes
suppress cortical arousal and keep you asleep. also help sleep based memory consolidation (some memories are transferred to long term memory during sleep, particularly declarative/explicit memories). even though they occur naturally, you can also make them occur by gently touching someone sleeping. "that touch was not threatening, stay asleep brain"
tissue removal
surgical removal, surgical aspiration (sucking out brain tissue), or severing the nerve with a scalpel (this allows for a destroying of the brain tissue in place... less invasive)

mass media
television, internet, radio, books, magazines. when you are young you learn things through mass media that parents would not approve of. today, children are exposed to a lot of content intended for mature audiences - violent tv shows. enforces gender and other stereotypes ex children books are another agent of socialization
the central executive
tells the visuospatial sketchpad + phonological loop to coordinate. the central executive supervises the cognitive process of memory
evolutionary game theory
tells us those with best fit to environment will survive and pass on to offspring, and those genes will become more common in successive generations reproduction and environment are central to evolutionary game theory -reproduction important to game theory because its can't happen in isolation and it needs to involve others environment - how organism fits in with social and physical environment. work with router organisms to find food, raise young, deal with predators
touch

temporal lobe (sound processing), understand.
unconscious mind
the bottom part of the iceberg is the larger part of the mind (most of the mind is unconscious just like most of an iceberg is beneath water). consists of primitive, instinctual wishes and information that cannot be accessed - not to be confused with subconscious mind/precocious mind: consists of information that become accessible once you direct your attention to it (memory recall for example)
social loafing
tendency to put forth less effort in group task if the individual contributions aren't evaluated. social loafing is the tendency for individuals to put forth less effort when part of a group
generalization
tendency/ability of a stimulus similar to conditioned stimulus to elicit a conditioned response, and more similar the stimulus is to original conditioned stimulus - the greater the conditioned response - has an adaptive value - generalization allows us to make appropriate response to similar stimulus. ex meeting someone new who smiles, reminds us of other smiles (both enjoy feelings of joy)
stressors like threats and dangers trigger our fight or flight system
the NS (sympathetic NS) (part of the ANS) and the endocrine response sympathetic response: fight or flight the triggers our "get out of danger mode" see increased heart rate and increased respiration (more energy + oxygen in blood + more CO2 expelled), increased peripheral vasoconstriction (push more blood to our core area/vital organs that it is hard to live without. we take blood out of the extremities like our legs/arms which are less essential for our survival), and turn off digestion/immune/ovulation (less crucial)
dissociation
the ability of the mind to separate and compartmentalize thoughts, memories, and emotions. this is often associated with post traumatic stress syndrome
cocktail part effect
the ability to concentrate on one voice amongst a crowd. or when someone calls your name (endogenous cue: meaning of name draws attention)
self control
the ability to control our impulses and delay gratification. influences how we behave
the specialized part of the olfactory epithelium in animals -
the accessory olfactory epithelium
covert orienting
the act of bringing the spotlight of your attention of an object or event without body or eye movement

the adrenal medulla release catecholamines (epinephrine/adrenaline and norepinephrine/noradrenaline) catecholamine's are tyrosine derivatives. developed from ectoderm. the adrenal cortex release glucocorticoid (cortisol) - steroid hormone redistributes glucose energy in body suppressing immune system. developed by endoderm. acronym: COTisol is released by CORTex play a role in development of muscles/bones
Limbic system is involved in emotion:
the amygdala is conductor of emotional experiences, communicating between the hypothalamus (physiological) and prefrontal cortex (behaviour). Amygdala pays key role in fear/aggression
what connects the observable (behavioural) to mental approach (psychoanalytic) approach?
the cognitive theory, a bridge between classic behaviourism and other theories like psychoanalytic. because cognitive theory treats thinking as a behaviour, and has a lot in common with behaviour theory (albert bandura comb)
contextual effects
the context in which stimuli are presented and the processes of perceptual organization contribute to how people perceive those stimuli (and also that the context can establish the way in which stimuli are organized)
social potency trait
the degree to which a person assumes leadership roles and mastery of roles in social situations. common in twins reared separately
transmission
the electrical activation of one neuron by another neuron
source characteristics
the environment around the message and the speaker's background. what is their level of expertise of speakers around us - do they seem knowledgeable, trustworthy, and is information credible or not. where does the information come from - internet poll, street poll, pr a psych journal. physical environment, venue of event (campus or a bar)
joint attention
the focusing of attention on an object by 2 separate individuals
cultural component of bias
the fundamental attribution error occurs more in individualistic societies who place an emphasis on individual achievement

reciprocal determinism
the interaction between a person's behaviours, personal factors (motivation/cognition) and environment are all determined by one another
superego
the internalization of cultural ideals and parental sanctions. "morals" interjection/internalization. the superego inhibits sexual and aggressive impulses, and tries to replace reality with morality, striving for perfection. the superego has subsystems: the conscious - what you should not be "wrong" - the ego ideal - what you should/want to be "right" - if you think about this theory, its the classic angel(super ego) and devil (id) on the shoulder telling you what to do. it is up to you to decide (ego) but if your conscious self (ego) is weak, you';; end up having one of the other 2 take over - leading to an imbalance. this is why psychoanalytic therapy focuses on raising the intrapsychic conflicts to the conscious level
law of past experiences
the law of past experience implies that under some circumstances, visual stimuli are categorized according to past experience. if 2 objects tend to be observed within close proximity, or small temporal intervals, the objects are more likely to be perceived together. for example, the english language contains 26 letters that are grouped to form words using a set of rules. if an individual reads an english word they have never seen, they use the law of past experience to interpret the letters "L" and "I" as 2 letters beside each other, rather than using the law of closure to combine the letters and interpret the object as an uppercase U
abnormalities of LMN can cause:
the lower motor neuron signs (LMN signs) which can happen in addition to weakness (abnormalities in the motor unit) signs: atrophy of skeletal muscle, fasciculations (involuntary twitches of skeletal muscle), hypotonia (decrease in tone of skeletal muscle - how much muscle is contracted when person is relaxed), hyporeflexia (decreased muscle stretch reflex)
Mead developed the idea of social behaviourism:
the mind and self emerge through the process of communicating with others (beginning of symbolic interactionism)
symmetry
the mind perceives objects as being symmetrical and forming around a centre point
absolute threshold of sensation
the minimum intensity of a stimulus needed to detect a particular stimulus 50% of the time
how does a molecule bind to a receptor and cause an AP?
the molecule binds to the GPCR receptor on odour molecule -? GPCR on olfactory epithelia -> G protein dissociates and causes a cascade of events inside the cell -> G protein binds to ion channel which allows cells outside the cell to come inside -> opens and triggers an AP -> goes to cribriform plate -> glomerulus -> activate mitral/tufted cell -> synapse to brain
benzodiazepines
the most commonly prescribed suppressant. subscribed for same things as barbiturates - sleep aids (to treat insomnia) or anti-anxiety or seizures (anticonvulsant) - enhance your brains response to GABA. they open up GABA-actovated chloride channels in your neurons, and make neurons more (-) charged 3 types: short, intermediate, and long acting. short and intermediate are usually for sleep, while long acting is for anxiety -zelam, -zolam benzodiazepines and alcohol bind to a site on the GABA(A) receptor complex that regulates the sensitivity of the receptor complex
processing
the neural transformation of multiple neural signals into a perception
"in" group
the one we are connected with. US. stronger interactions with the in the in-group than those in the out-group. interactions are more common and more influential as well within in-group

meaning-focused coping
the person concentrates on deriving meaning from the stressful experience
cultural relativism
the practice of assessing a culture by its own standards rather than viewing it through the lends of ones own culture. judge and understand another culture from within their culture
stress
the process by which we appraise and cope with the environmental threads and challenges. it encompasses both the stressor and the stress reaction
people perform the best when they are moderately aroused -- the Yerkes-Dodson Law
the relationship between long term memory and fear follows a Yerkes-Dodson curve this means that extreme emotional responses usually impact memory negatively moderate emotions, like mild fear, are associated with optimal memory recall
bureaucracy
the rules, structures, and rankings that guide organizations (does not mean something negative, lines, or red tape)
foreign
the search for food in animal's environment. can't survive or reproduce without it
stressful/negative
the stressor is actually threatening. ex rabbit having to run away from the dog
false alarm
the subject perceived a signal when there was none present
site
the subject responded affirmative when a signal was present
in brainstem (parkinson's)
the substantia nigra (means black substance, usually darker than surrounding black tissue in normal patients) is less dark or not dark at all in PD patients. suggests only one type of neuron is involved. these cells/neurons lost are ONLY dopaminergic neurons (NT dopamine releasing). motor abnormalities related to loss of dopaminergic neurons lost at the substantia nigra - dopaminergic neurons in other areas are lost as well - substantial nigra is one part of the basal ganglia, if we section a brain from top to bottom and we look at deep area of cerebrum, near the centre there will be a collection of structures called the basal ganglia. one part of this is the substantial nigra. basal ganglia is located at base of forebrain. - basal ganglia plays a role in motor functions and some mental functions. receives info from many places in NS, particularly the outermost layer of the cerebrum (cerebral cortex) - basal ganglia processes that info and sends it back to areas of cerebral cortex to influence areas of activity such as motor cortex
companionship support
the type that gives someone sense of social belonging. companionship while you engage in an activity
brain uses basilar tuning
there are varying hair cells in cochlea and allows brain to distinguish between high and low frequency sounds. hair cells at base (start of cochlea) of cochlea are activated by high frequency sounds, and those at apex (end of cochlea) by low frequency sounds.
neonatal reflexes
these disappear as a baby ages. some are survival reflexes (help us live) while others might be evolutionary holdovers or precursors. help doctors assess if something is not developing correctly rooting reflex: check stroking = baby turns head. allows for orientation to motors nipple/bottle. disappears in few weeks of life - then baby turns head voluntarily babinski reflex: how baby will turn/unturn toes when bottom of the foot. disappears before 12 months (fans toes outwards) mono reflex: startle reaction. fan out arms then back. disappears in 5-6 months age tonic neck reflex (aka fencing posture) - how when a baby's head is turned, the arm on that side straightens while the arm on the side that is opposite bends. disappears at 6 months palmer grasp reflex: children close their hands on anything that comes in their palm. disappears at 3-4 months, then child grasps things voluntarily sucking reflex: how a baby will suck on any object that is placed in its months. disappears 3-4 months stepping reflex: hold an infant upright and their feet touch a flat surface, they will start to step as if they are trying to walk. disappears in first 2 months swimming reflex: infants in water move legs/arms in a swimming motion. involuntarily hold breaths. allows a small infant to swim/float for a short period of time. disappears at 6 months
relative height
things are perceived to be farther away than those that are lower
if you go through period of not having the drug, you experience withdrawal symptoms
things less strong as cocaine won't give you as strong an effect, so dopamine levels decrease and you feel depressed, highly anxious, etc will do whatever it takes to get high once you've built your tolerance, need drug to feel normal again, not euphoric -- addicted
personal identity
things unique to each person like personality traits
self referencing
think about new info and how it relates to you personally.
PAW usually lasts for 2 years
this is one of the most important things you need to remember. if you are up for the challenge you can get through this. if you think PAW will only last a few months you will get caught off guard. -- disappointment can trigger relapse
MRI (magnetic resonance imaging)
this method uses radio waves and they are exposed to a magnetic field. the radio waves are then dded to the magnetic field and disrupts orientation of atoms. as atoms move back to alignment with magnetic field they release signals and those are used to create image. this also doesn't tell us anything about brain function either
deindividuation
those in group are more likely to act inappropriately because crowd conceals person's identity. good example is behaviour of some on black friday. prince of large group there is violence (shoppers trample employees, shot shoppers, stolen goods from stores). presence of large group decreases their inhibition/guilt, hence increases antisocial/deviant behaviour
secondary reinforcers
those learned to be reinforcers, such as previously neutral stimuli. requires a pairing or association with a primary reinforcer for it to have value
cognitive (rational and decision making ability)
thought processes drive behaviour. ex light bulb going off in ones head
evolutionary biology (dreams)
threat simulation, to prepare for real world problem solving no purpose
stressor
threatening/challenging event
fixed interval
time is constant. pay won't change if you see 1 or 100. response rate is slower
conscious mind
top of iceberg is the conscious part of the ind (small, tip of the iceberg). these are the mental functions you are aware of
when light hits, comes through pupil and hit the retinal, then it hits rods, some of the light hits rhodopsin (which contains the retina) and causes the retinal change conformation from bent to straight conformation (11-______ ______)
trans retinal
when the rhodopsin changes shape, ____ breaks from rhodopsin and alpha subunit binds to another disk protein called phosphodiesterase (PDE)
transducin
adolescence:
transition period between childhood and adulthood begins with puberty: a 2 year long sexual maturation (end of which you can reproduce). start time males 13 yo, females 11 yo. can start earlier/later depending on individual. puberty milestones/landmarks: males (first ejaculation - 14 yo), females (first menstrual cycle 12-13 yo)
retrieval
trying to remember/call up a memory of something you learned before. successful retrieval depends on being able to use cues around you and to recognize the association between cues present at encoding and cues present at retrieval. best types of cues are the associations that form when you are actually encoding
personality
unlike psychological characteristics/abnormalities, it is believed to be constant over a person's lifetime - is our personality hard wired and persistent as we age? what about our gender identity? or intelligence?
availability heuristic
using examples that come to mind. helpful, but our easily memorable experiences don't match real state of the world. decision making heuristic where choices are based on quick, easily accessible examples
source monitoring can be improved by
using more retrieval cues discovering and noting relations and extended reasoning
sclera
usually absorbs by the time the light gets to this. the whites of the eye, thick fibrous tissue that covers posterior (5/6th) of the eyeball (cornea covers the anterior 1/6). attachment point for muscles. extra layer of protection and structure of eyeball. lined with conjunctiva
hypnotism
usually involves getting person to relax and focus on breathing, and they become more susceptible to suggestion in this state - but only if they want to. more alpha waves in this stage - an awake but relaxed state
aversive conditions
usually used to stop a particular behaviour. the process involves paring a habit a person wishes to break with an unpleasant stimulus such as electric shock or nausea.
heritability
variability of traits can be attributed to differences in genes percentage of variation of traits due to genes heritability estimates define the amount of variance that can be attributed to genes in specific subgroups of individuals
cognitive
vary person to person, they're mental assessments that can include appraisal of what is happening, thoughts and expectations about the situation. cognitive experiences result from emotions, and can cause emotions. ex someone might enjoy surprise party because of your previous cognition, or someone might hate surprise party
phonological loop
verbal info (any words, numbers in both iconic and echoic memory) is processed. ex repeating a phone # to yourself. the phonological store is believed that the phonological store capacity is around 2 seconds
authoritarian parenting
very strict, break will of child. punishment
negative emotions evoke more activity on right side
videos of negative emotions = right hemisphere increased activity on EEG. more activity on right more timid, fearful, depressed had more activity in right isolative
social cognitive theory
view behaviours as being influenced by people's traits/cognition and their social context. talking about interactions between individual and situation they are in cognition -> environment -> behaviour (the order can change as well)
defence mechanism
ways to protect ourselves - a psychological shield against anxiety or discomfort of unconscious psychological processes. a way to protect ourselves when we have to deal with unconscious wants, feelings, desires, and impulses classified into 4 categories
hans eysenck
we all possess all traits which express to different degrees. (allport said we have diff unique subsets, while eysenck says we all have them but just express them in different degrees - eysenck says we have 3 major dimensions of personality, which encompasses all traits we all possess, but the degrees to which we individually express them are different. we all express varying degrees of neuroticism and extraversion, but we all don't necessarily have psychoticism. these 3 are: pyshcoticism: degree to which reality is distorted extraversion (vs introversion) degree of sociability neuroticism: emotional stability - we do not all necessarily have pyschoticism
out group derogation
we are super friendly to our in group, but not friendly to our group - we discriminate. happens if we feel that the out group in threatening to or undermine in group's success
actor observer bias
we are victims of, but others are wilful actors. (same thing as saying; circumstance (we attribute out personal behaviour but others behaviour of internal factors)
in attentional blindness aka perceptual blindness
we aren't aware of things not in our visual field when our attention is directed elsewhere in that field. "miss something right in front of you"
ideal self
we can't live up to that is bounded by conditions
sociocultural factors
we eat for different occasions, time, desire, appeal, availability
in group favouritism
we favour/friendly to people in our own group, but those in out-grup we are neutral - we don't give them favours we do to our in group
chunking
we group information we are getting into meaningful categories we already know to ease memorization
foot in the door phenomenon
we have a tendency to agree to small actions first. eventually over time comply with much larger actions basic concept of how people are brainwashed too. door is eventually pushed completely open over time society behaviours strongly feed into your attitude
resource model of attention
we have limited resources in attention, resources that are easily overtasked if we try to pay attention to multiple things at once. - both models say something about our ability to multitask - not very good at it.
roles
we have many different roles that define what we do and who we are. we adopt social norms - the accepted standards of behaviour of a social group, use it to guide behaviours (what behaviour is appropriate). norms provide order in society and we use them to conform to expectations of that role/expectations of others. we respond to their approval when we play our roles well, and we get disapproval when we play roles badly. expect people to behave in way that fits that role, and have them fit the role even more when roles are stereotyped
Me
what we learn through interactions with others. how individual believes generalized other perceives us, the social self, and learned through interactions with others. socialized and conforming aspect of self - way to remember: the me, the conforming, socialized person who tries to not do any dick moves. societal views ex me thinks about people go from high school to college in US
ideal self
what we wish/aspire to be
important agents of socialization
whats used to transmit (pass around) culture, values, beliefs about acceptable behaviours, and beliefs. agents include people, organizations, and institutions that help us learn about our social world
extinction
when a CS does not felicity a CR anymore
relapse
when a patient can slip and go back. depends on environmental triggers and drug they were addicted to. more addictive substances with the drug makes relapse more likely as well. this is why its hard for people to stay clean
anxious avoidance
when a person avoids anxiety provoking situations by all means. this is the most common strategy
PTSD
when a person has lingering memories and nightmares about a past event that it impacted them in daily life (haunting/bad memories/repeated nightmares_ includes physical symptoms like insomnia have a trigger that leads to the disorder described as PTSD if symptoms persist for over 4 weeks after an event TRAUMA traumatic event re-experience avoidance unable to function month or more symptoms arousal increased - repressed memories/memory
obstructive sleep apnea
when airways are obstructed. soft tissues around our neck can relax at night and potentially cause obstruction of airflow for a short period of time. gets worse as people get older - at nighttime, this causes snoring or gasping or pauses in breathing at daytime, people are tired/sleepy and unrefreshed - diagnosed by: sleep study (a polysomnopgrapy) and looking for 15+ apneas/hour (apnea = lack of airflow)
extinctive burst
when an animal no longer receives regular reinforcement, its original behaviour will sometimes spike (meaning increase dramatically) - this is known as an extinction burst
Bipolar I disorder
when hypomania becomes manic with or without major depressive disorder an individual diagnosed with bipolar II has never had a manic episode although it is possible for an individual diagnosed with bipolar I to never experience hypomania, it is extremely unlikely
2) self stigma
when individual can internalize all the negative stereotypes, prejudices, and discriminatory experiences they've had, and may being to feel rejected by society, avoid interacting with society
feature detection
when looking at an object, you need to break it down into its component features to make sense of what you are looking at. there are 3 things to consider when looking at any object: colour, form, motion
front stage
when people are in a social setting. "putting on a front and acting for an audience"
addition
when searching for coping mechanisms there are good options and bad options. these terrible options lead to addiction often. ex alcohol, tobacco, etc - impairment to frontal cortex (reasoning), so impaired judgement can increase likelihood of inappropriate coping mechanisms
fertilization
when sperm and egg meet. steps of fertilization are: sperm binding -> acrosome reaction -> cortical reaction -> genetic transfer
hypoventilation disorder
when we are not able to ventilate our lungs fully and remove all CO2. results in a buildup of CO2, and a decrease in O2. can occur due to medications that repress respiratory functions (narcotic pain killers such as opioids) or if there is a problem with the lungs or chest wall. a common occurrence is due to obesity - high CO2 can cause right sided heart failure - low CO2 effects all organs/tissues of bodies/ cognitive impairment, heart problems, (arrhythmias) and polycythemia (elevated RBC)
false consensus
when we assume everyone else agrees with what we do, even if they do not
projection bias
when we assume other share the same beliefs we do
reality principle
when we become mature, you need to sacrifice short term reward and replace it with long term gratification. not always going to get what you want and the outside world might tolerate your behaviour. you have to place by the rules of the real world and might have to compromise "play your role in the real world"
informational social influence
when we conform because we feel others are more knowledgeable than us, because we think they know something we don't
role strain
when you can't carry out all obligations of a status, tensions within one status. causes individual to be pulled many directions by one status
withdrawal
when you stop after using for prolonged time. we get withdrawal symptoms. can become sick or ill, or it can be fatal 2 stages: acute, post acute
blind spot
where optic nerve connects to retina -- no cones or rods
backstage
where you work on impression management

white grey
circadian rythms
why you get sleepy in afternoon. regular body rhythms in a 24 hour period. controlled by melatonin produced in pineal gland
CAT (computerized axial tomography)
x rays to create image of the brain (tutor/abnormal swelling/bleeding... but it can't tell us anything about what areas of the brain are active in a given time) - CT scans are a computerized composite of X ray images that are slightly lower resolution than MRI and are not as good for soft tissue but are faster than MRIs. sometimes CT scans are combined with a radioactive dye (like a PET scan) to show structure and activity imposed in one image
selective attention:
you are selecting one at a time. its like a flashlight on your attention - you can move it around at any spot. at any given moment, illuminating attention while being presented with masking or interfering stimuli
learned helplessness
you learn from having control ripped out of your hands that you don't have control, so lose ability to identify coping mechanisms because taking less control out of your life.cycle continues downward into major depression
alertness
you're awake, aware of who you are, whats going on in the environment, focus your attention, engage in conformation, code info to your memory
publicly conform
you're outwardly changing but inside u maintain core beliefs. u only outwardly agree with the group
sleep stages:
your brain goes through distinct brain patterns during sleep. 4 main stages that occur in 90 min cycles
state dependent
your state at the moment you encode. when you are in a certain mood when you encode you can then remember it when you are in the same mood
blastocyst stage
zona pellucida is disintegrating while the endometrium lining its proliferating (forming valleys called crypt). apposition is when the blastocyst attached to the endometrium - outer trophoblasts divide into endometrium (adhesion). endometrium is also dividing endometrium has blood vessels that are getting bigger. trophoblasts are getting larger and they start to fuse (syncitiotrophoblast) + cytotrophoblast (the ones that used to be trophoblast) synciotrophoblasts form villi and the endometrium is growing (which is uterine blood) synciotrophoblasts that formed vill form blood vessels - which are close contact to uterine blood. lines inside of uterine cavity - placenta
embryogenesis
zygote after fertilization has occurred then splitting occurs in zona pellucida (which still exists, in the previous stem the zona pellucida hardens to prevent sperm binding - now its back) cleavage happens (splitting without growth): splitting from 1 cell -> 2 cell -> 4 cell -> 8 cell -> 16 cells -> morula: 32 cells. the cells become tighter (cells get closer together and the outside become different). differentiation is occurring. the outside is trophoblast and the inside is an embryo blast blastulation occurs
