Explain the control of thyroid hormone by the hypothalamus and pituitary.
Decreased levels of thyroid hormone and certain stimuli cause the hypothalamus to secrete thyrotropin-releasing hormone (TRH), which causes release of thyroid-stimulating hormone (TSH) from the anterior pituitary. TSH reaches the thyroid gland and causes release of thyroid hormone (TH) from a stored precursor. This interactive sequence is referred to as the hypothalamic-pituitary-thyroid axis. Thyroid hormone increases metabolism with a subsequent increase in body temperature. To support the higher metabolic rate additional glucose and fatty acids are released into the blood, heart rate and force of contraction are increased, and breathing rate is increased.

Contingency "schedule"
If a consequence does not contingently (reliably, or consistently) follow the target response, its effectiveness upon the response is reduced. But if a consequence follows the response consistently after successive instances, its ability to modify the response is increased. The schedule of reinforcement, when consistent, leads to faster learning. When the schedule is variable the learning is slower.

If you choose to drink alcohol, drink in moderation. One drink refers to one (12 oz.) bottle of beer, one (5 oz.) glass of wine, or one (1.5 oz.) of 80-proof liquor. Each of these has about 0.6 oz of ethyl alcohol. Limit your alcohol consumption to no more than 2 drinks per day for males or 1 drink per day for females.
How would "inappropriate encoding" affect whether or not we forget something (e.g. doing structural encoding when we'll later be asked about the meaning of things)?
If you use a lower level of processing than necessary, you will be unable to recall things that require a higher level of processing
-fatigue, decreased concentration, sleep disorders -jet lag: biological clocks keep usual time while official clock changes -rotating work shifts = disrupted rhythm
Ignoring Circadian Rhythms
-ignoring rhythms is becoming more common in the USA -average night of sleep 100 years ago was 10hrs; now is 6.9 hours
Ignoring Circadian Rhythms Continued
Describe the shaping procedure, and explain how it can increase our understanding of what animals and babies can discriminate
In shaping, we use reinforcers to guide a person's or an animal's behavior toward a desired goal. Building on existing behaviors, we reward successive approximations to some desired behavior. Because nonverbal animals and babies can respond only to what they perceive, their reactions demonstrate which events they can discriminate.
Stage 2
In stage 2, eye movement stops and brain waves become slower with only an occasional burst of rapid brain waves. When a person enters stage 3
What are the different reasons why we might forget information?
Ineffective encoding (pseudoforgetting), inappropriate encoding, decay, interference: proactive (previously learned information interferes with you learning new information) & retroactive (newly-learned information interferes with you remembering previous information), retrieval failure: misinformation effect & source monitoring error, motivated forgetting (aka repressed memories): your mind—unconsciously—represses negative events in your unconscious
What is pseudoforgetting and what causes it?
Ineffective encoding, never really learning it in the first place; causes: lack of attention / being distracted (you can't actually multi-task)
Experimental method

Explain how latent learning and the effect of external rewards demonstrate that cognitive processing is an important part of learning
Latent learning, as shown in rats' learning of cognitive maps or children's delayed imitation of others' behavior, indicates that we can learn from experience, without apparent reinforcement. AN external reward's ability to undermine our interest and pleasure in an activity weakens the idea that behaviors that are rewarded will increase in frequency

No, chicken pox for the mother can cause severe birth defects in the fetus
Is the adolescent period a period of turmoil? Why do some say it is? What do the rest of the researchers say?
Not really; "in flux" as they are in various statuses of deciding what person they want to become, relations between adolescents and their parents. Maybe because there is an increased frequency of arguments (about non-serious issues like the type of clothes one is wearing); tend to bother the parents, more so than the adolescent.

Compare positive and negative reinforcement, and give one example each of a primary reinforcer, a conditioned reinforcer, an immediate reinforcer, and a delayed reinforcer
Positive reinforcement adds something desirable to increase the frequency of a behavior. Negative reinforcement removes something undesirable to increase the frequency of a behavior. Primary reinforcers are innately satisfying-no learning is required. Conditioned reinforcers are satisfying because we have learned to associate them with more basic rewards. Immediate reinforcers offer immediate payback; delayed reinforcers require the ability to delay gratification.
PET "Positron Emission Tomography"
Positron Emission Tomography (PET) uses trace amounts of short-lived radioactive material to map functional processes in the brain. When the material undergoes radioactive decay a positron is emitted, which can be picked up be the detector. Areas of high radioactivity are associated with brain activity.

Describe the homeostatic system involving growth hormone.
Release of GH from the anterior pituitary is controlled by the release of growth hormone-releasing hormone (GHRH) and growth hormone-inhibiting hormone (GHIH) from the hypothalamus. Growth hormone stimulates the release of insulin-like growth factor (IGF) (somatomedin) from the liver; both GH and IGF stimulate target cells (especially muscle) to increase protein synthesis, mitosis, and cell differentiation; liver to increase both glycogenolysis and gluconeogenesis; and adipose connective tissue to increase lipolysis.

What is a correlation and why can't we make causal conclusions from correlations?
So, when a cause results in an effect, that's a causation. In other words, correlation between two events or variables simply indicates that a relationship exists, whereas causation is more specific and says that one event actually causes the other. One can't make solid conclusions about the two because there is no solid evidence that could support that claim.
One of the most famous behaviorists who suggested that free will was an illusion:
Skinner
Burrhus Frederic (B.F.) Skinner (1904 - 1990)
Skinner is regarded as the father of Operant Conditioning, but his work was based on Thorndike's (1905) law of effect. OC, a.k.a. instrumental conditioning. In operant conditioning, learning refers to changes in behavior as a result of experiences that occur after a response. Skinner believed in the existence of the mind but he specified that in order for psychology to be a real science, it cannot study anything that's not directly observable.

Patent content
According to Freud, dreams have two types of content, each of which contains different meanings to the dreams. One of these type of content is latent content, which is the underlying, more hidden, but true meaning of a dream (as opposed to the manifest content). Freud believed that the latent content was somehow censored by the subconscious which was a way to protect us from the real meanings of the dreams. This was necessary because the dream content may be difficult for people to deal with, so people disguise the real meaning. However, Freud believed that when people were in conflict, if he could uncover or get to the latent content, then he could identify the person's problem and resolve their conflict.

Discuss the strengths and weaknesses of continuous and partial reinforcement schedules, and identify four schedules of partial reinforcement
In continuous reinforcement, learning is rapid, but so is extinction if rewards cease. Continuous reinforcement is preferable until a behavior is learned. In partial reinforcement, initial learning is slower, but the behavior is much more resistant to extinction. Reinforcement schedules may vary according to the number of responses rewarded or the time gap between responses. Fixed-ratio schedules offer rewards after a set number of responses; variable-ratio schedules. after an unpredictable number. Fixed-interval schedules offer rewards after set time periods; variable-interval schedules, after unpredictable time periods.

fMRI "Functional magnetic resonance imaging"
Functional magnetic resonance imaging (fMRI) technique for measuring brain activity by detecting the changes in blood oxygenation and flow that occur in response to neural activity - when a brain area is more active it consumes more oxygen and to meet this increased demand blood flow increases to the active area. fMRI can be used to produce activation maps showing which parts of the brain are involved in a particular mental process.
Disagrees with structuralism, Mental adaptions occur for survival, a movement in psychology which was inspired by Darwin's work:

Why we Sleep
-Eliminate waste from muscles -Repair cells -Replenishing energy -Strengthens immune system -Improves memory -After 4 days you start hallucinating and can die -Sleep appears to provide a timeout period, so that the body can eliminate waste products from muscles, repair cells, conserve or replenish energy stores, strengthen the immune system, and recover abilities lost during the day -When we do not get enough sleep, our bodies operate abnormally -Sleep deprivation that lasts for four days or longer becomes uncomfortable and soon becomes unbearable -In animals, forced sleeplessness leads to infections and eventually death, and the same seems to be true for people

-Ernest Hilgard -a split in consciousness in which one part of the mind operates independently of others -while most of the mind is subject to hypnotic suggestion, one part is a hidden observer, watching but not participating -one part of the brain operates as a reporter and interpreter of activities carried out unconsciously by other brain parts
Dissociation
-Ernest Hilgard a split consciousness in which one part of the mind operates independently of others -Hidden observer
What evidence do we have that cognition is involved with learning?
-Latent learning: learning that is not apparent from behavior when it first occurs (rats cognitive mapping of the maze before reinforcement) -Signal relations: environmental stimuli serve as signals that some stimuli are better, more dependable, signals than others ("good" signal allows accurate prediction of the US) -Response-outcome relations and reinforcement: reinforcement is not automatic when favorable consequences follow a response (playing Coldplay when studying for an exam and receiving a high grade, most likely won't continue to play coldplay - you'll know that studying got the good grade and only studying will be strengthened)

-Short term memory: 10-20 sec without rehearsal, capacity of 7 + 2 or 4 + 2 items, chunking makes more space for working memory -Working memory = an elaboration of short-term memory: phonological loop (like short-term memory and with capacity limitations), visuospatial sketchpad, central executive system (attention), episodic buffer ("workbench")
Dreams as Unconscious Wishes
-Sigmund Freud -Freud concluded that our nighttime fantasies provide insight into desires, motives, and conflicts of which we are unaware- a royal road to the unconscious -we are able to express unconscious wishes and desires, which are often sexual or violent in nature -every dream is meaningful, no matter how absurd it may seem -if a dream's message arouses anxiety, the rational part of the mind must disguise and distort it -otherwise, the dream would intrude into consciousness and waken the dreamer -in dreams, one person may be represented by another- or even by several different characters -thoughts and objects are translated into symbolic images -we must distinguish the aspects of it that we consciously experience during sleep and may remember upon wakening from the unconscious wishes and thoughts being expressed symbolically -each dream had to be analyzed in the context of the person's associations to the dream's contents -freud concluded that our nighttime fantasies provide insight into desires, motives, and conflicts of which we are unaware
Dreams as Efforts to Deal with Problems
-dreams reflect the ongoing conscious preoccupations of waking life, such as concerns over relationships, work, sex, or health -the symbols and metaphors in a dream do not disguise its true meaning -the problem-focused explanation of dreaming is supported by findings that dreams are more likely to contain material related to a person's current concerns than chance would predict -for example, among college students, who are often anxious about grades and tests, test-anxiety dreams are common: the dreamer is unprepared for or unable to finish a test, or shows up late for the exam -some psychologists believe that dreams not only reflect our waking concerns but also provide us with an opportunity to resolve them -depressed people's dreams tend to get less negative and more positive as the night wears on, and this pattern predicts recovery -the problem-focused explanation is that dreams reflect the ongoing conscious concerns of waking life and may help us resolve them
Theory 3: figure out the future
-during non-REM sleep the brain is taking the past and trying to figure out how that might relate to the future -REM sleep is actually trying to experience the future-move into the future -REM may be simulations which allow us to make challenges and test possibilities -whats important about what happened to us and how that related to everything else thats happened to us in the past and figuring out what that means about our future -step into that future world with no consequences -allowing us to reach our maximum level of potential
Sociocognitive
-holds that the effects of hypnosis result from an interaction between the social influence of the hypnotist and the abilities, beliefs, and expectations of the subject -we willingly submit tot he suggestions of parents, teachers, doctors, therapists, and television commercials -a reaction to the social demands of the situation and the suggestions of the hypnotist -the researchers concluded that the act of remembering another self involves the construction of a fantasy that accords with the rememberer's own beliefs and also the beliefs of others-in this case, those of the authoritative hypnotist
Cerebrum
-largest part of brain -interprets input from the senses -controls movement -carries out complex mental processes such as learning and remembering -divided into right and left half -each half controls slightly different mental activities -different areas control different functions

Theory 4: Ancestors
-many of the bad dreams we have today, are the same as those experienced by our ancient ancestors -ancestors lived in an environment with all sorts of fatal dangers -the same dangers often show up in dreams today particularly of those in children -ancestors had these bad dreams and gave them to us because they force us to go through those similar threatening events -we occur these accounts so that we are more prepared to survive when we have been training in our dreams -rehearsing stressful events stays with us all for our lives but as we grow up, wild animals are replaced by modern horrors -force us to be prepared for similar events in the waking world
Theory 2: Brain Stem
-particular part of out brain stem that triggers REM sleep -sending up signals to the higher parts of the brain that were random and chaotic -dreams were more physiological than psychological -the result of our higher brain doing its best it could to make sense of meaningless neural impulses -dreams have some pattern but they have no purpose
Experiment 2: Video Game Experiment
-person learns how to play a downhill ski simulator- controls the character -they think that as the brain goes to sleep, it will go back to these images -waken repeatedly during non-REM sleep -had dreams about skiing and later in the night included his own memories -refines memories, improves memories -makes memory useful for the future -person performs better on the simulator the next day -the people who dream about it, perform better the next time -non-REM dreams helps us learn
For Erikson's stage theory, use 1 sentence to describe the main point of how personality develops. What is this a theory of?
-personality is shaped by how individuals deal with a psychosocial crisis at each of the 8 stages in a life span -personality theory
Experiment 3: Rats Sleeping
-places electrodes in a rats brain -sees how the rats neurons fire -see unique patterns of brain activity -as the rat sleeps, the patterns happen again -the patterns of the sleep are direct reflections of the ones they see when the animal is awake -Non-REM: dreams play out as bursts of neural activity which mirrors past experience -REM sleep: memories are replayed- played out as if the animal is actually experiencing moving through a world- world is generated from inside- REM= 5 times longer than non-REM
Experiment 1: Non REM and REM dreams
-recorded brain waves as they slept through the night- put electrodes on the the head -REM- sleep when they have dreams- dream sleep -muscle tone goes down to zero - you become functionally paralyzed -body becomes relaxed -paralyzed- can't make your muscles work -calm and non-responsive -state of paralysis -eyes move rapidly -we dream during non-REM and REM sleep -these two dream states are fundamentally different and affect us in different ways when awakened from non-REM sleep: positive emotions- increase in positive regard -when awakened from REM sleep: very negative-change in mood-amygdala -negative emotion- amygdala is highly active- amygdala specializes in handling unpleasant things -normally you fall asleep in non-REM sleep -people with depression go right into REM sleep and stay in REM-spend too much time in REM sleep=negative thoughts
Cerebellum
-second largest part of the brain -coordinates the actions of your muscles -helps you keep your balance
Right half of cerebrum
-sends impulses to skeletal muscles on the left side of the body -associated with creativity and artistic ability
The Reflex Pathway (finger touching sharp object)

-sleep is critical -sleep is as essential as food -students do 40% worse with a night without sleep than if they had sleep -we need functional sleep: if you don't sleep you will die, and it is a very vulnerable state so there has to be a purpose for it if evolution makes us sleep -benefits of sleep: memory and learning- cognitive functions -sleep enhances memory -you can get more done with sleep -with little sleep for one night, your ability to have high cognitive functioning is decreases significantly -alertness and reaction time are affected with lack of sleep -many car accidents occur because people don't get enough sleep -poor judgements and slow reactions occur with sleep disruption -you can go about 4 or 5 days without sleep -brain waves were very slow without much sleep -affects: memory, irritableness, learning, mood -typing 43123 with their left hand in the morning at night then another group took the same typing test at night then had a good night sleep and did it again in the morning- the group that had the good night sleep performed better
rapid eye movement (REM)
-sleep periods characterized by eye movement, loss of muscle tone, and dreaming -periods of rapid eye movement (REM) alternate with periods of fewer eye movements , or non-REM sleep, in a cycle that recurs about every 90 min. or so. -the REM periods last from a few minutes to as long as an hour, averaging about 20 minutes in length -whenever they begin, the pattern of electrical activity from the sleepers brain changes to resemble that of alert wakefulness -non-REM periods are themselves divided into shorter, distinct stages, each associated with a particular brain wave pattern
How to Test Evolutionary Significance of Behaviour
-speculation full of prejudice & bias. "woman are supposed to be subordinate to males" -test frequency with a marker of evolutionary significance (altruism vs. levels of relatedness) -test twins/cross-cultural studies
spinal cord injuries
-spinal is cut or crushed -axons are damaged and impulses cannot pass through them -results in paraysis (loss of movement)
Signaling Brain
-takes longer for pain impulses to get to the brain and be interpreted than it does for a reflex action to occur -by the time you feel pain, you've already moved your finger away
Challenges to Conducting Competent Research
-the allure of novelty versus replication -the "challenge" of negative findings: stuff nobody wants to publish -selective outcome analysis: cherry picking measures
60 Minutes Part 2
-the sleep deprived have no sense of their limitations -they think they have adapted and that they are fine -sleep deprived people also have major mood swings -their emotional response is not in check with their decision making processes -most of us need 7.5 to 8 hours of sleep -perfectly healthy people were deprived to 4 hours of sleep for 6 nights and the effects were pre-diabetes -they were also hungry- could lead to obesity -sleep deprivation can be a risk factor of type 2 diabetes -affects mating/sex -amygdala and frontal lobe affected -amygdala: emotional responses and sex drives -frontal lobe: rational thinking and it was disconnected -people who don't get much sleep is seen as higher- culture says that not enough sleep is fine -when you get older, you lose deep sleep -lack of sleep can lead to low levels of Leptin which makes you more hungry- With leptin levels that are too low, you can eat and eat and eat and still be hungry
Is there a such thing as empty nest syndrome?
No, some parents report it, but it's not a clinical condition
REM
Rapid eye movement (REM) sleep is a stage of sleep characterized by the rapid and random movement of the eyes. Rapid eye movement sleep is classified into two categories: tonic and phasic.[1] It was identified and defined by Nathaniel Kleitman and his student Eugene Aserinsky in 1953. Criteria for REM sleep includes rapid eye movement, low muscle tone and a rapid, low-voltage EEG; these features are easily discernible in a polysomnogram, the sleep study typically done for patients with suspected sleep disorders

Consciousness
The state of being awake and aware of your surroundings.
Describe how the hypothalamus controls the release of gluccocorticoid (cortisol) and the effects of cortisol.
Upon receiving certain stimulation, the hypothalamus secretes corticotropin-releasing hormone (CRH), which causes the release of adrenocorticotropic hormone (ACTH) from the anterior pituitary. ACTH bring about the release of cortisol by the adrenal cortex. This relationship is called the hypothalamic-pituitary-adrenal axis. The net effect of cortisol is an increase in blood glucose, release of glycerol and fatty acids into blood, and an increase in protein degradation.
Stage 1
Your brain waves become small and irregular, and you feel yourself drifting on the edge of consciousness, in a state of light sleep. If awakened, you may recall fantasies or a few visual images

Identify and briefly describe the function of the six tropic hormones produced by the anterior pituitary.
Tropic hormones stimulate other endocrine glands or tissues to secrete hormones. 1. thyroid-stimulating hormone (TSH): regulates the release of thyroid hormone from the thyroid gland. 2. prolactin (PRL): regulates mammary gland growth and breast milk production in females and may help androgen production in males. 3. follicle-stimulating hormone (FSH)/ 4. luteinizing hormone (LH): collectively called gonadotropins. These hormones act in both females and males, regulating hormone synthesis by the gonads and the production and maturation of gametes. 5. adrenocorticotropic hormone (ACTH): stimulates the adrenal cortex to produce and secrete glucocorticoids (e.g., cortisol). 6. growth hormone (GH): also called somatotropin. GH stimulates cell growth and division and affects most body cells, particularly those within the skeletal and muscular systems. *mnemonic: TP-FLAG

Vision and the Eye
Vision is one of the five special senses. The eye is the organ that controls this sense. Like all special senses, it receives stimuli and sends the impulses to the brain to be interpreted. After receiving light rays, the eye carries the information to the brain where it is translated into vision, or sight. Vision is considered to be the most important sense. About 90% of the information about a person's surroundings reaches the brain through the eyes.

Experimenter Bias
Expectations by the experimenter that might influence the results of an experiment or its interpretation
Classical conditioning occurs when
You learn to associate two different stimuli. No behavior is involved. The first stimulus that you will encounter is called the unconditioned stimulus. An unconditioned stimulus produces a response without any previous learning. This response is called an unconditioned response.

Discuss the survival value of generalization and discrimination
Generalization has survival value because it lets us extend a learned response to the stimuli in a given category-as in fleeing from all dangerous animals Discrimination also has survival value because its lets us limit our learned responses to appropriate stimuli-as in fleeing from a rampaging lion but not from a playful kitten
What are the different stages of prenatal development and what sorts of things characterize these stages (e.g. when is the most vulnerable period—and why? What is the "age of viability" and what does it mean?)
Germinal stage: 0-2 wks (zygote), within 36 hrs = proliferation, 1 wk = implantation Embryonic: 3-8 wks (embryo), recognizably human, cephalocaudal & proximodistal; most vulnerable period because major organs developing - if it gets screwed up, usually results in miscarriage Fetal: 9-38ish wks (fetus), 12 wks: basic structures completed, can detect stimulation and movement (aka "quickening"); 22-26 wks = "age of viability", which means it has 85% chance of survival

Describe how lipid-soluble hormones reach their target cell receptors and the type of cellular change they initiate.
Hormones that are lipid-soluble stimulate cellular activity by binding to intracellular receptors: The hormone-receptor complex activates a region of DNA, resulting in the production of new proteins.
Describe how water-soluble hormones induce cellular changes in their target cells.
Hormones that are water-soluble bind with plasma membrane receptors; the hormone is the first messenger, and it causes the activation of G protein and the formation of a second messenger through an intracellular enzyme cascade. The cellular response may include activation or inhibition of enzymatic pathways, stimulation of growth through cellular reproduction, stimulation of cellular secretions, change in membrane permeability, and muscle contraction or relaxation. The degree of cellular response is a function of both receptor number and receptor interaction.

Hypnosis
Hypnosis
Hypnosis is a temporary state of heightened relaxation and suggestibility during which some (not all) people are able to become so focused that they experience imaginary happenings as if they were real. Hypnosis is not some trans-like, magical state in which people will engage in behaviors that are completely against their "normal, non-hynotized" will. People often believe that a hypnotist can make you do things you would never do, like take your clothes off and run around a crowded room naked. If you would not do this when you are not hypnotized, then you would not do it when you are hypnotized. However, if there is some part of you that would....well then, that may be a different story.

In addition to the waves characteristic of Stage 2, your brain occasionally emits delta waves, very slow waves with very high peaks. Your breathing and pulse have slowed down, your muscles are relaxed, and you are hard to arouse.
Identify the two major characteristics that distinguish classical conditioning from operant condition
In classical condition, the organism forms associations between behaviors it does not control; this form of conditioning involves respondent behavior. In operant conditioning, the organism learns associations between its own behavior and resulting events; this form of conditioning involves operant behavior
Summarize the processes of extinction, spontaneous recovery, generalization, and discrimination
In classical conditioning, extinction is diminished responding when the CS is no longer signals an impending US. Spontaneous recovery is the appearance of a formerly extinguished response, following a read period. Generalization is the tendency to respond to stimuli that are similar to a CS. Discrimination is the learned ability to distinguish between a CS and other irrelevant stimuli.
Describe the process of observational learning, and explain the importance of the discovery of mirror neurons
In observational learning, we observe and imitate others. Mirror neurons, located in the brain's frontal lobes, demonstrate a neural basis for observational learning. They fire when we perform certain actions, or when we observe someone else performing those actions
Animal model
In research, an animal whose behavior is used to derive principles that may apply to human behavior. (i.e. animal studies help to understand stress, learning, obesity, sleep in humans.)
Lesson Summary
In review, let's compare Pavlov's classical conditioning and Skinner's operant conditioning alongside each other. Both classical conditioning and operant conditioning are processes that lead to learning. Classical conditioning pairs two stimuli, while operant conditioning pairs behavior and response. The learning occurs before the response in classical conditioning and after the response in operant conditioning. You learn by association in classical conditioning and by reinforcement or punishment in operant conditioning. Also, classical conditioning always works with involuntary responses, while operant conditioning works with voluntary behaviors. Extinction, an extinction burst, spontaneous recovery, and stimulus generalization are different phenomena that can occur.
Describe some ways to apply operant conditioning principles at school, in sports, at work, and at home
In school, teachers can use shaping techniques to guide students' behaviors. Interactive software and Web sites can provide immediate feedback to students. In sports, coaches can build players' skills and self-confidence by rewarding small improvements. At work, managers can boost productivity and morale by rewarding well-defined and achievable behaviors. At home, we can control our energy usage by comparing recent consumption with past consumption. Parents can reward behaviors they consider desirable, but not those that are undesirable. Individually, we can reinforce our own desired behaviors and extinguish undesirable ones by stating our goals, monitoring the frequency of desired behaviors, and cutting back on incentives as behaviors become habitual

In the tastebuds - roughly 10,000 are distributed throughout the mouth and throat.
Reflex
Inevitable, involuntary response to stimuli
What part of the ear is the most complex?
Inner Ear
Frontal Lobe
Involves judgement, reasoning, problem solving, planning, etc. Damage to this part of the brain can result in being rigid and unreasonable- they show perseveration (repeating actions over and over). They don't have a filter. Interpersonal Stickiness (when someone doesn't pick up social cues that a conversation is over) is also observed. Logorrhea is when someone can't stop talking, and is observed when there is damage with the frontal lobe.
Negative reinforcement
It involves the removal of a negative consequence to increase the likelihood of a response.
Protection of the Eye
It is partly enclosed in a bony socket in the skull. Tears produced in the lacrimal glands constantly clean the eye and keep it moist. The tears flow across the eye and drain through the lacrimal duct into the nasal cavity. Eyelids and eyelashes help keep out foreign materials. Conjunctiva, a mucous membrane, lines the eyelids and covers the front of the eye to provide added protection and moisture.
In relation to the brain, what is "plasticity?"
It means "flexibility" of the brain.

ossicles
Middle Ear It contains three small bones. They receive sound from the vibrations of the tympanic membrane and in turn transmit the sound waves to the inner ear.
What is "misinformation effect" and "source monitoring effect?"
Misinformation: where post-event information leads to an alteration of a person's memory Source monitoring effect: where you make an incorrect guess about where the information /memory came from, SO...the person may think they remember something, when actually, it came from misleading post-event information (misinformation leads to this)
What is morning sickness and what does it indicate when someone has it? Do most pregnant women experience this? Why would it be advantageous to experience morning sickness?
Nausea any time of the day/night; indicates hormone levels through the roof No, some don't experience any symptoms of being pregnant (bad) Advantageous because elevated hormone levels mean decreased risk of miscarriage
NIRS "Near InfraRed Spectroscopy"
Near infrared spectroscopy (NIRS) an optical technique for measuring blood oxygenation in the brain. It works by shining light in the near infrared part of the spectrum (700-900nm) through the skull and detecting how much the remerging light is attenuated. How much the light is attenuated depends on blood oxygenation and thus NIRS can provide an indirect measure of brain activity.
What's the difference between glial cells and neurons?
Neurons are individual cells in the nervous system that receive, integrate, and transmit information, glia cells are found in the nervous system and they provide support for the neurons.
Lobes
Newest part of the brain from an evolutionary standpoint- this is what separates us from animals- this the where we reason, and problem solve, etc.
Are babies born with emotional attachments to their parents? What types of early emotional attachments exist and how do we determine this? How did these different types of emotional attachment styles come about (that is, develop)? How do early emotional attachments influence later relationships?
No - develops over time o secure attachment (60-65%); parenting style = sensitive; future relationships = satisfying long-term o avoidant attachment (20%); parenting style = insensitive (i.e. feeding baby when baby is not hungry); future relationships = shun romance o anxious/ambivalent aka resistant attachment (10-15%); parenting style: inconsistent; future relationships = frequent, short, high-maintenance, needy o disorganized/disorientated attachment (5-10%): parenting style = severe neglect and/or abuse ** as emotional bond to caregivers increases, fear of strangers increases
Is it OK to drink during pregnancy? How does the brain of an infant with Fetal Alcohol Syndrome differ from the brain of a normal infant?
No: Psychologist view drinking as a "dose-effect" phenomenon Smaller, asymmetrical, not developed properly, less fissures and sulci
Is it OK for an obese person to diet when they are pregnant? Why or why not?
No: fetus may not get the macro-nutrients it needs; malnutrition associated with higher risk of birth complications & neurological deficits (i.e. increased rates of schizophrenia)
David Hubel & Torsten Wiesel
Nobel-prize-winning researchers who discovered "feature detectors" within the brain
NREM
Non-rapid eye movement sleep, or NREM, is, collectively, sleep stages 1-3, previously known as stages 1-4. Rapid eye movement sleep (REM) is not included. There are distinct electroencephalographic and other characteristics seen in each stage. Unlike REM sleep, there is usually little or no eye movement during these stages. Dreaming is rare during NREM sleep, and muscles are not paralyzed as in REM sleep. People who do not go through the sleeping stages properly get stuck in NREM sleep, and because muscles are not paralyzed a person may be able to sleepwalk.
Naturalistic observation
Observing behavior as it unfolds in natural settings.
What: -opium: plant substance containing morphine and codeine -opioid: drug derived from opium, or synthetic drug with opium-like effects How: specialized opioid receptors were discovered in 1990's Downside: lethargy, nausea, impaired mental/motor functioning Withdrawal: -almost never life-threatening -severe body pain, insomnia, sweating, anxiety, vomiting, diarrhea, rapid pulse, fever

Summarize Pavlov's contribution to our understanding of learning.
Pavlov taught us that significant psychological phenomena can be studied objectively, and that conditioning principles have important applications, such as by suggesting how some fears are learned and can be treated. He also demonstrated that principles of learning apply across species, although later research modified this finding somewhat by showing that in many species cognition and biological predispositions place some limits on associative learning
Spontaneous recovery
Refers to the unexpected recurrence of a conditioned response after it has shown extinction. Spontaneous recovery is usually short-lived and a weakened version of the conditioned response.
Describe the function of regulatory hormones.
Regulatory hormones influence the secretion of growth hormone, thyroid hormone, and glucocorticoids (e.g., cortisol). Theses are all regulated by negative feedback.
What are the different consequences which can affect a behavior?
Reinforcement: increases response; + (giving a reward for a behavior) or - (taking away the bad thing to increase behavior - ex: taking away shock when rat pushes lever) Punishment: decreases response; + (add something bad like spanking to decrease behavior) or - (take away something like TV for a child when they do something you don't like)
What is "shaping?"
Reinforcements of closer and closer approximations of a desired response; animals don't immediately do the behavior the human wants so the human has to "lead" them in the direction
partial reinforcement
Reinforcing a response only part of the time - results in slower acquisition but more resistance to extinction
continuous reinforcement
Reinforcing the desired response EVERY time it occurs - quicker acquisition but easy extinction
List the hormones released from the hypothalamus that control the anterior pituitary.
Releasing hormones (e.g., TRH, PRH, GnRH, CRH, GHRH) stimulate the release of hormones from the anterior pituitary, and inhibiting hormones (e.g., PIH, GIH) decrease the release of hormones from the anterior pituitary.
What's the difference between a "research" division vs. an "applied" division. What divisions does UNC's psychology & neuroscience department have?
Research is the direct observation and conduction of the experiment while the applied division is the psychology that is put into practice, such as counseling.
What is "spontaneous recovery?"
Response to stimuli even after going through extinction process, but usually less than original respone
Punishers

Retro - can't remember information before injury Antero - can't remember information going forward from injury
Functionalism
School of psychology concerned with how behavior and mental abilities help people adapt and thrive in their environment.
Behaviorism
School of psychology that emphasizes the study of overt, observable behavior. Believes environment shapes behavior.
The new notion of "the whole is greater than the sum of it's parts"
Scientific worldview at the time was analytic, very structuralist: "the whole could be reduced to it's parts", gestalt theorists were more concerned with synthetic reasoning "greater than the sum"

Sedatives & hypnotics
Sedatives and hypnotics depress or inhibit brain activity and produce drowsiness, sedation, or sleep; relieve anxiety; and lower inhibition. Although the depressant compounds do not share a common neural mechanism of action, most of them either decrease the metabolic activity in the brain or increase the transmission of the principal inhibitory neurotransmitter of the brain, gamma-aminobutyric acid (GABA).
Selective Sleep deprivation
Selective sleep stage deprivation is the targeted suppression of one stage of sleep to gain insight into its specific purpose or to replicate some sleep disorders such as sleep apnea.
Phantom Limbs

-insomnia (sleeplessness) -hypersomnia (sleeping too much) -narcolepsy (immediate transition from waking to REM sleep) -sleep apnea (pauses in breathing or shallow breathing during sleep) -parasomnias (nightmares, night terrors, somnambulism)
Sleep Disorders
-sleep loss can affect physiological processes (cognition, mood, suppression of immune system) -sleep restriction = increased hunger
Sleep Loss and Health
sleep deprivation
Sleep deprivation occurs when an individual fails to get enough sleep. The amount of sleep that a person needs varies from one person to another, but on average most adults need about seven to eight hours of sleep each night to feel alert and well rested. Teens need an average of about nine hours of sleep per night, and children need nine hours of nightly sleep or more, depending on their age.
adaptive theory
Sleep is the product of evolution (Webb, 1992). It proposes that animals and humans evolved different sleep patterns to avoid being present during their predators normal hunting times, which typically would be at night. for example, if a human or a prey animal (one predator will eat) is out and about at night, they are more at risk of being eaten. One of the earliest theories of sleep, sometimes called the adaptive or evolutionary theory, suggests that inactivity at night is an adaptation that served a survival function by keeping organisms out of harm's way at times when they would be particularly vulnerable. Evolutionary theory, also known as the adaptive theory of sleep, suggests that periods of activity and inactivity evolved as a means of conserving energy. According to this theory, all species have adapted to sleep during periods of time when wakefulness would be the most hazardous. Support for this theory comes from comparative research of different animal species. Animals that have few natural predators, such as bears and lions, often sleep between 12 to 15 hours each day. On the other hand, animals that have many natural predators have only short periods of sleep, usually getting no more than 4 or 5 hours of sleep each day.
How do emotions develop?
Smiling / laughter: one of the 1st expressions of pleasure - 4-6 wks Fear: 3 mos- wariness, sober stares -> 6 mos- whimpering, looking away -> 7 mos - true fear, crying -> 13-15 mos- separation anxiety
Reinforcement, + or -
Something happening after an action that will increase the likelihood of the action occurring again.
Somnambulism
Somnambulism (often also referred to as Nocturnal Somnambulism) describes a condition in which an individual repeatedly sleep-walks. In Psychology, it is classified as a dissociative disorder, which also includes amnesia, fugue, and multiple personality disorders. Somnambulism is now thought to be a relatively benign disorder, and is usually not treated. However, there is a risk that the person could be injured accidentally (walking into things, falling down stairs, etc.) during sleep walking.

Define the different stages of sleep: - Mention EEG pattern of each
Stage 1: Brief transitional stage of light sleep asleep, EEG: theta waves Stage 2: Light, but slightly deeper than stage 1, characterized by sleep spindles and K complexes (spike in brain wave), EEG: theta waves Stages 3: Deep sleep, breathing and heart rate slow, EEG: theta & delta waves < 50% Stage 4: Very deep sleep, metabolism and brain waves slow down, EEG: delta waves > 50% REM Sleep: Rapid Eye Movement, brain waves & metabolism speed up, EEG: alpha & sometimes beta waves (similarities to being awake but asleep called: paradoxical sleep) -Dreaming correlative during REM
What are some behavioral characteristics associated with the differing stages of sleep (e.g. which stage is it difficult to wake people up from? ETC.)
Stages 1 & 2: May report not have been sleeping Stages 3 & 4: Difficult to awaken, groggy if woken REM: Difficult to wake, but can be done with meaningful stimuli
Stimulants
Stimulants produce behavioral arousal. As with the sedatives and hypnotics, there are a variety of substances, each with a different neural mechanism of action. Examples of stimulants are amphetamine, cocaine, antidepressants, caffeine (the most widely used psychoactive drug in the world), nicotine or tobacco, appetite suppressants, and a variety of exotic plant products. Stimulants vary in strength, legal status, and the manner in which they are taken; however, all stimulants have addictive potential.

How does classical conditioning occur? What factors matter (e.g., timing, saliency of stimulus)?
Stimulus contiguity: timing of the pairing of the UCS & CS): 1) simultaneous presentation (of UCS & CS) - tone & meat are presented and ended at same time, 2) short-delayed presentation - tone begins shortly before meat, but both end at same time, 3) trace presentation - tone is presented & ended right before the meat is presented then ended Saliency of stimulus: stimulus which is most noticeable is more likely a good potential CS (compared with a subtle or difficult-to-notice CS)

Stage 1 (1-17 mins) -Theta waves (light sleep) -Breathing becomes more regular -Heart rate slows -Blood pressure decreases -Could be readily awakened -Hypnic jerks Stage 2 (10-25 mins) -"sleep spindles" (oscillation of brain waves = burst of activity = drifting in and out of consciousness) -Progressively more relaxed -Less responsive to environment Stage 3 and 4 (30 mins) -"slow wave sleep" -Delta waves -Deep sleep -Hard to awaken Stage 5 (REM sleep) -REM = rapid eye movement (brain waves resemble walking patterns) -High frequency beta waves -Vivid dreaming -Extreme relaxation
The Five Sleep Stages
Discuss the importance of cognitive processes in classical conditioning
The early behaviorists' optimism that learning principles would generalize from from one response to another and from one species to another has given way to the understanding that conditioning principles are influenced by our thoughts, perceptions, and expectations. In classical conditioning, humans and other animals learn when to "expect" a US, and their awareness of the link between stimuli and responses can weaken associations
Physiological psychology
The field of psych studying how the body affects behavior- genetics, nervous system & endocrine system.
Structuralism
The first school of thought in psychology, concerned with introspection and analysis.
Associative learning
The formation of associations or connections among stimuli and behavior
How does the depth to which we encode information (i.e. structural vs. phonemic vs. semantic encoding) affect durability of memory?
The more shallow the processing, the less durable the memory is. -Structural: visual, least durable -Phonemic: sound, better durability -Semantic: meaning / understanding** best durability
How might you suggest that "encoding specificity principle" is related to "reinstating the context?"
The more specific a retrieval cue, the more likely it is that you will recall the memory -- why if you "reinstate the context", chances are that there will be a retrieval cue which is able to retrieve the memory you need.
restorative theory
The other major theory of why organisms sleep. sleep is necessary to the physical health of the body. During sleep, chemicals that were used up during the days activities are replenished cellular damage is repaired. According to the repair and restoration theory of sleep, sleeping is essential for revitalizing and restoring the physiological processes that keep the body and mind healthy and properly functioning. This theory suggests that NREM sleep is important for restoring physiological functions, while REM sleep is essential in restoring mental functions. Support for this theory is provided by research that shows periods of REM sleep increase following periods of sleep deprivation and strenuous physical activity. During sleep, the body also increases its rate of cell division and protein synthesis, further suggesting that repair and restoration occurs during sleeping periods.
Describe the gross anatomy and cellular structure of the pancreas.
The pancreas situated between he duodenum of the small intestine and the spleen and directly posterior to the stomach. It performs both exocrine and endocrine activities; thus, it is considered a heterocrine, or mixed, gland. The pancreas is mostly composed of groups of cells called pancreatic acini. Acinar cels are involved in exocrine activities and produce an alkaline pancreatic secretion (juice) that is secreted through pancreatic ducts into the small intestine. The pancreatic juice aids digestion.

Describe the thyroid gland location and anatomy.
The thyroid gland is a butterfly-shaped gland anterior to the trachea and inferior to the larynx.
Discuss how thyroid hormones are produced, stored, and secreted.
The thyroid gland is composed of spherical thyroid follicles. The wall of each folic is formed by cuboidal epithelial cells, called follicular cells, which surround a central lumen. That lumen houses a viscous, protein-rich fluid termed colloid. Iodine is attached to tyrosine amino acids of thyroglobulin within the colloid of thyroid follicles. Then pre-T3 and pre-T4 structures are formed. Thryoglobulin with pre-T3 and pre-T4 is lated transported into the follicular cels. Within lysosomes of follicular cells, thyroid hormone (T3, T4) is cleaved from thyroglobulin and released into the blood by endocytosis.
Describe the two primary factors that affect the concentration level of a circulating hormone.
The two primary factors that influence hormone concentration are hormone synthesis by endocrine glands and hormone elimination by the liver, kidneys, and target cells.

Dreams As Wish of Fulfillment (Freud): -Manifest content (consists of the plot of a dream at the surface level) -Latent content (hidden or disguised meaning of the event in the plot) Problem-Solving View (Cartwright): -Creative problem-solving because dreams are not restrained by logic or realism Activation-Synthesis Model (Hobson and McCarley): -Dreams are simply the by-product of bursts of activity emanating from sub-cortical areas of the brain (mean nothing) -Random neural firing (memory activation, perceptual experience) occurs during sleep states; dreams are merely your brain's attempt at creating a story to explain the random firing
Theories of Dreaming
What have researchers discovered about hypnosis? Myths about hypnosis?
Theories: role playing, altered state of consciousness (Hilgard's disassociative theory = splitting of consciousness, ex: highway hypnosis) Features: anesthesia, sensory distortions/hallucinations, disinhibition, posthypnotic suggestions & amnesia Myths: it's voluntary & not everyone can be hypnotized (you can't be hypnotized against your will); it does not have a good track record for effectiveness as a TX for obesity, smoking, etc.

synapse
a junction where information is transmitted from one neuron to another - where neurons meet
What is the relationship between tolerance and withdrawal?
A person experiences tolerance because the body is adapting. It prefers to be at a homeostatic state so when a drug changes things, e.g. increase CNS arousal, eventually—over repeated exposure, the body will develop mechanisms which will compensate/counter-act the drugs' effects as an attempt to bring the body back to homeostasis. It is these compensatory processes which are causing the tolerance. Withdrawal effects are essentially the compensatory mechanisms mentioned above. If you suddenly didn't drink (or significantly decreased the amount you drink), then your body's compensatory mechanisms would be evident. That is, you would see evidence that your body has increased its level of arousal (since you no longer have enough alcohol to balance this increased level of arousal)—this is why, for example, you may see someone being jittery when withdrawing from alcohol. This is also the reason that it makes sense that withdrawal effects are usually effects which are opposite to that of the drug's.

You should also know that a person's blood alcohol concentration (BAC) can continue to rise even while he or she is passed out.
Which drug is the most dangerous to withdraw from after heavy usage?
Alcohol, can be fatal
What is the most physically harmful drug?
Alcohol: damages liver and brain, etc.
Opiates
All drugs in the opiate class act on opiate receptors in the brain. They mediate relief from pain and produce feelings of euphoria. Opiates, which are referred to as narcotics by scientists and medical practitioners, are highly addictive and can either be natural, semisynthetic, or synthetic. Natural opiates such as opium are derived from the opium poppy. The active ingredients of opium are morphine and codeine. The most common semisynthetic opiate is heroin, which is five to ten times more potent than morphine. Examples of synthetic opiates include methadone and the prescription pain medication Demerol.

What are the differences & similarities between classical conditioning, operant conditioning, and observational learning?
Classical Conditioning (Pavlov): CS (tone) + US (food) = UR (drool) until CS = CS (still drool, but without food) Operant Conditioning (Skinner): behavior is followed by some sort of consequence; reinforcement increases behavior; punishment decreases behavior Observational Learning: vicariously learning by watching someone else doing operant / classical conditioning
Identify the major similarities and differences between classical and operant conditioning
Classical and operant conditioning are similar in being forms of associate learning. Bother also involve acquisition, extinction, spontaneous recovery, generalization, and discrimination. And bother are influences-and sometimes constrained- by cognitive processes and biological predispositions. These two forms of learning differ in an important way. In classical conditioning, an organism associates different stimuli that it does not control and responds automatically. In operant conditioning, an organism associates its own behaviors with their consequences.
Hypnosis
a procedure in which a practitioner suggests changes in the sensation, perceptions, thoughts, feelings, or behavior of the subject -have to be suggestible -won't be forced against their will -won't increase accuracy -won't be able to do something you normally can't do
higher-order conditioning
a procedure in which the conditioned stimulus in one conditioning experience is paired with a new neutral stimulus, creating a second (often weaker) conditioned stimulus. For example, an animal that has learned that a tone predicts food might then learn that a light predicts the tone and begin responding to the light alone (a.k.a. second-order conditioning)
schedules of reinforcement
a program that determines when a response will be followed by a reinforcer; influences how a response is learned and maintained
top-down processing
a progression from the whole to the elements
Dependence
a psychologic craving for, habituation to, abuse of, or physiologic reliance on a chemical substance. See also drug abuse, drug addiction.
Define classical conditioning and behaviorism, and describe the basic components of classical conditiong
Classical conditioning is a type of learning in which an organism comes to associate stimuli. Pavlov's work on classical conditioning laid the foundation for behaviorism, the view that psychology should be an objective science that studies behavior without reference to mental processes. In classical condition, a UR is an event that occurs naturally, in response to some stimulus. A US is something that naturally and automatically triggers the unlearned response. A CS in classical conditioning is an originally neutral stimulus that, through learning, comes to be associated with some unlearned response. A CR is the learned response to the originally neutral but now conditioned stimulus.
Describe the timing requirements for the initial learning of a stimulus-response
Classical conditioning occurs most readily when a CS is presented just before a US, preparing the organism for the upcoming event. This finding supports the view that classical conditioning is biologically adaptive.
Pavlov
Classical conditioning researcher UR/US/CR/CS tone/dog/saliva/food
Describe some used of classical conditioning to improve human health and well-being
Classical conditioning techniques are used in treatment programs for those recovering from alcohol and other drug abuse and to condition more appropriate responses in therapy for emotional disorders. The body's immune system also appears to respond to classical conditioning
What type of learning is "taste aversion"? How does it differ from the typical type of this learning?
Classical conditioning: neutral stimulus/CS (food) has been paired with an US (sickness), which causes an UR (nausea) which makes you feel nauseous in the future when you see it (CR); different because it only requires one trial while classical conditioning usually requires multiple
What association is being made in classical conditioning vs. operant conditioning?
Classical: a neutral stimulus / unconditioned stimulus (e.g., a tone) becomes associated with a conditioned stimulus (e.g., food) Operant: behavior and consequence
temporal lobe
a region of the cerebral cortex responsible for hearing and language
biological rythms
a regular fluctuation in a biological system -a biological clock in our brain governs the waxing and waning of hormone levels, urine volume, blood pressure, and even responsiveness of brain cells to stimulation -these rhythms are endogenous
What evidence do we have that there are biological limitations and / or predispositions to learning?
Classical: conditioned taste aversion - makes you feel ill after only one bad experience, extended delay between CS & US, evolutionary adaptation Operant: instinctive drift - learn things against biological instincts (ex: raccoons would pick up 1 coin, but after the researchers tried to train raccoons for 2 coins they just instinctually rubbed them together as they would with food)

What are "schedules of reinforcement" and how do they influence behavior?
Continuous reinforcement: reinforcement after every single target behavior Intermittent reinforcement: -Fixed-ratio schedule: reinforcement given based on a fixed number of responses (e.g., every third responses); lower resistance to extinction (factory work) -Variable-ratio schedule: reinforcement given based on an average number of responses (e.g., reinforcement is given, on average every 4 responses); higher resistance to extinction (slot machines) -Fixed-interval schedule: reinforcement given based on the first response given after a fixed amount of time has passed (e.g., reinforcement is given if a rat pulls a lever after 4 seconds have passed); lower resistance to extinction -Variable-interval schedule: reinforcement given based on the first response given after an average amount of time has passed (e.g., reinforcement is given if a rat pulls a level, on average, after 3 seconds have passed); higher resistance to extinction
Explain why correlations cannot prove that watching violent TV causes violent behavior, and cite some experimental evidence that helps demonstrate a cause-effect link
Correlations show relationships, but not the direction of influence. Correlational studies show that violence viewing and violent behavior are linked, but they do not prove that watching violent TV causes children to become violent. Children who behave violently may enjoy watching violence on TV, or some third factor may cause children both to behave violently and to prefer watching violent programs. To prove cause and effect, researchers have designed experiments in which participants view violence and other do not. Later, given an opportunity to express violence, the people who viewed violence tend to be more aggressive and less sympathetic. Two factors-imitation and desensitization-seem to contribute to the violence effect

Define learning as a mental change that may or may not be associated with changes in behavior. Permanent changes in the way they represent the environment because of experience.
Stage 4
Delta waves have now largely taken over, and you are in deep sleep. It will probably take vigorous shaking or a loud noise to awaken you. Oddly, though, if you talk or walk in your sleep, this is when you are likely to do so. The causes of sleepwalking, which occurs more often in children than adults, are still unknown, but they may involve unusual patterns of delta wave activity
continued use maintained by the avoidance of withdrawal symptoms; usually accompanied by increases in negative physical, psychological, occupational, and interpersonal consequences -physical (biological adaptation of body cells and processes due to excessive drug use. Discontinued use followed by physiological withdrawal) -psychological (psychological adaptation to continued drug use that renders user vulnerable to continued use to avoid negative mental/emotional consequences
Dependence

Diminishing of a conditioned response Occurs in: Classical - when an unconditioned stimulus doesn't follow a conditioned stimulus Operant - response no longer gets reinforced
What does the dual-coding theory (Paivio) suggest about enriching encoding?
Dual-coding theory: Holds that memory is enhanced by forming both semantic and visual codes since either can lead to recall; by using two or more coding methods, you are more likely to remember something than if you used only one coding method.
Spontaneous recovery

Describe some of the ways that biological predispositions can affect learning by classical conditioning
Early behaviorists believed that any natural response could be conditioned to any neutral stimulus in any living organism. Learning theorists have abandoned this belief. Each species is biologically prepared to learn associations-such as humans' fear of spiders and snakes, or rats' aversion to tastes associated with nausea-that enhance its survival. Outside the laboratory, a CS tends to have a natural association with the US it predicts
-anesthesia -sensory distortions -disinhibition -posthypnotic suggestions and amnesia (hypnotic influences that continue to work after hypnotic state has been lifted)
Effects produced through hypnosis
What is the EEG and how is it used to differentiate between different stages of sleep?
Electroencephalogram = device that monitors the electrical activity of the brain over time by means of recording electrodes attached to the surface of the scalp -- different stages of sleep have different electrical activity

this is the part of the brain that is associated with threat detection Trying to decide if there are harmful things in one's environment. It's also involved in emotional expression/experience. Kluver-Bucy syndrome is a syndrome where the amygdala is damaged, which results in docility and passivity in a person, as well as hyper-orality (putting a lot of things in their mouth), as well as hyper-sexuality. Stimulating the Amygdala can cause aggressiveness and potential paranoia.

How does language develop? Know the concepts involved, e.g. overregularizations, overextensions, underextensions, telegraphic speech, ETC.
• 1- 5 mos.: reflexive communication; cooing • 6-18 mos.: babbling • 10-13 mos. first words • 12 - 18 mos.: one word sentences o receptive vs. productive vocabulary o overextension: one word for many things o underextension: only 1 doll is "doll" • 18-24 mos.: vocabulary spurt • towards end of 2 yrs: telegraphic speech (short, to the point) & fast mapping (might remember after only hearing it once) • towards end of 3 yrs.: overregularizations (odd, grammatical errors - i.e. adding "ed" to every word pertaining to the past) • 5 yrs.+: well-developed and complex grammar
autonomic nervous system
-controls involuntary actions
Brain
-controls most systems in the body -directs a response after receiving an impulse -sends it back through the spinal cord and out to the peripheral nervous system
Left half of cerebrum
-controls the right side of the body -associated with mathematical skills and logical skills
Somatic nervous system
-controls voluntary actions
Theory 5
-dreams reflect our waking concerns -dreams tend to reflect peoples emotional concerns and things that preoccupy them in their social lives
Dreams as Thinking
- the cognitive approach to dreaming emphasizes current concerns, but it makes no claims about problem solving during sleep -dreaming is simply a modification of the cognitive activity that goes on when we are awake -we construct reasonable simulations of the real world, drawing on the same kinds of memories, knowledge, metaphors, and assumptions about the world that we do when are are not sleeping -content of our dreams may include thoughts, concepts, and scenarios that may or may not be related to our daily problems -we are most likely to dream about families, friends, studies, jobs, or recreational interests- topics also occupy our waking thoughts -brain is doing the same kind of work during dreams as it does when we are awake -this view predicts that if a person could be totally cut off from all external stimulation while awake, mental activity would be much like that during dreaming -cognitive approach also predicts that as cognitive abilities and brain connections mature during childhood, dreams should change and mature, and they do -young children may experience visual images during sleep, their cognitive limitations keep them from creating true narratives -their dreams are infrequent and tend to be bland, static, and about everyday things -but, as they grow up, their dreams gradually become more and more intricate, dynamic, and story like -the cognitive approach emphasizes current concerns, but makes no claims about problem-solving during sleep
What is the "cephalocaudal" vs. "proximodistal" principle and what do they have to do with prenatal development?
-Cephalocaudal: development moves from head to toes -Proximodistal: core things develop first (i.e. heart, etc.)
Circadian Rhythms in Humans
-Deepest sleep: 2:00 AM -Lowest Body Temperature: 4:30 AM -Sharpest Blood Pressure Rise: 6:45 AM -Melatonin Secretion Stops: 7:30 AM -Highest Alertness: 10:00 AM -Best Coordination: 2:30 PM -Fastest Reaction Time: 3:30 PM -Greatest Cardiovascular Efficiency and Muscular Strength: 5:00 PM -Highest Blood Pressure: 6:30 PM -Highest Body Temperature: 7:00 PM -Melatonin Secretion Starts: 9:00 PM
How do earlier vs. later behaviorists differ on their opinion of the role of cognition in learning?
-Earlier: internal processes don't contribute at all to behavior -Later: internal processes and behavior are related but it doesn't really need to be studied -Now: internal processes and cognition relate to learning and behavior
Why do we study Biological Rhythms?
-Effectiveness of medicines when taken at different times of the day -Look at alertness and performance on the job-when they should have breaks -Designing of our days to take better advantage of our bodies natural tempos
The Mental Benefits of Sleep
-Sleep contributes to memory consolidation, a process by which the synaptic changes associated with recently stored memories become durable and stable, causing memory to become more reliable -Improvements in memory have been associated most closely with REM sleep and slow-wave sleep, and with memory for specific motor and perceptual skills -When people or animals learn a perceptual task and are allowed to get normal REM sleep, their memory for the task is better the next day, even when they are awakened during non-REM periods -But when they are deprived of REM sleep, their memories are impaired -If sleep enhances memory, perhaps it also enhances problem solving, which relies on information stored in memory -German researchers gave volunteers a math test requiring them to generate one string of numbers from another and to deduce the final digit in the new sequence as quickly as possible -The volunteers were not told about a hidden shortcut that would enable them to calculate the final digit almost immediately -One group was trained in the evening and then got to snooze for eight hours before returning to the problem -Another group also got trained in the evening but then stayed awake for eight hours before coming back to the problem -A third group was trained in the morning and stayed awake all day, as they normally would, before taking the test -Those people who got the nighttime sleep were nearly three times likelier to discover the hidden shortcut as those in the other two groups
The Mental Consequences of Sleeplessness
-Sleep is also necessary for normal mental functioning -Chronic sleep deprivation increases levels of the stress hormone cortisol, which may damage or impair brain cells that are necessary for learning and memory -New brain cells may either fail to develop or mature abnormally -After a loss of even a single night's sleep, mental flexibility, attention, and creativity all suffer -Several days of staying awake, people may begin to have hallucinations and delusions -Sleep deprivation rarely reaches that point, but people frequently suffer from milder sleep problems -10% of adults are plagued by chronic insomnia- difficulty in falling or staying asleep -Insomnia can result from worry and anxiety, psychological problems, physical problems such as arthritis, and irregular or overly demanding work and study schedules. The result can be grogginess the next day -Another cause of daytime sleepiness is sleep apnea, a disorder in which breathing periodically stops for a few moments , causing the person to choke and gasp -Sleep apnea has several causes, from blockage of air passages to failure of the brain to control respiration correctly, and overtime it can cause high blood pressure and irregular heartbeat -In narcolepsy, another serious disorder, an individual is subject to irresistible and unpredictable daytime attacks of sleepiness or actual sleep, lasting from 5 to 30 minutes -A quarter of a million people in the US suffer from this condition, many without knowing it -Narcolepsy seems to be caused by the degeneration f certain neurons in the hypothalamus, possibly due to an autoimmune malfunction or genetic abnormalities -The most common cause of sleepiness is staying up late and, not allowing yourself to get enough sleep at night -2/3 of all Americans get fewer than the recommended seven or eight hours of sleep and American students get only about six hours a night on average -Most need more than six hours for optimal performance and many adolescents need ten -When people don't get enough sleep, they are more likely to get into traffic and work accidents
The Stages
-This sequence of stages takes about 30 to 45 minutes. Then you move back up the ladder from Stage 4 to 3 to 2 to 1. At that point, about 70 to 90 minutes after the onset of sleep, something peculiar happens. Stage 1 does not turn into drowsy wakefulness, as one might expect. Instead, your brain begins to emit long bursts of very rapid, somewhat irregular waves. Your heart rate increases, your blood pressure rises, and your breathing gets faster and more irregular. Small twitches in your face may occur. You have entered the realm of REM. -brain is extremely active while the body in entirely inactive -it is during these periods that vivid dreams are likely to occur. People report dreams when they are awakened from non-REM sleep too -REM and non-REM sleep continue to alternate throughout the night, with stages 3 and 4 tending to become shorter or even disappear and REM periods tending to get longer and closer together as the hours pass -this pattern may explain why you are likely to be dreaming when the alarm goes off in the morning -But these cycles are far from regular- the time between REM and non-REM is highly variable, differing from person to person and also within any given individual
Experiment 5: Statistics
-collected REM and non-REM dreams breaking each one down into its basic elements and turning each element into a number -coded the entire dream series in terms of various elements -who are the characters, emotions, the settings, and then they enter these numbers into a spreadsheet -can tell us how often we dream about sex and whether this involves our partner or a celebrity and how often we have bad dreams -telling us about the dreams of an individual-see dream series and find patterns and get a better idea of the person's dream life-comparing a person's dream elements with the norm -man's dreams showed unhappiness-80% of his dreams include unhappy events-the average occurrence of misfortune is 33% -almost all of the dream characters are women -interactions between these women were negative -concerns about relationship issues and overwhelmed by negative factors-feels like he has no control over it -5 years later- the man divorced
Does the Menstrual Cycle Affect Moods?
-What does the evidence actually show? -Many women do have physical signs associated with menstruation, including cramps, breast tenderness, and water retention, although women vary tremendously in this regard. And of course, these physical symptoms can make some women feel grumpy or unhappy, just as pain can make men feel grumpy and unhappy -emotional symptoms specifically associated with menstruation-notably, irritability, and depression- are pretty rare, which is why we put "PMS" in quotation marks -more people claim to have symptoms than actually do -in reality fewer than 5% of all women have such symptoms predictably over their cycles -if true PMS is relatively uncommon , then why do so many women think they have it? -Possibilities: -they tend to notice feelings of depression or irritability when these moods happen to occur premenstrually but overlook times when such moods are absent premenstrually -they may label symptoms that occur before a period as "PMS" (I am irritable and cranky; I must be getting my period) -a women's perceptions of her own emotional ups and downs can also be influenced by cultural attitudes and myths about menstruation -some studies have encouraged biases in the reporting of premenstrual and menstrual symptoms by using questionnaires with gloomy and negative titles -they do not include that PMS is nonexistent. They do not deny that some women in some months, have unpleasant moods before or during their periods. However, the accumulated research shows clearly that more women think they have PMS symptoms than they actually do and that fewer women need to be treated for it than commonly assumed -the really important question is whether PMS affects women's ability to work -empirical research has failed to establish an connection between phase of menstrual cycle and real-world behavior in the vast majority of women. There is no relationship between phase of the menstrual cycle and work efficiency, problem solving, college exam scores, creativity, or any other behavior that matters in real life -in the workplace, men and women report similar levels of stress, well-being, and ability to do the work required of them- and it doesn't matter whether the women are premenstrual, menstrual, post-menstrual, or non-menstrual
Testings and Findings
-When participants in these studies have been allowed to sleep, eat, and work whenever they wished, free from tyranny of timepiece, a few have lived a day that is much shorter or longer than 24 hours. If allowed to take daytime naps, however, most people soon settle into a day that averages about 24.3 hours -Stefania Follini spent 4 months in a New Mexico cave, 30 feet underground, as a part of an Italian study on biological rhythms. Her only companions were a computer and two friendly mice. In the absence of clocks, natural light, or changes temperature, she tended to stay awake 20 to 25 hours and then sleep for 10. Because her days were longer than usual, when she emerged, she thought she had been in the cave for only 2 months
seasonal affective disorder (SAD)
-a controversial disorder in which a person experienced depression during the winter and an improvement of mood in the spring -some people become depressed during particular seasons, typically winter, when periods of daylight are short -during the winter months, SAD patients report feelings of sadness and drowsiness -when people get the winter blues, the reason could also be that they hate cold weather, are physically inactive, do not get outside much, or feel lonely during the winter holidays
melatonin
-a hormone secreted by the pineal gland; it is involved in the regulation of circadian rhythm -melatonin levels secreted help control sleep
internal desynchronization
-a state in which biological rhythms are not in phase (synchronized) with one another -under normal conditions, the rhythms governed by the SCN are synchronized -but when your normal routine changes, your circadian rhythms may be thrown out of phase with one another -internal desynchronization occurs when people take airplane flights across several time zones. -sleep and wake patterns usually adjust quickly, but temperature and hormone cycles can take several days to return to normal -the resulting jet lag affects energy level, mental skills, and motor coordination -internal desynchronization also occurs when workers must adjust to a new shift- efficiency drops, the person feels tired and irritable, accidents become more likely, and sleep disturbances and digestive disorders may occur
Dreams as Interpreted Brain Activity
-activation-synthesis theory: the theory that dreaming results from the cortical synthesis and interpretation of neural signals triggered by activity in the lower part of the brain-draws heavily on physiological research -they are the result of neurons firing spontaneously in the lower part of the brain, in the pons, during REM sleep -these neurons control eye movement, gaze, balance, and posture, and they send messages to sensory and motor areas of the cortex responsible during wakefulness for visual processing and voluntary action -signals originating in the pons have no psychological meaning in themselves -the cortex tries to make sense of them by synthesizing, or integrating, them with existing knowledge and memories to produce some sort of coherent interpretation -this is just what the cortex does when signals come from sense organs during wakefulness -one part of the brain interprets what has gone on in another -when neurons fire in the part of the brain that handles balance, for instance, the cortex may generate a dream about falling -when signals occur that would ordinarily produce running, the cortex may manufacture a dream about being chased -because the signals from the pons occur randomly, the cortex's interpretation-the dream- is likely to be incoherent or confusing -because the cortical neurons that control the initial storage of new memories are turned off during sleep, we typically forget out dreams upon waking unless we write them down or immediately recount them to someone else -the brain stem, sets off responses in emotional and visual parts of the brain -at the same time, brain regions that handle logical thought and sensations from external world shut down. -dreams tend to be emotionally charged, hallucinatory, and illogical -the activation-synthesis theory holds that dreams occur when the cortex tries to make sense of spontaneous neural firing initiated in the pons during REM sleep
suprachiasmatic nucleus (SCN)
-an area of the brain containing a biological clock that governs circadian rhythms -area of the hypothalamus that controls your bodies internal clock -circadian rhythms are controlled by a biological clock -neural pathways from special receptors in the back of the eye transmit information to the SCN and allow it to respond to changes in light and dark -the SCN then send out messages that cause the brain and the body to adapt to these changes -the SCN regulates the fluctuating levels of hormones and neurotransmitters, and they in turn provide feedback that affects the SCN's functioning -for example: during the dark hours, one hormone regulated the the SCN, melatonin, is secreted by the pineal gland, deep within the brain. The pineal gland responds to light and dark via complex connections that originate in the back of the eye. When you go to sleep in a darkened room, your melatonin level rises; when you wake up in the morning to a lightened room, it falls. Melatonin in turn, appears to help keep the biological clock in phase with the light-dark cycle
Reflex
-an automatic response that occurs very rapidly without conscious control -help protect the body
Studying Brains Across Species
-animals used in neuropsych research (ethics? illuminates workings of brain, similarities and differences across species) -When brains are compared, we can hypothesize about how our brains evolved over time.
Psychological dependence
Psychological Dependence is an emotional need for a drug or substance that has no underlying physical need. For example, people who stop smoking recover physically in a short time. The emotional need for nicotine, however, is much more difficult to overcome. They continually think they need the nicotine to stay calm even though there is no physical need. The drug for the addict is similar to what a security blanket would be for a child (or some adults).
