Psych 1101 Cornell FINAL

What is the importance of pre-registration?

- Distinguishes confirmatory/exploratory analyses - Reduces p-hacking

Know some of the benefits of laughter

- Laughter regulated by the same reward circuit that makes us feel good • Endorphins are released during laughter, just like after sex and eating. -Reduces the presence of stress hormones - Decreases muscle tension - Increases the presence of positive immune markers - In diabetics, less increase in blood sugar after a meal

What are the primary functions of emotions?

- Motivation to act -Physiological arousal - Subjective feeling - Changes in thought - Changes in expression (body and face)

What You Believe Changes What You Taste?

- People believe that the color associated with what you eat (food dyes) is what determines the flavor and what you will taste. - If you believe you drinking from a more expensive bottle then it tastes better.

Problems in the practice of science?

- Replicability -p-hacking - fraud

Perception is a difficult problem

- The mind uses a number of "tricks" to make sense of all of the incoming sensory information efficiently. ex. visual perception: our mind makes certain assumptions about the environment despite having limited data to work with. Happens quickly, automatically, uncontrollably - Shadows make surfaces darker ex. When we see a surface in shadow, we automatically assume it is lighter than it look

What is emotional valuation, and how do values placed on emotional states differ between cultures (especially Eastern vs Western cultures)?

- culture shapes emotion, starting with emotional response - Japanese-American infants more reactive than Chinese-American infants - what cultures value their ideal emotional state and what id that preferred emotional stated ex. Asking kids which one they would rather be, excited smile or happy. Kids choose the more excited smile. Kids in the West choose a high arousal excited state. Twainis and Asian students much less valuing excited positivity. - looking at a children's book and coding for how big the smile is, more pictures of a calm smile in Eastern books rather than Westerners.

3. Our Musical Tastes Are Set (On Average) At Age 13(For Girls) And 14 (For Boys)

- for young men and women ages 13 and 14 is when there muscial preference are set.

How Drugs Affect Neurotransmitters

- influence the chemical precursors of a transmitter substance - prevent the storage of the transmitter substance in vesicles - inhibit or stimulate the release of the transmitter substance - block postsynaptic receptors - block reuptake of free-floating transmitter substance

Know what valid and reliable means in terms of measurement

- informant ratings are particularly valuable when self-ratings are impossible to collect or when their validity is suspect They also may be combined with self-ratings of the same characteristics to produce more reliable and valid measures of these attributes .Self-report personality tests show impressive validity to a wide range of important outcomes.

Perception

- making sense of the information,changing it into something useful

The better-than-average effect and some ways it's been shown

- people even report that they are better than average at how good they are at assessing themselves without bias - people demonstrate this effect in nearly every domain and career that has been studied

Functional magnetic resonance imaging (fMRI)

- relies on blood flow in the brain. - measures the changes in oxygen levels in the blood and does not require any substance to be injected into the participant. - good spatial resolution and poor temporal resolution - not very precise when the activity occurred.

Challenges to Piaget's theory

- researchers who study cognitive development ask whether changes in children's thinking are gradual and continuous or sudden and discontinuous. - The most basic question about child development is how nature and nurture together shape development. Nature refers to the genes we receive from our parents. Nurture refers to the environments, social as well as physical, that influence our development.

2. Blushing Is Likely An Adaptive Signal

- response to embrassment or shame - adaptive signal takes you to know there is a norm and that you have violated as well as an audience that knows that you violated a norm. - people who blush more trustworthy because tell others you care about norms

Gestalt properties of object perception

- similarity- your brain lumps things together when they have a similar texture - proximity- your brain lumps things together because they are close together - closure: incomplete information your brain completes for you, brain automatically closing that gap - common movement: when things move together you are more likely to perceive as objects - good continuation: one line seems continence so don't perceive them as two

What happens in a dichotic listening task?

- wearing headphones and presented with two different streams of audio, you cant process both - simple to shift attention and focus on one and decode one stream - you can flip back and forth

The McGurk Effect

- when a person perceives that another's lip movements do not correspond to what that individual is saying. - occurs when an individual perceives a mismatch between the auditory speech sounds they hear and the visual movements they see while someone is speaking.

Three main types of learning and how they differ from each other (habituation, classical, operant conditioning)

1. Habituation (non-associative) - decline in the tendency to respond to stimuli that are familiar due to repeated exposure ex. clock ticking, traffic noise, trains• - keeps us focusing on new objects and events 2. Classical (Pavlovian) Conditioning (associative) - learning of an association based on the repeated presentation of paired stimuli 3. Operant (Instrumental) Conditioning (associative) - is a process by which humans and animals learn to behave in such a way as to obtain rewards and avoid punishments.

Know the basic theories about humor•

1. Incongruity: Punchline forces you to reframe something/switch frames of reference. 2. Superiority: unny-ness is explained by the sudden realization that we are better than the butt of the joke. 3. Tension Release: We laugh when something builds up tension then relieves it 4. Play/Mock Aggression: Play usually takes the form of mock aggression such as chasing, wrestling, biting, and tickling

What strategies might be used to improve happiness?

1. Interact With People: There is a large amount of evidence that social support is linked with happiness. 2. Be In The Moment: being present with whatever we are seems to matter a lot more than you might think. (Wandering minds = less happiness) 3. Favor Relative Over Absolute: ex earning more or less than others at your job. 4. Seek Experiences Instead Of Stuff: Using your money to purchase experiences rather than material goods leads to greater happiness and satisfaction 5. Spend $ On Others 6. Mind Your "Peaks" And "Ends: When judging our experience we focus on the most extreme emotional point (the "peak") and the last thing we experienced (the "end") 7. Find Religion (Or Something Similar)• Religious people, on average, are happier. 8. Be Grateful 9. Act Happy (Smile) Large-scale studies have shown that just smiling leads to an elevated mood.

• Be able to know which is the UCS, CS, UCR, CR.•

> Unconditioned Stimulus (US or UCS) such as food or shock that causes a reflexive response > Paired with a neutral stimulus (like a bell, light, or tone) that does not normally cause a reflexive response, the Conditioned Stimulus (CS) > Conditioned Stimulus causes the response without the need for the Unconditioned Stimulus > unconditioned response (UCR): natural (unlearned) behavior to a given stimulus > Conditioned response (CR) The response that is elicited by the conditioned stimulus after classical conditioning has taken place.

Positive Reinforcement

A "reinforcer" is the thing that increases the behavior > Can be "Primary" (e.g., food) or "Secondary" (e.g., money)

Know the basic structure of the prisoners dilemma

A classic paradox in which two individuals must independently choose between defection (maximizing reward to the self) and cooperation (maximizing reward to the group). - Economic game where you are asked to imagine that you and someone else have been arrested for a crime. Then asked to confess and integrated in a separate room. - If the police tell you you confessed, they will be more lenient if you both confess to the crime in separate rooms and be given a mid-level sentence of 5 years. - If they confess and they don't say anything then you're screwed. - If you both keep your mouth shut then minimum sentence of a year. - If you know they are going to keep their mouth shut and you say that you both did it then your partner is locked up for twenty years. ex. professor doing extra credit on the exam

Diffuse optical imaging (DOI)

A neuroimaging technique that infers brain activity by measuring changes in light as it is passed through the skull and surface of the brain.

What is free riding?

A situation in which one or more individuals benefit from a common-pool resource without paying their share of the cost.

The affective and cognitive components of happiness/howthey are assessed

Affective/Emotional component:• Taking all things together, how would you say things are these days — would you say you are very happy, pretty happy, or not too happy?" Cognitive component:• "How satisfied are you with your life as a whole these days?"

Agonists and Antagonists

Agonists are substances that bind to synaptic receptors and increase the effect of the neurotransmitter. Antagonists also bind to synaptic receptors but they decrease the effect of the neurotransmitter.

What ways have been shown to improve IQ in children? (And what ways don't work?)

Anything you practice, you can get better at, IQ tests are designed with tasks that most people wouldn't practice In early childhood: - Nutrition found in breastmilk• - A year of training mothers to provide enriched cognitive environments - Interactive reading - Sending children to preschool In school-aged children: - Teaching children a musical instrument

Localization vs plasticity

Argument between people who think that the brian is one or the other. Neuroplasticity: Changes in the physical structure and functional organization of the brain due to experience - learning - re-mapping of sensory cortex - can occur after brain damage - can be positive or negative ex. Daniel Kish uses echolocation( sound) to navigate the world as a blind man Localization: the idea that certain functions have certain locations or areas within the brain. ex. seeing words, hearing words, reading words, and generating verbs

Binocular vs Monocular Depth cues

Binocular disparity - images giving slightly different info to each eye Monocular depth cues - depth cues that are able to be perceived without both eyes. ex. > Relative Height: Things at a distance look like their base is higher. > Relative Size: Objects farther away from other objects are smaller (Fig.

The stages of sleep and their associated brain waves

Stage 1 • Stage when first falling asleep (hypnagogia) . theta waves Stages 2 through 3/4 (slow-wave sleep) • light sleep •processing of memories • high-intensity brain waves • 55% of all sleep Stage 3 • sleep lightens • greater muscle relaxation - Delta waves - makeup 20-25% of sleep REM sleep • rapid eye movement • resemble beta waves • Brain waves similar to wakefulness • associated with dreaming

What do "system 1" and "system 2" describe?

System 1 Our intuitive decision-making system, which is typically fast, automatic, effortless, implicit, and emotional. System 2 Our more deliberative decision-making system, which is slower, conscious, effortful, explicit, and logical.

What is confirmation bias and what is motivated skepticism?

Confirmation bias favors information that is consistent with our beliefs We search for, attend to, remember, and use information that provides evidence for our beliefs. Motivated skepticism Shows that people are motivated to accept facts that are consistent with their desires/beliefs. Don't think too hard if it agrees with you• But if it disagrees with you, then work hard to disprove. ex. bringing people in take the paper in your mouth and dip it into the solution to see if it changes color if the paper doesn't change color and stays the same then you have the disease, but it never changes color and found that if you thought it was supposed to change or not then they would keep trying.

Conformity and the Asch Experiment•

Conformity- Changing one's attitude or behavior to match a perceived social norm. Asch Experiment: The tendency for a group to make decisions that are more extreme than the initial inclination of its members.

Know the difference between the moral theories of consequentialism and deontology

Consequentialism = a decision is morally correctif and only if it brings about better consequences. Deontology = a decision is morally correct if itadheres to principles (such as "do not harminnocent people")

Primary theories as to why we sleep

Conservation • Comparing energy use from sleep to wake shows that there is little gained Restoration • The body is recuperating at a genetic level Memory consolidation/neural synthesis • important connections are linked, strengthened • we do better at memory tasks when we "sleep on it" • we are more creative when rested

Encoding Specificity (e.g., context-dependent memory/Scuba Study)

Context-Dependent Memory - Physical location• e.g., studying in the same room as the exam is taken - Physiological Context • mood-dependent effects - State-dependent memory (e.g., learning/testing during alcohol intoxication) Scuba Study - divers were given 38 unrelated words (heard all words twice, through their scuba gear). - The words were given to them underwater vs on land • 24 hours later, they were then given a memory (recall) test, underwater or on land

Correlation vs. Causation

Correlation is the relationship between between two variables probability that the variables are closely related to one another. Causation the determination that one variable causes—is responsible for—an effect.

What sort of evidence would be needed to argue that something likeemotions are universal?

Cultural transmission - Expressions of other cultures seen on TV, movies, magazines, newspapers, direct contact - To get around the problems: Test a completely isolated culture ex. Papua, New Guinea study - pre-literate, hunter-gatherer culture - isolated from the West - no access to movies, television, literature - a limited chance for cross-cultural transmission - recognition of emotional faces would be stronger evidence of the universality

Know Piaget's stages of sensorimotor development (and their associated ages)

Four stages that Piaget hypothesized were the sensorimotor stage (birth to 2 years), the preoperational reasoning stage (2 to 6 or 7 years), the concrete operational reasoning stage (6 or 7 to 11 or 12 years), and the formal operational reasoning stage (11 or 12 years and throughout the rest of life).

What is the gambler's fallacy?

In a game of roulette, the ball has landed on"black" 7 times in a row. What are the chances that it will land on"black" again? When an individual believes that a certain random event is less likely or more likely to happen based on the outcome of a previous event or series of events.

Common sleep disorders

Insomnia Sleep Apnea Narcolepsy Sleep Paralysis Night Terrors REM Behavior Disorder (RBD)

Independent Variable (IV)

Manipulate something

The dependent variable

Measure the outcome

What is bounded rationality?

Model of human behavior that suggests that humans try to make rational decisions but are bound due to cognitive limitations.

How might you summarize the empirical findings on the relationship between money and happiness?

More money is associated with more happiness to an extent. INCOME Once your greater income happiness becomes constant, it reaches a plateau. Higher levels don't impact your life nearly as much as at the lower levels.

imaging methods

Neuroimaging tools are used to study the brain in action

Milgram experiment and what it was intended to show

People are highly influenced by authority - Our thoughts, feelings, and behaviors are shaped by the immediate social situation e.g., features of the environment can make good people more likely to do bad things Milgram obedience experiment - can also encourage people to do good things - can cause changes in attitudes

Peripheral Nervous System (PNS)

Peripheral divided into somatic and autonomic nervous systems Autonomic nervous: sensory information an involunterary muscles movement. Somatic nervous system: volitional actions

What does it mean to say that a study is "underpowered"?

Power: capacity to detect effects assuming they are there Many studies do not collect sufficient observations to detect the effects

Conservation problem

Problems pioneered by Piaget in which the physical transformation of an object or set of objects changes a perceptually salient dimension but not the quantity that is being asked about.

Memory Is The

Processing Of Information

Projective vs Objective tests

Projective Tests Reliable?• No.• Valid?• No. - have people interpret ambiguous stimuli as a window into their personality - Assumption: people will reveal hidden aspects of personality such as motives, wishes, and unconscious conflicts Objective Tests - Primarily questionnaire measures - Big 5 measures both reliable and valid - Stable over many years - Predicts real-world behavior

What is spontaneous recovery? (Recognize examples)•

Recovery of a response that occurs with time after extinction. > Can occur after extinction in either classical or instrumental conditioning. ex. For example, imagine you strongly associate the smell of chalkboards with school detention. Now one day, after entering a new building for the first time, you suddenly catch a whiff of a chalkboard, and WHAM!, the agony of detention returns.

replicability

Run the study again. - Allows you to examine if a finding isreliable - Replications can be tricky to interpret - Design differences - Underpowered failed replications - Replication successes that are inconsistent withoriginal

Psychology

Scientific study of mind and behavior

Structure of a Neuron (axon, dendrite, etc.)

Sensory (afferent) neurons, motor (efferent) neurons,interneurons • Characterized by all-or-nothing response

The Stages of Memory

Sensory Memory (like a "buffer") - Unattended information is quickly lost Short-term Memory (like RAM)/Working Memory - Unrehearsed information is quickly lost Long-term Memory (permanent(ish) storage) - Information is lost over time

What does "g" refer to in intelligence theory?

Short for "general factor" and is often used to be synonymous with intelligence itself. ex. G captures something basic about mental capacity (e.g., how efficient your brain is), or that IQ tests sample a lot of overlapping capacities(some tasks require memory + speed, others require speed + reasoning)

5. Taste Sensitivity Is Related To Political Orientaions

Some people have a higher density of papillae and some report it makes it bitter. The more papillae the denser and the more likely to be a super taster, likely to be more grossed out by things and conservative. The less grossed out more liberal.

Object Permanence

Task in which infants below about 9 months of age fail to search for an object that is removed from their sight and, if not allowed to search immediately for the object, act as if they do not know that it continues to exist.

The "Garcia Effect"—what it is and why it was an important demonstration.

Taste Aversion• - found that rats given sweetened water, then exposed to radiation (to induce nausea) - rats avoided the sweet water after only one trial organisms are biologically prepared to learn this association - conscious awareness is not necessary since sickness can occur hours later - only some kinds of stimuli work (pairing nausea with tones or lights has no effect)

Know the basic definition of empathy, and how we know psychopaths might not have it.

The ability to vicariously experience the emotions of another person. Psychopaths don't have the basic response of distress, people would don't have the basic response, of empathy. They don't seem to have that feeling when others are struggling. - Factor 1: "Aggressive narcissism" - Factor 2: "Socially deviant lifestyle" Psychopathy is an Emotional Deficit - Reduced skin conductance response (SCR) to distress and fear in others - Impaired startle response to threatening and distressing (mutilated bodies, victim being harmed) images - Abnormal conditioned fear response - Behaviorally uninhibited temperament• Reduced amygdala volume - They do not learn well from their mistakes

lexical hypothesis

The lexical hypothesis is the idea that the most important differences between people will be encoded in the language that we use to describe people. Therefore, if we want to know which personality traits are most important, we can look at the language that people use to describe themselves and others.

What are the most stable personality traits, and differentialvs absolute stability?

The most stable personality traits are extraversion and conscientiousness. Differential stability relative to others (rank order) vs Absolute Stability measured absolutely (e.g, actual score on a personality test)

What is hedonic adaptation?

We adapt to good and bad events with efficiency

What is diffusion of responsibility?•

When deciding whether to help a person in need, knowing that others could also assist relieves bystanders of some measure of personal responsibility, reducing the likelihood that bystanders will intervene. ex. courtyard murder/rape

Sensation

acquiring basic/raw information about theworld through the five senses

Convergence

at close distances, how much your eye is "crossed" gives the brain info about depth.

self report vs behavior

behavioral measures responses to uncommon stimuli in structured situation, whereas self-report measures ask participants to reflect on their behaviors across a variety of unstructured situations

Left and Right Hemispheres of the Brain

brain is divided into two halves Left Brain - resoning - language - right hand control Right Brain - creativity - left hand control

Central Nervous System (CNS)

divided into a number of important parts including the spinal cord 4 main parts: 1. Forebrain (Procencephalon) 2. Midbrain (Mesencephalon) 3. Hindbrain (Rhombencephalon) 4. Spinal Cord

p-hacking

exploiting researcher degrees of freedom to get significant results

Basic structures of the brain associated with psychological functioning

know the ones associated with perception and sensation. The parietal lobe is a cerebrum area just behind the central sulcus engaged with somatosensory and gustatory sensation. - sensations - language - perception - body awareness Occipital lobe- The back part of the cerebrum, which houses the visual areas. - vision - perception Frontal: movement, problem-solving, mood personality Temporal: learning, language, memory cerebrum: consists of left and right hemispheres that sit at the top of the nervous system and engage in various higher-order functions, and movements.

lab vs field

lab takes place in a laboratory environment under controlled conditions. Fieldwork is more random and spontaneous.

Primacy/Recency effects

learning new information, you are most likely to remember the things that you study first (the primacy effect) as well as those things you study last (the recency effect).

Fraud

making up or manipulating data - False positive psychology - Prevalence of questionableresearch practices

Positron emission tomography (PET)

measures brain activity by detecting the presence of a radioactive substance in the brain that is initially injected into the bloodstream and then pulled in by active brain tissue. - records blood flow in the brain.

Electroencephalography (EEG),

measures the electrical activity of the brain - greater temporal resolution (millisecond precision rather than seconds)

Three dimensions of methods

observation vs. experiment, lab vs field, self-report vs behavior

Observation vs. Experiment

observational designs provide good data but they cannot determine causality vs isolating variables in order to determine causality, Control vs. Experimental, Random assignment

4. Pain Caused Intentionally Feels More Painful

people were shocked at the same intensity revealing that more painful when people do it intentionally rather than unintentionally. - you can choose whether to deliver or give a shock and people didn't know if it was intentionally or unintentionally given

Computerized axial tomography (CAT) or MRI scanners

reveal high precision structures in the brain and can help detect changes in gray or white matter.

Negative Reinforcement

rewarding someone by removing a BAD thing (e.g., an umbrella stops the rain) (do not ever forget this, please.)•

What are display rules?

rules that are learned early in life that specify the management and modification of emotional expressions according to social circumstances. ex. Compared to Japanese and American students who were watching a film depicting a disgusting surgical procedure Japanese students were much less expressive (they maintained neutral expressions) than American students, but only when watching a film in the presence of an authority figure

What is scientific explanation?

satisfying explanation invokes a simple right-to-the-point question.

What is stimulus generalization?

stimuli that are similar to the conditioned stimuli will predictably cause the conditioned response. The more dissimilar the less likely it will cause the conditioned response.

Falsifiability

the ability of a claim to be tested and—possibly—refuted

What is the average IQ, and what does the distribution look like? (e.g., what percent fall into +/- 1 Standard Deviation?)•

the average IQ is 100, normal bell curve distribution. 1 standerad deviation is 15 points in IQ.

Dunning Kruger effect

the less you know about a domain, the easier it is to be bad at estimating how good you are

Transduction

turning sensations into what the brain can use, the conversion of one form of energy into another. - Brain transduces incoming information (e.g., light waves, soundwaves, particles)

Punishment

you all know this one—negative consequences in response to an unwanted behavior.

Anal Stage (1 - 3 Years)

• Anus is associated with pleasure • Toilet training can lead to fixation if not handled correctly • can lead to retentive or expulsive behaviors in adulthood, or a personality: compulsiveness

REM Behavior Disorder (RBD)

• Disorder in which people act out their dreams

What happens during REM sleep?

• EEG patterns that resemble beta waves of alert wakefulness • Muscles most relaxed • Rapid eye movements occur • Dreams occur • Four or five sleep cycles occur in a typical night's sleep

Night Terrors

• abrupt awakenings with panic and intense emotional arousal • occurring during slow-wave sleep Somnambulism (sleepwalking) • non-REM parasomnia (2-14% of children)

Insomnia

• difficulty in falling or staying asleep

Oral Stage (Birth - 1 Year)

• mouth associated with sexual pleasure • Weaning a child can lead to fixation if not correctly • can lead to personality passivity, gullibility, immaturity, and unrealistic optimism.

Sleep Apnea

• person stops breathing for brief periods while asleep

Narcolepsy

• sudden sleep attacks occur in the middle of waking activities

Sleep Paralysis

• the experience of waking up unable to move

p- hacking example

Does Psych 1101 make students happier? • 2 groups: psych 1101 vs. control class(oceanography)• Outcome: ratings of happiness • Researcher degrees of freedom: - When do we end data collection? - Do we exclude students who did not attend xnumber of classes? - Which questions do we use to measure happiness? - Do we "control for" baseline levels of happiness?

Which nations are lower/higher in happiness/life satisfaction and what might be the causes?

Higher happiness in wealthier northern countries. Most of those with low-income report to be the least happy. However, some of the poorest countries report higher levels of happiness. Causes: some people are just happier people and life events influence happiness. ex - Accident-caused paralysis - Lottery winners - Professors getting or not getting tenure - Breaking-up

Explicit vs Implicit attitudes (and how implicit have been measured)•

Implicit Attitude: An attitude that a person cannot verbally or overtly state. Explicit Attitude: An attitude that is consciously held and can be reported on by the person holding the attitude.

Pre-Registration

Data analysis plan posted before they are analyzed

Primary neurotransmitters and their functions (incl. how certain drugs act by increasing or decreasing these)

GABA (gamma-aminobutyric acid) - main inhibitory neurotransmitter in the brain (low GABA linked to generalized anxiety disorder) Endorphins - relief from pain or the stress of vigorous exercise and produce feelings of pleasure and well-being (responsible for pleasure of sex/orgasm, eating appetizing foods, etc.). Acetylcholine - stimulates muscle movement, memory, arousal, attention, mood Norepinephrine/noradrenaline - affects eating habits - major role in alertness and wakefulness, fight-or-flight Dopamine - called monoamines, produces both excitatory and inhibitory effects - several functions: learning, attention, and movement - gives you the feeling of reward through pleasure and addiction ex. cocaine and amphetamines act by boosting dopamine. Too much dopamine-boosting and you'll get amphetamine psychosis. Serotonin - important in regulating mood, sleep, impulsivity, aggression, and appetite

How heritable is IQ?

Genetics contribute to everything including genetics. Heritability doesn't tell us a person's intelligence is due to genes vs environment or anything about which genes cause a trait. ex. to find heritability compute the correlation between the IQ (or any trait) of identical twin siblings (who share, roughly, 100% of their DNA) Then the correlation between the IQ of fraternal twin siblings (who share the same DNA as other non-twin siblings share).• Assumption: both children are raised by the same parents, in the same environment. Differences seen should be genetic differences.

What are heuristics, and what is their relationship tobiases? (Know anchoring and framing)

Heuristics—mental shortcuts that serve as guides to making judgments and decisions without having to go through all that calculation, biases are created by the tendency to short-circuit a rational decision process by relying on a number of simplifying strategies: Framing The bias is systematically affected by how information is presented while holding the objective information constant. Anchoring The bias to be affected by an initial anchor, even if the anchor is arbitrary, and to insufficiently adjust our judgments away from that anchor

Know the big 5 personality traits (OCEAN) and their basic descriptions

Openness to experience: reflects a person's tendency to seek out and appreciate new things, including thoughts, feelings, values, and experiences. - imaginative vs. down-to-earth - like vareity vs. likes routiine - Independent vs. conforming Conscientiousness: reflects a person's tendency to be careful, organized, hardworking, and to follow rules. - organized vs. disorganized - careful and careless - self -disciplined vs. weak-willed Extraversion (also often spelled extroversion): reflects a person's tendency to be sociable, outgoing, active, and assertive. - social vs. retiring - funloving vs. sober - affectionate vs. reserved Agreeableness: reflects a person's tendency to be compassionate, cooperative, warm, and caring to others. People low in agreeableness tend to be rude, and hostile, and to pursue their interests over those of others. - Softhearted vs. ruthless - trusting vs. suspicious - Helpful vs. uncooperative Neuroticism: reflects the tendency to be interpersonally sensitive and the tendency to experience negative emotions like anxiety, fear, sadness, and anger. - Worried vs. calm - insecure vs. secure - Self-pitying vs. self satisfied

Freud's stages of psychosexual development (and associated ages)

Oral Stage (Birth - 1 Year) Anal Stage (1 - 3 Years) Phallic Stage (3 - 5 Years) Latency Stage (5 - Puberty) Genital Stage (Puberty On)

What is the Flynn effect, and why wasn't it obvious for awhile?

The effect demonstrates that overtime people seem to be getting smarter. Flint found that the raw score improves over time. This could be attributed to nutrition, low environmental pollution, and education.

What is Inattentive Blindness?

The failure to notice a fully visible, but unexpected, object or event when attention is devoted to something else. ex. the cocktail party effect: hearing background chatter all over the place at a party but you are not attending to those conversations, but every once in a while you hear your name

Phallic Stage (3 - 5 Years)(Oedipus Complex)

• Focus of pleasure shifts to the genitals • Oedipus complex (boys) or Electra complex (girls)occurs at this stage • can lead to excessive masculinity in males and the need for attention or domination in females

Freud's three part structure of the mind (and how each isdescribed)

• Id - "dumb," driven by instinct, present from birth - can't distinguish reality vs. fantasy -operates according to the pleasure principle - unconscious mind • Ego develops out of the id in infancy -understands reality and logic -mediator between id and superego - conscious mind • Superego -internalization of society's moral standards -responsible for guilt - unconscious mind

Why do researchers think that there is evidence for the universality of some emotional expressions?

• Observe it across a wide variety of cultures • Observe it early in life • Observe it across species, especially close evolutionary relatives • Demonstrate that it does not require a lot of learning/input ex. Emotional Expression Studies - people from: the U.S., England, Germany, Sweden, France, Switzerland, Greece, Japan, and Mexico •Collect photos of emotional expressions •Show photos to subjects • asked to match a photo to emotional term

Genital Stage (Puberty On)

• Sexual feelings re-emerge and are oriented toward others • Sexuality is consensual and adult, rather than solitary and infantile •Healthy adults find pleasure in love and work •Fixated adults have their energy tied up in earlier stages

Latency Stage (5 - Puberty)

• Sexuality is repressed • Children participate in hobbies, school, and same-sex friendships, and derive pleasure from those
