Ap psych final study guide People we should know ● Kohlberg: 6 stages of Moral development (Preconventional, Conventional, Postconventional) ● Erikson: Stages of Social Development (stuff like trust vs mistrust, etc etc.- there's an entire packet on him, she had us start the ones that were significant) ● Ainsworth: did studies on attachment ● Gilligan: did research on differences between men and women and their moral judgment ● Harlow: Monkey attachment experiment: one with food and wire, one with cloth, monkey went to cloth one and only went to wire one for food occasionally, showed they preferred comfort ● B.F Skinner: Operant Conditioning: did thing with the chamber, food maze and rat thing ● Piaget: 4 stages of cognitive development, SPCF (Socks Pull over Cold Feet), Sensorimotor, Preoperational, Concrete, Formal ● Pavlov: Classical Conditioning, experiment w the food+dog+tone (think lemonade experiment) ● Bandura: Observational Learning (did the Bobo the clown experiment where they showed children aggressive videos and then put them in a room with a clown and a bunch of toys, every single kid beat up the clown in a really aggressive way, shows that they learned thru observation) prologue + CHAPTER 1 ● ● ● ● Psychology: the scientific study of behavior and mental processes Positive Correlation: as one thing increases, the other increases Negative Correlation: as one thing increases, the other decreases The three central tendencies: MEAN, MEDIAN, AND MODE ○ Mean: the average of the whole group ○ Median: middle score in the whole group ○ Mode: # that shows up the most ● The three measures of Variance: RANGE, VARIATION, STANDARD DEVIATION ○ Range: difference between highest and lowest scores ○ Variation: score - mean = variance ○ Standard Deviation: avg diff between scores and their means; the square root of variance ■ Must fall between 0 and half the range ● Correlation Coefficient: represents the strength of a relationship between 2 values ○ + - 1, closer it is to POSITIVE or NEG- 0 MEANS NO CORRELATION ● CORRELATION DOES NOT MEAN CAUSATION ● Double- Blind Experiments: used to eliminate experimental bias, both the subject n doctor or whoever person are unaware of whether or not the person is receiving the placebo or the actual thing *think clinical trial, both patient and his doctor don’t know if he's receiving a placebo or actual chemo, this is done so Dr. has no bias towards any of his clinical trial patients ● Statistically Significant: the likelihood that the results you're seeing were NOT by chance ○ Probability has 2 be less than or equal to .05 but scientists want closer to .01 ● Random Sampling: how I get my participants, picking people from the population ● Random Assignment: by chance, you randomly assign ppl to the control group or experimental group; helps avoid confounding variables ● Overconfidence: ● Hindsight Bias: “I knew it all along!!” after something happens u claim that you knew it all along, saw it coming, blah blah ● Confirmation Bias: people tend to only look at information that supports or confirms their idea/opinion, don't want to look at anything that opposes it ● Illusory correlation: when u perceive a relationship where there highkey isn't one, ex: thinks every time she gets a car wash it rains the next day Chapter 2A: Neurons Neurotransmitters Chapter 2B: Brain Hindbrain ● Medulla - controls breathing and heartbeat, regulates reflexes (i.e. sneezing, coughing, salivating) ● Pons - involved in sleep arousal, connects spinal cord with the brain and links parts of the brain to one another ● Cerebellum - assists in balance and coordination of voluntary movement, coordinates fine muscle movement and balance Actual commands for muscular movement come from higher brain centers - cerebellum organizes the sensory information that guides these movements Midbrain - Relays sensory information from the spinal cord to the forebrain ● Reticular Formation - maintains a state of arousal, arouses the cerebral cortex to new stimuli (runs through hindbrain and midbrain) Forebrain ● Limbic System - involved in emotions, memory and basic psychological drives ○ Thalamus - relays/routes incoming messages/sensory information to the appropriate cortex and transmits replies to the medulla and cerebellum ○ Hypothalamus - Regulates hunger, thirst, body temp, sex ○ Hippocampus - involved in learning and formation of memories ○ Amygdala - influences/associated with/involved in emotions and fears ● Cerebrum - regulates higher cognitive and emotional functions (i.e. learning, remembering, thinking) ● Cerebral Cortex - seat of information processing (bark of the brain) Frontal Lobes - involved in speaking, muscle movement, and decision making ● Prefrontal Cortex - the CEO of the brain, monitors planning complex cognitive behavior, decision making, and moderates/restrains social behavior ● Motor Cortex - controls voluntary movement ● Broca’s Area - involved in controlling the motor ability needed to produce speech Parietal Lobes ● Sensory Cortex - regulates and processes body sensations - pressure, touch Occipital Lobes ● Visual Cortex - receives/processes information from the eyes Temporal Lobes - receives/processes information from the eyes ● Auditory Cortex - receives and processes auditory information ● Wernicke’s Area - involved in language comprehension Associated Areas ● Located throughout the cerebral cortex, involved in mental functions (i.e. - learning, remembering, abstract thinking), supports abstract thinking and language integrate information from different receptors or sensory areas Endocrine: - secrete hormones into the bloodstream Adrenal glands - a pair of endocrine glands that sit just above the kidneys and secrete hormones that help arouse the body in times of stress Pituitary glands - the endocrine system’s most influential gland. Under the influence of the hypothalamus, the pituitary regulates growth and controls other endocrine glands Chapter 4&5: Personality and Development Nature vs. Nurture ● Genes vs. environment Philosophers Nature Nurture Plato Aristotle Descarte Locke mind is blank slate on which experience writes Milestones Wundt Founding father, did the first laboratory in Germany; taught scientific method Tichner Structuralism: structures make up the mind Darwin Natural selection guy James FATHER OF PSYCH; functionalism Infant Behavior ● Rooting Reflex - A reflex that automatically causes the baby to turn their face to the stimulus and make sucking motions when the lip or cheek is touched ● Imprinting - in young animals the ability to recognize something with habitual trust ● Infantile amnesia - the inability to remember back to before our third birthday Prenatal ● Teratogens - agents, such as chemicals and viruses, that can reach the embryo or fetus during prenatal development and cause harm ● Fetal Alcohol System - physical and cognitive abnormalities in children caused by a pregnant woman’s heavy drinking. In severe cases, symptoms include noticeable facial misproportions. ● Harlow’s studies on attachment - MONKEYS ○ Preferred the comfort of the cloth over the nourishment from the food ● Development ○ Zygote - fertilized egg; it enters a 2-week period of rapid cell division and develops into an embryo ○ Embryo - the developing human organism from about 2 weeks after fertilization through the second month ○ Fetus - the developing human organism from 9 weeks after conception to birth Schema - concept or framework that organizes and interprets information (FILE CABINET) ○ Accommodation - adapting our current understandings to incorporate new information ○ Assimilation - interpreting our new experiences in terms of our existing schemas Child Rearing Practices Authoritative Parents impose rules and expect obedience Permissive Parents submit to their children’s desires Authoritative Parents are both demanding and responsive Development Kohlberg Stages of Moral Development Level I. Preconventional Morality Stage 1 Punishment Orientation A person complies w rules during this stage in order to avoid punishment Stage 2 Reward Orientation An action is determined by one’s own needs Level II. Conventional Morality Stage 3 Good-girl/Good-boy Orientation Good behavior is that which pleases others and gets their approval Stage 4 Authority Orientation Emphasis is on upholding the law, order, and authority and doing one’s duty by following societal rules Level III. Postconventional Morality Stage 5 Social Contract Orientation Flexible understanding that people obey rules because they are necessary for the social order but that rules can change if there are good reasons and better alternatives Stage 6 Morality of Individual Principles orientation Behavior is directed by self-chosen ethical principles. High value is placed on justice, dignity, and equality Piaget Stages of Cognitive Development Sensorimotor Object Permanence Stranger Anxiety Preoperational Egocentrism Concrete Operational Conservation of Mass Formal Operational Abstract Reasoning Erikson (Eight) Stages of Psychosocial Development Trust vs. Mistrust - Infancy Ages: 0-1 ½ Develops sense of trust when interactions provide reliability, care, and affection Basic Virtue: Hope Autonomy vs. Shame & Doubt Ages: 1 ½ - 3 Develops a sense of personal control over physical skills and a sense of independent Basic Virtue: Will Initiative vs. Guilt Ages: 3-5 Begins to assert control and power over their environment by planning activities, accomplishing, accomplishing tasks & facing challenges Basic Virtue: Purpose Industry vs. Inferiority Ages: 6-12 The child’s peer group will gain greater significance & will become a major source of child’s self-esteem Basic Virtue: Competency Identity vs. Role Confusion - Adolescence Ages: 12-18 Teens explore who they are as individuals, and seek to establish a sense of self, and may experiment w/ different roles, activities, & behaviors Basic Virtue: Fidelity Intimacy vs. Isolation - Young Adulthood Ages: 18-40 Seeking love or affection to avoid loneliness Basic Virtue: Love Generativity vs. Stagnation Ages: 40-65 Am I successful? Am I a productive member of society? Basic Virtue: Care Integrity vs. Despair - Late Adulthood Ages: 65+ Reflection of your life. Did I lead a good life? Basic Virtue: Wisdom Chapter 6: Sensation and Perception ● Sensation: detectable input from environment; perception: understand and interpret da info ● Absolute Threshold: minimum amount of stimulation needed to detect it 50% of the time ● JND: Just noticeable difference: smallest amt of change needed between 2 stimuli that I can detect 50% of the time ● Parts of the eye: ○ Rods: receptors for black and white; night vision ○ Cones: receptors for color; daylight ○ Blind spot: the spot where the optic nerve leaves the eye ○ Optic nerve: impulses to the brain from the retina at the back of the eye. ● Ear stuff: ○ Middle ear- small bones: hammer, anvil, stirrup; transmits sound ○ Inner Ear: transduction takes place here but like mainly in the cochlea-sound waves into neural energy oval window, cochlea, semicircular canals, auditory nerve, basilar window ○ Outer ear: gather the sound, pinna, ear drum, ear canal ● Gate control: gates open to release pain-open during painful experience ● Sensory adaptation: adapting to the senses, helps u like not focus on irrelevant stimulus ● Sensory interaction: all the senses work together ● Opponent processing - created by Edward Hering; alternative theory used to explain after images; suggest that the retina contains three pairs color receptors or cones-yellow-blue, red-green, black-white; pairs work in opposition ● Young-Helmholtz - respond to green, blue, red problem it doesn't explain color blindness or after images , otherwise known as the trichromatic color vision theory ● Pitch determination/detection: ○ PLACE THEORY: explains how we hear high pitched sounds but not low pitched sounds ○ Frequency theory: explains low pitched not high pitched ○ Volley: both r correct ● Smell, taste, equilibrium, kinesthesis, vestibular ● Gestalt: whole, form ● Figure ground relationship, proximity, similarity, continuity, closure, connectedness ● Monocular cues: relative size, relative height, texture gradient, relative gradient motion ● Binocular cues: retinal disparity and convergence ● Parapsychology: ESP stuff, scientists have proven this 2 be false; telepathy, clairvoyance, precognition ● Top-down: start with info or knowledge (like in class of the puzzle) and work our way down ● Bottom-up processing: starting with the stimulus and from there u break it down and analyze dat ish (putting a puzzle together, starting w the individual pieces n working YO WAY UP) ● TRANSDUCTION EYE: RETINA ● TRANSDUCTION EAR: COCHLEA- BASILAR MEMBRANE/WINDOW ● Weber’s Law: AMT of change needed in order to recognize a difference, it b proportional ● Types of da hearing loss: conduction hearing loss: something goes wrong w da cochlea, stirrup deteriorates but can be fixed w da surgery ○ Sensorineural: nerve deafness- from loud noises, no treatment ● Perceptual constancy, perceptual set: things stay constant even tho da size b changin Chapter 7: Learning ● Classical Conditioning: Pavlov experiment with the dogs, tone, and meat ○ NS: irrelevant stimulus, elicits no reaction but paired w/ US *pavlov ○ US: elicits a natural, unlearned + reflexive response * lemonade ○ CS: learned stimulus produces CR *pavlov ○ UR: unlearned, AUTOMATIC response *salivating ○ CR: learned response * salivating ● Acquisition: the initial stage where the NS becomes the CS and the UR becomes the CR; UNCONDITIONED BECOMES UNLEARNED ● Extinction: diminished responding when the CS no longer signals the US (not salivating to Pavlov anymore) ● Discrimination: learned ability to distinguish between your learned stimulus + other similar ● Generalization: once a response has been conditioned, stimuli similar to it can elicit the same response ● Operant Conditioning- My man SKINNER voluntary behavior is strengthened if it is reinforced or weakened if it is punished - RESPONSE IS CONTROLLED BY CONSEQUENCE ○ Positive reinforcement: adding something good that increases the likelihood that a behavior will reoccur ○ Negative Reinforcement: take away something bad that increases the likelihood that a behavior will reoccur ● Skinner Box and shaping: shaping = rewarding closer and closer approximations to desired behaviors ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ○ Primary reinforcer: reinforcer that helps w like a biological need, such as foodtaking advil ○ Secondary Reinforcer: something that supports the primary reinforcer *** ○ Spontaneous Recovery: randomly spontaneously the CS starts signaling the US again *we start salivating to Pavlov Positive punishment: add something bad which decreases likelihood that behavior will reoccur Negative Reinforcement: take away something good which decreases likelihood behavior will reoccur Latent Learning: a skill that only appears when you’re doing it for reward; im good at reading but i only read if i get something out of it---like in middle school typa thing Cognitive Maps: a mental image of something in one’s environment: know ur way about school, knowing the map of ur house without having to draw it out Overjustification: effect of promising a reward for something someone already likes to do Intrinsic motivation: me myself N i Extrinsic Motivation: doing for whatever that reward might be Chaining: a subject is taught to perform a # of responses successfully in order to get a reward *chain link Modeling: Latent Learning: nonreinforced learning that is not immediately reflected in our behavior Schedules ○ Continuous: REINFORCED every time a behavior occurs; works faster ○ Partial: REINFORCED only some of the time; less likely 4 extinction Fixed Ratio: rewarded after a set # of behaviors/responses Variable Ratio: reinforcer given after changing, random, or unpredictable # of times *slot machines *BEST ONE Fixed Interval: fixed amt of time has to pass Variable Interval: behaviors reinforced after a variable time has passed ● Observational Learning: BOBO DA CLOWN + BANDURA = ANGRY KIDS Chapter 8: Memory ● Three steps of information processing: ○ Encoding (Acoustic, Visual, Semantic) ■ Acoustic: Echoic Memory- lasts longer than Visual memory ■ Visual: Iconic Memory ■ Semantic: facts and stuff ○ Storage: ■ Short-term: activated memory that can hold 7 items +-2 (5-9 #s) briefly before info stored or forgotten; usually can’t hold it for more than 30 seconds ■ Long-term ■ Hippocampus: temporal lobe neural center that serves as sort of a “save” explicit memories ● Damage: disrupts recall of explicit memories ○ Left: Verbal ○ Right: Visual ○ Retrieval: ■ Interference: Proactive- previous info getting in the way of recent; Retroactive: recent info getting in the way of old information ○ Repression: forceful forgetting of information that may be emotional, sad, or painful to relieve ● ● ● ● ○ Ebbinghaus’ Curve: he’s like the genius guy of memory, he proved that you can’t over learn anything, and that its important u space studying out Flashbulb Memories: very vivid memories of emotional times- a family member passing, where you were on 9/11, you can almost put yourself back into that moment Spacing Effect: spacing out your studying is better, you’ll remember it more Serial position: U remember better the first and last things you learn or on a list ○ Primacy = first, recency = last *experiment with freshmen memory Mnemonic: helpful ways to remember stuff, study tools ○ Peg word: you use specific words to remember concepts, like the experiment in class w libby, gabe, trystan where its like one is tree, two is green, blah blah blah, and the peg words help you remember ○ Method of loci: greek method used to remember speeches, it uses visualization ○ Acronyms: PSCF - pull socks over cold feet, preop, sensorimotor, concrete, formal ○ Mood congruent: ur mood matches ur mems, if ur sad you'll think about sad memories ○ Context memory: scuba diver experiment thing, when ur tested in the same context u remember it more easily ○ State-dependent memory: u remember stuff more easily in the state u were in (hide something when ur drunk, remember where it is when ur drunk) ○ REtrograde amnesia: cant remember stuff from before onset of amnesia ○ ANTEROGRADE AMNESIA: cant remember stuff from after onset of amnesia Chapter 9: Intelligence ● Thinking: ○ Concepts: mental groupings of similar events and things (ex: Flowers) ○ Prototype: the best example for that concept (Ex: the prototype for flowers would be a Rose) ○ Heuristics: logical ways to solving problems; 2 types ■ Availability Heuristic: base your thinking off of all the information that is AVAILABLE to u, everything that you know, this has a lot to do with the media-- you think that planes are dangerous because all u see in media is plane crashes, not successful plane flights ■ Representativeness Heuristic: based on your prototype, everything has to fit your prototype or best example for your concept ○ Framing of questions: they way you word a question greatly impacts the responses, you can frame a question a specific way to elicit a specific response ● Problem Solving: ○ Techniques: ■ Heuristics: logical rule of thumb strategies to come to a solution (Ex: trying to figure out someones password, guess logical things for that specific person like their birthday, their initials, a significant date u know) ■ Algorithm: an actual step by step procedure, takes really long because you're trying every single possible outcome ○ Obstacles: ■ Fixation: when you try something and it doesn't work, but you get stuck on it (fixated) and keep trying it ■ Confirmation Bias: *from prologue and chapter 1* only look at ideas that support your belief, never look at the opposing side ■ Belief Perseverance: you stick with your ideas and beliefs even if you are presented with evidence and info that clearly shows that your idea is false ● Language Acquisition: ○ Chomsky and Skinner (Nature vs Nurture): ■ Chomsky believed in Nature, that we’re all born w a “language acquisition device” that requires us to learn language in a specific way during their critical period ● “Kids all go thru stages of learning language and all around the same time” ■ Skinner - Nurture: believed language was a learned skill ● Bandura agreed, we can remember this by remembering that these 2 were in chapter 7, learning, and they think LANG = LEARNED ○ Phonemes: smallest unit of sound ○ Morphemes: smallest unit of meaningful*** sound (like -ed, ing, etc) ○ Semantics: set of rules for how we derive words ○ Syntax: the arrangement of words and phrases to create well-formed sentences in a language
