Came up with tabula rasa: we are all born the same and through conditioning we are who we are
Little albert experiment Felt that psych should only focus on behavior
John B. Watson
Aversive conditioning (conditioning for negative response)
Little albert experiment (11 months) Associates mouth with painful experience UCS-loud noise UCR-fear CS-rat CR-fear of rat
John Watson: Aversive conditioning
Second order or higher order conditioning Once a CS elicits a CR, the CS can be used
(as US) to condition a response to a new stimulus
Ex: dogs salivate to bell (first order conditioning)
Light is paired with bell (second order) Light-salivation
Second order conditioning
Animals/ humans are biologically wired to make certain association more easily than other
Ex: Conditioned (learned) taste aversions (adaptive
response)-Fudge: shaped in squares and dog feces-Bottle: labeled sucrose and cyanide-Classical conditioning, but biologically
predisposed
Biology and classical conditioning
Learning based on consequences-association made between consequences and ones behavior Thorndike’s law of effect-positive consequences result in strong stimuli response connectionNegative consequences results in weakened stimulus response connection-decreased behaviorInstrumental learning: consequence shapes behaviors
Operant conditioning
Classical-stimuli Operant-consequences
Classical vs operant conditioning
Felt that external influences not internal thought feeling influence behavior
Something that you can test not unconscious What can lead to certain behavior Operant conditioning Most influential individual in the field
B.F. Skinner
Testing rewards and punishment Experiment on rats
The skinner box
Reinforcement: a consequence that encourages a certain behavior
Positive (+) reinforcement: add something pleasant (treat for a dog)
Negative reinforcement (-) : remove something unpleasant (take Advil to remove headache)
Negative punishment (omission training): removes something pleasant (being grounded)
Positive punishment: adds something negative (hitting dog with newspaper)
Skinner’s reinforcement
Shaping:-reinforcing the steps used to reach a desired behavior (single behaviors-press bar for food) Chaining:-reinforcing a number of separate behaviors for a more complex activity (obstacle course, salsa lessons)
Learning by Operant Conditioning
Primary reinforces-natural reinforces (food, water) Secondary reinforces-things we’ve learned to value: (money)
Types of Reinforces
money= generalize reinforce-can be used for anything Token economy-tokens as a positive reinforcement-cash in for other reinforces-schools, mental institutions, prisons
MONEY AS A REINFORCES
Reinforces: effects can vary-effect of reinforce can vary depending on animal, its instincts, and situation
instinctive drift: -ignore rewards to follow natural (instinctive) behavior Premark Principle-if two activities-the one preferred can be used to reinforce the one not preferred
Biology and operant conditioning
Reinforcement schedules=pattern of reinforcing behavior
Administered in 2 ways: Ratio-number of responses Interval-time
Reinforcement shedules
FR (fixed ratio): reinforcement after set number of responses
VR (variable ratio): reinforcement after varied number of responses -lottery
FI( fixed interval): fixed amount of time set before reward behavior-every 2 weeks get a paycheck
VI(variable interval): varied amount of time before reward (avg time set)-pop quiz
Reinforcement schedules
FR and FI=faster acquisition (learning), but faster extinction
VR and VI: slower learning but slower extinction
Which of these four yields the highest rate of response?
Why slower extinction with VR and VI?-noticing a break in pattern is more difficult - “always that chance”
Learning and extinction
Escape learning-to terminate an aversive stimulus: ex-to disrupt English class as to “get out” Avoidance learning -to avoid stimulus all together: ex-cut English class
There is a student that disruptive in class and gets kicked out, he doesn’t want to be in class anyways
so getting kicked is what motivates him to keep doing it
Learning with punishment
According to behaviorists, what are potential pitfalls of punishment
-tells only what NOT to do, not what to do-creates anxiety which interferes with learning-only suppresses behavior, doesn’t eliminate (discrimination)-Physical punishment-aggressive behavior (correlation, not causation)
Pitfalls of punishment
Similar-both forms of associate learning-both involve: acquisition, extinction, spontaneous recovery, generalization, discrimination-both influenced by biology and cognition Differences-classical: response is automatic, reward independent of action, learning is part of the autonomic response (UCR)-operant: response is voluntary, reward contingent on action, learning is part of voluntary behavior
Classical vs operant
PAVLOV-classical conditioning-how all organism learn to adapt to their environment-practical applications for fears, phobias etc. Skinner-definitive insight into learned behavior-practical applications abound Both asserted that learning occurs w/o though
(cognition) Only focused on observable behavior
How could cognitive argue that cognition is influential in both classical and operant conditioning
-classical: CS triggers anticipation of UCS -operant: awareness that
responses=consequences and thus acts to max the reinforcement
Cognitive learning
Observational learning-aka modeling-observation=imitation-mirror neurons (frontal lobe/neural basis for observational learning)-Albert Banduras: Bobo doll experiment social learning theory (species specific) antisocial BEHAVIOR (Bobo doll experiment: two dolls in diff rooms, one acted upon aggression other nice, see response in students ) Implications for TV and youth?
Cognitive learning
Latent learning (“hidden”) Learning that is not directly observable Tolman’s Rat maze study-group 1: rewarded every time reached goal-group 2: no reward when reached goal-group 3: no reward 1st 10 days, reward on 11th
finding: Latent learning (3rd group learned cognitive map in 1st trial, bur didn’t show it until reward)
thus learning takes place without reinforcement
Cognitive learning
Insight learning (aha!) Sudden grasp of problem Wolfgang Kohler: Chimpanzees Sudden insight, not gradual strengthening od
S-R association
Cognitive Learning
Cognition
Encoding: processing of info into memory system (typing on a computer)
Storage: retention of encoded material over time (to hit save)
Retrieval: getting the info out of storage (opening a file)
Memory process 3 steps
Sensory memory: held for a few sec according to the sensory impact on our organs (glow sticks)
Short-term memory (working memory) Long-term memory
The stage processing model
Immediate recording of sensory info “Split sec holding tank” Most stimulus no encoded
-selective attention: only pay attention to certain things Sensory memory registered as:-iconic (split sec vanishing picture)-echoic (4 sec sounds)
Sensory memory
Memory that holds a few items briefly Limit: seven digits/ items (plus or minus 2) Info is stored into long-term, or forgotten Lasts 3-12 sec
Shirt term, or working memory has 3 parts:-acoustics codes: encoding sound-visual codes: how you see the letters-semantic codes: meaning
Short term memory (working memory)
Permanent and limitless storehouse of the memory system
Long term memory
An extreme emotional moment or event Somehow branded into long-term memory
Where were you when?-you heard about 9/11-your first kiss-first car accident
Flashbulb memory
2 ways:-automatic processing-effortful processing
Encoding
Automatic:-unconscious encoding-location, time and frequency-retracing steps to find your keys-also becomes automatic with practice
Encoding
Effortful processing-attention/ conscious effort-studying for a test-through practice effortful can become automatic
Encoding
Spacing effect-encode info better if in increments over time
Serial positioning effect -tendency to recall best the first and last items in a list -primary effect: remember 1st words, items -regency effect: remember last items, words Next-in-line effect -don’t remember what someone has said if we are next.. Self-reference effect -we encode better when issue relates to us
Factors that influence
Mnemonic devices Any learning technique that aids memory
-uses imagery, semantics to remember…
Acronyms: Parentheses, exponents, multiplication,
division, addition, subtraction “Please excuse my dear aunt Sally”
Encoding strategiesCan enhance memory …
Last usually between 3 to 12 seconds Limit: 7 (plus or minus 2) chunks of info We recall digits better than letters .
Storage and short- term memory
Remember: there is no one single compartment for memory in our brain
Long term-potentiation-leading theory for LTM (long term memories)-neural networks strengthen memory-neural connections gradually strengthen through rehearsal over time (memory strengthened) -nerve cell’s genes produce synapse strengthening proteins/ enabling LTM formation
Critical memory (injury=impairment) -left=vertical memory -right= visual/location Processes LTM, then stores elsewhere in
cerebral cortex Ex: if library=our brain,
librarian=hippocampus
Hippocampus
Emotional memories -images, smells, sounds Hippocampus and amygdala work
together to form LTM -hippo=conscious memory of event -amygdala=emotional memory form the senses
Amygdala
Recognition; multiple choice Recall; long response
Retrieval recall vs recognition
Memory = web of associations Priming “strand or web of associations that
leads to a specific memory”
Retrieval cues
Context effect-retrieval is more effective when retrieving in some location as experienced Tip of the tongue effect(TOT)-temporary inability to retrieve specific names of info -usually remedied by semantic cues
Factors that influence retrieval
Mood-congruent theory-the tendency to recall memories consistent with our current mood State - dependent theory-recalling events encoded while in a particular state of consciousness-ex: if you hide money while you are drunk, you are most likely to remember where you hid it when you are intoxicated
Conditions that affect memory
Encoding failure Storage decay Retrieval failure
3 ways we forget
Don’t encode what we don’t need Not encoding/ no LTM
Encoding
Memory storage decays over time Lack of rehearsal accelerates decay Ebbinghaus’s forgetting curve-step decline of retention over 1st 3 days, then levels off…
Storage decay
2 TYPES:
Proactive interference-new info is messed up by the old info-pro=new
Retroactive interference-old info is messed up by new learning-retro=old
Retrieval failure
REPRESSION: Psychoanalytic theory-Freud’s theory of
repression -we push away uncomfortable memories -contradicts theory that emotions/stress hormones strengthen memories
Retrieval failure
Memories bend and change over time, and are often inaccurate!!
Youngest and oldest (5-75) are most susceptible -frontal lobe: matures slowly and decays quickly Research studies Elizabeth Loftus (over 200 experiments)-how wording influences our memory Cornell University-Space Shuttle Disaster-recollections on day after and 3 years later-2/3 were totally wrong as to whom with, where etc.
Research studies
About how fast were the vehicles going where they slammed into each other
OR When they ran into each other?
Misinformation effect
Forgetting source of a memory Where did they hear that? One of the frailest parts of our memory
Amnesia
Anterograde -remember everything before the accident, but not after (50 first dates) Retrograde Amnesia-remember everything after the incident, but not before (the vow)
Types of amnesia
Cognition Concept Category hierarchies
We from concepts by…-definition-prototypes: dog-first kind of dog that pops into your head
Organizing our thoughts(making cognitive sense out of our world)
Cognitive problem solving-algorithms: always leads to right answer -heuristics: saves you time, shortcut-insight:
Problem solving with cognition
Heuristic problem solving: hugely useful, but sometimes leads us astray..
Availability heuristic: how we tend to judge things what we are exposed the most (why we develop fears of airplanes, than driving cars)
Representative heuristic:
Limitations of heuristic judgment
Overconfidence Belief bias: only pay attention to things we
believe on Belief perseverance (confirmation bias): only
focus on what confirms our beliefs Framing
Limitations of heuristic judgments
Confirmation bias Fixation -mental sets/ rigidity: we fall victim into using the same problem solving because it has worked in the past -functional fixedness: we cant use an object differently that what it is made for
Obstacles to problem solving
Positive correlation between both Creativity: ability to create something new
and useful Types : -convergent thinking -divergent thinking
Creativity and cognition
Language Key component to humans thoughts
What component distinguishes language from other of communication?
-words (spoken, written or signed)
language
Phonemes : -phono-sound-smallest unit of sound in language-40 English language Morphemes :-smallest units of meaning-prefixes, suffixes Grammar semantics and syntax)
Language structure
Grammar: system of rules that govern language
-semantics: the study of meaning for morphemes words sentences -adding -ed suffix=past tense-Syntax: rules for combining words into sentences -adjectives comes before nouns
4 m-babbles speech sounds 10- babbles household language 12-one-word stage 24-two-word stage (telegraphic speech) 24+- rapid development into complete
sentences
Language development
Skinner vs. Chomsky Skinner-language= operant conditioning (nurture) -association: pairing objects with words -imitation: words and syntax modeled by others -reinforcement: praise Chomsky-language occurs naturally (nature)-Language acquisition device: brain is prewired for universal grammars-thus ready to learn any languages (switches will be set to specific language) -surface structure: organization of language -deep structure: meaning
Theories of language development
Babies- a built in readiness to learn grammatical rules Critical period-childhood: best/only time to master certain elements of language2nd language: those who learn it best(Chomsky: LAD-grammar switches set early)-Learning window-closes gradually after the age of 7-Hearing children/deaf children :parallel results-No language as child/ language learning capacity never fully develops
Lang development
More advanced in school Better at following complex directions Demonstrate better mental flexibility Tend to perform better on tests of creativity
Bilingual advantage
Motivation and emotion
Motives-needs, wants, desires leading to goal directed behavior
Drive theories-seeking homeostasis( internal balance)
Incentive theories-regulating by external stimuli
Evolutionary theories-maximizing reproductive success
Motivational theories and concepts
Instinct theory (fixed action patterns) : the theory that all behaviors will be determined by innate factors and biologically based behaviors that generally lead to survival
-the term instinct was becoming overused, so the psychologist changed the phrase they use to fixed…..
Theories of motivation
Drive theory: the idea that a physiological need created a state of tension ( a drive) motivating an organism to satisfy their needs
-states that a person will eat food as a result of a drive of hunger-aims for homeostasis or biological balance
Drive reduction theory
Cognitive social learning theory: our behavior is determined by 2 factors:
1) the expectations of meeting a goal2) the personal value of the goal -locus of control: our belief that we control the outcome of our own lives-instinisic vs. extinistic control Psychodynamic theory: our motivation comes from the
deep, dark parts of our unconscious minds (the id)-we have 2 basic needs1) Eros- desire for sex2) Thantos- aggression and destruction
Theories of motivation
Maslow argued that humans behave to satisfy specific types of need. He broke them into 5 categories:
1) biological: hunger, thirst, warmth2) Safety: avoid danger3) Attachment: wanting to belong to something 4) Esteem: seeing oneself as competent and
effective5) Self-actualization: being all that you can possibly
be (achieving your goals)
Maslow’s hierarchy / humanistic
Maslow said that there is a natural hierarchy or rank to the need human haves
Before one of the higher needs can be full filed the need on the levels below must be met, at least some degree
-most needs are met at a rate of about 85% before a person can move onto a higher need
Maslow’s hierarchy
Marlow pyramid pic
Brain regulation-lateral and ventromedial hypothalamus-periventricular nucleus Glucose and digestive regulation-glucostatic theory Hormonal regulation-insulin and lepton
The motivation of hunger and eating: biological factors
Learned preference and habits-exposure-when, as well as what Food-related cues-appearance, odor, effort required Stress-link between heightened arousal/ negative emotion and overeating
The motivation of hunger and eating environmental factors
Extrinsic motivation: a desire to perform a behavior because of promised reward or threats of punishments
Intrinsic motivation: a desire to perform a behavior for its own sake and to be effective (read a book because you want to)
Achievement motive=need to excel-work harder-Delay gratification-pursue competitive careers-situational influences on achievement motives-thematic apperception test (TAT)
Types of Motivation of achievement
James-Lange-feel afraid because pulse is raising Cannon-bard-thalamus sends signals simultaneously to the cortex and the autonomic nervous system Schacter’s Two-factor theory-look to external cues to decide what to feel Evolutionary theories-innate reactions with little cognitive interpretation
Theories of emotion
Cognitive appraisal theory: the thought that we look back on a situation and consciously decide how we should feel about the situation
-ex: grades, papers Opponent process theory: theory that we trigger
one emotion by suppressing its opposite emotion-ex: drugs- the highs experienced by some drugs are replaced with los (withdrawals). Eventually ppl take drugs no for the highs, but to avoid the lows
Psychological theories of emotion
Yerkes-dodson law A theory that a degree of psychological arousal helps performance, but only to a certain point. Too much or too little arousal can decrease performance. Also known as the inverted U
Yerkes-Dodson Law
Physiological response-fight-or-flight response (decide to fight or flee stress) -Seley’s general adaptation syndrome 1) alarm 2) resistance 3) exhaustion Brain-body pathways in stress--sympathetic adrenal medullary (SAM)-hypothalamic pituitary adrenocortical (HPA) PICTURE Figure 13.6
Responding to stress physiologically
Approach-approach: 2 positive things from which to decide
Approach-avoidance: decide between a positive or a negative
Avoidance-avoidance: 2 negative things from which to decide from
Types of conflict that cause stress
Behavioral response: coping-emotion focused
-frustration-aggression hypothesis-catharsis: relieve Defensive Coping-ego defense mechanisms-
Freud Constructive Coping-problem focused
Responding to stress behaviorally
Impaired task performance Burnout: antecedent-components-
consequences Posttraumatic Stress Disorders (PTSD)-
effects on hippocampus (cortisol)-prevalence of traumatic events
Reaction to traumatic stress Psychological problems and disorders
Effects of stress
Developmental psychology
3 phases -germinal stage= first 2 weeks conception, implantation, formation of placenta-embryonic stage= 2 weeks-2 moths formation of vital organs and systems-fetal stage= 2 months –birth bodily growth continues, movement capability begins, brain cells multiply
Prenatal stages
Separation anxietyAinsworth-the strange situation and patterns of attachment 1) anxious-ambivalent2) Avoidant3) secure: Developing secure attachment:-bonding at birth (contact comfort)-daycare-cultural factors Evolutionary perspectives on attachment
Early emotional development : attachment
Authoritarian: strict parent Permissive: I’m too busy, do whatever you
want Authoritative: firm but understanding, sets
boundaries but allows child input
Parenting styles
Stages theories: 3 components -progress through stages in order-progress through stages related to age-major discontinuities development Erik Erikson-eight stages spanning the lifespan (figure 11.8)-Psychosocial crises: determining balance between opposing polarities in personality
Stage theories of development :personality
Jean Piaget-Assimilation/ accommodation-4 stages and major milestones1) sensorimotor: object permanence 2) Preoperational: centration, egocentrism3) Concrete operational: decentration,
reversibility, conservation4) Formal operation : abstraction, abstract
thoughts
Stage theories: cognitive development
Kohlberg-reasoning as opposed to behavior -moral dilemmas
-measured nature and progression of moral reasoning-3 levels of each 2 sublevels1) Preconventional-punishment/ native reward2) Conventional – good boy/ authority3) Postconventional social contact/ individual principles and
conscience -Longitudinal studies (research issues (use of males) reasoning vs behavior
Development of moral reasoning
Critique Kohlberg’s work Kohlberg used most men Argued that males and females view morality in terms of
broad principles like justice and fairness Women are taught to view morality in terms of
responsibility towards an individual and a willingness to help others
For women, compassion is a stronger factor when making a moral decision
Helps explain why men and women regard morality of a particular situation in contradictory ways
Carol Gilligan
Pubescence-growth spurts-10-12 in fem 12-14 males Puberty-secondary sex characteristic-primary sex characteristics -menarche (menstruation) -sperm productionMaturation: early vs. late-sex differences in effects of early maturation
Adolescence
Life spam: max age possible for member of a given species
Life expectancy: the number of years that an evg members of a species is expected to live
Menopause: the end of menstruation and fertility
Adulthood and old age
Alzheimer’s disease-a progressive disorder that strikes older ppl, causing memory loss and other symptoms Fluid intelligence: includes inductive reasoning
and spatial ability, ability to reason speedily and abstractly, declines steadily throughout middle and late adulthood
Crystalized intelligence: includes verbal ability and numeric ability, one’s accumulated knowledge, skills and ability
Aging and intellectual functions
Elizabeth kubler-ross 5 stages in approaching death:
1) Denial: shock2) Anger: release of bottled up emotions3) Bargaining: seeking in vain for a way out4) Depression: final realization …5) Acceptance
