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

Page 2: 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

Page 3: John B. Watson

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

Page 4: John B. Watson

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

Page 5: John B. Watson

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

Page 6: John B. Watson

Classical-stimuli Operant-consequences

Classical vs operant conditioning

Page 7: John B. Watson

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

Page 8: John B. Watson

Testing rewards and punishment Experiment on rats

The skinner box

Page 9: John B. Watson

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

Page 10: John B. Watson

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

Page 11: John B. Watson

Primary reinforces-natural reinforces (food, water) Secondary reinforces-things we’ve learned to value: (money)

Types of Reinforces

Page 12: John B. Watson

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

Page 13: John B. Watson

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

Page 14: John B. Watson

Reinforcement schedules=pattern of reinforcing behavior

Administered in 2 ways: Ratio-number of responses Interval-time

Reinforcement shedules

Page 15: John B. Watson

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

Page 16: John B. Watson

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

Page 17: John B. Watson

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

Page 18: John B. Watson

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

Page 19: John B. Watson

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

Page 20: John B. Watson

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

Page 21: John B. Watson

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

Page 22: John B. Watson

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

Page 23: John B. Watson

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

Page 24: John B. Watson

Insight learning (aha!) Sudden grasp of problem Wolfgang Kohler: Chimpanzees Sudden insight, not gradual strengthening od

S-R association

Cognitive Learning

Page 25: John B. Watson

Cognition

Page 26: John B. Watson

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

Page 27: John B. Watson

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

Page 28: John B. Watson

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

Page 29: John B. Watson

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)

Page 30: John B. Watson

Permanent and limitless storehouse of the memory system

Long term memory

Page 31: John B. Watson

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

Page 32: John B. Watson

2 ways:-automatic processing-effortful processing

Encoding

Page 33: John B. Watson

Automatic:-unconscious encoding-location, time and frequency-retracing steps to find your keys-also becomes automatic with practice

Encoding

Page 34: John B. Watson

Effortful processing-attention/ conscious effort-studying for a test-through practice effortful can become automatic

Encoding

Page 35: John B. Watson

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

Page 36: John B. Watson

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 …

Page 37: John B. Watson

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

Page 38: John B. Watson

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

Page 39: John B. Watson

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

Page 40: John B. Watson

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

Page 41: John B. Watson

Recognition; multiple choice Recall; long response

Retrieval recall vs recognition

Page 42: John B. Watson

Memory = web of associations Priming “strand or web of associations that

leads to a specific memory”

Retrieval cues

Page 43: John B. Watson

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

Page 44: John B. Watson

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

Page 45: John B. Watson

Encoding failure Storage decay Retrieval failure

3 ways we forget

Page 46: John B. Watson

Don’t encode what we don’t need Not encoding/ no LTM

Encoding

Page 47: John B. Watson

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

Page 48: John B. Watson

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

Page 49: John B. Watson

REPRESSION: Psychoanalytic theory-Freud’s theory of

repression -we push away uncomfortable memories -contradicts theory that emotions/stress hormones strengthen memories

Retrieval failure

Page 50: John B. Watson

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

Page 51: John B. Watson

About how fast were the vehicles going where they slammed into each other

OR When they ran into each other?

Misinformation effect

Page 52: John B. Watson

Forgetting source of a memory Where did they hear that? One of the frailest parts of our memory

Amnesia

Page 53: John B. Watson

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

Page 54: John B. Watson

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)

Page 55: John B. Watson

Cognitive problem solving-algorithms: always leads to right answer -heuristics: saves you time, shortcut-insight:

Problem solving with cognition

Page 56: John B. Watson

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

Page 57: John B. Watson

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

Page 58: John B. Watson

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

Page 59: John B. Watson

Positive correlation between both Creativity: ability to create something new

and useful Types : -convergent thinking -divergent thinking

Creativity and cognition

Page 60: John B. Watson

Language Key component to humans thoughts

Page 61: John B. Watson

What component distinguishes language from other of communication?

-words (spoken, written or signed)

language

Page 62: John B. Watson

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

Page 63: John B. Watson

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

Page 64: John B. Watson

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

Page 65: John B. Watson

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

Page 66: John B. Watson

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

Page 67: John B. Watson

More advanced in school Better at following complex directions Demonstrate better mental flexibility Tend to perform better on tests of creativity

Bilingual advantage

Page 68: John B. Watson

Motivation and emotion

Page 69: John B. Watson

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

Page 70: John B. Watson

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

Page 71: John B. Watson

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

Page 72: John B. Watson

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

Page 73: John B. Watson

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

Page 74: John B. Watson

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

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

Page 77: John B. Watson

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

Page 78: John B. Watson

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

Page 79: John B. Watson

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

Page 80: John B. Watson

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

Page 81: John B. Watson

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

Authoritarian: strict parent Permissive: I’m too busy, do whatever you

want Authoritative: firm but understanding, sets

boundaries but allows child input

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

Page 93: John B. Watson

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
