4/24-4/26: Psychological Disorders
Tuesday, April 17, 2012
4/17 and 4/24: Social Psychology- Attitudes+the Self, Relationships
Attitude
- Attitude: categorize stimulus along an evaluative dimension based on 3 components:
- Affective: emotions and affection (positive or negative)
- Behavioral: how you act toward object
- Cognitive: thoughts you have about the object (facts, knowledge, beliefs)
- Attitudes affect behavior?
- Attitudes = Poor predictors of actions
- Changing attitudes typical fail changing behavior
- LaPiere (1934)
- 92% said wouldn't accept Chinese guests
- All but 1 accepted them
- What Attitudes Affect behavior?
- Strong attitudes
- Important attitudes
- Easily Accessed attitudes
- Formed via Direct Experience attitudes
- Certain to you attitudes
- Attitude Theories
- Cognitive Dissonance Theory (Festinger 1957)
- Dissonance: psychological tension results behavior inconsistent w/ attitudes
- reduce dissonance and regain consistency
- Dissonance Reduction methods
- Change behavior
- quit smoking
- Trivialize dissonance
- Change attitudes
- weakness in studies linking smoking to cancer
- Add cognitions
- help me relax
- Example of Reducing Dissonance - Smoking
- Change Cognition A: I smoke-----> I don't smoke
- Change Cognition B: I smoke cigarettes + Research has Flaws instead of truth
- Add Cognition C: I smoke + Diseases+ They help me= relax
- Do all Inconsistent behaviors cause Dissonance?
- Cooper and Fazio, 1984
- No. Experience dissonance, behavior must be:
- Freely chosen
- Negative foreseeable consequences
- Responsible for choice felt
- Label arousal as negative
- believe arousal caused by something else, no dissonance
- Subtypes of Dissonance
- Insufficient Justification
- Fraternity initiation- think fraternity awesome to justify hazing
- Festinger and Carlsmith, 1959 - peg turning task
- Aronson and Mills, 1959(initiation into group)
- Post-decision dissonance
- Brehm, 1965: Difficult choice between 2 equally desirable items
- e.g. Droid vs Iphone
- Ignore Pros of other
- Spreading of alternatives
- Maximize difference in your decision's favor
- "I always knew she was the one"
- Compliance Techniques (4) (Cialdini)
- Foot-in-the-door technique: inducing a person to agree small request 1st
- Example: Wear Campaign Button; later, Ask for Billboard on their Lawn
- Why work
- Cognitive dissonance theory: desire to appear consistent in choices
- Door-in-the-face technique: Large request, then Smaller request
- Why work
- want to appear reasonable and good and maintain self-esteem
- Reducing request = Favor; Complying = Reciprocation
- Low-ball technique: ask someone agree to something basis of incomplete info
- becoming attached positively to object
- bid more/pay more than if knew all info
- That's-not-all technique: product high price, improve deal via adding product or lowering price
- salseman = reasonable, doing favor; reciprocate favor by buying
- Synyder's Self-Monitoring Scale (Self-esteem = SE)
- degree regulate behavior match situation
- High Self-monitor
- Social Chameleons
- Public self used
- Third Person talk
- Public self-consciousness Higher
- Pros
- Do Well in Social Situations
- Cons
- Insincere; Fake
- Low Self-monitor
- Consistent across situations
- Private self used
- First person speech
- Private self-consciousness Higher
- Pros
- People Know you
- Cons
- potential Social Ramifications
- Self-esteem- positive and negative self-evaluations
- State of Mind vs. Trait
- State of Mind = Situation dependent
- Trait = Same regardless
- Functions
- Leary (1995): Sociometer hypothesis
- High vs Low Self-Esteem
- High SE
- Highly Positive self-views
- Successful coping stressful times and setbacks
- More Thorough and Precise Self-knowledge
- Low SE
- Pessimistic; prone to thinking failure
- Adverse reactions to negative feedback
- Unrealistic goals tendency
- Enhancing Self-estemm: BIRGing
- BIRGing ( = Basking In Reflected Glory
- Cialdini 1976
- Football games affect University T-shirts use
- Win = more
- Lose = less
- Larger Margin of victory = Larger # of shirts
- "We" won vs. "They" lost
- CORFing = Cutting Off Reflected Failure
- Association Hurts SE = Cut off ties
- Self-esteem Maintenance Model
- Tesser, 1988
- People behave in manner maintain self-esteem
- How does another's performance Affect us?
- Influence depends:
- Quality of performance
- Closeness of other
- Relevance of dimension
- Factors interact different ways to maintain self-esteem
- Close other X good performance X non relevant dimension = increased self evaluation by reflection (BIRGing)
- Close other X good performance X relevant dimension = decreased SE by comparison (downward comparison)
- What happens when SE suffers?
- Close other Outperforms Self on Relevant dimension:
- Sabotage Other's performance
- Alter Self's performance
- Alter Closeness with Other
- Change self-definition
- Evolutionary Theory
- "Marketplace theory"
- Women = Value Status
- Men = Value Attractiveness
- Gender difference in Personal ads
- High income man seek attractive woman
- Attractive woman seek well off man
- Attractive women more likely marry successful men
- Why?
- Function of ability to Propagate Genes (Buss 1988,1989,1990)
- Male reproductive success = frequent pairings
- Female's reproductive success = finding provider
- Female's Youth-----> fertility sign
- Male's Status-------> ability to provide
- Support
- Men more likely to prefer youth and appearance = most important
- Women more likely look for "ambition, hard-working"
- Gender differences in Jealousy
- Buss, Larsen, Westen, Semmelroth (1992)
- Gender differences in Mate Preferences----> gender differences in Jealousy
- Asked imagine past relationship; Asked which Worse- Emotional or Sexual Betrayal
- Differences
- Men = 60% Sexual behavior worse
- Women = 80% Emotional worse
- Jealously- function of evolution
- Male = function of Reproductive Uncertainty
- don't know for certain baby = theirs
- Female = function of Resource Uncertainty
- money and house = certain ?
- Cons
- Can't do Experiments
- Another explanation for Jealousy Differences
- Double-shot theory: one infidelity implies other has happened too
- woman = man's emotional infidelity implies sexual infidelity has occurred
- man = woman's sexual infidelity implies emotional infidelity has occurred
- theory has been experimentally tested
- Communal vs. Exchange relationships (all relationships)
- Communal vs. Exchange (Clark and Mills 1979)
- Exchange: Tit-for-tat
- Communal: Expectations of Mutual Responsiveness
- Communal = Close friendships and Meaningful relationships
- Exchange = Superficial relationships w/ strangers and acquaintances
- Exchange
- Immediate repayment
- helped by acquaintance, repay it
- Want Own Contribution to be Distinguished
- Care about other's needs = Expecting Payback
- Helping each other = no change in mood
- Communal
- Immediate repayment may cause decreased in liking
- immediate repay = no trust of having back in future
- No clear distinction b/w our work and others
- " you did it. no, we did it"
- Care about other's needs even w/out payback
- trust they care/ will get your back sometime later
- Helping other = feel good
- Beginning of most friendships
- Michelangelo Phenomenon (romantic relationships)
- Self does not emerge independently; shaped by interpersonal experience
- Sculpting: mold each other's dispositions values and behavioral tendencies over time to reveal ideal self
- "Chip away" some aspects = reveal partner's ideal self
- Affirmation: partner elicits values and behaviors that are congruent with the self's ideal
- Partner Perceptual affirmation: degree to partner's perceptions of the self is congruent with ideal self
- See partner's true self
- Partner Behavioral affirmation: degree to partner's behaviors toward self is congruent with ideal self
- Bring out partner's true self
- Problems with Sculpting
- Sculpting = continuum ranging form
- Affirmation----> Failure to affirm-----> Disaffirmation
- Failure to Affirm: Partner elicits dispositions, values and behaviors that may be irrelevant to self’s ideal
- Disaffirmation: Partner elicits dispositions, values and behaviors that may be antithetical to self’s ideal
- Michelangelo Phenomenon
- At Best: Perceptual Affirmation----> Behavioral Affirmation-----> Self movement toward Ideal-----> Couple Well-being
- partner----------------->ideal self
- At Worst: Perceptual Disaffirmation-----> Behavioral Disaffirmation-----> Movement Away from Ideal-----> Deterioration of Couple Well-being
- ideal self... partner-------------------->
- Myths about Conflict
- Conflict can Always be Avoided
- Conflict = result from Misunderstandings and Unnecessary
- Conflict = Sign of Poor relationship
- How we deal with it
- Bad fights: Goal = Win
- Good fights: Goal = Compromise
- 4 types of Fighting Couples - John Gottman
- Volatile: conflict part of a larger passionate and loving relationship
- big fight, bigger make-up
- 5-1 ratio
- Validaters: Fair, Equal fights
- self-control and calm; validate other perspective
- 5-1 ratio
- Avoiders: Fight, Go away, Everything's fine
- "agree to disagree"
- 5-1 ratio
- Hostile: Frequent volatile fights
- 1-1 ratio
- 4 horsemen of the apocalypse:
- Contempt
- "eye-rolling"
- Criticism
- Defensiveness
- Withdrawing
- 5-1 ratio = Good
- Demand-Withdraw cycle
- One partner demands change, other partner withdraws
- Women = 2x likely make demand ; Why?
- Conflict-structure hypothesis: Women Most Want Change; Changer likely occupy Demand Role
- Women = less power ; want change more
- Cycle
- W demands, M withdraws
- W demands because M withdrew
- M withdraws because W's demands escalate
- W becomes frustrated at M's withdrawal

- Normative influence
- Informational social influence
- others = source of info
- desire to be right
- believe others can interpret ambiguous situation
- others can help us choose apt course of action
- Sherif, 1936

- Most Salient norm = Influence behavior
- How react to unambiguous stimuli?
- Asch study = one seen @ class with confederates saying wrong answer on line comparisons
- 76% conformed with wrong answer at least wrong
- Didn't want to look foolish; knew right answer though
- How do we know this isn't informational social conformity?
- Private responding = didn't conform
- Why do we Conform?
- Informational influence: others' behavior ---> info
- More Ambiguity-----> More Likely Conform
- Leads to Private Acceptance
- Normative influence: Social Approval
- Asch studies
- Leads to Public Compliance
- Normative Social Influence in our Lives

- confederate = participant in disguise
- expresses concern about heart condition
- confederate gets answers wrong------>participant shocks confederate
- Shock Recipient (recorded response)
- interjects----> owww----> begs to leave due to heart----->absolute silence
- Absolute silence: no response = wrong response -----> Shock
- Obeyed up to Very Strong Shock
- Over 60% shocked person at Death level
- Results of Obedience Levels:
- Research Command = 65%
- Fellow Subject Command = 20%
- Victim Command = 0%
- Two Researchers w/ Contrary Commands = 0%
- Message: Authority's Order = Crucial
- Why do we Obey Authority Figures?
- Motivation Choose Correctly
- Authorities = Experts
- Short-cut ---> Choosing Correctly

Exam 2 Review Session
- Intermittent Reinforcement Schedules
- Fixed: stays the same
- Fixed Interval- set time period
- Fixed Ratio - set quantity
- Variable: varies each time
- Variable Interval- unpredictable time period each time
- 10 minutes then 4 seconds
- Variable Ratio- unpredictable amount of number each time
- 4 then 7 then 3
- most resistant to extinction
- Top-Down processing vs Bottom-Up processing ( Happens Simultaneously)
- Bottom-Up = Sensory info----Memory
- Processing raw sensory info
- Sensation
- Top-Down = Perceiving info----- assign Meaning
- Thinking, Memory, Attention
- Perception
- Recency vs Primary Effect - Serial Position effect
- Primary - 1st things remembered; Longest Time to process info
- Recency- Last things remembered; Most Fresh
- Retrograde Amnesia vs Antregrade Amnesia
- Antregrade- new memories cannot be formed
- damage to Hippocampus
- left - verbal memories
- right - visual memories
- also can be cause by damage to prefrontal cortex

- Confabulations
- Retrograde - old memories can't be retrieved
- Interference
- Proactive - old info affects learning of new info
- locker combination
- Retroactive - new info takes place of old info
- forget old telephone number
- Heuristics
- Availability - readily available then it must happen often
- Difference Threshold (JND) vs Absolute Threshold
- JND
- minimum difference we can detect half of the time
- e.g. someone changing volume of music
- Weber's Law
- JND measured in proportion % rather than an amount
- 1 ounce to 10 ounce weight - noticed; 1 ounce to 100 ounce - unnoticed
- Absolute Threshold
- minimum amount of stimulus needed to detect something half of the time
- predicting something being there; e.g. hearing distant sounds
- varies with age
- Subliminal Messaging
- doesn't work in everyday life
- TV media violence
- can't say there's a causation
- can say there's a definite relationship with large-size effect
- makes violence more accessible in mind

3/29: Intelligence
- * Do NOT have to study Stereotype Threat
- Intelligence- mental quality consisting of ability to learn from experience, solve problems, and use knowledge to adapt to new situations
- Measurement of Intelligence
- General Ability or Several Specific Abilities?
- Disagreement on Correlates
- Considered a Concept
- Intelligence = General Ability?
- Charles Spearman: ONE general intelligence (g) underlies specific mental abilities
- score high on one factor, score high on others
- Thurstone
- pioneer of Multiple Factor Analyses
- Several Factors found by statistical analyses on exams of various intellectual abilites
- given labels such as verbal comprehension, numerical ability, spatial reasoning, and memory
- Gardner: we have independent multiple intelligences
- Gardner's 8 Intelligences
- verbal, spatial, understanding self, nature, math, movement, understanding others, music
- Savant Syndrome: limited mental capacities but an island of exceptional talent
- Hierarchical compromise between Spearman and Thurstone
- model in which specific abilities existed and were important but were all somewhat related to another and a global general intelligence
- Robert Sternberg: Three Aspects of intelligence
- Analytical: intelligence tests
- Practical: required for everyday tasks
- Creative: adapting to new situations, generating new ideas
- Intelligence vs Creativity
- Creativity: ability to produce novel and valuable ideas
- Intelligence
=Creativity - score 120 necessary but not sufficient for creativity
- very creative, don't tend extreme intelligence
- Convergent vs Divergent thinking
- Convergent = one right answer ; intelligence
- Divergent = multiple answers ; creativity
- sometimes subject to expectations and pressures
- Sternberg's 5 Components of Creativity
- Expertise - some knowledge of what you're being creative with
- Imaginative Thinking Skills - ability to see things in new ways
- Venturesome Personality - tolerate ambiguity, overcome obstacles, talk to many people
- Intrinsic Motivation- not reliant on external rewards
- Creative Environment - mentor, access to internet, etc.
- Emotional Intelligence: managing and understanding emotion
- 4 Components
- Perceive emotions - recognize
- Understand emotions - comprehend the type of emotion
- Manage emotions - help others/self
- Use emotions
- positively correlated with increased job performance
- How Measure Intelligence?
- Small correlation of +.15 head size and intelligence score
- Larger correlation of +.33 brain volume and intelligence score
- more intelligent, more brain synapses
- take in info more quickly and faster brain wave responses to stimuli
- look how individuals think and solve problems
- Trial and error
- Algorithm: step by step procedures
- Insight: solution comes to mind suddenly
- Heuristics: mental shortcuts, rules of thumb
- Heuristics: mental shortcuts to make quick and efficient judgments
- help select apt schema to use for processing
- 4 main types
- Availability heuristic
- Representativeness heuristic
- Anchoring and Adjustment heuristic
- Simulation heuristic
- Availability heuristic: base judgement on ease with which they can bring something to mind
- Representativeness heuristic: classify something on how similar is to a typical case (schema)
- e.g. quiet and organized representss librarian more than manager
- not a problem unless ignore base rate information
- Anchoring and Adjustment heuristic: uses number or value as starting point and adjusts one's answer away from anchor
- don't often adjust away from anchor enough
- most common anchor = self
- Simulation heuristic: ease of imagining something happening, influences reactions to it
- e.g. bronze medalists happier than silver medalists
- Intelligence test: assessing mental aptitudes and comparing to others
- Francis Galton: 1st psychologist to develop mental tests
- measures now outdated
- all intelligent people together, breed more intelligent race
- IQ test
- first made by Alfred Binet
- assumed all children follow same intellectual development
- Mental age: age at which child was performing at, relative to chronological age
- goal: ID children that needed help
- Lewis Terman
- Binet's norms didn't fit Californian children
- Adapted Binet's IQ test
- Stanford-Binet (SB) Intelligence Quotient
- IQ= mental age/chronological age x 100
- worked for children but not adults
- Current IQ test
- represents test-taker's ability relative to average performance of other own age
- average = 100
- WAIS: most commenly used intelligence test
- yields single full-scale intelligence score, 4 index scores and 12 specific subset scores
- Hierarchical model of intelligence with "g" and specific areas of ability "s"
- Like SB IQ, raw scores compared with age-based experiences
- average = 100 standard deviation = 15
- 2 Types of Mental Ability tests
- Aptitude tests: predict ability to learn new skill (SAT)
- Achievement tests: reflect what you already know (exams)
- Analogies: measure both aptitude and achievement
- Principals of Test Construction
- 3 Criteria
- Standardized
- Reliable
- Valid
- Standardized: person's performance meaningfully compared to others
- Reliable: dependably consistent scores
- two halves of test
- re-testing
- SB, and WAIS have +.9 reliability
- Valid: measures what it's supposed to
- Predictive validity: predict later performance
- Nature vs Nurture in Intelligence
- Genetic component
- Identical twins reared together = virtually same score
- Identical twins reared apart scores suggests 70% of intelligence is genetic
- ranges 50-75%
- Genes importnat to intelligence and learning disabilities
- Polygenetic: many genes involved, each less than 1% of variance in intelligence
- Environmental component
- adoption enhances intelligence scores of mistreated and neglected children
- fraternal twins tend score alike based on how treated
- Plomin and DeFries
- Adopted and children's scores correlate highly with birth parents

3/27: Application of Memory
- Eyewitness Testimony
- Eyewitness are often wrong!!
- Why are Eyewitnesses Wrong? - 3 Stages of Eyewitness Error
- Acquisition: Info Perceived
- Storage: Info Stored in Memory
- Retrieval: Info Retrieved Later Time
- Acquisition, Stage 1
- Influential Factors
- Time viewing event, night, Lighting conditions
- Brief Exposure, Poor Lighting, etc.
- Narrowed Focus
- Arousal and Emotions
- Weapons-focus effect
- weapon present, difficult to pay attention to culprit or anything else
- Own-Race Bias: people are better at recognizing faces of their own race than others
- Familiarity with own race but not other races
- "They all look alike"
- mock witnesses likely to accuse people of other races
- Platz and Hosch, 1988
- Clerks recognized more customers that were of their own race
- Storage, Stage 2
- Misinformation effect: tendency for False Positive info to become part of people's memory of an event
- Loftus and Palmer, 1974
- video clip of car crash, original info of car crash
=memory - three misleading questions, smashed/hit/contacted caused them to retrieve info not accurate
- Loftus, Miller and Burns, 1978
- car stopped at stop sign; car stopped at yield sign
- change info about event, change occurs in memory of event
- Loftus, 2004
- "lost in mall procedure: paricipants given 3 real memories and 1 false memory of being lost in mall
- asked to elaborate on stories 24-48 hrs later, 25% recalled vivid details of being lost in mall
- Malleability of Memory: changing beliefs or memories can influence what people think or do later
- Misinformation effect has been applied by Loftus to many situations
- May be Function of Source Monitoring
- Difficulty of remembering what the source was for each piece of info- e.g. saw stop sign, questioned about yield sign
- Info not Tagged correctly
- Recovered Memories: memories, typically of sexual abuse, "recovered" often via therapist help
- most academics argue against this
- False memory syndrome: people can recall a past traumatic event that is objectively false but they believe is true
- Vivid memories acquired especially if Suggested by another person like therapist
- Typically lack other objective findings to support claims
- Retrieval, Stage 3
- Foils
- 4-8
- Should Look like Actual suspect
- Goal: Reduce actual suspect's Distinctiveness
- Instructions
- Biased- pressure to pick someone, even if unsure
- " Pick the assailant" or "Concentrate and make a choice"
- more likely to make a false ID
- Fair- "suspect may or may not be here"
- Format
- Sequential lineups or "showups" are better
- Compare each face individually to memory of perpetrator
- Absolute Judgment
- Simultaneous lineups
- like multiple choice - which one best
- Relative Judgment
- Avoid Familiarity Bias
- Familiarity-induced bias: forget where we saw a face we recall
- don't include actual suspects in initial lineup
- People do not always remember where they saw a face
- Detecting Deception
- Use skills at decoding non-verbal behavior...
- average person- slightly better than chance at detecting deception
- Training and Practice can Improve one's skills
- Zukerman (1981)
- 4 Channels for Evaluating Deception
- words, face, body, voice
- Words and face = controllable
- Body = more revealing
- fidgety movements, restless shifts in posture
- Voice = best clue
- pitch rises, and more hesitations
Thursday, March 22, 2012
3/22: Memory
- Memory: persistence of learning over time through the storage and retrieval of information
- Personally Constructed
- events with more Personal Meaning = more easily remembered
- Function of Synaptic Changes
- Experience strengthens and makes more efficient neural connections= Long term potentiation
- more sensitized receptors, sending neuron needs less prompting to release nt
- Flashbulb memory: clear memory of emotionally significant moment or event
- may be function of emotion-triggered hormonal changes
- may be accurate directly after event
- not as accurate years later
- Stimulus----Sensory Memory--Attention---Short Term Memory---Encoding----Long-term Memory
- Sensory memory: immediate, inital record of sensory info
- Short-term memory: holds few items briefly
- Long-term memory: relatively permanent and limitless storehouse
- retrieval- process from long-term to short-term memory to access memory
- Encoding
- Automatic Processing: unconscious encoding of incidental info like space, time, frequency
- little-no effort
- Effortful Processing: encoding that requires attention and conscious effort
- Rehearsal helps
- Recency vs Primacy effects
- Recency- just saw it, in sensory memory
- Primacy- had time to rehearse, in short-term memory
- Durable and Accessible memories often produced
- info audible during sleep, not remembered; 1 hour before sleep - optimal memory
- Retain info better = Distributed over Time
- Many different pathways to encode info
- Visual Encoding: encoding to picture images
- more powerful with concrete imagery than abstract
- Acoustic encoding: encoding of sound
- Semantic encoding: encoding of meaning
- Craik and Tulving study: learning is easier when something has meaning
- ?Best: Imagery + Semantic
- Self-reference effect
- link meaning of something to yourself makes learning easier
- Mnemonic devices help remembering
- Chunking: organizing items into familiar, manageable units
- Hierarchies: subdividing concepts broad---narrow e.g. outline
- Storage
- Short-term: about 7 (giver or take 2) or 4
- Long-Term: limitless
- Memory does not reside in one single spot
- probably occurs in synapses and their neurotransmitters and hippocampus
- Arousal can enhance
- tragic, vividly remembered
- Weaker emotions, weaker memories
- flashbulb memories
- Retrieval
- Recall: ability to retrieve info not in conscious awareness
- Retrieval cues: help call stored info
- come from associations during encoding
- Priming
- elderly study
- Context effects: context of encoding = context retrieves info, remember better
- Deja vu: current situation, similar cues to earlier experience
- Mood-congruent memory: mood of storage = mood of recall, remember better
- Forgetting
- Absent-mindedness: inattention to details produces encoding failures
- Transience: storage decay over time
- Blocking: inaccessibility of stored info
- Misattribution: confusing info source
- Suggestibility: lingering effects of misinfo
- Bias: belief-colored recollections
- misconstruing past info
- Causes of Forgetting
- failure to encode info
- storage decay
- Retrieval failure:
- lack of relevant cues
- tip of tounge phenomenon
- not enough cues to access all
- Proactive interference: learning earlier info can interfere learning later info
- Retroactive interference: new info takes place of old info
- hour before sleep is an exception
- Motivated Forgetting: remembering things differently than happened
- motivated cognition: memory portray self in positive light
- Repression: defense mechanism that banishes anxiety-arousing thoughts,feelings, memories
- Memory Improvement Tips
- Overlearn
- Actively rehearse and think about material
- make material personally meaningful
- use mnemonic devices
- recreate encoding situation and mood
- study before sleeping or no other interference
- test knowledge
- Amnesia
- results from many kind of brain damage, particualry hippocampus
- two main types
- Anterograde amnesia:new info cannot be stored in long-term memory
- Retrograde amnesia: can't recall events preceding accident
- also cause by damage to prefrontal cortex
- Korsakoff's sydnrom
- alcohol runs down vitamin
- Confabulations
- making things up to fill the gap in memory\
- Can show signs of implicit memory but not explicit memory
- implicit: how to do something (unconscious)
- other brain areas including cerebellum
- unable to declare
- skills
- explicit: memory of facts and experiences that one can know and declare (conscious)
- hippocampus

3/20: Observational learning -Media Violence
- 9 out of 10 teens watch TV daily
- Americans who live to be 75 will have spent 9 years watching TV
- The number of minorities on TV is disproportional
- Minorities are depicted as illegal immigrants, drugees, gangbangers, maids, garbage men
- U.S. TVs present 3 violent acts per hour during prime time, and 18 per hour during children’s Saturday morning programming
- US has highest murder rate among developed countries globally
- More than 15,000 murders every year
- More than 92,000 reported rapes
- More than 7 million reported violent acts overall
- Every 5 minutes a child is arrested for a violent crime
- More than 50% of 5th graders report being a victim of violence (70% of those have seen weapons used)
- Guns kill an American child every 3 hours
- 87% of crimes are nonviolent; on TV 13% of crimes are nonviolent
- Average of 7 characters are killed on TV each night
- If applied in reality, this murder rate would wipe out U.S. population in 50 days
- Men gave more shocks after viewing violent erotica
- Violent erotica and other aggression can lead to desensitization
- conditioned stimulus = sexualized violence
- Media Violence
- #1 pastime
- 60-70% programs contain violence
- 70-80% show no remorse or penalty
- post elementary school
- thousands murders seen
- Since 1970s, know Link: Violent Media and Aggression
- Two Kind of Effects
- Short Term- increase in: hostile behavior, feelings, and attitudes
- Long Term- repeated exposure leads to: chronic hostility, desensitization to real violence
- Lab Studies:
- participants exposed violence more likely
- shock confederates
- recognize aggressive words
- criticisms
- exposure is brief and controlled
- experimenter bias: aggression may be sanctioned or encouraged
- no external validity
- External Validity is NOT a problem positive correlation
- Conditions likely to evoke violence
- Realistic violence
- e.g. video game graphics look very real and credible
- Reward/punishment of aggressor
- points system = direct reward, positive ending
- Arousal of observer
- violence to character elicits reaction
- ID of observer with aggressor
- immersion as if you were the aggressor
- Moral justification for violence
- violence needed in order to ___
- Longitudinal study
- Eron and Huesman (1960 -1985 various years)
- aggressiveness in 3rd graders, then again 10 years later
- result: Preference for TV violence significant correlation with more10 year later aggressiveness
- BUT: aggressiveness in 3rd grade did not correlate with more preference for TV violence 10 years later
- follow up results:
- more frequent TV at age 8, more serious crimes at age 30
- significant relationship violent TV and agressive behavior 1-22 years (various countries same)
- Liebert and Baron, 1972
- 15 min exposure to nonviolent and violent tv
- violent media associated with increased levels of aggression
- Video Games
- 90% 2-17 years play
- Specific effects due nature of game
- Columbine attacks: "Doom"
- Graphically violent games
- Increase Aggressive thoughts and behavior
- Related to Aggressive Behavior and Delinquency
- Violence is Directly Rewarded
- Increases Likelihood of Aggression
- Association between Media Violence and Aggression is Second Only to Smoking and Lung Cancer
- Primes Aggression; Catharsis Does NOT Work!
- Media Industry Responses
- Mirror to society
- False TV far more violent
- Giving Public what they want
- Maybe, sociteal violence hazardous by product; popular shows can be nonviolent
- Violence Sells
- False. Decreases memory for commercial messages
Tuesday, March 6, 2012
3/6: Learning
- Learning: relatively permanent chamge in an organism's behavior due to experience
- habituation = simplest form of learning
- Associative Learning: learning that certain events occur together
- Conditioning: process of learning associations
- Behaviorism: psychology should be an objective science, no reference to mental processes
- Classical Conditioning: learning associations and to anticipate events
- Pavlov = discoverer
- dogs' salivation experiment
- UCS = food
- UCR = drool
- CS = preceding bell
- CR = drool at bell's sound
- US (unconditioned stimulus) - stimulus that triggers UCR
- UR (unconditioned response) - an unlearned response
- CS (conditioned stimulus) - previously neutral stimulus (bell) that evokes conditioned response
- CR (conditioned response) - learned response to conditioned stimulus
- Principles of Classical Conditioning
- Acquisition: initial stage in associating neutral stimulus with an US
- Generalization: the CR can occur to stimuli that are similar to the CS
- Discrimination: the CR will NOT occur for ALL stimuli that are similar to the CS
- Extinction: pairing of CS and US stops, CR becomes weaker until it ceases
- Watson and Behaviorism
- founded behaviorism in reaction to introspection
- applied Pavlov's classical conditioning to "Little Albert" experiment
- white rat (CS) paired with loud noise (US) to induce fear (UR). later Albert feared the rat (CR)
- "Little Peter" experiment
- Systematic desensitization: repeated pairings of CS without US to extinguish classically conditioned responses
- treatment for phobia
- systematically associate an object without fearing it
- car phobia: every time give ice cream(CS) to person
- Pavlov's Contributions
- most organisms can learn via classical conditioning
- process of learning can be studied objectively
- modern applications of conditioning
- phobia patients take small steps
- drug addicts stay away from places associated with prior highs
- Biology of Conditioning
- Natural selection favor traits that aid survival
- e.g, taste aversion to food with food poisoning
- Classical vs Operant Conditioning
- Classical Conditioning- forms associations between an already held response and new stimuli
- doesn't control outcomes
- Operant Conditioning: forms associtations between its behavior and its consequences
- Organism controls outcomes
- Operant Conditioning: forms associtations between its behavior and its consequences
- B.F. Skinner
- believed that environmental consequences control all behavior = deterministic
- no room for personality or intenral components
- Skinner chamber
- strengthened - reinforcer diminished - punisher
- based on Throndike's law of effect : rewarded behavior is likely to recur
- Positive Reinforcer : strengthens response through presentation of positive stimulus (reward)
- Negative Reinforcer: strengthens response through removal of an aversive stimulus
- Different reinforcer schedules
- Continuous vs. Intermittent reinforcement
- extinction of CR happened far more quickly in continuous type
- intermittent- random, never know when- hope
- e.g., gambler
- Punishment: negative event that follows undesired behavior that decreases likelihood of response
- 4 main drawbacks
- Behavior is suppressed but not forgotten
- Punishment teaches discrimination
- can use cuss words around friends but not parents
- Punishment can teach fear
- Physical punishment can increase aggressiveness by modeling aggression
- Examples in real life
- clinical purposes: biofeedback
- hook up to machine to learn what feelings induce high blood presurre
- employees reinforced with cash, time off, vacations
- training animals
- Intrinsic vs Extrinsic motivations
- Intrinsic motivation: because seen as enjoyable
- Extrinsic motivation: because of reward/pressure
- Overjustification effect: overestimate extrinsic rewards and underestimate intrinsic motivation
- extrinsic rewards decrease intrinsic motivations = loss of interest in once enjoyed activity
- Observational Learning: learning by observing and modeling behavior of others
- possible reason -presence of mirror neurons in frontal lobe next to motor cortex
- Influential Factors
- if model is the same sex and behaves in a gender-role congruent way
- positive relationship between model and subject
- consequences of model are positive
- model in position of power
Thursday, March 1, 2012
3/1/12: Perception
- Perception is not always a replication of reality
- mind plays tricks on us
- Selective attention: process a limited amount of info and block out all other info
- Cocktail party effect: ability to attend to only one voice among many
- Perceptual Organization: organize perception to transform sensory info into meaningful perceptions
- Visual Capture: tendency for vision to retain dominant influence over other senses
- Perceptual Illusions
- visual system predicts what we think will happen
- Context Effect
- Gestalt: tendency to integrate pieces of information into meaningful wholes
- perceive parts as one whole of a different type, ex: flag made out of bunch of mini pictures
- Figure and Ground: organization of the visual field into objects (figures) and backgrounds (ground)
- ex: two faces that make up a vase
- Proximity: grouping nearby figures together
- Similarity: group figures that are similar
- Continuity: perceive continuous patterns
- Connectedness: spots, lines, and areas are seen as one unit when connected
- Closure: fill in gaps to make sense of it
- Depth Perception: function of ability to see things in three dimensions which enable us to estimate distance from us
- acquired knowledge
- Binocular cues: dependent on both eyes
- Monocular Cues: depth cues that are available to each eye alone
- Relative Height: objects higher in vision seen as further away
- Relative Size: if two objects are same size, the one that's smaller is perceived to be farther away
- Interposition: if an object blocks our view of another, it's perceived to be closer
- Linear Perspective: parallel lines that appear to converge convey distance; more they converge, greater distance
- Light and Shadow: light= closer dimmer = farther away; shading = info about light source
- Shape consistency: understanding the object may have different shape based on angle of view
- Size consistency: objects have consistent size even when distance changes
- reciprocal relationship between size and distance
- e.g. car at a distance
- Brightness Contrast
- different context can trick us
- e.g: board example
- Color Consistency
- depends on more than wavelength info received by cones
- also on context
- perceive color as function of light reflected relative to surrounding objects
- Comparisons govern perceptions
- Perceptual Set: mental predisposition perceive one thing and not another
- experiences, assumptions, expectations = influences on perception
- Schemas
- Summary
- Perception influenced by:
- Biological
- sensrory analyis
- unlearned visual phenomena
- Psychological
- selective attention
- kearned schemas
- Gestalt principles
- context effects
- perceptual set
- Social-cultural
- expectations and assumptions
- Extrasensroy Perception
- Parapsychology: study of paranormal psychology
- Extrasensory Perception: perception can occur apart from sensory input
- Telepathy: read/transmit thoughts into people's minds
- Clairvoyance: perceiving remote events
- Precognition: see the future
Tuesday, February 28, 2012
2/28: Sensation
- Sensation: process by which our nervous system receives and represents stimuli from the environment
- sensory receptors absorb raw physical energy
- raw energy transformed into neural signals which are sent to the brain
- Perception: organizing and interpreting sensory information, enabling us to recognize meaningful objects and events
- meaning assigned to sensory information
- Attention---Memory----Thinking Action = Sensation ; Thinking Action---Memory--Attention= Perception
- simultaneous processes
- Bottom-up, Attention to Thinking Action, = Sensation
- Top-down, Thinking Action to Attention = Perception
- Sensation
- subjective and cannot be measured using objective instruments
- evaluated using psychoanalysis
- Absolute Threshold: minimum stimulation needed to detect a particular stimulus 50% of the time
- vary with age
- Signal Detection Theory: understand why people respond differently to same stimuli and why the same people reactions change in different circumstances
- detecting a stimulus is determined by the signal and the subject's criterion (bias)
- Just Noticeable Difference (JND)
- definition: minimum difference a person can detect between any two stimuli half the time
- Weber's Law: JND is a function of proportions
- Subliminal messages:
- definition: words and pictures not consciously perceived that are supposedly influence behavior and judgment and attitudes
- FCC banned use of subliminal messages
- no control group in movie theater study
- No evidence of subliminal messages used in everyday life have any influence on behavior
- Greenwald (1991): study on subliminal messages
- Results: neither of tapes had any effect on people's memory or self-esteem
- sensation
- Person thinks self-esteem tape but really listen to memory tape, increase in memory
- perception
- Sensation: Vision
- seeing light = pulses of electromagnetic waves hitting eyes
- Frequency of color
- wavelength = type of color
- short = high frequency bluish colors
- long = low frequency reddish colors
- amplitude = intensity
- great = bright colors
- small = dull colors
- Sensation: The Eye
- Cornea
- light enters through here
- protects eye
- bends light to provide focues
- Pupil
- small adjustable opening
- size regulated by the Iris- a colored muscle surrounding the pupil
- Lens
- fine-tunes focusing of light
- Retina
- light sensitive surface on which rays focus
- images projected upside down
- Acuity - sharpness of vision
- Nearsightedness: images of far objects is focused before the retina
- Farsightedness: image of near objects is focused behind retina
- Retina contains millions of photoreceptor cells that convert light energy into neural activity
- Rods: sensivitee to light
- Cones: sensitive to color
- Rods vs Cones
- Rods
- concentrated at the outer edge of the retina
- share bipolar cells with other rods = combined messages
- not good at precise information
- perceived black and white
- sensitive in dim light
- Cones
- clustered in the fovea
- direct connection to cortex via bipolar cell
- better at precise info
- perceive color
- ineffectual in dim light
- types
- red
- green
- blue
- combo of types = multiple colors
- colorblindness
- one of cones not working
- Parallel Processing
- brain cell teams process combined info about
- color, motion, form, depth
- Recognition-----Retinal Processing------Feature Detection
- Sound
- waves as vibrations
- pattern of rapid wavelike movements of air molecules
- movement jolts surrounding air molecules and these collide with others
- 750 mph
- much slower than light
- travels in waves
- wavelength = pitch/type of sound
- short = high frequency/ high pitched sounds
- long = low frequency/ low pitched sounds
- frequency = intensity
- great = loud
- small = soft
- Process
- Collected in Outer Ear
- Auditory canal ----Eardrum
- Eardrum Vibrates Bones in Middle Ear
- Vibrations cause Hair Cell movements send neural message---- Auditory Cortex
- Locating Sound
- detection small differences between right and left ear
- measures just noticeable difference
- Hearing Loss
- Conduction Hearing Loss: caused by damage to the mechanical system of the ear
- Sensorinerual hearing loss (nerve deafness) : cause by damage to hair cell receptors or auditory nerves
- most often caused by aging or prolonged exposure to noise
- digital hearing aids can help by amplifing vibrations
- Sensory Compensation: slight enhancement of other sensory abilities after losing one channel
- Synesthesia: joing the senses: sensory crossovers
- error in terms of brain's responsivity
- e.g. hears words, visual cortex activates
- naturally and artifically done
- Somatosensory perception is essential for maintaining the integrity of the body, for controlling movements, etc
- Phantom sensations demonstrate the hidden but continuous operation of the somatosensory system
- Phantom Limb Pain
- subjective sensory awareness of an amputated part
- pins-and-needles, burning, shooting pain, cramps
- somatosensory cortex still active in that area
- over 70 % experience intense pain; 80% suffer this
- treatment - 7% success, virtual expensive
- mirror to remaining limb and the perceived movement tricks brain
- cause?
- possibility: Cortical Reorganization of the Somatosensory Cortex
- Sweet, Salty, Bitter, Sour
- Taste for MSG has also been id'd
- Survival Functions
- sweet = energy source
- salty = sodium essential to physiological processes
- sour = potentially toxic acid
- bitter = potential poisons
- Obesity and evolved processes
- Fittest of ancient = preferred high calorie food, ate to capacity, efficient body-fat storage metabolsim, hunting and killing = high energy
- Current society
- food no longer requires tremendous energy expenditure
- cultural factors contribute to high calorie food central status
- Process
- Airborne molecules----- receptors at top of your nose
- sniffing swirls air to receptors
- The receptor cells------ brain’s olfactory bulb----- temporal lobe’s primary smell cortex and parts of the limbic system involved in memory and emotion
- Smell processed near memory area
- smell trigger memory
- Women have superior sense of smell
- theory: help select better mate
- Miniski and Wedekind (2001)
- ovulation (enhanced smell)
- Why'
- segment of DNA, MHC ( major histocompatibility complexe) codes for immune system functioning
- MHC is co-dominant
- tend to select different MHC person
- MHC manifests itself in proteins secreted
- Female rats select with dissimlar MHC mates
- women and cotton t shirt experiment
- MHC dissimilar = mate
- MHC similar = akin to family member
- overly intense disliked
- suggests because strong odors though to indicate disease

Study Guide Exam 1 (2/20)
Psychology- the scientific study of behavior and the mind
behavior: observable actions
mind: subjective experiences
behavior: observable actions
mind: subjective experiences
Chapter One: Methods
- Hypothesis- testable relationship between two constructs
- cannot be proved true; only can prove falsity
- support with data and more complexity makes it become a theory
- Theory- organized set of principles used to explain observed phenomena
- testing: predictions--research tests--either confirmed or not--more or less confidence
- Random Sample-each person in the population has an equal chance of inclusion
- phone book and college student selection would NOT be random sampling because the choices in the groups are too alike: college = 3% of majority, phone book= zip code
- Three Research Methods
- Observational
- Correlational
- Experimental
- Observational
- Focus: Description
- observes people and systematically records measurements of their behavior
- ex: archival analysis
- Pros
- nice place to start
- Cons
- Hard to
- Implement
- Quantify
- Bias
- Correlational
- Focus: Prediction
- observe the relationship between two or more variables
- Pros
- able to study issues that would be otherwise unethical or impossible
- Efficient:allows more collection of info and test more relationships
- Cons
- CANNOT conclude a casual relationship
- Correlation Coefficient-statistic that assesses the relationship between two variables:
- how strongly and what direction associated
- positive/negative
- Experimental
- Focus: Causality
- Requires:
- Manipulation of one or more variables
- Vary variables of interest across groups and keep everything else constant
- Independent Variable(IV): factor manipulated by researcher and the cause of change in
- Dependent Variable(DV): outcome being studied/evaluated, the response to IV
- Random Assignment
- each participant in the sample has an equal likelihood of being placed in any condition
- NOT the same as Random Sampling
- CRUCIAL: necessary to establish causality
- If people are assigned randomly to different groups , any difference has to be cause by IV
- Correlational vs Experimental Recap
- IV
- C = varies naturally
- E = manipulated by researcher
- Random Assignment
- C= NO
- E= YES
- Test Causality
- C= NO
- E= YES
- Validity in Research
- Two types associated with research
- Internal Validity- the effects in the DV are caused by the IV
- External Validity- degree to which research findings can be generalized to "real world" effects
- Experimental Settings
- Field Experiment- examines behavior in its natural habitat
- pro: high in
- Laboratory Experiment- done in artificial setting
- Solution:
- do both
- Bias in Research
- Experimenter Bias
- Subject Bias
- Experimenter Bias
- Subtle cues from researchers may influence participants' behavior
- e.g. Clever Hans and his 'counting' horse
- Solutions
- "Blind" Research Assistants
- Standardize research procedures
- Subject Bias
- Mere fact of knowing you're studied can alter your behavior
- Solutions
- Unobtrusive measures
- Do Not Tell participants goals or hypotheses
- Ethical Issues
- Mandated:
- Informed Consent
- Debriefing
- Weighing of benefits and costs of research

- Outline of Primary Parts
- The Nervous System
- Neurons
- The Brain
- Drugs and their Effects
- The Nervous System
- definition: electrochemical communication network that connects the brain and spinal cord to all organs, muscles, and glands
- Central Nervous System (CNS): brain and spinal cord
- Peripheral Nervous System(PNS): nerves that radiate from the spinal cord (CNS) to the rest of the body
- Somatic Nervous System: transmits signals from sensory organs to CNS and from CNS to skeletal muscles
- Automatic Nervous System: connects CNS to smooth involuntary muscles and organs and to glands
- Sympathetic division: prepares body to react and expend energy in time of stress
- fight/flight
- Parasympathetic division: conserves resources; maintain bodily functions
- rest and digestion
- CNS
- Spinal cord relays messages btwn brain and extremities
- receives signals from our senses, relays them to brain, and sends info back from brain to control behavior
- Signals: Senses---Brain---Control behavior
- reflexes
- behaviors controlled by solely by the spinal cord
- PNS
- bundles of axons that communicate between spinal cord and rest of body
- divided into subsystems:

Chapter Three: States of Consciousness
- Consciousness: awareness of ourselves and our environments
- Book information
- Dual Processing
- info is simultaneously processed on separate conscious and unconscious tracks
- Selective Attention: focusing of conscious awareness on a particular stimulus
- cocktail effect- one voice heard among many
- inattentional blindness- visual object unseen due to attention being elsewhere
- change blindness- failure to notice change in environment
- REM rebound
- tendency for REM sleep to increase following REM sleep deprivation ( created by repeated awakenings during REM sleep)
- Dissociation
- split in consciousness, which allows some thoughts and behaviors to occur simultaneously with others
- Psychoactive drug
- alters perceptions and moods
- Tolerance
- diminishing effect of drug, leads to larger doses
- Withdrawal
- discomfort and distress following discontinued use of addictive drug
- Physical dependence
- physiological need marked by unpleasant withdrawal symptoms
- Psychological dependence
- relieve negative emotions, psychological need
- Addiction
- compulsive craving and use spite of consequences
- Methaphetamine
- all effects of amphetamines in addition to reducing baseline dopamine levels
- Sleep
=Unconsciousness Because.. - Brain continues to process information both external and internally generated
- Brain remains active
- Easily awakened
- Theories for Necessity of Sleep
- Protection from dark
- evolutionary perspective: also from predators
- Restores Body Tissue and Allows Brain to Reorganize itself and Consolidate Memories
- Allows us to Grow
- Pituitary Gland releases hormone
- Sleep Research
- Genetic variability in need
- sleep at least 9 hrs without disturbances
- keeps track of sleep debt for at least two weeks
- 7-8 hrs sleep tend to outlive those who sleep less
- Sleep-Wake Cycle
- major period night
- smaller period afternoon
- Naps: focus attention and help make complicated decisions
- Circadian Rhythm : biological clock regulates body rhythms every 24 hours
- largely affected by sleep-inducing hormone, Melatonin
- produced in pineal gland
- only produced in darkness
- bright light inhibits melatonin and resents clock
- thought to contribute to depression
- Morningness-Eveningness
- Horne and Ostberg, 1976
- stable preferences for different times of day
- thought to be function of variance in circadian rhythms in body temps and endocrine secretion
- Morning people- peak body temp and alertness earlier in day
- Evening people- peak body temp and alertness later in day
- Sleep Stages
- sleep cycle: 90 minutes
- 5 stages and regress through them
- before falling asleep, when mind is relaxed and awake = alpha waves
- Stage 1
- 5 minutes
- Fantastic images, hallucination
- Sensation of falling, floating, jerking
- Stage 2
- 20 minutes
- can wake up without difficulty but clearly asleep
- Sleep-talking: can begin here but also occur in other stages
- spindles: bursts of rapid brain activity; happen here
- Stage 3
- 30 minutes
- Transitional
- Delta Waves begin to be slowly emitted
- Stage 4
- 30 minutes
- Slow-wave sleep
- Delta Waves
- Hard to awaken
- End of stage: sleepwalking/bedwetting
- Stage 5
- Regress through Stage 3----Stage 2: REM
- REM periods get longer as night progresses
- 10 minutes
- Brain waves nearly resemble that of Stage 1 EXCEPT
- heart rate rises, breathing increases, eye movement
- Beginning of a Dream
- about 20-25 % of sleep
- Brain's cortex active
- Brainstem blocks messages = relaxed
- Sleep Disorders
- stress during day = average of 1 hr less sleep each night
- Insomnia: persistent problems in falling/staying asleep
- 10-15% of adults retain it
- stimulants cause overload for half of it
- Narcolepsy: people spontaneously collapse into REM sleep
- 1 in 2000
- absence of neural center that produces neurotransmitter hypocretin
- New research: might be auto-immune disease
- Sleep Apnea: intermittently stop breathing during sleep
- 1 in 20 (mostly overweight men)
- causes CNS to stop functioning
- Parasomnias:
- sleep-walking, sleep-talking, tooth grinding
- Night terrors: sitting up, walking around, talking, heightened heart rate
- More common in kids, not unusual in adults
- Generally happen in DEEP sleep = stages 3 and 4, NOT REM
- Sleep Deprivation
- peak age of occurrence: 20
- exhibit slower reaction times and increased errors
- Cumulative
- body needs to make up for lost time the next night
- Level Alteration
- Lowers Leptin
- signal of starvation
- Raises Ghrelin
- increased appetite
- body mass index proportional to sleep loss
- Dreams
- tend to be about what we did during the day
- The 5 Theories for why
- Psychoanalytic perspective
- Activation-synthesis theory
- Neurocognitive theory
- File away Memories
- Develop/Preserve Neural Pathways
- Psychoanalytic Perspective(Freud)
- Freud: dream as wish fulfillment
- Dream = royal road to understanding unconsciousness
- Manifest Content: what a person remembers and consciously considers
- Latent Content: underlying hidden meaning (symbols)
- Dreams are disguised fulfillment of repressed infantile wish
- Freud used free association and dream analysis to access unconscious conflicts
- most adult dreams can be traced back to erotic wishes
- Weakness: difficult to test scientifically
- Activation-Synthesis: brain experiences spontaneous activity as sensations
- Pons Input: activate image producing area of brain
- Amygdala has increased activity
- lack of activity in frontal lobe
- links sensations together in synthesized pattern
- some aspects of brain related to dream activity
- damage to limbic system = dream impairment
- meaning = by product, assigned by personality
- Weakness: difficult to test scientifically
- Neurocognitive Theory: dreams = "special" kind of thinking
- persistent cortex activity
- reduced sensory stimulation
- loss of voluntary control of thinking
- ability to recall dreams require cognitive maturity
- elements of what's on mind
- adult ones usually boring
- File Memories: Information processing in which sort the day's experiences and encode them in memory
- REM sleep
- storage of memory
- erasure of memory
- resolution of emotional experiences
- transfer of memory from hippocampus to long term storage
- Develop/Preserve Neural Pathways: Physiological function to
- stimulate brain and develop/preserve neurons
- dream to exercise synapses
- infants with developing neural systems have abundant sleep
- REM sleep has changes in breathing, blood flow to brain, brain activity
- Sleep Paralysis
- experience
- wake up paralyzed, detects presence, feels fear, perceives buzzing and strange lights
- dreaming while awake
- Hypnosis
- suggestion that certain perceptions, feelings, thoughts, or behaviors will occur
- depends on suggestibility
- those with rich imagination are susceptible
- trance state
- extreme suggestibility, relaxation, heightened imagination
- daydreaming comparison
- age regression cannot occur
- posthypnotic suggestion:
- carried out after hypnosis
- worked to alleviate headaches, stress, asthma
- can't work with drugs/addictions
- Other Priming Methods
- Memory task
- prime = words asked to memorize
- Scrambled sentence task
- prime = words' relating to prime
- Word search
- encoded in word search = prime
- Physical presence of Stimuli
- Subliminal Priming
- to quick to be aware of
- steps
- brief presentation
- mask with other stimulus
- happy followed by XXX

- Zygote (2 weeks)--Embryo(end of 2 weeks to 9)----Fetus(9 weeks to birth
- Teratogens
- chemicals and viruses that can harm embryo or fetus
- Habituation
- less responsiveness with repeated situations
- Autism

- Basic Trust(Erik Erikson)
- apt experiences with care givers develop sense of predictable and trustworthy world during infancy
- Menarhce - first menstrual period
- REST WILL BE LOOKED AND HIGHLIGHTED IN BOOK
- Developmental Psychology§The study of how people grow, mature, and change over the life span
- Key themes
- Nature vs. nurture: how do genetic factors versus situation factors influence our development
- Continuity vs. stages: does development occur gradually or w/in clear stages
- Stability vs. change: how consistent are we as people from one stage in life to another?
- Research strategies:
- Cross-sectional: people of different ages are examined at the same time and their responses are compared
- Longitudinal: same subjects are retested at different times in their lives
- Infants Research
- Habituation:
- An infant will indicate interest with its gaze
- An infant will become “habituated” to a visual stimulus = way to asses perception/memory
- Turns towards human voices
- An infant will suck on a pacifier more vigorously when it hears its mother’s voice
- Prefers objects 8-12 inches away
- Typical distance of mother to infant when nursing
- Recognizes mother’s smell
- A baby will turn towards the smell of its mother
- Prefers objects that look like human faces
- Preference for “beautiful” faces = symmetrical
- Prefers higher-pitched voices and “baby talk”
- parents in many cultures use exaggerated speech and high-pitched voices dubbed "parentese."
- The Infant: Neural Development
- Babies have most of the brain cells they will ever have
- But their nervous system is still developing = they have less neural connections
- Growth spurt from 3-6 in frontal lobes that enables rational planning
- Association areas last to develop
- Neural pathways for language/agility surge until puberty when pruning process occurs
- Children’s memories are processed differently after 4
- Cognitive Development: Jean Piaget (1896-1980)
- How do children incorporate new information with what they already know?
- They form schemas – mental representations of the world
- They assimilate new info into schemas and adjust schemas (accommodate) to fit new info
- Theory: children are curious, active, intelligent and constructive thinkers with a DIFFERENT TYPE of logic
- Cognitive development stages Piaget
- Sensorimotor stage (birth-2 yrs)
- Experience the world through sensory and motor interactions
- E.g. looking, hearing, touching, mouthing, grasping
- 2 Key aspects:
- 1) Lack of object permanence: awareness that objects continue to exist when not perceived
- Acquire object permanence ~ 8 months
- 2) Separation anxiety: acquisition of object permanence = misses mother
- Preoperational stage (2-6 years)
- Children too young to perform mental operations
- Words and images are used to symbolize objects
- 2 key aspects:
- 1) Conservation: No understanding of conservation – physical properties of an object stay the same
- 2) Egocentrism: unable to adopt another perspective, self-centered
- Concrete operational stage (7-12)
- Definied by acquisition of:
- Logical reasoning: grasp the idea of conservation
- Perspective taking: no longer egocentric
- Grouping
- Subgroups/ serialization
- Can add and subtract without counting
- Formal operational stage (12 yr +)
- Reasoning expands from concrete to
- Reasoning on a logical, hypothetical level
- Abstract thinking
- Systematic reasoning, but may occur earlier than Piaget had thought
- Self-concept develops
- Piaget’s legacy
- 1st to realize that children actively construct meaning
- Children aren’t developmentally ready for certain tasks until they are at the stage
- Cognitive milestones
- BUT: Development is more continuous than Piaget thought
- Evidence of each “stage” occurs earlier than Piaget though
- Children have high suggestibility
- Social Development: Attachment styles:
- Harlow:
- studied attachment in primates
- Separated infant rhesus monkeys form mothers after birth and provided them with two dummy ‘mother’ options
- Wire mother with feeding bottle
- Cloth mother
- *NB: monkeys preferred cloth mothers
- What happens when babies are deprived of social contact?
- When monkeys reared in total isolation were placed with other monkeys their age, they either cowered in fright or lashed out aggressively
- When they reached sexual maturity, many were incapable of mating
- If artificially impregnated, they were neglectful and sometimes murdered their offspring
- Strange situation test
- Ainsworth:
- Strange situation test to determine strength/nature of attachment bonds b/w mothers and infants (12-18 months)
- Results
- Final stage of test:
- the stranger leaves and the mother returns to comfort her infant.
- DV: the infant's reaction to reunion with mother
- the degree to which the infant seeks/avoids proximity to mother
- the degree to which infant tries to maintain/resist contact with his mother
- Three Attachment groups (based on results)
- Secure: upset at departure but comforted upon return
- Avoidant: no distress at departure, nor response upon return
- Anxious-Ambivalent: upset at departure, difficulty in being comforted upon return
- What causes attachment style?
- Several key aspects:
- 1) Responsiveness of parental behaviour
- 2) Consistency and sensitivity of care
- Expectations developed with primary caregiver thought to serve as a template for future relationships
- *NB: ‘insecure’ attachment only evident in times of stress or conflict!
- (Avoidant) : I am somewhat uncomfortable being close to another; I find it difficult to trust them completely, difficult to allow myself to depend on them. I am nervous when he/she gets too close, and often, the he/she wants me to be more intimate than I feel comfortable being
- (Anxious-ambivalent) : I find that the other person is reluctant to get as close as I would like. I often worry that he/she doesn’t really love me or won’t want to stay with me. I want to get very close him/her, and this sometimes scares him/her away.
- (Secure) : I find it relatively easy to get close to another and am comfortable depending on him/her. I don’t often worry about being abandoned or about him/her getting too close to me.
- Attachment Style in Adults
- Hazan & Shaver, 1987
- Attachment style originates from relationship with primary caregiver = working models
- Model of self: expectation of whether the self is worthy of support and affection
- Model of other: expectation of the likelihood that other people are reliable and will treat the self well
- Translates to how individuals act in romantic relationships
- “Style” evident in times of stress
- Attachment styles
- Secure:
- Responsive caregiver
- trusting, view that one is worthy and well-liked
- Satisfying romantic relationships
- Anxious-Ambivalent:
- Erratic caregiver
- Fall in love easily, worries, fear of being abandoned, idealizes and devaluates partner,
- Relationship = emotional highs and lows, jealousy and conflict
- Avoidant
- Negligent caregiver
- Independent, difficulty with intimacy, preference for social distance
- low levels of intimacy, commitment and satisfaction, and high levels of negative emotional experiences
- Coping strategies
- Secure: talk to partner
- Anxious: rumination
- Avoidant: distancing
- Distribution in population
- 56% Secure, 25% Avoidant, 19% Anxious
- Gender differences
- Men more likely to be avoidant, women more likely to be anxious
- Avoidant & Anxious-Ambivalent pairings
- Secure buffer
- Continuous vs. categorical
- 4 category model
- Static vs. flexible
- Problems with attachment styles
- Several continued criticisms of attachment style research:
- 1) Attachment styles are just another personality variable
- 2) Attachment styles have no tested, organized universal format or standard
- Continuous? Categorical? 3? 4? Hierarchical? WHO KNOWS
- Everyone is just focused on a little piece of the puzzle
- Stages of Social Development
- Erik Erikson
- Development of "Ego Identity"
- changes constantly with regards to environment
- experience of self based on interactions
- Competence and personal adequacy
- each stage = different aspect of mastery
- stage managed well = feelings of competence
- stage managed poorly = feelings of inadequacy
- Erikson's 8 Stages of Life
- Stage 1: Infancy
- Trust vs Mistrust: How can I be secure?
- upbringing and learning
- Stage 2: Early Childhood
- Autonomy vs. Shame/Doubt: ....be independent?
- controlling parents---fail----shame/doubt
- Stage 3: Childhood (play age)
- Initiative vs Guilt: .....be powerful?
- excessive punishment = guilt
- no punishment = excessive initiative/power
- Stage 4: Childhood(school age)

- 3). Postconventional Morality: people are less concerned with maintaing society for its own sake and more concerned with principles and values for a good society
- Stage 5: Social Contract and Individual Rights
