cognitive psychology
- the mind
- emerged from behaviorism
Cognition
mental process of thinking, learning, and understanding
(mind part of mind-body problem)
- cognitive processes mediate the relationship between behavior and environment
knowledge
is stored representations
thinking
is a manipulation of these representations
thinking slow
deliberative, logical, rational
- (we thought we all thought rationally, rational actors)
thinking fast
instinctive, emotional
heuristics
shortcuts used to reduce the amount of thinking that is needed to make decisions
- cant always narrrow down options
availability heuristic
decisions are influenced by how readily examples are recalled
- politics: the more you mention an issue, the more people think how important it is
- advertising: the more recognizable a product is, the more likely you are to buy it
- medicine(sympotoms r more likely to be associated with a common ailment than a rare one)
representative heuristic
making a judgement by comparing a person/object to a prototype
conjunction fallacy
likelihood of multiple events happening together is more likely than any of those events happening individually
simulation heuristic
people express more regret over outcomes that are easier to imagine or "stimulate"
(outcome is the same but you just missed it, plane example)
confirmation bias
a tendency to search for information that confirms your expectation (and ignore information that refutes it)
rosenhan study
conf. bias example
- group of ppl reported hearing voices to a mental health institution, no other symptoms
- all were admitted, acted normally after admission\
- all of their theraposts found instances from past that would explain voices
anchoring
setting a reference point (usually first piece of info) to simplify a situation
- put alot of weight on the first thing we see
sunk-cost fallacy
a person is reluctant to abandon a strategy if they are heavily invested in it ( loss aversion)
emotions and decision making
emotions, either felt or anticipated, can affect how ppl make decisions
affective forecasting
predicting how we will feel with any given outcome
- we are bad at this!
( parapalegic and lottery winner ---1 year later---> same level of happiness)
- we chase things that wont make us happy in the long run
first IQ test
Binet-Simon Scale (1905)
- used to classify ppl
- french wanted measure to figure out if kids were ready for school
mental age
how many questions you get right, intelligence for classification, idiot, low grade imbecile.... moron
intelligence and eugenics
- og behind binet test was positive but then....
- shift in US against intellectual disability
- used binet test to idenitfy intellectual disability
- tried to control disability thru eugenics, forced sterilization
army alpha/beta tests
assessed cognitive abilities of recruits, ability to serve, and appropriate roles (WWI)
- alpha tests for literate individuals
- beta tests for illiterate recruits
eventually published, used widely in business and education
- became the basis for famous wechsler(most widely used) intelligence tests (WISC, WAIS)
three theories of intelligence
one- overall (or general) intelligence: g, spearman
two- fluid and crystalized intelligence
multifactor: many
fluid intelligence (two factor theory)
natural abilites: reasoning problem solving, in unfamiliar situations
crystallized intelligence
knowledge- gained from experince used to solve problems
gardners 8 intelligences
word smart - linguistic
number smart - logical - mathematical
picture smart - visual-spatial
body smart - bodily-kinesthetic
music smart - musical
people smart - interpersonal
self smart - intrapersonal
nature smart - naturalist
more advertisement than research
intelligence test structure
will produce intelligence quotient (IQ) which is a standard score ( we determine standard avg = 100)
- most intelligeence tests include subtests that can be grouped into subscales
- broad subscale ex: verbal vs. nonverbal
- specific subscales: verbal comprehension, working
- memory, perceptual reasoning ( among others)
intelligence quotient
assesment
- 70% used as cut diff for intellecutal
- mean = 100
- SD = 15
IQ: verbal comprehension
vocabulary subtest: what is garrulous?
similarties subtest: how are capitalism and socialism alike?
comprehension subtest: what should you do if you find someone's wallet in the store
information subtest: who wrote faust
IQ subscale: Perceptual reasoning
accuracy and speed
- boxes and shi
IQ subscale: perceptual reasoning
this one is not timed..
colorful shapes
IQ subscale: working memory
Digits forward subtest: 3-2-7-6-9-4-1
digits backward subtest: 7-9-4-5-8-2-6
letter-number sequencing subtest: 6
-m-8-a-5-r-1
assessing intelligence in infants/toddlers
track block
- hold in hand
- change from hand to hand
- search for it when covered
- search in different places
- say "block"
- request block
- reqyuest block nively
- make sure mom sees how awesome block is
- tell a story about how awesome block is
importance of profiles
even if you believe in "g", the most helpful information as a clinician is strengths and weaknesses, evryone has them, some are more pronounced than others
critiscisms of intelligence tests
cultural and socioeconomic states bias (SES)
language and content bias (SES)
tests reflect the culture of the people who wrote, administer, and take it
sterotype threat
steele and aronson, 1995
- do worse on same material when you tell them its intellidence and they r in a group that sterotypcially has lower intelligence
intellectual potential changes over the life span
can ones IQ increase or decrease -> yes!
aptitude test
measures cogntiive ability
- fluid
- SAT
- purported to be a measure of general cognitive abilities
achievement test
measures of learned cognitive abilities
- ACT
- Crystalized
benefits of testing and admissions
-metric by which universities can compare across schools
drawbacks of testing and admissions
cultural bias, test prep and SES bias, writing?
motivation
activates (energizes), directs (guides) and sustains (help persist) behavior. it involves:
needs and drives
needs
internal physiological or psychological driving force that motivates ppl to act
drives
internal tension that arises from an unmet need
- want to fulfill them
physioloigcal need
ex. warmth
drive: you feel cold (unmet need), are compelled to find heat or block cold
action: pull your hood over ur head
psychological need
ex. love
drive: you feel lonely (unmet need), are compelled to seek affection from others
action: swipe right
maslows hierarchy of needs
if you dont have the basic needs, you cant meet the ones above it
- psychological needs
- self-fullfillment needs, best self
extrinsic psychological motivations
you are motivated to act by the presence of reward/punishment
- rewards and punishment canbe used to shape, or control behavior
intrinsic motivation
you are motivated to act because the action itself is rewarding, enjoyment of action itself
self determination theory
theory of intrinsic motivation, posits that the introduction of extrinsic motivation undermines intrinsic motivation
- ofc behaviorists disagree
deci 1971
3 sessions, 2 groups, working on the same puzzle
- 2nd session- one group offered monetary reward for completing puzzle(reward group), other group given nothing, unaware of any rewards (control group)
-3rd session: no rewards offered, both baseline
what happened in the 2nd session, 3rd?
- reward group worked harder in second session, but not as hard as non-rewarded group in 3rd session (with noreward)
deci 1971 follow up
field study of volunteer workers at college newspaper, same design, same findings
- other studies have shown that ppl given money find puzzles less interesting
- ppl given money work on puzzles less in free time after task
self-dtermination theory
ppl have innate tendencies for growth and development, rather than being a pdt of their environment (rather than how we are reinforced)
self- determination
decisions based on choice and free will, without external influence
intrinsic motivation (self determination theory)
doing an activity because it is interesting, not because of an external influence
self determination theory needs
according to SDT, these needs are essential to growth and well being
- autonomy
- relatedness
- competence
autonomy
need to actively determine one's own
- we make our own decisions about what to do next
relatedness
need to care for and relate to others
competence
need to control outcomes, predict environment- we can control our outcomes, accomplishment is possible
need for autonomy
feeling that you are acting on your own volition(free will)
facilitated by: abiliity to make choices, involvement in task
undermined by: external pressure, punishment, deadlines, surveillance
need for relatedness
feeling cared for, feeling connected to, sense of belonging with others (care even on worse day)
faciliatted by:
- unconditional empathy, warmth (realtionship is not dependent on how you act on a certain day)
- secure attachments to others
undermined by:
- cold interactions
- controlling relationships, dependent on expectations, enough talking, attention
need for competence
you feel like you can accomplish the task in front of you
- sense of effectiveness and competence in ones context
faciliatted by: optimal challenge(just hard enough so that if they work the can achieve)
-**informational rewards** (not all external is bad, can help with intrinsic)
-**positive feedback?**
undermined by:
- non-optimal challenge
- *negative feedback?**
informational feedback ( rewards and intrisic motivation)
if you are genuinely intersted in learning, getting information is rewarding (positive motivates you )
positive feedback( rewards and intrisic motivation)
promotes competence, if you do something, sometimes you dont know if you r successful without some feedback
rewards that undermine intrinsic motivation
controlling or contingent rewards ( bad, takes away intrinsic interst, good is like "yay u got it" curveball example)
- if you do X, then you will get y
punishments, negative feedback
- punishments undermine all aspects intrinsic motivation
applications to others fields - education
montessori scools,
intrinsic motivation and hig-stakes testing (ultimate extrinsic?)
application to other fields -sports
players enjoy sport more if coaches promote learning actiivty, self and team improvemnt over winning
does intrinsic motovation exist? (no)
behaviorists: say there is no such thing as intrinsic motivation, ail better explained through sternal motivators, "all intrinsic canbe explained extrinsically"
does intrinsic motovation exist? (yes)
theories of intrinsic motivation acknowledge that extrinsic motivation exists
- but intrinsic motivation is better and is undermined by extrinsic rewards
communication is beautiful
babies are native speakers in twp yuears (.. and babies r dumb)
communication
the use of language, gestures, faical expressiooons to exchnage information
language
a system for exhcnaging information
speech
the ACT of vocal communication
tracing a communication interchange
sound travels in the ear, the ear translates it into signals(eletrical)
- brain filters human speech from noise
- bottum-up orocessing and top down processing (both happen at the same time)
bottom-up processing
takes sound bits and turns them into words, and then phrases
top-down processing
takes previous knowledge of concepts and applies them to sound combinations
tracing a communication interchange
the brain thinks about the information and formulates a response
- massive coordination of face, hands, body posture, lungs, lips, tongue , jaw ,throat, to give response
- sound then travels to the other persons ear
- this happens automatically
language/ communication in the brain
- major debate: whether language is modular in the brain, o r is it distributed throughout
- chomsky, pinker, and others argued for distinct laguange areas in the brain
modern research: systems/networks rather than areas
phonemes (component of language)
smallest component of a language
- in essence, a sound (b.k.t.o, th)
- rarely carry meaning in isolation (I,s(plural), a
- you lose the ability to percieve some phonemes (when we are babies if theyre not used in our native language)
phoneme development
vocal exploration
- baby can barely use her lips, so she squeals the phonemes she can make
- eventually , you start to approximate the sounds in your native language
phoneme development - Babbling
ex. 2- "Dada:
language - morphemes
smallest meaningful unit of language
- sassafrass is a morpheme
- confusing- the -s in cats is a morpheme, but not in sassafrass
typically root word and its affixes. Example:
- denationalization ( 5 morphemes)
- de, nation, al, ize, ation
- nation, national, nationalize, nationalizatioj
prefixes and suffixes S to make something plural
- only a morpheme if it changes meaning ed to make past tense
morphemes - overgeneralization
-kids learn rules and exceptions to the rule in steps
(learn exceptions first, but over time, they learn the rule ans start saying things wrong)
1. kids pair a word with a meaning before learning the rule (broke means break in the past)
2. then kids learn a rule (-ed means past tense, breaked, and overgeneralize rule to every circumstance) ("broked")
3. then kids learn the exception to the rule, and there are a lot in english (broke is an excpetion to the -ed rule)
language lexicon
- this is a fancy word for vocabulary (word that relates to some sort of concept, could be one to multiple morphemes)
- this is directly related to concepts
- the total lexicon of a language is always changing
- new: looks maxing, glow-up, vibe-coding
- dead: sternforemost, snollygoster, (scrupulous politician - just dont use anymore)
- words with added meaning: sigma
language - syntax and semantics
closely realted
syntax
is the structure of language- how we order words to great meaning (like grammar)
- sentnece can mean something different depending on arrangement of words
- chomsky argued for a universal syntax, or rules that are present in all languages
- syntactic rule example: recursion(how to add emphasis)
semantics
is how words, phrases, and sentences communicate meaning
- progress (n) vs. progress(v)
- differnet parts of speech
- semantics operates at multiple levels
- lexical sarcasm(say one thing, mean the opposite)
- syntactic
- irony
- synatx without semantics (means nothing)
- colorless green ideas sleep furiously
communication - prosody
patterns of stress and intonation in a language
- can change the meaning of words (progress)
- can add addiotnal information to a word
- bears calm(chicago) vs. scream (threat)
- can structure a conversation ( just by rising the end of your statement, you can turn it into a question)
communication - gestures
- beats (bounce hands along with what youre syaing)
- iconic gestures : gesture resembles object (ex. heart)
- emblems- gesture represents a word (ex. thumbs up)
- metaphoric gestures- abstract ideas/concepts (ex. weighing options ( move hands up and down))
what is the purpose of gestures
ppl gesture even when on the phone
- for us or others?
language acquisition theories - behaviorists
skinner et al.
- language is completely learned, taught
language acquisition theories - nativists
chomsky, pinker
- the ability to understand and communicate through language is innate
- language "module" or "organ" in the brain
language acquisition theories -interactions
bruner et al.
- nature and nurture (interplay)
language/communication explosion
9-12 months, first words
1-1.5 years
- several words, hard to understand
- babbles with prosody
1.5-2 years
- puts words into simple phrases
- articulation improving
2-3 years
- 3 years... full conversations
social cognition
- how we, as individuals, process social information
- thinking fast and thinking slow(about ourselves, others)
- origin of our social behaviors...but how our own social behaviors influence our social thinking is also intersting ( see cognitive dissonance)
fundamnetal attribution error
tendency to make situational attributions about yourself,,, but dispositional attributions about others
actor vs. observor perspectives
- you view your own behavior in multiple contexts
- but you tend to view others only in a specific context
- therefore, you are more likely to view what you see as an attribute of their who they are ("they r just a bad driver")
- example - zoom meeting
og study - jones and harris (1967)
- participants listened to confederates make pro-castro or anti-castro arguments
- one group was told the speakers chose their stance
- the other group was told that it was a coin flip, or sometimes a class assignment
- partcipants then rated how much they belived that the speakers were pro- or anti-castro
attitudes
feelings that predispose our reactions to a situation
- attitudes are good predictors of behavior (most of time)
- biases and stereotypes are examples of attitudes
stereotypes
-characterstics attributed to people because they are members of a group
- attitude that is often overgeneralized, inaccurate, and inflexible
- save cognitive "energy" by simplifying a situation (sound familiar)
* leads to prejudice and discrimination
