Unit 5 Flashcards
What is fluid intelligence?
ability to think on the spot -adaption to novel tasks -(attention) -working memory
What is crystallized intelligence?
-factual knowledge about the world -long-term memory from prior experience -related to verbal ability
Why did Binet create the IQ test?
- ministry of education asked him to find an objective way to determine the kids who were struggling (vs. subjective teachers)
- focused on higher mental processes & age -brought to north america by Louis Terman
- mental age/chronological age x 100
- based on observable behaviours
What is g?
general intelligence -cognitive functioning -think/learn on intellectual tasks *
Binet - qualities of intelligence ?
- based on observable behaviour
- intelligence is different at different ages
WISC?
Wechsler Intelligence Scale for children
- focused less on language
- provides general score plus 5 composite
- (WPPSI - for preschool kids)
- WISC-V up to date one? w/ Carroll’s 3 stratum
Is the WISC or the Stanford-Binet more widely used? Why?
WISC
-subscales & first to use deviation
Do IQ tests have reliability? How do they test this
- split-half reliability - (1st half then compare to 2nd half) -0.8 or 0.9 -yes quite reliable
- test -retest (diff version of same test some time later) -yes reliable - moreso closer together (days/weeks)
When is there less IQ test relaibility?
- if there is longer time between test-retest (ex. years)
- and earlier on in development
T or F?
IQ becomes more consistent throughout development?
T
Do IQ tests have validity? What kinds?
- predictive validity (does it predict other things associated w/ intelligence?) -generally yes
- construct/content validity (is it really measuring intelligence) - hard to know - hard to define intelligence ?
What is the psychometric approach?
- measurement of mental abilities, devising tests to measure a person’s intelligence relative to others
- Stanford-Binet & WISC
What is g?
general intelligence - can be made up of fluid & crystallized & many other mental abilities/processes - but is the 1 thing that underlies skills etc.
What is Three-Stratum Theory of intelligence? Who came up with it?
- breaks g down into categories & abilities - all are related/influence each other - but go into the underlying/overarching g
- John B. Carroll
Which IQ tests/theories are a part of the psychometric approach?
- Stanford-Binet -WISC -WPPI - Three-Stratum Theory of Intelligence
- says it can be measured
What is Sternberg’s Theory of Successful Intelligence?
-intelligence relating to success - not measurable - analytical, creative, and practical (everyday, not measured typically)
What is Gardner’s Multiple Intelligences?
- 8 different
- linguistic, logical-mathematical, spatial abilities, musical, naturalistic, bodily-kinesthetic, intrapersonal, and interpersonal
- domains not necessarily related to each other
What is dizygotic twins?
- fraternal
- share 1/2 DNA
What is monozygotic twins?
- identical
- share all DNA
What are passive genetic effects?
effects of your gense emerge by being raised by biological parents who share those genes (high IQ parents create high IQ environment for their kids)
-not consciously doing it
What are evocative genetic effects?
- child more active role - genes evoke reactions from others
- ex. ask to be read a bedtime story
- evoking reactions
What are active genetic effects?
kid does it on their own -
ex. chooses to read to themselves or at lunch time etc.
* *watch vid
How do they use twins in studies? Intelligence?
- fraternal compared to identical - if more shared traits w/ identical then indicates genetic
- intelligence is more similar for identical than for fraternal who are raised together (shows genetic influence)
How do effects of genes on IQ change over time? Why?
- identical -IQ gets more & more similar with age
- fraternal - IQ gets more different
- b/c choosing your enviro - mono make similar enviro choices
- active (choice) & evocative (influence others) effects
How does school effect IQ? study?
-longer in school the higher IQ - study = kids on birthday edge - 1 yr extra in school makes huge difference in test scores
How does environment effect IQ?
-those who live in the same environment have similar IQ than those who live separately
What was the mindset video?
- 5th graders
- fixed or growth
- did easy puzzle - either praised for ‘smart’ or effort -then did harder puzzle -(said nothing) -after asked which one they wanted to do, easy or hard
- kids with fixed didn’t want to do the harder puzzle (were told ‘smart’ on first one)
- kids w/ growth chose challenging one (we’re praised for effort)
