Intelligence Flashcards
Midterm 2 (83 cards)
intelligence testing: binet background
- higher mental processes -> memory, prob solving, language, judgements
- idea of mental age
- schools found that some students were struggling
○ How they were identifying struggling students: purely based on teachers identifying which students were struggling
intelligence testing: early def mental age
○ What age in these questions are you performing at?
§ Ex: if you’re 5 year old but answering questions like how they’d expect a 7 year old to answer, they’d give you a mental age of 7
Stanford-Binet Intelligence Test
At each age of the test, the average is 100
- If you’re performing at the average age you actually are, you’d have a store of 100
Mental quotient and original intelligence quotient are now outdated bc what a “mental age” is is tricky
Stanford-Binet Intelligence Test: past and present scoring
past: intelligence quotient
- provided 1 general score
now: scores now given based on deviation - where a child scores relative to the average at their age
- We have lots of standardization of how other people your age are performing
- IQ is normed to your age
Wechsler Intelligence Scale for Children (WISC) ( + preschool version)
provides general score plus 5 composite scores
- Developed with a children and adult version
○ Thought that Stanford-Binet test relied too much on words
○ Thought that tests should have non-verbal components
intelligence testing: idea of deviation
- The exact, raw score isn’t actually used
- What’s used is how much you deviate from the average of your age
reliability (consistency)
If you give the same test later, it should be consistent over time
- split-half reliability
- test-retest reliability
split-half reliability
If you look at a score at the first half vs. the second half of an IQ test, you should have similar scores throughout the test
test-retest reliability
○ You get similar scores at two different testing points
○ The further apart in time, the less reliable it is
§ IQ is decent at being reliable even decades later
validity
it’s measuring what we think of as intelligence
- content & construct validity
- predictive validity
content & construct validity
○ Do the questions within the test actually get at intelligence?
○ Does the construction of the test actually get at intelligence?
○ Bring in experts: do you think these questions measure intelligence?
predictive validity
○ It should also predict things that we think are linked with intelligence
§ Academic success
§ Life success
○ What IQ is good at predicting:
§ Military training success
§ High complexity job performance
§ Civilian training success
content-validity bias
○ Is the content of the test equally valid or is there bias?
○ If a question is more likely to have gotten right by a certain group of people, they’ll tweak the test
predictive validity bias
○ Is it equally predictive of outcome in different groups? If I give everyone an IQ test, does it validly predict outcome across different groups?
psychometric appraoch
idea that we can have a construct/idea of intelligence, and that is something measurable and assessable through testing
- We can operationalize intelligence through testing
general intelligence: what it’s comprised of
- crystallized intelligence
- fluid intelligence
- BOTH correlate and contribute to the one, “overall” intelligence
defining intelligence: general intelligence (g)
general intelligence as multiple abilities/properties
- G factor: the overall score you receive from the IQ test
- While you can differentiate between sub-abilities, they’ll all correlate and connect into one overall intelligence
crystallized intelligence
factual knowledge
- What you can learn through schooling/learning
○ Do you know who George Washington is?
- Increases with age
fluid intelligence
intelligence on the spot
- If I give you a list of words, how quickly can you memorize them?
- Decreases in older age
Sternberg’s Model of intelligence
3 parts:
- Analytical
○ What’s measured by typical IQ test
- Creative
○ Thinking of things in new ways, new answers
- Practical
○ Street smarts
○ How quickly are you able to adapt, to go out and be successful in the real world?
Gardner’s Model of Intelligence
~8 types of intelligence that are all distinct from each other
○ Interpersonal
○ Visual-linguistic
○ Logic-mathematical
○ Naturalistic
○ Intrapersonal
○ Visual-spatial
○ Musica
○ Bodily-kinesthetic
- Very influential in schooling
○ When looking at different abilities (eg musical, visual-spatial, etc.), it’s been found that they still correlate to general intellegence
factors related to differences in IQ tests
- genetics
- gene-environment correlations
- environment
genetics (related to IQ differences)
- many look at twin studies
- Monozygotic twins who were raised apart, they’re still quite likely to have similar IQ stores
- Strong evidence that genetics play a role in intelligence
- If you share genetics with somebody, you’re more likely to have similar IQs as them
gene-environment correlations (related to IQ differences)
- If we have a genetic tendency towards wanting intelligence, our environments often warrant that
