Intelligence Flashcards
Intelligence
Ability to use one’s mind to solve novel problems and learn from experience
What was the original purpose of IQ tests?
Originally developed to help underprivileged children succeed in school
Binet and Simon
Their goal was to develop an objective test - an unbiased measure of child’s ability, independent of prior educational achievement.
What is the best way to see if a child is developing normally?
Examine ratio of child’s mental age to physical age - their intelligence quotient.
Ratio IQ
Mental age/physical age x 100
Only works with children b/c of smaller age range
Deviation IQ
person’s test/average score in age group x 100
Doesn’t work with children because they score the same as adults
Wechsler Adult Intelligence Scale (WAIS) (WISC for children)
Tested verbal comprehension, perceptual reasoning, working memory and processing speed
Verbal comprehension
How words relate to each other
Perceptual reasoning
Visual problem solving
Working memory test
How much info you can hold and manipulate
Processing speed
Detect visual details quickly
What does intelligence predict?
Excellent income
There’s a role of education (r = 0.5 between intelligence and academic performance)
Healthier/longer life
Spearman’s two factor theory
Person’s performance on a test is due to a combination of general ability (g) and skills that are specific (s) to the tests
What did Thurston claim?
No such thing as g; instead there’s a few stable mental abilities: primary mental abilities that are neither general or specific. There are 7 of them and they differ in strength between individuals.
Word fluency
Ability to solve anagrams/find rhymes
Numerical ability
Make mental and other numerical computations
Spatial visualization
Visualize complex shape in various orientations
Associative memory
Recall verbal material and learn pairs of unrelated words
Reasoning
Induce general rule from few instances
Three level hierarchy
Closer to reality than other models of intelligence. There’s a general ability (intelligence) which is made up of a set of middle-level abilities, which are made up of a large set of specific abilities unique to tasks. Incorporates Spearman and Thurston’s claims.
What are middle level abilities?
There’s data based (Carroll) and theory based (Sternberg) approaches
