What is intelligence?
adapt to environment, think and learn, understand self and others
How did Binet measure intelligence?
Mental age, chronological age, intelligence quotient (IQ)
What is mental age
mental development relative to others
How did Binet calculate IQ?
Mental age divided by chronological age times 100
if a 16 year old scores as well as most 16 year olds, their IQ is ____
100
If a 16 year old scores as well as most 20 year olds, their IQ score is:
greater than 100
If a 50 year old scores as well as most 20 year olds, his IQ is:
less than 100
Ratio IQ
MA/CA x 100 = IQ (no longer used)
Deviation IQ
- IQ relative to others of the same age
- give the test to lots of people (standard or norm)
g
- general intelligence
- we all possess a certain amount of g
Support for g
correlates with: grades, processing speed, general knowledge
Fluid Intelligence
- novel problems / reasoning
- Working memory and processing speed
- stops developing after early adulthood and drops off some
Crystallized Intelligence
- factual
- ex: vocab, math problems, social customs
- increases throughout life and stops around late adulthood
g (general intelligence) is subdivided into:
fluid and crystallized intelligence
Gardner’s view of intelligence:
- 9 types of intelligence : visual-spatial, linguistic verbal, interpersonal, intrapersonal, logical mathematical, musical, bodily-kinesthetic, and naturalistic
Evidence for and against Gardner’s view of intelligence
For: - brain damage (can lose ability in one area but not another)
- Child prodigies (really good at one thing)
Against: often correlated
Sternberg’s Triarchic Theory of intelligence
- based on our ability to succeed/function
- split up into 3 different types: Analytical, Creative, and Practical.
Sternberg’s Triarchic Theory of intelligence - Analytical intelligence
- academic
- related to g (general intelligence)
- ex: performance on standardized tests
Sternberg’s Triarchic Theory of intelligence - Creative Intelligence
- novelty
- related to fluid intelligence
- ex: forgot important equipment, what are the alternatives
Sternberg’s Triarchic Theory of intelligence - Practical Intelligence
- everyday problems, adaptability
- street smarts
- ex: knowing how to work with coworkers
Infant Intelligence
- measured via the developmental quotient and Bayley Scales (OK diagnostic..not great)
Best predictors of Infant Intelligence
Information Processing - attention, habituation, cross modal perception
IQ tests are ____ making them unreliable measures of intelligence
biased
How genetics influence IQ (evidence)
- Biologically related individuals seem to have more closely related IQ measures than adopted people
- Identical twins are more alike in IQ than fraternal twins
