  1. Intelligence http://content8.clipmarks.com/blog_cache/www.sciencedaily.com/img/BB42D239-0308-460C-B1DF-8E84149639BA

  2. Ways of Defining Intelligence • Consisting of: • Capacity to learn from experience • Ability to adapt to environment • Metacognition: • Ability to understand and control your own thinking • Ability to deal with complexity • What intelligence tests measure • Cultural definitions

  3. Early Measures of Intelligence • Two approaches: • Galton – sensory-based

  4. Early Measures of Intelligence • Two approaches: • Binet – scholastically-based • Intelligence quotient http://imjustaguy.files.wordpress.com/2008/05/iq_bell_curve.gif

  5. Current Intelligence Tests • Stanford-Binet • Wechsler (see handout) • Verbal score • Performance score • Overall score

  6. Debated Questions about Intelligence • Is intelligence singular or multiple? • Is intelligence inherited? • Are intelligence tests biases?

  7. Spearman- the “g”factor • Factor Analysis

  8. Arguments against a general intelligence factor • Architecture of the brain – modularity • Artificial Intelligence research • Most IQ studies done on middle-class Americans • IQ tests do not test practical intelligence

  9. Gardner- Multiple Intelligences • Linguistic • Logical-Mathematical • Spatial • Musical • Bodily-kinesthetic • Interpersonal • Intrapersonal • Naturalist

  10. Gardner’s Criteria for Identifying Intelligences • Brain damage • Exceptional individuals • Core operations • Developmental history • Evolutionary history • Supportive evidence from cognitive-experimental research • Supportive evidence from psychometric tests • Symbol system

  11. Biological Basis of Intelligence • Size of brain • Speed of nerve conduction • Efficiency of brain • Twins studies • Can intelligence change over your lifetime?

  12. The Bell Curve & Social Intelligence • The Bell Curve • Intelligence is a single property • Intelligence is distributed in the population in a bell curve • Intelligence is inherited • Low intelligence leads to social pathology • Implied: blacks more likely to have low IQ than whites • Social Intelligence • One important type of intelligence ignored in psychology

  13. Race and Intelligence • Problems with arguments • Race is a social construct

  14. Culture and Intelligence
