Galton's Anthropometric Approach

  • anthropometric: the method of measuring physical and mental variations in humans
  • the idea that people with heightened sensory abilities were able to take in more information and thus, were smarter
  • found no correlation and was thus abandoned



  • intelligence: was defined by Alfred Binet as the ability to think, understand, reason, and adapt to overcome obstacles


Alfred Binet

  • tests given to children were meant to reflect their mental age
  • compared mental age to actual age to determine how intellectual advanced that child was


Standford-Binet Test

  • Binet's test adapted in the US
  • Stanford-Binet test: a test intended to measure innate levels of intelligence
  • differed from Binet's original test who viewed his test as a measure of a child’s current abilities, not as a measure of an innate capacity


Intelligence Quotient (IQ)

  • intelligence quotient (IQ): is calculated by taking a person's mental age, dividing it by his chronological age, and then multiplying by 100
  • did not make sense when applied to adults
  • created deviation IQ for adults, which compared to average scores of the same age


Wechsler Adult Intelligence Scales (WAIS)

  • the WAIS provides a single IQ score for each test taker—the Full Scale IQ —but also breaks intelligence into a General Ability Index (GAI) and a Cognitive Proficiency Index (CPI)
  • GAI is computed from scores on the Verbal Comprehension and Perceptual Reasoning indices
  • CPI, in contrast, is based on the Working Memory and Processing Speed subtests


Raven's Progressive Matrices

  • previous tests were often culturally biased which did not properly represent a person's intelligence
  • Raven's Progressive Matrices: an intelligence test that is based on pictures, not words, thus making it relatively unaffected by language or cultural background



  • eugenics: the idea of "good genes"
  • people of other cultures performed worse than Western Caucasians which further supported this idea
  • however, this can be attributed to other factors such as lifestyle and cultures


Stereotype Threat

  • stereotype threat: occurs when negative stereotypes about a group cause group members to underperform on ability tests
