Document Summary
Williams syndrome: happy, genetic glitch that impairs cognitive abilities and yet leaves great talents. Intelligence: ability to direct one"s thinking, adapt to one"s circumstances, and learn from one"s experiences. Alfred binet and theodore simon developed 1st intelligence test to identify children who needed remedial education: measure aptitude apart from achievement, william stern coined mental age . Intelligence quotient (iq: lewis terman developed iq test by revising binet-simon scale. Wiliam stern coined this term too: average iq is 100 and about 70% of people have iqs between 85 and 115. Most widely used intelligence tests today are the stanford-binet and the wais. Eye gaze may be the best predictor of intelligence. Charles spearman set out to discover if there was a hierarchy of ability, and found correlations (thought not perfect) among many cognitive tasks. Louis thurston felt that the clustering of correlations disproves the general ability theory and argued for a few primary mental abilities that were stable and independent.
