Document Summary

8 year old solving 10 year old problems, mental age=10. Intelligence quotient (iq): iq=(mental age/chronological age) x 100. Stanford-binet: verbal items - > single iq score. Arthur otis: wwi; army alpha- verbal; army beta- non-verbal (mazes, puzzles) Wechsler: wais, wisc, wppsi; used today in north america. Psychometric approach: psychometric: identify & measure abilities that underlie individual differences in performance; measurement-based map of mind. Charles spearmen: verbal acuity cluster & mathematical reasoning cluster=correlated- 0. 4-0. 5; g-factor: (general intelligence)- performance in mathematical course would depend mainly on general intelligence, but also specific ability to learn math. Thurstone: primary mental abilities- 7 distinct abilities; performance on verbal/mathematical task=influenced more by specific skills represented in relevant cluster than by any g-factor. Crystallized intelligence (gc): ability to apply previously acquired knowledge to current problems; ability to retrieve previously learned information & problem solving schemas from long-term memory.
