Document Summary

Intelligence: what is it, tons of things involved, a host of abilities (memory, creativity, etc, what a test measures, but tests can be misleading. Psychometric approach: galton, 1869 -> relatives of intelligent people, thinks if you are related you must be successful, genetics, thought it was hard wired into you. Standardize test: get age norms (mean performance for scales on test and age, assign new test score to mental age group according to norms. So if child performs at level of average 5 year old: terman (& stern, ma = 5, developed iq, adapts binet scale for use in the u. s. a. while at stanford, stanford-binet is widely used. Iq scored turn out to be normally distributed. Test concerns: reliability: consistency of measurement, test - retest, r = 0. 8 to 0. 95 for standard-binet & wais-iv, validity: does test measure what it"s supposed to, r with achievement range from 0. 3 to 0. 7.
