Measured complex mental aciviies (memory and reasoning), test incl verbal and noverbal items requiring thought and judgement, also associated diiculty with age. Lewis terman, brought test to us => standord-binet intelligence scale. Factor analysis = ideniied sets of test items that cluster together , called factors. High performance on one item should do well on others in the same cluster. General intelligence, g: found all test items correlate with each other => common underlying g, central and supreme. Test items not perfectly correlated => varied g contribuion => speciic intelligence unique to each or a set of similar tasks. Thurstone: quesioned importance of g, separate unrelated factors exist called primary mental abiliies.
