Document Summary
To determine intelligence, they examined items correlated with high teacher ratings. Developed the binet-simon test of intelligence, gave a score of the child"s mental level. Modified in the usa to become the stanford-binet test. Adult version is wais-iii and child version is wisc-iii. Iq is child"s mental age divided by their physical age. Sir francis gelton believed intelligence was based on biological differences. He attempted to determine if there was a link between intelligence and the speed of sensory processes, no significant correlation. Charles spearman developed factor analysis to determine if there was a general intelligence that underlays performance in the binet tests. 2 factors influence test performance: general intelligence (g) and specific intelligence (s) Specific intelligence refers to skills that apply directly to the problem being solved. General intelligence correlates positively with the results of all the tests. Cattell developed this idea by breaking g into gf (general fluid intelligence) and gc (general crystal intelligence)
