Some areas tested on the wais include: o: vocabulary. American psychologist lewis terman formalized this comparison with the intelligence quotient or ratio iq. The bad thing about the deviation iq is that it does not allow comparisons between people of different ages. Today the most widely used intelligence tests are the stanford-binet and the wais. Intelligence test scores predict a person"s academic performance, job performance, health, wealth, attitudes, and even basic cognitive abilities. Factor analysis- statistical technique used by charles spearman to explain a large number of correlations in terms of a small number of underlying factors. Two-factor theory of intelligence- spearman"s view of general ability and specific skills. Thurstone"s view of primary mental abilities- word fluency, verbal comprehension, numerical, number, space, memory, perceptual, speed, reasoning. Spearman"s two factor theory of intelligence suggested that every task requires a combination of a general ability and skills that are specific to the task.
