Quizplus · Accepted Answer

Thurstone's theory of primary mental abilities was a reaction to his observation that the correlations among different mental tasks measured on IQ tests were lower than what would be expected if a single general intelligence factor (g) were to explain cognitive abilities. This led him to propose that intelligence is better understood as multiple distinct abilities rather than a single general ability.
