Detailed explanation-1: -Spearman’s two-factor theory proposes that intelligence has two components: general intelligence ("g") and specific ability ("s"). To explain the differences in performance on different tasks, Spearman hypothesized that the “s” component was specific to a certain aspect of intelligence.
Detailed explanation-2: -Charles Spearman inferred the existence of a “g” (or general) factor in intelligence from the observation that. people who do well on one intellectual test also do well on other intellectual tests.
Detailed explanation-3: -Summary. The Theory of General Intelligence proposes that there is only one intelligence, measured by a single ‘g factor’ that underlies performance in all cognitive domains. Performance in different cognitive tasks are interrelated, all hinging on the single ‘g factor’. Key Points.
Detailed explanation-4: -The early 1900s saw Charles Spearman using a mathematical approach to the question of measuring human intelligence. Using statistical factor analysis Spearman identified g, a single underlying intelligence factor he believed accounted for the variety of observable abilities.
