Cattell, John L. Horn and John B. Carroll, the Cattell–Horn–Carroll theory is regarded as an important theory in the study of human intelligence.

It is a variable that summarizes positive correlations among different cognitive tasks, reflecting the fact that an individual's performance on one type of cognitive task tends to be comparable to that ...
g and s. Spearman's two-factor theory proposes that intelligence has two components: general intelligence ("g") and specific ability ("s"). [7] To explain the differences in performance on different tasks, Spearman hypothesized that the "s" component was specific to a certain aspect of intelligence. [2] Regarding g, Spearman saw individuals as ...
Contemporary theories about intelligence can be divided into two classes: psychometric and cognitive. The quantitative approach to intelligence is better reflected in psychometric theories of which Charles Spearman's is an early example. In contrast, cognitive theories such as PASS theory are both qualitative and quantitative.
The concepts of fluid intelligence (gf) and crystallized intelligence (gc) were introduced in 1943 by the psychologist Raymond Cattell. [1][2][3] According to Cattell's psychometrically -based theory, general intelligence (g) is subdivided into gf and gc. Fluid intelligence is the ability to solve novel reasoning problems and is correlated with ...
