Fluid and Crystallized Intelligence and Broad Perceptual Factors Among 11 to 12 Year Olds.

A battery of 36 visual and auditory tests was given to a sample of 113 primary school children. Second-order analysis of the data yielded two well-defined factors representing Fluid (Gf) and Crystallized (Gc) Intelligence and two perceptual factors corresponding to General Visualization (Gv) and General Auditory Function (Ga). Perceptual factors were not clearly separated from broad intellective factors at this age level.
