Auditory and visual factors of intelligence

In a sample of 241 convicts, most of whom were between 20 and 35 years of age, a sample of 18 primary mental abilities was factored to explore the idea that in performances that are believed to indicate human intelligence there are organizations among visual and auditory functions that operate independently from the relation-perceiving and correlate-educing functions of fluid and crystallized intelligence. Objectively rotated results suggest that, indeed, reliable overlapping (common-factor) functions of Auditory Acuity (Ac), Auditory Organization (Ga), Visual Organization (Gv), Acculturational Eduction (Gc) and Fluid Eduction (Gf) represent separate components of individual differences in performances on intellectual tasks broadly conceived.
