Abstract:
Standardization data for the Kaufman Adolescent and Adult Intelligence Test (KAIT) were used to examine white-black and white-Hispanic differences on the Horn-Cattell crystallized and fluid constructs at several age groups across the broad 11- to 94-year span. Samples included 1,547 white, 241 black, and 140 Hispanic persons. Multivariate analyses with educational attainment covaried yielded only one significant finding: the white-black difference on the Crystallized Famous Faces subtest became smaller with increasing age.
