| Abstract: | 270 Black and 270 White children (ages 6–16.5 yrs) drawn from the national stratified random sample used in the standardization of the WISC-R were matched on age, sex, and WISC-R Full-Scale IQ to facilitate investigation of the patterns of specific cognitive abilities, as measured by the 12 subtests of the WISC-R, between the 2 racial groups. Multivariate analysis of the patterns of subtest differences between Whites and Blacks and group comparisons on 3 orthogonalized factor scores (Verbal, Performance, Memory) showed small but reliable average White–Black differences in patterns of ability. The IQ-matched racial groups showed no significant difference on the Verbal factor; Whites exceeded Blacks on the Performance (largely spatial visualization) factor; Blacks exceeded Whites on the Memory factor.
