Analysis of WAIS-R factor patterns by sex and race.

Factor analyses of WAIS-R standardization data for samples grouped by sex and race (Black-White) produced congruent factors for the various samples and offered good support for Wechsler's two-scale division of the subtests. The factor structures for males and females produced some interesting differences across the age range that were related to sex-related findings in studies of patients with unilateral brain damage. Additionally, Black males and Black females seemed to use different strategies for solving Wechsler's verbal and nonverbal subtests.
