The relationships between intellectual and demographic variables of the Wechsler Intelligence Scale for Children-Revised (WISC-R) were examined. Subjects were 2,200 children in the WISC-R standardization sample. Four multiple regression analyses were performed between Full Scale and Verbal Comprehension, Perceptual Organization, and Freedom from Distractibility (FFD) factor intelligence quotients (IQs) with 14 dichotomous demographic variables. Two canonical analyses were conducted between the demographic variables and sets of IQs and subtests, respectively. A general intelligence function, influenced by ethnicity, socioeconomic status, and region, was evident from both regression and canonical analyses. A weaker gender related attention dimension also emerged from the canonical analyses. The results provide a simultaneous multidimensional picture of the WISC-R intellectual and demographic variables and support the validity of the three factors suggested by A. S. Kaufman (1975), especially the FFD factor. Six tables present study data. (SLD)
