Abstract: | 91 children (mean age 11.5 yrs), screened for absence of emotional and educational disabilities, were tested on the WISC-R and examined for significant subtest variability. Arithmetic, Digit Recall, Comprehension, and Coding differed significantly from the grand mean of all subtests. In a 2nd analysis, subtest variability was examined relative to Ss' sex, age, and overall IQ. Sex differences occurred on Information, Picture Completion, Arithmetic, Coding and Digit Recall. Age differences occurred on Information and marginally on Performance IQ. Sex and Age interacted on Performance IQ, and Sex and IQ interacted on Coding. It is suggested that the absence of sex-specific norms and separate norms for Canadian children may lessen the clinical interpretability of subtest differences on the WISC-R.
