| Abstract: | Examined discrepancy scores (Verbal IQ minus Performance IQ) for the WISC-R, using the standardization sample--100 boys and 100 girls at each of 11 age levels between 61/2 and 161/2 yrs (2,200 Ss). The occurrence of significant discrepancy scores (Verbal > Performance and Performance > Verbal) was not significantly related to age, sex, or race, although significant relationships were obtained with both parental occupation and intelligence level. The mean absolute discrepancy score (regardless of sign) was about 10 IQ points for each age group, for boys and girls, for Blacks and Whites, and for the different occupational groups. Discrepancy score norms (cumulative distributions) are presented by intelligence level and are interpreted in terms of their clinical significance. Several of these findings closely parallel results of a study of the 1949 WISC by H. G. Seashore (see record 1952-06292-001). (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
