Abstract
Normative data was collected on the modified form of the Wisconsin Card Sorting Test (WCST) for children 6 to 9 years old. Thirty children at each age level (120 total) were administered the WCST, the Peabody Picture Vocabulary Test-Revised (FPVT-R), and the block design subtest of the WISC-R. A simple concept formation task was also administered to in sure all the children had the concepts color, form and number. Developmental changes in flexibility and solving skill were investigated. Performance on in problem the WCST was also compared with intelligence and mental age scores on the PPVT and block design subtest.
The number of categories obtained and the total number of errors made on the WCST were significantly related to age. However, no particular type of error could be identified as decreasing significantly as the age of the subjects increased. Correlations between intelligence and WCST performance were low. Correlations between mental age scores and WCST performance were significant but only accounted for nine percent of the variance. Mental age scores on the PPVT and the block design subtest were equally correlated with WCST performance.
A new scoring system was devised for the modified form of the WCST. This, and related issues were discussed.
