Abstract
Objective:
The aim of this study was evaluation of the association between the scores of Wisconsin Card Sorting Test (WCST) and Wechsler Intelligence Scale for Children - revised form (WISC-R) among children with and without symptoms of learning disability (LD). Also the correlation between WCST and WISC-R subscale and subtest scores of the children with LD symptoms were examined.
Method:
61 children (10 girls, 51 boys) with learning disability symptoms were compared by their WCST scores with 10 girls and 51 boys without any LD symptoms. Differences between two groups were analyzed by using ANCOVA. Furthermore, the correlation between WCST and WISC-R scores of children with LD symptoms were examined.
Results:
10 out of 13 WCST scores were found significantly different between two groups in favor of children without LD symptoms. Moderate correlations were observed between a couple of WISC- R and WCST scores.
Discussion:
Results indicated that WCST scores of children with LD symptoms were significantly different from children without symptoms. Also there were only a few correlations between some scores of WISC-R subtests and subscales and WCST and this fact indicates that these two tests assess different functions and should be used together in assessing mental functions.
