The present study was conducted to investigate attention problem in ADHD, LD, Depression, and Tic disorder. KEDI-WISC and TOVA were administered to 4 diagnostic group(ADHD=15, LD=15, Tic disorder=15, Depression=15). On KEDI-WISC, FSIQ, VIQ, PIQ and 11 subtest measures and 4 factors by Bannatyne classification(1974) were used to analyse differences among four groups. On TOVA, 4 variables(omission error, commission error, responce time for correct response, variability for correct response) were analysed. The Results showed significantly lower level of performance of ADHD group and LD group than the other two groups on coding of KEDI-WISC, and showed siginificant difference among four diagnostic groups on three variables of TOVA except for commission error. In order to specify the similarity and the difference among the cognitive ability of each diagnostic group, Discriminant analysis was conducted. In this analysis, 11 subtest of KEDI-WISC and 4 variables of TOVA were used as independent variables and each diagnostic group was dependent variables. As a result of discriminant analysis, overall percentage of correct classification was 68.33%. The clinical implifications, and limitations of the present study were discussed.
