Abstract

OBJECTIVES: What are the differences between measuring intelligence with the WISC-R or with the Progressive Matrices Tests? METHODS: 702 children were tested as outpatients of the Child and Adolescent Department of the Psychiatric University Hospital Erlangen-Nuremberg by means of the WISC-R and the Progressive Matrices Tests (CPM and SPM). RESULTS: Highly significant differences in the mean were found. The mean IQ was 10 points higher on the CPM than on the WISC-R but 6 points lower than the WISC-R on the SPM. At 0.67 the correlations between WISC-R and the Matrices Tests were each in the middle high range. Differences between the tests were substantial and remain unchanged despite the recently newly normed SPM.
