Reanalysis of Wakefield and Carlson's data confirmed canonical correlations of.84 and.69, but analysis of redundancies revealed that only 34% of the total WISC subtest variance is redundant with the ITPA and 39% of the ITPA subtest variance is redundant with the WISC. This indicates that there is not the high degree of redundancy between the two instruments that the authors had claimed and, therefore, use of one of the tests should not preclude use of the other one. It also was pointed out that results for a group of subjects may not apply in individual cases.
