Relation between the Wais and the Kahn Test of Symbol Arrangement

Abstract

Forty Ss participating in a biodynamic stress study were administered the WAIS and KTSA. Ss were further divided into two groups of 21 and 19 on the basis of their achieving a numerical score on the KTSA above or below 90. Kahn had hypothesized earlier that 90 may be considered the cut-off point between “normal” and “abnormal” Ss. Correlations between the Verbal Performance, Full Scale IQs, and weighted scores of the 11 WAIS subtests and the KTSA numerical score failed to reach the .05 level except in the case of Comprehension for the Above-90 Group (r = .41) and of Information for the Below-90 Group (r = –.57). It was concluded that, since these correlations could have been chance ones in view of the number of correlations, there is no significant relationship between the KTSA numerical score and the WAIS IQs or subtests.
