EFFECT OF INTELLIGENCE, ANXIETY, AND DIAGNOSIS ON ARITHMETIC AND DIGIT SPAN PERFORMANCE ON WAIS

Tested 40 schizophrenics and 40 neurotics using WAIS scores, with Arithmetic (A) and Digit Span (DS) subtest scores subtracted, as a measure of IQ, and the MMPI as a measure of anxiety. Results suggest: (1) the intelligence level of S must be considered to interpret the relationship between A and DS; (2) the relationship between A and DS is a better indication of anxiety than the level of DS alone; (3) DS well below A may be a function of anxiety or intelligence and the affect is enhanced when S is bright and anxious; and (4) chronic or low-anxiety, dull schizophrenics and dull but not anxious nonschizophrenics show out-of-pattern relationship of DS above A.
