Abstract

|
Investigated in this study were the effects of intelligence, diagnosis, and anxiety on the level of performance on the KWIS subtests of Arithmetic and Digit Span.
Two groups of 40 each, one schizophrenic and one neurotic were further divided on the basis of anxiety (Taylor´s Manifest Anxiety Scale) and intelligence level (overall KWIS score). Analysis of variance was used to evaluate effects of intelligence, anxiety, and diagnosis on Arithmetic, Digit Span, and the relationship between the two.
Intelligence level was positively related to Arithmetic Score, but not to Digit Span Score. High intelligence was also associated with Arithmetic performance superior to D;4t Span performance.
Anxiety did not have a direct effect on either Arithmetic or Digit Span, but it was associated with the relationship between the two. That is, higher anxiety levels were associated with Arithmetic superior to Digits.
Diagnosis was neither, directly related to the two scores nor to the relationship between the two. However, almost significant was the triple interaction of diagnosis, anxiety, and intelligence.
Schizophrenics low on intelligence and low on anxiety demonstrated Digit Span superior to Arithmetic. Neurotics who were bright and anxious demonstrated the more typical pattern of superior Arithmetic to Digit Span.
Schizophrenics seem to perform better on Arithmetic under effects of high anxiety, whereas neurotics perform equally well on Arithmetic tests under both conditions of high and low anxiety. The presence of anxiety in the schizophrenics is a good sign, indicating that the person has not reached a chronic state.
It also suggests more resources and ego strength than the low anxiety schizophrenic.
