Abstract
"This experiment was performed to evaluate the effects of anxiety (Taylor-scale scores) and defensiveness (MMPI K- scale scores) on intellectual performance (ACE scores and grade-point averages). The results failed to show significant changes in these two measures of intellectual performance as a function of anxiety. However, Ss low in defensiveness were found to perform significantly more poorly on the ACE than did all other Ss in the K-scale distribution. A similar trend was found for the grade-point averages. The results were discussed in terms of the adverse effect of the self-criticism of low K Ss on their performance in highly motivating situations. ".
