Researchers have suggested that task performance is often dependent upon the congruence of cognitive style and task. To explore this suggestion, 44 female and 4 male undergraduates were administered the Cognitive Style Analysis, the Closure Flexibility, the Composite Gestalt Completion Test, and the Vocabulary subtest from the WAIS. Specifically, four hypotheses were tested: (1) that participants with an analytic style will perform better than those with a wholistic style on the Closure Flexibility; (2) that participants with a wholistic style will perform better than those with an analytic style on the Composite Gestalt Completion Test; (3) that participants with an intermediate style will outperform persons with an analytic style on the Composite Gestalt Completion Test; and (4) that intermediate scorers would perform better than those with a wholistic style on Closure Flexibility. Only the second hypothesis was supported, so results provide only minimal support for the effect of match or mismatch of cognitive style and task performance.
