Problem solving as a function of extraversion and masculinity

Abstract

The present study aimed at investigating the differences in performance on five problem solving tasks in terms of extraversion-introversion and masculinity-femininity of 48 University males and females assigned to meet the requirements of a 2 × 2 × 2 between group factorial design. While the first four problems were solved with a time limit, and then the scores combined to obtain a composite index, in the fifth, the index of performance was both number of trials and time taken to solve the problem. The data were analyzed by ANOVA. The findings are: (i) Introverts are superior to extraverts on the composite performance index of the first four problems. (ii) On the fifth problem (i.e. problem squares) the male subjects performed significantly better than their female counterparts. (iii) A highly significant personality × sex role × sex interaction revealed that in males extraversion determines the level of performance, i.e. introverts perform better than extraverts regardless of their scores on masculinity-femininity; and in females masculinity boosts the performance of the extraverted group, and femininity hinders the performance of this group. (iv) When males and females were matched on E-I and M-F, the expected sex differences failed to emerge.
