Comparative aspects concerning the effects of extraversion on performance in a cognitive task in competitive and cooperative conditions

Abstract

This study aims how extraverts differ by introverts in cognitive performances when they work in different conditions of in-group interactions, namely in-group cooperative or in-group competitive context. The participants were systematically trained to work by in-group cooperation or competition. The control group was individual activity. Results indicated that in competitive group condition extraverts had higher performance and in cooperative group condition introverts performed better. Possible explanations emphasized the stimulating effect induced by in-group competition on extraverts and by the fact that introverts have better results in cognitive task in non-tensity environment such as in group cooperative activity. Size effects were small.
