Extraversion and Reward-Related Processing: Probing Incentive Motivation in Affective Priming Tasks

Based on an incentive motivation theory of extraversion ( Depue & Collins, 1999 ), it was hypothesized that extraverts (relative to introverts) would exhibit stronger positive priming effects in affective priming tasks, whether involving words or pictures. This hypothesis was systematically supp...

Description
Summary:Based on an incentive motivation theory of extraversion ( Depue & Collins, 1999 ), it was hypothesized that extraverts (relative to introverts) would exhibit stronger positive priming effects in affective priming tasks, whether involving words or pictures. This hypothesis was systematically supported in four studies involving 229 undergraduates. In each of the four studies, and in a subsequent combined analysis, extraversion was positively predictive of positive affective priming effects, but was not predictive of negative affective priming effects. The results bridge an important gap in the literature between biological and trait models of incentive motivation and do so in a way that should be informative to subsequent efforts to understand the processing basis of extraversion as well as incentive motivation.
