Abstract

Converging evidence from self-report data demonstrated that extraversion and dispositional positive affect are systematically related. Several authors therefore considered positive affect as the conceptual core of extraversion. Because the ventral striatum is regarded as a core region in the physiological basis of extraversion, the present study examines the importance of this neural substrate with a special focus on positive affect. Baseline cerebral blood flow was measured in 38 participants and regressed to the extraversion and dispositional positive affect scales. Partial correlational and indirect-effects analyses indicated that striatal blood flow was no longer associated with extraversion when positive affect was statistically controlled. In contrast, when extraversion was statistically controlled, striatal blood flow was still associated with positive affect. This finding suggests that the striatal region is not a biological basis of extraversion per se. Rather, this region sustains positive affect, which in turn appears to be a core feature of extraversion. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
