The origins of extraversion: joint effects of facultative calibration and genetic polymorphism.

Personality & social psychology bulletin - 1 Mar 2011

Lukaszewski Aaron W, Roney James R

Abstract excerpt

The origins of variation in extraversion are largely mysterious. Recent theories and some findings suggest that personality variation can be orchestrated by specific genetic polymorphisms. Few studies, however, have examined an alternative hypothesis that personality traits are facultatively calibrated to variations in other phenotypic features, and none have considered how these distinct processes may interact...
