Cross-cultural evidence for the fundamental features of extraversion
Lucas, Diener, Grob, Suh and Shao, Journal of Personality and Social Psychology 79(3), 2000, 452-468. Four studies tested whether extraversion facets are linked by reward sensitivity or by sociability, including widely used scales and a diverse sample from 39 nations. Only facets reflecting reward sensitivity loaded on a higher-order extraversion factor, which correlated strongly with pleasant affect. The authors suggest sociability may be a by-product of reward sensitivity.
