Abstract
Although the theory has been widely adopted that Extraversion reflects individual differences in brain systems governing reward sensitivity, the evidence base for this theory is surprisingly thin. A few fMRI studies have correlated brain activity in response to monetary rewards or pleasant emotional stimuli with Extraversion, but their samples sizes have generally been very small ( N N > 90), we show that Extraversion (and no other of the Big Five) is associated with neural sensitivity to monetary reward in a simple reinforcement task (guessing whether a computer-generated number will be high or low) and in a decision making task assessing delay discounting (choosing between smaller, sooner rewards and larger, later rewards). These studies provide strong evidence for the theory that Extraversion reflects reward sensitivity.
