Trait extraversion has been theorized to emerge from functioning of the dopaminergic reward system. Recent evidence for this view shows that extraversion modulates the scalp-recorded Reward Positivity, a putative marker of dopaminergic signaling of reward-prediction-error. We attempt to replicate this association amid several improvements on previous studies in this area, including an adequately-powered sample (N = 100) and thorough examination of convergent-divergent validit

For several years, theory and research in Personality Neuroscience has linked dopamine function with various aspects of personality and individual differences. This literature builds on research in basic neuroscience concerning the role of dopamine in behavior and experience, with the aim of understanding the ways in which this neurotransmitter system influences regularities in behavior and experience. We organized this special issue on “Dopaminergic Foundations of Personalit

Reward processes have played an increasingly visible role in theories of extraverted personality. Reward processing is usually conceptualized in terms of the brain system responsible for generating incentive motivation and behavioral approach of rewarding stimuli, as in theories by Jeffrey Gray and Richard Depue. Recent increases in the accessibility of neuroscience methods have accelerated our understanding of the relationship between extraversion and neural processing of re
