Abstract: In this paper I discuss how expressive behavior relates to personality and psychopathology, integrating recent findings from my laboratory and the insights of Charles Darwin on this topic. In the first part of the paper I challenge the view, in part espoused by Darwin, that humans are equipped to convey only a limited number of emotions with nonverbal behavior. Our lab has documented displays for several emotions, including embarrassment, love, desire, compassion, gratitude, and awe, to name just a few states that previously were thought not to possess a distinct display. I then present an argument for how individual differences in emotion, although fleeting, shape the social environment. This argument focuses on the functions of nonverbal display: to provide information to others, to evoke responses, and to serve as incentives of preceding or ensuing social behavior. This reasoning sets the stage for the study of the relationships between personality, psychopathology, and expressive behavior, to which I turn in the final part of the paper. Here I show that basic personality traits (e.g., extraversion, agreeableness) and psychological disorders (e.g., externalizing disorder in children, autism) have expressive signatures that shape social interactions and environments in profound ways that might perpetuate and transmit the trait or disorder.
