Extroverts are more attuned to social rewards, so they are more likely to flash a smile for effect. A notable exception are introverts - like me - whom I call "socially accessible" introverts. We have been trained well to smile and nod, which can place a burden on our processing efforts.

Laurie HelgoeIntrovert conversations are like jazz, where each player gets to solo for a nice stretch before the other player comes in and does his solo. And like jazz, once we get going, we can play all night. Extrovert conversations are more like tennis matches, where thoughts are batted back and forth, and players need to be ready to respond. Introverts get winded pretty quickly.
