The effect of extroversion on communication: Evidence from an interlocutor visibility manipulation
We compare peoples speech and gesture use when they can and cannot see their listener. We measure how extroverted-introverted speakers are. We find that people speak and more when they cannot see their listener. Extroversion affects how much speakers gesture but not how much they speak. These results suggest that extroversion affects how people interpret the nonverbal cues of their interlocutor.
