This article reviews a portion of the research on nonverbal behavior from a functional perspective. Specifically, the focus of this review is the role of nonverbal involvement (e.g., distance, gaze, touch; lean, orientation, paralinguistic cues, facial expression) in the interactive function of social control. The social control function describes a general goal of exercising influence to change the behavior of others. Specifically, that process is designed to produce reactions not likely in the absence of such influence. Patterns of nonverbal involvement in the service of the social control function are reviewed in the areas of (a) status, power, and dominance; (b) persuasion; (c) feedback/reinforcement; (d) deception; and (e) impression management. In contrast to the common assumption that nonverbal behavior usually reflects a spontaneous and consistent affective reaction, this research strongly suggests that in many instances nonverbal behavior may be managed to influence the behavior of others.
