This chapter centers on three related functions served by nonverbal cues: showing our identities (identity displays), managing our images to others (image/impression management or self-presentation), and discerning impressions of who others are (impression formation). The chapter discusses the complexities of each of these processes and provides myriad examples of how nonverbal cues play a role in these fundamental human activities. The chapter also overviews theories related to impression management and impression formation and reveals some of the ways that these processes, and the role of nonverbal communication within them, are implicated in many of the issues that face societies.
