This chapter reveals the many ways that nonverbal cues allow for engagement with others and the ways in which people’s behaviors in those interactions coordinate with one another to allow people to communicate with others. The chapter discusses the ways in which nonverbal cues create the circumstances for interaction, details their role in conversational turn-taking, reviews some specific forms of coordinated interaction, and provides discussion of the ways in which people’s nonverbal cues work alongside their verbal behavior to craft coherent and purposeful messages. Specific concepts include propinquity, privacy, adaptation, synchrony, and mimicry. It then reviews relevant theories on how and why coordination works as it does.
