Locating Physiology in the Study of Interpersonal Communication

Interpersonal communication is a biological behavior that necessitates coordination between multiple physical and physiological systems. Concurrent with the demands placed on the body to communicate, verbal and nonverbal messages impact the body. The goal of this chapter is to introduce the physiological approach toward the study of interpersonal communication. In the chapter, we start by reviewing the theory of evolution by natural selection as a theoretical foundation explaining the relationship between the physical body and interpersonal communication. We then review research highlighting physiological systems implicated in biophysiological behavioral research. Finally, we provide a preview of the chapters included in this edited collection.
