Communication studies identifies bodies as both objects of communication and producers (or sites) of communication. Communication about bodies—for example, gendered bodies, disabled bodies, obese bodies, and surgically modified bodies—influences bodies at the physical, material level by determining how they are treated in social interactions, in medical settings, and in public institutions. Communication about bodies also forges cultural consensus about what types of bodies fit in particular roles and settings. In addition to analyzing the stakes of communication about bodies, communication studies identifies bodies as communicating forces that cannot be accounted for by standards of reason, meaning, and decorum. Bodies are physical, material, affective beings that communicate because of, not in spite of, their messy, ineffable status. Moreover, communication is an embodied process that involves a range of material supports, including human bodies, technological bodies, and other nonhuman physical and biological bodies. Investigating bodies as communicating forces compels an understanding of communication that is not exclusively rational, meaning-oriented, and nonviolent.
