Interpersonal communication focuses on examining the interactions between individuals, which may take the form of dyadic relationships (e.g., romantic partners, or provider/patient) as well as individuals within a social network (e.g., work, church, family and supportive others). Faculty members in our department have examined how interpersonal communication can be influenced by (a) the medium, such as computer-mediated communication and social media, (b) the process, such as deception, conflict, and psychological factors influencing persuasion and argumentation processes, and (c) the dynamics of interpersonal coordination, such as identity construction, self-presentation, and social support. The social influence domain includes persuasion, compliance gaining, interpersonal influence, and societal change effects that may involve risk, crisis, political, and/or health campaigns within social and/or mass mediated contexts. Research typically investigates theory-driven approaches to various cognitive, affective, and motivational processes associated with how people think of, feel about, and respond to a range of influence experiences. Study within the department often focuses on the methods sources employ to manipulate targets in various contexts, as well as the means by which those targets resist, adapt to, and respond to such influence.
