Communication theory
Communication theory is a proposed description of communication phenomena, the relationships among them, a storyline describing these relationships, and an argument for these three elements. Communication theory provides a way of talking about and analyzing key events, processes, and commitments that together form communication. Theory can be seen as a way to map the world and make it navigable; communication theory gives us tools to answer empirical, conceptual, or practical communication questions.[1]

Communication is defined in both commonsense and specialized ways. Communication theory emphasizes its symbolic and social process aspects as seen from two perspectives—as exchange of information (the transmission perspective), and as work done to connect and thus enable that exchange (the ritual perspective).[2]
Sociolinguistic research in the 1950s and 1960s demonstrated that the level to which people change their formality of their language depends on the social context that they are in. This had been explained in terms of social norms that dictated language use. The way that we use language differs from person to person.[3]
Communication theories have emerged from multiple historical points of origin, including classical traditions of oratory and rhetoric, Enlightenment-era conceptions of society and the mind, and post-World War II efforts to understand propaganda and relationships between media and society.[4][5][6] Prominent historical and modern foundational communication theorists include Kurt Lewin, Harold Lasswell, Paul Lazarsfeld, Carl Hovland, James Carey, Elihu Katz, Kenneth Burke, John Dewey, Jurgen Habermas, Marshall McLuhan, Theodor Adorno, Antonio Gramsci, Jean-Luc Nancy, Robert E. Park, George Herbert Mead, Joseph Walther, Claude Shannon and Stuart Hall—although some of these theorists may not explicitly associate themselves with communication as a discipline or field of study.[4][6][7][8]
One key activity in communication theory is the development of models and concepts used to describe communication. In the Linear Model, communication works in one direction: a sender encodes some message and sends it through a channel for a receiver to decode. In comparison, the Interactional Model of communication is bidirectional. People send and receive messages in a cooperative fashion as they continuously encode and decode information. The Transactional Model assumes that information is sent and received simultaneously through a noisy channel, and further considers a frame of reference or experience each person brings to the interaction.[9]
Some of the basic elements of communication studied in communication theory are:[10]
Axiology[edit]
Axiology is concerned with how values inform research and theory development.[42] Most communication theory is guided by one of three axiological approaches.[43] The first approach recognizes that values will influence theorists' interests but suggests that those values must be set aside once actual research begins. Outside replication of research findings is particularly important in this approach to prevent individual researchers' values from contaminating their findings and interpretations.[44] The second approach rejects the idea that values can be eliminated from any stage of theory development. Within this approach, theorists do not try to divorce their values from inquiry. Instead, they remain mindful of their values so that they understand how those values contextualize, influence or skew their findings.[45] The third approach not only rejects the idea that values can be separated from research and theory, but rejects the idea that they should be separated. This approach is often adopted by critical theorists who believe that the role of communication theory is to identify oppression and produce social change. In this axiological approach, theorists embrace their values and work to reproduce those values in their research and theory development.[46]
