Theories of Communication
The study of communication and mass media has led to the formulation of many theories: structural and functional theories believe that social structures are real and function in ways that can be observed objectively; cognitive and behavioral theories tend to focus on psychology of individuals; interactionist theories view social life as a process of interaction; interpretive theories uncover the ways people actually understand their own experience; and critical theories are concerned with the conflict of interests in society and the way communication perpetuates domination of one group over another .
The earliest theories were those propounded by Western theorists Siebert, Paterson and Schramm in their book Four Theories Of the Press (1956). These were termed "normative theories" by McQuail in the sense that they "mainly express ideas of how the media ought to or can be expected to operate under a prevailing set of conditions and values." Each of the four original or classical theories is based on a particular political theory or economic scenario.
I) CLASSICAL THEORIES
Authoritarian Theory
According to this theory, mass media, though not under the direct control of the State, had to follow its bidding. Under an Authoritarian approach in Western Europe, freedom of thought was jealously guarded by a few people (ruling classes), who were concerned with the emergence of a new middle class and were worried about the effects of printed matter on their thought process. Steps were taken to control the freedom of expression. The result was advocacy of complete dictatorship. The theory promoted zealous obedience to a hierarchical superior and reliance on threat and punishment to those who did not follow the censorship rules or did not respect authority. Censorship of the press was justified on the ground that the State always took precedence over the individual's right to freedom
