ABSTRACT

In the field ofmass communication, the term theory is often loosely defined.1 Paradigms,2

conceptual frameworks, models, normative theories and, of course, actual theories are all frequently referred to as theory, although very different constructs are represented by those words. As traditionally defined in science, a theory is a systematically related set of statements about the causes or relationships underlying observable phenomena (Rudner, 1966).Theories aredevelopedbyabstracting fromobservationandareconfirmedthrough repeated experiments designed to test hypotheses related to the theory. The result is often the development of law-like generalizations about underlying causes and relationships. The purpose of a theory is to increase scientific understanding through a systemized structure capable of both explaining and predicting phenomena (Christensen & Raynor, 2003; Hunt, 1991).
