Models are representations. There are model airplanes, mathematical models, and models of buildings. In each case, the model is designed to provide a simplified view of some more complex object, phenomenon, or process, so that fundamental properties or characteristics can be high-lighted and examined. Models highlight some features that their designers believe are particularly critical, and there is less focus on other features. Thus, by examining models, one learns not only about the object, situation, or process, but also about the perspective of the designer.

In communication study, models function in this same way, allowing for the simplification of complex dynamics to help scholars and students better understand the components and processes that are involved. As with other models, communication models also provide important insights into the perspectives of the designers.

One of the first scholars to examine the...
