Mass communication research THEORIES

A THEORY is a statement that describes, explains, or predicts how one things causes another thing. Scientists often express this as describing how one or more independent variables affects or causes a dependent variable.

One silly example is that Television viewing sucks your brain waves and makes you stupid.
In this case, the cause or INDEPENDENT VARIABLE is: Television viewing [hours]
And the effect or DEPENDENT VARIABLE is: Stupidity [intelligence].

The scientific approach holds that THEORIES should be tested to see if they are correct.
The traditional scientific method involves:

  1. forming a HYPOTHESIS,
  2. carrying out an appropriate testing procedure, and
  3. interpreting the results to see if they are consistent with the hypothesis.
What does a theory do for you? How do you know if you have a "good" theory?

There are 5 REQUIREMENTS OF A GOOD THEORY

  1. It EXPLAINS current observations
  2. It PREDICTS future events
  3. It is TESTABLE [theory can be falsified]
  4. It is SIMPLE. Or at least simpler than other explanations
  5. It is USEFUL [has practical applications].
Historically, many of the original theories of mass communication were drawn from psychology. Here are some of the most famous mass communication theories:
