CHAPTER 10
Media Theory and Effects
____________________________________________________________
LEARNING OBJECTIVES
After reading this chapter students should be able to understand the following concepts:
Media effects research: Understand key terms relevant to the study of media effects such as media,
effects, and theory and review the strengths and limitations of research methods used by media
researchers.
Communication process model: Identify the elements of simple communication process models.
Early research: Understand the history of effects research and its role in policy making research and
selection of research topics.
CHAPTER FOCUS
Media’s impact on society has long been controversial. Scholars have spent thousands of hours analyzing
media effects. Major policy decisions regarding media often rely on research to support goals and
assumptions and to predict probable outcomes.
The first section provides definitions of media, effects, and theory. The terms explained here provide an
introduction to media theory and research and will help students understand and talk about media effects
studies. Obviously you could spend weeks discussing the material presented in this chapter’s first section
alone. Five major types of research – sample surveys, content analysis, laboratory experiments, field
studies, and ethnographic studies – are explained, noting strengths and weaknesses for each.
The next section examines communication as process consisting of five different elements that define the
broad objectives of media research. It explains how communicators, content, channels, and audiences
influence the outcomes of communicating.
TERMS, CONCEPTS, AND EXERCISES
Conducting and evaluating Media Effects Research
Terms: audience, media, media content, media technology, technological convergence, correlation,
causation, effects size, statistical significance, random samples, sampling error, causal explanation,
sample surveys, content analysis, laboratory experiments, confounding variables, field studies,
ethnographic studies, participant observation
oTake time to explain the terms such as theory, correlation, causation, effects size, statistical
significance to lay the foundation for understanding the material presented in this chapter.
oThe problem of how to measure human attention, understanding, learning, and opinion formation
Communication as a Process – A simple Communication Model
Terms: communication as process, originators, contents, channels, audiences, effects, Harold Lasswell,
gatekeepers, media exposure, sender, transmitter, receiver, recipient, noise, feedback, message, encoding,
decoding
oWhat are the advantages of describing communication as a process? Describe the five elements
and how they guide media research. Go over the simple communication model in Exhibit 10.b.
Early Research on Media Effects
Terms: mass propaganda, bullet (hypodermic-injection) theory, intervening variables, opinion leaders,
two-step flow, selective exposure, selective perception
oStudents know little about media research. If students understand changes in media research, they
have context, for their own questions. Review the timeline on media effects research development
A Sampling of Media Effects Theories
Terms: cultivation theory, George Gerbner, Annenberg School for Communication University of
Pennsylvania, perception of reality, stereotypes, mainstreaming, socialization, social learning theory,
Albert Bandura, reciprocal determinism, behaviorism, spiral of silence, majority opinion, third person
effect, agenda-setting theory, Maxwell McCombs, Donald Shaw, gatekeepers, reciprocal relationship
oExplain how mainstreaming reinforces stereotypes (Stereotypes are shortcuts for the writer, a way
to communicate to the audience, that can be deliberately oversimplified versions of reality to fit
preconceived images). Discuss why stereotypes are so prevalent in television entertainment. Point
out the disadvantages of stereotypes: stereotypical images perpetuate existing opinions, which
may not always be positive, in the minds of the viewer.
oHow does television’s fictional world differ from the real world? Consider characters’ ages, sex,
ethnicity, lifestyle, location, etc. Which “world” has a greater interest for the television-viewing
public? Discuss crime on television. Who are likely to be the perpetrators of crime and who are
the likely victims? Discuss occupations of television’s heroes. How many TV characters are
plumbers, contractors, janitors, accountants, or assembly-line workers? Why?
oWhat is meant by “socialization”? Can TV teach prosocial values as well as antisocial values?
Get students to discuss social values they may have learned, at least in part, from television. You
The Active Audience Approach
Terms: uses and gratifications, gratifications sought, gratifications obtained, ritualistic, instrumental,
glow and flow principle, elaboration likelihood model, central route, peripheral route, motivation, ability,
congruence, selective exposure, brand marketing theory, brand loyalty, technological determinism,
Marshall McLuhan, multitasking
oHave students mention some of the needs they use media to satisfy: information, relaxation,
emotional release, or companionship. Explain the difference between gratifications sought and
The Effects of Media Violence: A Case Study
Terms: violence, justified violence, gratuitous violence, excessive violence, aggressive behavior,
government-sponsored censorship, industry self-regulation
oSummarize research findings on television violence. It is important to point out that while
exposure to television violence may be related to aggressive behavior, attitudes, and values
other variables such as age, personality traits and exposure to family violence may explain
aggressive behavior. Why are young children more vulnerable to the effects of media
violence? Have students debate the criticisms of media violence research. What is the
acceptable effects size to warrant action?
