Review of Basic Theories in Communication Studies
1. Agenda-Setting Theory
Proponents: Maxwell McCombs and Donald Shaw
Core Idea: Media influences the public’s ranking of issue importance by selecting and emphasizing certain topics.
Explanation: What the media reports, the public tends to focus on. For example, if the media constantly reports on climate change, people may perceive climate change as one of the most important current issues.
2. Spiral of Silence Theory
Proponents: Elisabeth Noelle-Neumann
Core Idea: People fear being isolated for expressing minority views, so they choose to remain silent, causing the mainstream views to become stronger.
Explanation: In a social setting, if someone supports an unpopular policy, they might choose not to express their opinion due to fear of being ridiculed or excluded.
3. Uses and Gratifications Theory
Proponents: Elihu Katz et al.
Core Idea: Audiences actively choose media to satisfy their needs, such as obtaining information, entertainment, or building social connections.
Explanation: For example, some watch the news to get current affairs information, while others scroll through short videos for relaxation and entertainment.
4. Two-Step Flow of Communication Theory
Proponents: Paul Lazarsfeld et al.
Core Idea: Information first influences Opinion Leaders, and then it is passed on to ordinary people through them.
Explanation: A celebrity (Opinion Leader) shares their view on a certain brand of mobile phone, and fans may consequently be more inclined to purchase that brand’s phone.
5. Media Dependency Theory
Proponents: Sandra Ball-Rokeach and Melvin DeFleur
Core Idea: The degree of dependency people have on the media determines the media’s influence on them.
Explanation: During a natural disaster, people rely more heavily on news media for information, significantly enhancing the media’s influence.
6. Cultivation Theory
Proponents: George Gerbner
Core Idea: Long-term exposure to a certain type of media content influences people’s worldview, leading to a distorted perception of the real world.
Explanation: If someone watches violent movies for a long time, they might perceive the real world as more violent than it actually is.
7. Framing Theory
Proponents: Erving Goffman et al.
Core Idea: The media shapes how audiences understand events through specific organizational and presentation methods.
Explanation: For example, the same protest event can be presented by the media using two different frames—“peaceful demonstration” or “violent conflict”—leading to vastly different audience interpretations.
8. Diffusion of Innovations Theory
Proponents: Everett Rogers
Core Idea: The diffusion of innovation occurs in different stages, influenced by early adopters, social networks, and cultural background.
Explanation: After a new smartwatch is launched, early adopters purchase and use it first, subsequently influencing their friends and family to join the purchasing line.
9. Media Ecology Theory
Proponents: Marshall McLuhan et al.
Core Idea: Media, as a technological form of information transmission, profoundly influences society, culture, and behavior.
Explanation: McLuhan’s “The medium is the message” suggests that different media forms themselves shape people’s communication methods and thought habits; for instance, the TV era emphasizes visual expression, while the book era emphasizes textual logic.
10. Cultural Hegemony Theory
Proponents: Antonio Gramsci
Core Idea: Through cultural transmission, the social elite can maintain control over ideology.
Explanation: Mainstream films and TV programs often consolidate existing social values through narrative, such as promoting individual striving and consumerism.
11. Knowledge Gap Theory
Proponents: Philip Tichenor et al.
Core Idea: Information disseminated by the media often exacerbates the information gap between high-knowledge and low-knowledge groups.
Explanation: For example, the dissemination of scientific news might allow educated people to understand related knowledge better, while those with lower education levels may become even more unfamiliar with these topics.
12. Third-Person Effect Theory
Proponents: W. Phillips Davison
Core Idea: People tend to believe that the influence of media content on others is greater than on themselves, and thus take certain actions in response.
Explanation: For example, some believe that advertisements strongly influence others’ purchasing decisions but have little impact on themselves, leading them to advocate for stricter regulation of advertising.
13. The Strength of Weak Ties Theory
Proponents: Mark Granovetter
Core Idea: In social networks, “weak ties” (acquaintanceship) are more effective than “strong ties” (close ties) in spreading information and facilitating resource flow.
Explanation: An ordinary friend might provide you with important job-seeking information because the information they encounter is different from your circle, whereas close friends usually share similar information with you.
14. Double Reality Theory
Proponents: Nikki K. R. Kroeber et al.
Core Idea: Media reports often construct the relationship between reality (the content presented by the media) and social reality (what people actually experience) simultaneously.
Explanation: For example, people perceive a high crime rate from media reports, yet they rarely encounter crime directly in their own daily lives.
15. Gap Model of Information Seeking
Proponents: Robert S. Taylor
Core Idea: Information seeking behavior originates from the “information gap” between a perceived problem and current knowledge.
Explanation: When someone learns that a company might go bankrupt but doesn’t know the specific reasons, they may actively search for relevant information to bridge this gap.
16. Media Richness Theory
Proponents: Richard L. Daft and Robert H. Lengel
Core Idea: Different media possess varying degrees of information richness, and complex information requires transmission through rich media.
Explanation: Face-to-face interaction is the richest medium, while written text is relatively poor; therefore, complex negotiations are better suited for face-to-face formats than email.
17. Social Comparison Theory
Proponents: Leon Festinger
Core Idea: People evaluate their own opinions and abilities by comparing themselves to others, and the media intensifies this comparison.
Explanation: On social media, after seeing others’ successful lives (such as vacation photos), people might feel that they are not as successful or happy.
18. Uses and Dependency Model
Proponents: Sandra Ball-Rokeach and Melvin DeFleur
Core Idea: The influence of the media depends on the individual’s degree of dependency on media information and the strength of the social system.
Explanation: During a large-scale internet outage, people’s dependency on social media may reveal critical vulnerabilities within the communication system.
19. Selective Exposure Theory
Proponents: Joseph Klapper
Core Idea: People tend to select media information that aligns with their existing views while avoiding contradictory information.
Explanation: A political preference might cause supporters of a certain party to more frequently watch news channels consistent with their party’s stance.
20. Fourth Estate Theory
Proponents: Edmund Burke
Core Idea: The media, as an independent social institution, plays the role of supervising and balancing power.
Explanation: Investigative journalism that exposes government corruption or corporate misconduct embodies the media’s role as the “Fourth Estate.”
21. Perceptual Filter Theory
Proponents: Harold Lasswell
Core Idea: During the process of information dissemination, people’s background, preferences, and experiences influence how they receive and understand information.
Explanation: The same piece of news might be interpreted as a positive signal by optimists, while pessimists might view it as a negative warning.
22. Information Overload Theory
Proponents: Alvin Toffler
Core Idea: When information exceeds human processing capacity, it can lead to decision difficulty, decreased efficiency, and even anxiety.
Explanation: When shopping on an e-commerce platform and faced with hundreds of similar products, people may find it harder to make a purchasing decision.
23. Media Logic Theory
Proponents: David Altheide and Robert Snow
Core Idea: The presentation style and logic of the media profoundly influence society’s ways of thinking and behavioral patterns.
Explanation: TV programs often use an entertainment logic, which causes news reporting to tend toward attracting viewers through entertainment rather than deep analysis.
