Understanding Today’s Theory and Research
Media Effects: Social Science Perspectives
Theories of the social science perspective have developed from research featuring controlled laboratory experiments and content analyses.
Understanding Today’s Theory and Research
Diffusion of innovations theory five types of people have different levels of willingness to accept new ideas from the media:1. Innovators tend to be politically liberal
extroverts who are venturesome and eager to try new ideas.
2. Early adopters make quick but informed choices.
3. Early majority makes careful, deliberate decisions.
4. Late majority tends to be skeptical.5. Laggards tend to be conservative,
traditional and resistant to any type of change.
Understanding Today’s Theory and Research
• Cultural Studies• The role that media play in changing
entire societies is difficult to measure.•media ecology•Gender studies•Political-economic analysis
Controversies in Media Impact
• Research vs. “Common Sense”• Limitations of research confuse
conventional wisdom.Causation and correlation
•Correlation only proves that two things occurred at the same time, not that one thing caused the other.
