Powerpoint V: Social influence in Politics Flashcards
What are two sources of influence that political media research focuses on?
- News (TV broadcasts, political forums)
- Political Advertising
What are 3 models for media effects?
- Direct Effects Model
- Limited Effects Model
- Powerful Effects Underlying Limiting Conditions Perspective
What perspective does the direct effects model take?
Hypodermic Perspective
–> perspective that the media has a pervasive, direct, and powerful influence
What is the main suggestion of the direct effects model?
Early on, anecdotal evidence suggested that powerful media exerted very direct and powerful effects on citizens’ political attitudes, beliefs, and behaviours
What perspective does the limited effects model take?
the perspective that the media does not change people’s attitudes
What is the main suggestion of the limited effects model?
Research survey data suggested that the media has little impact but instead simply reinforces existing values and attitudes
The idea that political attitudes become polarized, but dont really change
What is the main idea of the powerful effects under limiting conditions perspective?
The idea that the media can have a powerful effect (change opinions) but only under certain conditions and often indirectly
What are the 4 news effects?
- Agenda Setting
- Issue Priming of Presidential Evaluations
- Issue Framing
- Persuasion
Agenda Setting Effect
The empirical finding that extensive news coverage of an issue enhances the extent to which that issue is seen as an important national issue
Does news coverage change people’s attitude about a political issue?
No, but it changes the extent to which they see the issue as important
Describe participants, task, and conditions of the Iyengar & Kinder (1987) Agenda Setting experiments
- Recruited everyday citizens or university students to attend a multi-session lab study
- Participants watched edited 30-minute news broadcasts each day over the course of a week
- Participants were randomly assigned to watch news broadcasts that were edited either: (a) to not include a story on the target issue or (b) to always include a story on the target issue
- Participants rated the national importance of different issues at the start of the study and at the end of the study
Results of the Iyengar & Kinder (1987) Agenda Setting experiments
- Analyses suggested that greater news exposure to the target issue increased importance ratings by an average of 8.4
Why is inflation the only issue that did not significantly increase in importance after greater news exposure to the issue?
Ceiling effect - no room to boost it up. Inflation was a big enough issue at the time.
According to the Iyengar & Kinder (1987) Agenda Setting experiments, when participants were given open-ended questions asking them to this the most important national problems, what did they do?
Average percentage listing the target problem as an important national issue was 57.0%, which is 19.7% more than the people in the no exposure condition.
Do Iyengar & Kinder’s findings about agenda setting effects hold true for single session exposure to multiple stories?
yes
Do Iyengar & Kinder’s findings about agenda setting effects hold true after one week?
Yes
Do Iyengar & Kinder’s findings about agenda setting effects hold true in naturalistic contexts?
Yes
Who is most susceptible to agenda setting effects?
- People with low education (especially if they identify with a political party)
- People with low interest and involvement in politicsc
2 potential explanations for agenda setting
- Issues Accessibility
- Relevance
How does issues accessibility explain for agenda setting?
The ease of retrieval determines importance
–> if you have to work hard to remember something, you may think it might not be that important
presumes people non-thoughtful
How does relevance explain for agenda setting?
accessibility alone is not sufficient to create agenda setting
People must evaluate if issue is relevant as a problem: using emotions and perceptions of importance to others
Miller (2007) Experiment (to explain for agenda setting effects) - stories on crime
- Series of experiments in which participants received (a) no news stories on crime, (b) a news story on rising crime, or (c) a news story on falling crime
Participants listed most important problems facing the country
Participants rated emotions felt while reading stories & perception of issue importance to other (politicians & reporters)
Finding:
- Exposure to either story produced increased listing of crime
- Rising crime story produced bigger increases than falling crime story
Do Miller’s (2007) results from his agenda setting experiments fit with the accessibility?
Exposure producing increased listing fits with the accessibility explanation
Rising crime story producing bigger increases than falling crime story fits with the relevance explanation but NOT the accessibility explanation
What is a second reason for the rising crime story producing bigger increases than falling crime story in Miller’s (2007) experiment?
Rising crime story mediated by negative emotions and (more weakly) by perceptions of importance to politicians –> RELEVANCE
Issue priming of presidential evaluations
Empirical finding that increased coverage of an issue enhances the extent to which performance on the issue is used as a basis for overall evaluations of a president
Does news coverage of an issue change peoples’ assessments of how a president is performing on that issue?
No
How does news coverage of an issue affect presidential evaluations?
News coverage of an issue can change the extent to which people use that issue as a basis for their overall evaluations of the president
Iyengar & Kinder (1987) issue priming of presidential evaluations experiments - explain the process, conditions, and results
Recruited everyday citizens or university students to attend a multisession lab study
Participants watched edited 30-minute news broadcasts each day over the course of a week
Participants were randomly assigned to watch news broadcasts that were edited to either (a) not include a story on the target issues or to (b) always include a story on the target issue
Had participants rate presidential performance on various issues and overall performance
Results:
- news exposure to target issues increased the extent to which performance on those issues was a basis for overall performance assessments
–> all except unemployment were significant (reasons unknown - maybe the issue was already super relevant at the time)
How does the impact of single session exposure to multiple stories compare to the effects found in Iyengar & Kinder (1987) issue priming of presidential evaluations experiments?
Effects are similar
Some studies have examined the effects of priming on perceptions of presidential competence and integrity. What do the results suggest?
The results suggest that issue priming weakly enhances the impact of issue performance on perceptions of confidence. Issue priming has an even weaker effect on integrity
How do priming effects alter presidential popularity?
Priming effects shift the extent to which different issues determine how a president is evaluated?
How do positive performance issues affect presidential popularity?
President be becomes more popular
How do negative performance issues affect popularity?
President becomes less popular
Krosnick et al. examined priming in naturalistic contexts and coded content of news broadcasts for mentioning which two major crises?
- Iran-contra Affair for Reagan
- First Gulf War for Bush
What were the main findings of Krosnick et al.’s examination of news broadcasts covering the Iran-Contra Affair?
- Increased coverage of Iran-Contra enhanced the impact of Reagan’s Central American policy performance on overall evaluations of presidential performance
–> lower presidential approval ratings
What were the main findings of Krosnick et al.’s examination of news broadcasts covering the first gulf war?
Increased coverage of the gulf crisis enhanced the impact of Bush’s performance on the gulf war on overall performance ratings
–> resulting in higher approval ratings
Why did Bush’s popularity decline in the election against Clinton?
Economy was the issue of focus, not military & national security
According to Miller & Korsnick, who is most susceptible to priming effects?
People with:
- High political knowledge
- Trust in media
Note: it is highest for people who have both high political knowledge and trust in media!
Why does being high in political knowledge make someone more susceptible to priming effects?
Because being high in political knowledge facilitates understanding, storage, and retrieval of information from news
Why does trust in media make someone more susceptible to priming effects?
Because trust in media will facilitate acceptance of information
Miller and Krosnick (2000) Issue priming experiment 1: understanding the factors that make people susceptible to issue priming of presidential evaluations. What were the results?
Exposure to stories on (a) illegal drugs, (b) immigration, or (c) control
Measured presidential performance on issues in general, political knowledge, and trust in media
Findings:
- Exposure to news stories increased perceived national importance of issue and increased reliance on that issue in presidential evaluations ONLY for participants high in knowledge AND media trust
- Perceived national importance mediated the effect of exposure on issue priming in this group
Miller and Krosnick (2000) Issue priming experiment 2: understanding the factors that make people susceptible to issue priming of presidential evaluations. What were the results?
Exposure to stories on (a) crime, (b) pollution, (c) unemployment, or (d) control
Measured presidential performance on issues in general, political knowledge, and trust in media
Findings
- Priming effect ONLY for participants high in knowledge AND media trust showed priming effect
- no evidence that accessibility of issues mediated this effect
Issue Framing Effect
Empirical finding that episodic versus thematic news stories can alter viewers’ beliefs regarding responsibility for problems facing the country
Episodic framing
Case study or event-oriented report that depicts public issues in terms of concrete instances
Thematic framing
Report that places the issue in a more general or abstract context thereby focusing more on general outcomes and conditions
Which type of framing is most common? (and for what types of issues)
Episodic framing –> for issues such as crime & terrorism
