Recent calls for censorship of rap music have demonstrated the need to test the perceptual and especially the behavioral components of Davison's third-person effect hypothesis. The hypothesis states that people perceive media content to have a greater impact on others than on themselves (perceptual component), and that these perceptions lead people to take actions, such as censorship, to prevent the impact (behavioral component). Results of a survey of college students (N = 202) using rap lyrics as the context revealed strong support for both components of the hypothesis. Limited support was found for the social distance corollary of the perceptual component, while the knowledge corollary of the perceptual component was not supported. A new target corollary to the perceptual component was proposed; it predicts that those groups seen as likely targets of a communication will produce larger third-person perceptions than will generalized others.

Political communication researchers have devoted a great deal of attention to the role of political advertising, the Internet, and political discussion in civic and political life. In this article, we integrate and extend this research by developing a campaign communication mediation model of civic and campaign participation. Two data sets are merged for this inquiry: (a) content-coded ad-buy data on the placement of campaign messages on a market-by-market and program-by-program basis and (b) a national panel study concerning patterns of traditional and digital media consumption and levels of civic and campaign participation. Exposure to televised campaign advertising is estimated by developing an algorithm based on the market and program placement of specific ads and geocoded survey respondents' viewing of certain categories of television content in which these ads were concentrated. Structural equation models reveal that advertising exposure drives online news use in ways that complement conventional news influences on political discussion and political messaging. However, campaign exposure emphasizing ''attack'' messages appears to diminish information seeking motivations via broadcast and print media, yet only indirectly and weakly suppresses participation in civic and political life. Further, alternative specifications reveal that our original model produces the best fit, empirically and theoretically. We use these insights to propose an O-S-R-O-R (orientations-stimuli-reasoning-orientations-responses) framework as an alternative to the longstanding O-S-O-R model in communication and social psychology.

Recent communication research concerning participatory politics has found that the effects of media, especially campaign ads, conventional news, and online political resources, are largely mediated through interpersonal discussion about politics. This article extends this line of theorizing about the role of political conversation in citizen competence by testing an O-S-R-O-R model of campaign communication mediation, a modification and extension of the longstanding O-S-O-R model of communication effects. This model combines insights from iterations of the communication mediation model (McLeod et al., 2001; Shah et al., 2007) and cognitive mediation model (Eveland, 2001;Eveland, Shah, & Kwak, 2003) to theorize a set of the interrelated reasoning (R) processes that channel the influences of campaign exposure and news consumption on political engagement. Three key mediators of campaign and news influence are postulated: face-to-face political conversation, online political messaging, and cognitive reflection. We provide empirical evidence to test this model by merging two datasets: (1) tracking of the content and placement of campaign messages in the

We investigated framing effects of television news coverage of an anarchist protest. Three treatment stories differed in their level of status quo support. Status quo support had significant effects on viewers, leading them to be more critical of, and less likely to identify with, the protesters; less critical of the police; and less likely to support the protesters' expressive rights. Status quo support also produced lower estimates of the protest's effectiveness, public support, and perceptions of newsworthiness. The results substantiate concerns about status quo support by showing that it can influence audience perceptions.

This study used an experiment embedded within a Web-based survey to examine the influence of contextual (i.e., face-to-face vs. online chat room discussion) and socialpsychological factors on individuals' willingness to express opinions. In this experiment, respondents were asked whether they would be willing to express an opinion if they were placed in a face-to-face discussion group in one condition and in an online chat room discussion group in the other condition. Results indicate that print news use, fear of isolation, communication apprehension, future opinion congruency, and communication setting significantly predict willingness to speak out. In addition, not only did fear of isolation have a negative main effect on opinion expression, but this effect was significantly attenuated by computer-mediated discussion. Findings suggest that computer-mediated communication may avoid some of the dysfunctional social-psychological influences found in face-to-face interactions and create a forum conducive for public deliberation.
