Item Flows of information/influence and diversity of content within online public fora in the context of civil society(2012-12) Choi, Sujin; Strover, Sharon; Straubhaar, Joseph; Chen, Wenhong; Brundidge, Jennifer; Stroud, Natalie J.Online public fora based on social media facilitate social interaction and synchronous online discussion. Social-media-based public fora resemble real-life political talks, and induce a larger number of and a wider variety of participants than blogs or Usenet newsgroups. By investigating two online groups centered on political discussions on Twitter, this study explores how information and influence flow, how diverse the actual discourse is, and to what extent the online groups communicate with the government. Using network analysis and content analysis/co-word analysis, this study has the findings as follows: In terms of the structural qualities, online public fora are relatively inclusive, but are centralized on a few participants and do not have a statistically significant indication of being equitable in discussion. The two-step flow of communication operates along with the presence of opinion leaders who turn out to be influentials but not content creators. Interestingly, the flow of influence is likely to be less centralized than the flow of information, which implies the importance of the reliability of a given message rather than that of the author. In terms of the actual discourse, participants turn to like-minded fellow citizens’ remarks. Discourses are more emotional than cognitive and exhibits more anger than anxiety. Influential discourses are those with negative emotion more so than with positive emotion and those that are cognitive rather than emotional. Among cognitive components, assertive and strong discourses have greater social influence than analytical discourses. In terms of the interaction with the e-government outlet, the distance between public authorities and private citizens is continuously present despite the decline of temporal and physical distance via the Internet. Based on the results, this study suggests a reconsideration of the Habermasian public sphere in online public fora. It contributes to the literature by empirically confirming the presence of the two-step flow of communication in online public fora and testing the difference between the flow of information and the flow of influence. In addition, it broadens the realm of research on political communication by exploring not only sources/ideological perspectives but also emotional/cognitive aspects in discussions. Methodologically, structure/context, multi-level, and quantitative/qualitative analyses allow this study to have a comprehensive account of online public fora. Practically, this study proposes to improve the interactivity with citizens as the next stage of e-government development.Item The impact of selective exposure on political polarization and participation : an exploration of mediating and moderating mechanisms(2013-05) Kim, Yonghwan; Gil de Zúñiga, Homero; McCombs, Maxwell E.; Stroud, Natalie JominiThis dissertation seeks to improve our understanding of the process by which citizens' selective exposure contributes to attitudinal polarization and engagement in political activities. In this dissertation, I test two models that explicate the relationship between selective exposure and political polarization and participation. The knowledge model suggests that the effects of selective exposure on individuals' attitudinal polarization and political engagement are mediated by knowledge of candidate issue stances. The stereotype model proposes that selective exposure indirectly influences polarized attitudes and political participation via stereotypical perceptions of candidates (i.e., McCain's age and the prospect of a Black presidency). By posing issue knowledge and stereotypical perceptions as potential mediators, this study extends current literature to analyze why and how selective exposure leads to polarization and political participation. The results provide evidence that selective exposure influences individuals' stereotypical perceptions of the candidates' age and race, and these stereotypic perceptions influence attitudinal polarization and participation in campaign activities. There was no support for the knowledge model; selective exposure did not have a significant relationship with citizens' issue knowledge nor did it play a mediating role in the relationship between selective exposure and political polarization and participation. This dissertation thus challenges the argument that selective exposure is normatively desirable due to its contribution to citizens' greater levels of political participation. The findings of this study call into question such a contention because the results show that individuals who engage in selective exposure are motivated to participate in political activities by forming stereotypic perceptions of candidates rather than by gaining factual issue knowledge, which is in contrast to democratic theories' assumptions of informed citizenship. Turning to the role of exposure to dissonant media outlets, two contrasting roles were found. On one hand, results offer some evidence that dissonant media use contributes to gaining issue knowledge and inspiring citizen participation. On the other hand, some findings suggest that it reinforces, rather than attenuates, citizens' attitudinal polarization and stereotypical perceptions of candidates. Thus the findings from this study offer mixed support for encouraging citizen exposure to dissimilar viewpoints.Item The role of emotion in selective exposure, information processing, and attitudinal polarization(2010-05) Kim, Soohee, 1980-; Stroud, Natalie Jomini; Jarvis, Sharon E.This thesis reviews the role of emotions in one’s choice of information, information processing, and political attitudes. Theoretical and empirical endeavors to date have focused primarily on how emotions influence attitudes and information processing, leaving the actual processes guiding these outcomes in the margins. Specifically, it has been largely unexplored how emotions influence individuals’ information search behavior and then attitudes and information processing. Noting that the purposeful selection of likeminded information, often referred to as selective exposure, is commonly enacted when an individual first initiates information processing, and is also likely influenced by emotions, this study explores how emotions may affect people’s tendency to seek out congruent information. In addition, this study examines how the relationship between emotions and selective exposure in turn may affect aspects of information processing and attitudes. By designing an online experiment, I first tested how certain negative emotions (anger/fear) affected one’s pursuit of certain types of information (consistent/inconsistent) and second, I investigated how these emotions and information selections influenced subsequent information processing and attitudes. Results showed that while anger motivated more likeminded exposure for Republicans than fear, fear promoted more likeminded exposure for Democrats than anger. Further, anger prompted people to process messages more closely and to develop more polarized attitudes compared to fear. In addition, pro-attitudinal exposure produced more message-relevant thoughts for Republicans than counter-attitudinal message exposure, while it was counter-attitudinal exposure that yielded more message-relevant thoughts for Democrats. No such effect, however, was shown for attitudinal polarization.Item Strong-tie diversity and weak-tie diversity : the paradoxical roles of Internet use and political tolerance in supporting political diversity and participation(2011-12) Jun, Najin; Brundidge, Jennifer; Strover, Sharon; Wilkins, Karin G.; Straubhaar, Joseph; Gil de Zuniga, HomeroThe purpose of this study is: 1) to explore the ways in which the Internet may affect individuals’ political diversity in different strengths of social relationships; 2) to identify which of strong-tie diversity and weak-tie diversity contributes more to political tolerance; and 3) to investigate the extent to which tolerant people are different from the less tolerant in their participation decisions when exposed to political diversity. In order to examine the contribution of Internet news use to political heterogeneity, the current study examines the moderation of the negative influence of politically selective exposure on the Internet on political diversity in social networks by Internet news use. To identify the better contributor to tolerance, the two diversities are compared. To assess the consequence of exposure to political difference for political participation for tolerant and less tolerant people, the present study examines any moderating effect of tolerance between political network heterogeneity and participation. It also observes the moderating effect in different tie strengths. This study utilizes data obtained from the U.S. Citizenship, Involvement, Democracy (CID) survey conducted by a collaboration of Center for Democracy and Civil Society at Georgetown University and the European Social Survey. The sample is 1,001 adults aged 18 and over and representative of the contiguous United States. The dataset contains items concerning Internet use, informal social networks, the composition and diversity of ties and associations, democratic values and tolerance under the primary themes of democracy, social capital and civic engagement. The data are analyzed by hierarchical and OLS regression. According to the findings, Internet news use contributes to individuals’ overall political diversity by reducing the negative influence of the selective exposure occurring from online interaction with homogeneous people. When examined in different strengths of interpersonal relationships, selective exposure discourages strong-tie diversity while encouraging weak-tie diversity. Internet news use positively affects strong-tie diversity but had no influence on weak-tie diversity. Weak-tie diversity is found to be a better contributor to political tolerance. Politically tolerant individuals tend to be discouraged for political participation when exposed to difference in their social relationships. Therefore, while political tolerance may increase overall political diversity, it may as well threaten the balance between deliberation and participation. Closer interpersonal associations are not found to reduce the demobilizing effect of exposure to difference for tolerant individuals.
