The spiral of silence (SoS) framework elaborates the factors that determine whether individuals are willing to express their opinions in public. Although previous scholarship has examined differences in between face-to-face and computer-mediated communication, research studies have rarely tested how perceived affordances of the channel influence whether individuals express opinions or self-censor. In this study (N = 399), we examine several propositions of SoS within the context of discussing police discrimination on Facebook. To extend the theory’s relevance to social networking sites, we examined how users’ perceptions of network association, social presence, anonymity, and persistence related to opinion expression. Findings indicate support for some of the theory’s original tenets, as well as the role of multiple perceived affordances in determining whether people will express an opinion to their online social network. We discuss the implications for measuring and understanding political expression and silencing on social media as well as offline. 相似文献

The use of second screens to dual-view television and social media is exponentially increasing. As a result, television producers are increasingly augmenting television content with social media comments from viewers, which may serve as a type of real-time public opinion indicator. The current research effort utilizes two experimental studies to explore the effects of this new media production practice on viewer's attitudes and opinions. In these studies, a Twitter feed was integrated in to entertainment (Study 1) and political (Study 2) television broadcasts and manipulated to convey either positive or negative opinions of the content. Participants' opinions were found to conform to the majority opinion presented in the manipulated Twitter feed in nearly all of the analyses. Implications for dual viewing and second screen use are discussed in light of findings. 相似文献

Noelle-Neumann's work on the spiral of silence (1974, 1977,1984) has been one of the most significant theoretical developmentsin public opinion research of the past quarter-century. Thetheory is well known among public opinion researchers, and anumber of research efforts have been directed toward examiningspecific parts of the theory. However, the theory is difficultto test, incorporating psychological, social-psychological andsociological variables, including psychological variables andsweeping changes in the social climate of opinion (cf. Noelle-Neumann1984). This study investigated the role of opinion thresholds, socialgroups and weighing of others' opinions in opinion expression.Using Krassa's (1988) computer simulation and modificationsof Noelle-Neumann's (1974) spiral of silence as a base, we testseveral theoretical modifications to the spiral of silence modelusing data gathered from people living in or near six nationalparks in Canada. Primary interest is on the ability of opinionthresholds, social group and weighing of others' opinions topredict the expression of opinion for particular issues. 相似文献

This study explored the potential of using sentiment analysis of tweets to predict referendum choices (Brexit). The feasibility of using StreamKM++ in the massive online analysis framework was examined over five categories, ranging from strongly agree to strongly disagree (to exit). A Naïve Bayes classifier was used to classify people’s opinions according to these categories. The prediction model resulted in high accuracy (97.98%), making it possible to use it in predicting opinions about public events and issues. The findings from this study may help practitioners, and policymakers understand the importance of sentiment analysis of social media in assessing public opinion and, accordingly, making certain voting predictions. 相似文献

This online survey conducted at a public university in the Northwest (N = 434) examines the influence of political involvement, information source attention, and online political discussion on young adults’ political efficacy. A factor analysis indicated that political information sources loaded into three factors including conventional and online hard news media such as newspapers, opinion and social media such as blogs or social networking websites, and public affairs websites including government and candidate websites. A path analysis revealed significant differences in their association with online political expression and external efficacy. As an entry point in the theoretical model, involvement in public affairs positively associated with attention to political information sources, online political expression, and external political efficacy. Attention to hard news and to public affairs websites positively predicted political efficacy. Attention to online opinion and social media and to public affairs websites positively predicted online political expression. 相似文献

Using the issue of genetically modified foods, this study examines how the Internet may affect the spiral of silence phenomenon in South Korea. More specifically, we explore whether the Internet has created a social environment, where people can exchange opinions more freely without being fearful of social isolation. Analyzing data from an online survey, we first examine whether the Internet can play a role as a source of information, from which people assess the climates of public opinion. Also examined is whether the opinions of netizens can comprise another form of opinion climate, exerting pressure on one's willingness to speak out. Finally, we explore whether expressing an opinion on the Internet is subject to the pressure of opinion climates. Findings suggest that the Internet may play an important role in shaping people's perceptions of opinion climates. Perceived opinion congruence with other people were significantly associated with one's willingness to participate in an online forum, indicating that expressing an opinion on the Internet may be subject to the spiral of silence effect. We conclude that the Internet in South Korea may not have helped to diminish the social pressure that keeps citizens from expressing a minority view. 相似文献

This study examines the issue of who tends to speak out against the tide of opinions on an online discussion forum and which forum conditions facilitate an individual’s public expression of honest opinions. In response to the call for experimental research, this study employed simulated online forums to place participants in multifaceted hostile online discussion situations. The findings indicate that an individual’s race, issue involvement, issue knowledge, fear of isolation, and the revelation of identity influenced opinion expression online. In particular, fear of isolation, which has been pointed out as the main reason for silencing minority opinion holders, played an unexpected role as a motivator for frank expression of opinions online. 相似文献

ABSTRACTHigh-choice media environments allow people to cocoon themselves with like-minded messages (confirmation bias), which could shape both individual attitudes and perceived prevalence of opinions. This study builds on motivated cognition and spiral of silence theory to disentangle how browsing political messages (both selective exposure as viewing full articles and incidental exposure as encountering leads only) shapes perceived public opinion and subsequently attitudes. Participants (N?=?115) browsed online articles on controversial topics; related attitudes and public opinion perceptions were captured before and after. Multi-level modeling demonstrated a confirmation bias. Both selective and incidental exposure affected attitudes per message stance, with stronger impacts for selective exposure. Opinion climate perceptions mediated selective exposure impacts on attitudes. 相似文献

The success of government social media relies on citizens' continual usage. Through the theoretical lens of the Uses & Gratifications theory, we develop a research model for mobile government microblogging services (GMS) continuance intention, in which citizens' perceived integration of online and offline social lives and internet censorship are incorporated. Based on data from 629 mobile GMS users in China, the results of the structural equation modeling analysis show that perceived online–offline integration has a significant and positive effect on the three dimensions of gratification: content gratification, social gratification, and process gratification, which jointly influence mobile GMS continuance. Citizens' perceived internet censorship negatively affects their mobile GMS continuance. These results might provide understanding about the unique aspects of government social media, especially in the context of internet censorship. 相似文献

Research articles are being shared in increasing numbers on multiple online platforms. Although the scholarly impact of these articles has been widely studied, the online interest determined by how long the research articles are shared online remains unclear. Being cognizant of how long a research article is mentioned online could be valuable information to the researchers. In this paper, we analyzed multiple social media platforms on which users share and/or discuss scholarly articles. We built three clusters for papers, based on the number of yearly online mentions having publication dates ranging from the year 1920 to 2016. Using the online social media metrics for each of these three clusters, we built machine learning models to predict the long-term online interest in research articles. We addressed the prediction task with two different approaches: regression and classification. For the regression approach, the Multi-Layer Perceptron model performed best, and for the classification approach, the tree-based models performed better than other models. We found that old articles are most evident in the contexts of economics and industry (i.e., patents). In contrast, recently published articles are most evident in research platforms (i.e., Mendeley) followed by social media platforms (i.e., Twitter). 相似文献

Group affiliation plays a key role in shaping individual opinions on public policy issues. Understanding group-related differences may be important for global organizations that depend on broad public acceptance of their policies. Research indicates that people's opinions become polarized to match perceived opinions of their group and that media reports may signal normative opinions group members should adopt. Surveys administered before and after the World Trade Organization's (WTO) 1999 meeting in Seattle indicated significant differences in opinion by group affiliation. Respondents overall held negative views of the WTO before the meeting, and more negative views after the meeting. Business and civic group members were more positive toward the WTO than were human rights and environmental and union group members, reflecting their self-interests. However, contrary to public opinion theory between-group differences in opinion in many cases became less polarized, whereas attention to media coverage served to further polarize only the opinions of union group members. 相似文献

A content analysis was conducted of the posts generated by mass media organizations and public opinion leaders on the Chinese social media platform Sina Weibo to investigate the associations between several communication message cues and opinions about people with depression (N = 102). The study revealed that the posts of the influential users were more likely to be stigmatizing when they communicated stereotypes, but less likely to be stigmatizing or more likely to be supportive when they made personal, genetic and medical, and social and environmental cause and responsibility claims. The posts were also more likely to be supportive if the influential users presented treatment and recovery information. In addition to finding out what communication cues activate the influential users' stigmatizing or supportive opinions, the study also examined and found the impact of the influential users' opinions on their followers' opinions on this issue (N = 8261). The findings showed that the public opinion leaders were more likely than the mass media to express support for people with depression. This support then translated into supportive responses among their followers toward those living with the disease. 相似文献
