Research suggests that individuals use cues about the popularity of a cause or group to make judgments. This bandwagon phenomenon has found particular support in online contexts. However, perceptions regarding the group may also depend on the identity of those supporters. We employed a 2 × 2 × 2 experiment to test the effect of number of affiliates and affiliate race and age on feelings toward the group, its page, and intended support. Results suggest that feelings are not subject to a consistent bandwagon effect but rather are moderated by race, with White participants exhibiting more positive feelings when seeing a page with few Black affiliates or many White affiliates. This result contrasts with findings for age, which serves to moderate only intended page use.  相似文献

This study examines credibility perceptions in online consumer reviews. Specifically, this work investigates the effects of review emotionality (high vs. low), review valence (positive vs. negative), and individuals’ need for affect on source credibility and information credibility. In an online experiment, U.S. adults (N = 327) viewed a product review from Amazon.com varied across four experimental conditions. Results indicate that high-emotionality reviews are perceived as lower in source and information credibility compared to low-emotionality reviews. A moderated mediation model was tested with the source credibility dimensions as possible mediators of information credibility and need for affect as a moderator for the effects of review emotionality. The effects of emotionality on information credibility were significantly mediated by source trustworthiness, and this mediation was moderated by participants’ need for affect, with the credibility-hampering effects of emotionality found only among participants with low and moderate levels of need for affect.  相似文献

Bioecological systems theory provides a framework to understand how factors in the child's environment contribute to parent-child differences in estimations of how often children are helped by their Internet use. A national sample survey of 456 matched parent-child pairs investigated how parents-child relational factors, parental attitudes toward the Internet, and the bio-ecology of the child, are related to differing perceptions of the frequency of using the Internet to seek help with homework assignments, to aid in identity development, and to find health information. While previous research shows that parents underestimate risky online behaviors, we investigate whether parent-child differences will emerge in regards to how often the child engages in the behaviors under investigation here. The findings show that parents overestimate these online activities, suggesting they are biased in their estimations. Parent-child relational factors emerged as predictors of parental overestimation for each of these online activities, with trust perceptions as the most consistent predictor. Parental attitudes toward the Internet predicted parent-child differences in perceptions of how frequently the child used the Internet for help with homework and identity development, while the bioecology of the child was only predictive in the case of using the Internet for help with homework.  相似文献

This experimental research examines how different presentation modalities in presidential debates and post-debate spin influence the ability to form evaluations about candidates' character, shape perceptions of their incivility, and alter judgments of political trust and news credibility. Results indicate that these experimental factors work together to encourage character judgments, diminish perceptions of candidate civility, and reduce levels of trust in government. In addition, political talk conditioned experimental effects on perceptions of news credibility, with the adverse effects of split screen presentations concentrated among those who talked about the debate. Thus, the negative effects of “in your face” politics conveyed by the “split-screen” modality appear to be most pronounced among those primed to think about performance and those attuned to politics through interpersonal talk.  相似文献

ABSTRACT

Many journalists and industry observers lament that aggregating news underneath sensational headlines will erode credibility and turn off readers. While some scholarly work has studied journalists’ perspectives of this practice, little has been done to understand what audiences think of aggregation and clickbait. This study uses published original and aggregated news articles as stimuli in two online experiments to test readers’ perceptions of news aggregation and clickbait. Aggregation itself has little effect on perceptions of credibility and quality; instead, writing proficiency is more closely linked to these perceptions. Results also suggest clickbait headlines may lower perceptions of credibility and quality.  相似文献

Can the comments of a few viewers on social media affect viewers’ perceptions of audience sentiment or their own program enjoyment? If so, do the effects of comments vary based on their valence or placement during programming? We conducted a 2 (positive vs. negative tweets) x 2 (beginning vs. end of program) factorial experiment with an additional control condition (N = 196) to answer these questions. Negative comments undermined perceived bandwagon support for the program and reduced enjoyment, regardless of contextual or trait moderators. Findings suggest that the effects of social television may be attributable to systematic processing of bandwagon cues.  相似文献

As the perceived credibility and availability of conventional sources of applicant information wanes, employers increasingly use online information to evaluate prospective employees' fit. This qualitative study explores how employers communicatively frame online screening—or cybervetting—to inform fit assessments during personnel selection. Findings suggest that employers legitimize cybervetting by framing the practice as risk work (i.e. due diligence and professional identity work), reputation management, efficient, fun, and transformative. Findings evidence shifting understandings of how fit assessments occur and what constitutes a “good fit” and an ideal worker as employers extend organizational surveillance beyond conventional work roles and contexts. Recommendations include assessing cybervetting's effectiveness at accomplishing risk, reputation, and efficiency goals; complicating singular notions of identity; considering bona fide information environments when developing employment legislation; and expanding training to improve employers' and workers' socio-technical and communicative competencies.  相似文献

Human behaviour is complex and demographics are insufficient to understand information behaviour. More nuanced analyses are required to understand the factors that drive action. Focusing on digital archiving and online protection strategies as manifestations of information behaviour, factors that influence perceptions of online risk were investigated. The relationship between perception and behaviour was analyzed by focusing on people’s risk responses and their archival habits. Using Bates’ theory of Information Behaviour, information behaviour paradoxes, what people do versus what they say they would do in online situations, were analyzed. By applying a mixed-method approach to 101 semi-structured interviews, individuals’ self-perceived internet skills and having a third-party negative experience are two key factors that influence perceptions of risk online. A three-part typology of internet users (cautiously optimistic offliners, confident onliners, and utopic onliners) is introduced. Perceptions of online risk have consequences for information behaviour and informs a theoretical modification.  相似文献

This research explored the perceptions of university students about the credibility of information being shared on Facebook. The data were collected using an online questionnaire from university students who were Facebook users. A total of 325 usable responses were received which were analyzed using SPSS. The results revealed that these students perceive information shared on Facebook as credible and of good quality. The source credibility, medium credibility, and information quality had positive and significant relationships with each other. The age, social background, and educational level of students appeared to predict the credibility of information shared on Facebook. These results are useful for information professionals and social media managers in extent to understand and cater to the demands of information consumers. These findings would also be helpful for teachers, information providers, and researchers to understand the perspectives of developing countries' students on the credibility of social media information. Furthermore, this study is supposed to be a valuable addition in existing literature which could provide guidelines for novice researchers, interested in exploring the area, especially in the context of Facebook users in a developing country's context.  相似文献

This article explores perceptions of news credibility for television, newspapers, and online news. A survey was administered to a randomly selected sample of residents in Austin, Texas, to assess people's attitudes toward these 3 media channels. Contingent factors that might influence news credibility perceptions, such as media use and interpersonal discussion of news, were incorporated into the analysis. Findings suggest that people are generally skeptical of news emanating from all 3 media channels but do rate newspapers with the highest credibility, followed by online news and television news, respectively. Furthermore, opinions about news credibility seem to be correlated across media outlets. The data also show a moderate negative linkage between interpersonal discussion of news and perceptions of media credibility for television news but not for newspapers. When controlling for basic demographics, a positive correlation was found between interpersonal communication and online news credibility. Finally, a marginal association was noted between media use and public perceptions of credibility across all 3 media channels.  相似文献

Background: While the Internet is a popular source of health information, health seekers’ inadequate skills to locate and discern quality information pose a potential threat to their healthcare decision‐making. Objectives: We aimed to examine health information search and appraisal behaviours among young, heavy users of the Internet. Methods: In study 1, we observed and interviewed 11 college students about their search strategies and evaluation of websites. In study 2, three health experts evaluated two websites selected as the best information sources in study 1. Results: Familiarity with health websites and confidence in search strategies were major factors affecting search and evaluation behaviours. Website quality was mostly judged by aesthetics and peripheral cues of source credibility and message credibility. In contrast to users’ favourable website evaluation, the experts judged the websites to be inappropriate and untrustworthy. Conclusion: Our results highlight a critical need to provide young health seekers with resources and training that are specifically geared toward health information search and appraisal. The role of health seekers’ knowledge and involvement with the health issue in search effort and success warrants future research.  相似文献

Research has shown that message frames can shape a reader’s subsequent judgments on political issues. In the online news environment, additional cues outside the story may be present that can affect the power of the frame. This online experiment investigates the role of repetitive cues in the framing processes using news editorials and their accompanying recommended headlines that repeat the editorial’s frame. Results suggest that regarding issue-related attitudes and emotions, consistent frame repetition reinforced the effects of the original article when the frame’s relevance to the readers was high but undermined the article’s impact when the relevance was low. Implications for framing studies and online news consumption are discussed.  相似文献

The purpose of this study was to examine how patients' perceptions of source credibility related to their satisfaction with the quality of medical care they received and satisfaction with their physician. Patients' perceptions of the competence and caring dimensions of source credibility were analyzed for physicians, nurses, and support staff members. Three hypotheses were proposed and supported. Results indicated that higher perceptions of competence and caring for each member of the medical team were related to more patient satisfaction. This paper discusses the importance of the doctor-patient, nurse-patient, and support staff-patient relationships in light of the findings.  相似文献

This exploratory research examines processes pertaining to how parody humor can influence perceptions of political figures in terms of credibility and, more broadly, general political trust. An online experiment was conducted in which select participants were exposed to a parody of former New York governor David Paterson. The results demonstrate that, in tandem with parody-induced sympathy, humor enjoyment can influence perceptions of a parody target's credibility and general political trust. In addition, a sympathetic predisposition is shown to positively predict responses of sympathy to a parody message. Furthermore, serial mediation analyses highlight how a sympathetic predisposition can indirectly influence various perceptions of a parody target, as sequentially mediated by responses of sympathy and enjoyment. In sum, this research is valuable for illuminating how individual differences and affective responses to political parody representations can affect various political perceptions.  相似文献

With the rapid development of interactive communication technology, the Internet is a major source of news and also plays an important role in connecting individual members of society. However, Internet users may have different perspectives on whether the Internet positively functions as a medium for public deliberation. Based on the assumption that being exposed to information on public affairs is a crucial step for one's civic engagement, this study explores how individuals’ motives related to news consumption, elaborative online news reading, and online news sharing influence their perceptions of online deliberation using structural equation modeling method (N = 998). The study finds significant relationships between news consumption motives and elaborative news reading and sharing behaviors, but only elaborative reading behavior had a significant effect on one's perceptions of online deliberation. The implications of these findings are discussed.  相似文献

Viewing a hostile media bias against one’s group (e.g., political party) is a perceptual effect of media use. When it comes to the portrayal of political parties in the United States, prior research suggests that both Democrats and Republicans see mainstream media coverage as favoring the other side, regardless of the orientation of the political news coverage. Although prior research has not identified all factors that make this perceptual bias more likely, or at explaining how or why this perceptual effect occurs, we do know that it is related to one’s group identity. In this study, we examined salient predictors of hostile media bias during the 2012 presidential campaign. Individual (i.e., political cynicism) and group identity related (i.e., group status, intergroup bias, political ideology) differences of media users predicted such perceptions. But, the medium selected for political information about the campaign also mattered. The use of two media in particular—TV and social networking sites—appear to have blunted hostile media bias perceptions, whereas the use of two other media—radio and video sharing sites—appear to have accentuated perceptions that the media were biased against one’s party  相似文献

ABSTRACT

By administering an online experiment, this study examined how source and journalistic domains affect the perceived objectivity, message credibility, medium credibility, bias, and overall journalistic quality of news stories among an adult sample (N?=?370) recruited using Amazon’s Mechanical Turk (MTurk) service. Within the framework of the cognitive authority theory, the study found auto-written news stories were rated as more objective, credible (both message and medium credibility), and less biased. However, significant difference was found between a combined assessment condition (news stories with source and author information) and a message only assessment condition (news stories without source and author information) in the ratings of objectivity and credibility, but not bias. Moreover, significant differences were found in the objectivity and credibility ratings of auto-written and human-written news stories in the journalistic domains of politics, finance and sports news stories. In auto-written news stories, sports news stories were rated more objective and credible, while financial news stories were rated as more biased. In human-written stories, financial news stories were rated as more objective and credible. However, political news stories were rated as more biased among human-written news stories, and in cases where auto-written and human-written stories were combined.  相似文献
