The current study investigates how social media affordances influence individuals’ source credibility perceptions in the presence of risk information, specifically examining how bandwagon heuristics interact with different identity heuristics at the individual level. The MAIN model and warranting theory serve as the theoretical framework to examine the effects of bandwagon cues and identity cues embedded in retweets and users’ profile pages for health and risk online information processing. A posttest-only experiment with a self-report questionnaire was administered to participants. Results indicate that different online heuristic cues impact the judgments of competence, goodwill, and trustworthiness. Authority cues strongly influenced source credibility perceptions. A reverse-bandwagon effect was observed in influencing source credibility judgments. 相似文献

In this article, we review previous conceptualizations of perceived reality judgments of television content. We argue that the perceived reality literature suffers from conceptual inconsistencies that have the potential to interfere with understanding the research taken as a whole and with the success of future studies. We analyze 3 major variants in perceived realism judgments. The first consists of conceptual dimensions (e.g., magic window and social realism). We argue that labels and definitions have been assigned inconsistently in previous research. Redundancies and inconsistencies are addressed. Six primary dimensions are identified and described. The second is measurement features. We point out that perceived realism judgments may vary in specificity (e.g., the realism of television in general or the realism of a specific program) and object of judgment (e.g., the realism of characters or the realism of issues). The third variant is processing characteristics. Realism judgments may be made while reflecting back, with memory-based judgments, or while viewing, with online judgments. The implications of considering each variant when conducting research are discussed. An overall conceptual structure for perceived reality judgments is proposed. Finally, the application of this organizational scheme to 3 areas of future research is presented. 相似文献

信息源对数字原住民健康信息可信度判断的启发式实验研究 总被引：2，自引：0，他引：2
互联网已成为消费者健康信息搜寻的重要渠道。Web 2.0环境下互联网信息传播的路径和形态嬗变使在线健康信息环境日趋多样与复杂,用户在异质信息源中选择恰当健康信息的难度显著提升。本文基于启发式信息处理视角,从理论层面梳理启发式与健康信息可信度判断之间的内在关联并构建概念模型。在此基础上,采用实验研究法,以受控健康信息文本与启发式信息线索网页框架构建实验材料,并招募高中生群体这一典型的数字原住民作为被试开展实验研究。实验结果表明,各类健康信息来源中的启发式信息线索对数字原住民的可信度判断具有显著影响,特别是机构信息源线索的出现会显著提高数字原住民的可信度评价。数字原住民对机构信息源的可信度评价显著高于商业信息源与社会化媒体信息源,而商业信息源与社会化媒体信息源之间没有显著差别。研究结论有助于进一步理解数字原住民的健康信息行为模式,并为政府部门和公共卫生机构更好地构建健康信息平台提供参考依据。 相似文献

College students' processing of alcohol, smoking, and exercise social norms messages, and related effects on judgments, attitudes toward one's own behaviors, and attitudes toward undergraduates' behaviors were examined using social norms marketing and Expectancy Violation Theory (EVT) (N=393). Receiving statistical social norms messages led to an expectancy violation of the perceived social norm (i.e., a discrepancy between the expected and actual statistic conveyed with a message). Consistent with Boster et al. (), the effect of the message discrepancy on attitudes was mediated by judgments. In accordance with social norms, when participants were provided with a statistic, the majority moved their judgments (but not their attitudes) toward the provided statistic, a result only consistent with EVT in the case of positive violations. The results have multiple implications: (1) social norms messages may work to change judgments, but do not result in consistent attitude change; (2) the process of judgment change functions similarly across message topics, as well as message types (i.e., attitudinal versus behavioral); (3) judgment change does not appear to be the main cause for attitude change upon receipt of a social norms message; and (4) a message‐based expectancy violation does not function in the same way as a violated behavioral expectation. 相似文献

This article explores the relative placement of listening competence within other implicit theories used to form judgments of interlocutor competence. Two studies explore the relations among communicative competence, social skills, and listening competence and various attributes that are purportedly implied by each. Study 1 reveals that very few attributes are uniquely related to any one implicit theory. Study 2 demonstrates that listening competence is located subordinately to communicative competence. The discussion focuses on what these studies add to the competency literature and how future research can continue to explore implicit competency theories. 相似文献

Does an image facilitate the sharing of negative news on social media? An experimental investigation
《Library & information science research》2021,43(4):101120
Negative news on social media is always disseminated promptly and widely which leads to negative economic and social outcomes that render a practical research agenda necessary to understand user sharing decisions. Moreover, news posted on social media usually includes images, but little is known about the role of such images in shaping user decisions to share negative news. To fill this gap, the humans' affective–cognitive model of information processing (HACIP) was developed to explore the effects of images on the sharing of negative news and to investigate the contingent role of images in the sharing decision. To test the model and hypotheses, a scenario-based online experiment was conducted, which yielded 285 valid responses. Analysis results indicate that images in negative news induce users' negative emotion and arousal, which influence their sharing decision. Further, the presence of images strengthens the effect of negative emotion and weakens the effect of information uniqueness. Thus, this study contributes to the literature by identifying the distinct role of images in information processing and by proposing a brand-new framework to explore user sharing of negative news. 相似文献

The present study examines how language use (e.g., personalized vs. depersonalized language) and modality (e.g., tweets vs. Facebook status updates) influence source credibility interdependently. A total of 257 participants read personalized or depersonalized health messages embedded in mock-up tweets or Facebook status updates. The results show that users perceive depersonalized tweets as more credible than depersonalized status updates posted on Facebook. On the other hand, personalized status updates on Facebook generate higher credibility judgments than personalized tweets. The findings are discussed in light of the MAIN model as well as the preconceived user expectations and communication norms of social media. 相似文献

Violations of expectations have been advanced as an explanation for how people make veracity judgments, and previous research has found that unexpected weird behavior is rated as less honest than expected normal behavior. The current experiment (N = 128) varied norms and expectations independently to test four alternative models of veracity judgments. The models included a normative expectation model, an expectancy violation sufficient model, a model based on Expectancy Violation Theory, and a norm violation model. The data were consistent with a norm violation model. Aberrant behavior, whether expected or unexpected, was rated as less honest than normative behavior. Neither expectation violation nor actual message veracity affected deception judgments. These data provide additional evidence of the primacy of behavior over prior expectations in the evaluation of face to face communication. 相似文献

This study tests the relative importance of different factors of television narratives in how they influence people's judgments of how violent those narratives are. After watching 1 of 3 videotapes of a violent narrative, 99 college students answered a series of questions about their interpretations of the violence. It was found that participants' judgments about the degree of violence in the narratives were more strongly associated with their perceptions of the graphicness of the violent acts and the harm to the victims than with other factors such as the number of violent acts or the seriousness of those acts. Thus, people's judgments of the degree of violence in television programs differs from researchers' conceptualization. Implications of these differences are discussed. 相似文献

Members of small groups do not always mention available information, and this leads to inferior decision making. A local model of participation was applied to information sharing discussions to evaluate the extent to which task-relevant judgments are related to comments that contain unique (i.e., data that only one member knows) and shared (i.e., known to all members) information. In addition, the model was applied to only “incorrect” groups, ones that did not choose the optimal solution. Findings revealed that the local model applied to incorrect groups in the sense that shared information figured prominently in the development and maintenance of judgments. Unique comments, however, played a limited role in the process. Other findings showed that shared contributions were not associated within groups, indicating somewhat skewed rates of participation. Discussion focuses on the distribution of variance related to judgments. 相似文献

This study examined the influence of prolonged exposure to soap opera on character dispositions and real-world moral judgments. Eight groups viewed from 0–7 weeks of soap opera prior to a final week after which participants completed measures of disposition towards show characters as well as perceptions of morality in real-world situations. Results demonstrated the effect of prolonged exposure on both the polarization of dispositions toward characters and a trend in moral judgments toward social convention. These findings highlight the role of disposition within social cognitive theory, and the importance of dispositional considerations in understanding learned morality. 相似文献

American newsrooms are adopting social media as an innovation for greater engagement. However, several organizational and individual factors may affect the extent to which news outlets adopt social media innovations. In particular, there is assumed to be a divide among different age groups of journalists in embracing social media. Utilizing a structural equation modeling (SEM) analysis, the study seeks to understand how social media culture in newsrooms affects journalists’ strategies of taking social media as an innovation, and how journalists of different age groups differ in the SEM model fit. The analyses indicated Twitter engagement mediates social media culture and journalists’ attitude toward social media. However, that was not the case with Facebook. Additionally, while younger journalists favored Twitter, older journalists embraced Facebook and middle-aged journalists adopted both Facebook and Twitter. The analyses showed the more that middle-aged journalists interacted on Twitter, the more they tended to have a positive attitude toward social media. However, the more that younger and older journalists engaged on Twitter, the more they tended to have a negative attitude toward social media. Journalists from all three age groups tended to hold a negative attitude toward social media if they engaged more on Facebook. 相似文献

This study draws on survey data obtained from members in neo-Nazi discussion forums and builds on evidence that participation in these forums exacerbates false consensus, that is, overestimating public support for own views. This study goes further to test whether contacts with dissimilar offline social networks as well as exposure to ideologically dissimilar news media attenuate false consensus and its association with online participation. Contrary to predictions, politically dissimilar networks do not reduce false consensus among the analyzed sample. Exposure to ideologically dissimilar news media, on the other hand, results in more accurate estimates (main effect), but it exacerbates false consensus as resulting from participation in neo-Nazi online groups (interactive effect). Theoretical and practical implications are discussed. 相似文献

Based on the postulates of social identity theory (SIT), this study examined the relationship between exposure to stereotypical media messages regarding race/ethnicity and subsequent social judgments. Specifically, the association between Whites' evaluations of self and other (Latino) as a result of varying media content pertaining to criminality stereotypes was investigated. The findings were partially consistent with the posited relationships. As predicted, negatively stereotypical racial depictions in mediated messages were found to be significantly associated with social judgments. Only limited support, however, was provided for the predictions that increasing levels of racial identification would be related to increased ingroup favoritism, or that esteem would be enhanced from this mediated process of intergroup comparison. 相似文献
