This study extends the cognitive mediation model (CMM) by examining the role of social media in cultivating public science knowledge. A sample of 901 Singaporeans was collected through an online survey panel. The results showed that the CMM could be applied to a social media context with a focus on science literacy. Specifically, the findings indicated that people with higher levels of surveillance gratification and social utility motivations tended to pay more attention and to elaborate more about science news that they encounter on social media. Likewise, people with greater social utility motivation tended to engage in greater interpersonal discussions on social media. Notably, attention to news on social media had an indirect association with science knowledge through news elaboration and interpersonal discussion on social media. Implications for theory and practice for science communication were discussed. 相似文献

This study advances the cognitive mediation model (CMM) by examining the factors behind acquiring knowledge about climate change. Based on a nationally representative survey of Singaporeans (N?=?1,083), this study supported the original CMM. The extended CMM showed that surveillance gratification was positively associated with traditional and online media attention, while social utility was positively associated with online media attention. While attentions to traditional and online media were positively associated with elaboration, online media attention was positively associated with selective scanning. Elaboration was positively associated with knowledge. Implications for theory and practice were discussed. 相似文献

A survey of 2,296 people from 6 nations (Canada, China, Germany, Japan, Sweden, and the United States) deciphered uses and gratifications for consuming content on a variety of media platforms during the 2018 Pyeongchang Winter Olympic Games. Results indicate that media diets significantly differed by platform and device, all 16 uses and gratifications were significantly different by nation, and the 2 inverse predictors of Olympic media consumption relate to the desire to interact (companionship and relationship building), whereas none of the 4 direct predictors (entertainment, arousal, competition, and Schwabism) pertained to interpersonal aims. Findings bifurcated by media platform as well; for instance, the inverse predictor of smartphone use—passing time—was a direct predictor of television use. Moreover, relationship building and habitual use were direct predictors of tablet use for Olympic consumption yet were both inverse predictors within the television realm. Implications for uses and gratifications and cross-nation media research are advanced. 相似文献

This study applies the knowledge gap hypothesis to examine the direct and interactive influence of socioeconomic status, mass media, and interpersonal discussion on public knowledge of the H1N1 flu pandemic in Singapore. Using a nationally representative random digit-dialing telephone survey of 1,055 adult Singaporeans, results show that attention to newspapers was not associated with a widened knowledge gap about the H1N1 pandemic between the high and low socioeconomic status individuals. Conversely, attention to television news and interpersonal discussion were associated with a narrowed knowledge disparity between the high and low socioeconomic status individuals. Findings suggest that the knowledge gap hypothesis was not supported in this study. Instead, results suggest that attention to television news and interpersonal discussions were associated with a reduced knowledge gap. Household income and risk perceptions were also found to be positively associated with public knowledge about the H1N1 flu pandemic. Both theoretical and practical implications were discussed. 相似文献

Numerous health communication studies have highlighted the importance of factual knowledge as an antecedent to health behavior, but few have explored other dimensions of health knowledge, such as structural knowledge. This study seeks to fill this gap by investigating conceptual differences between these two kinds of knowledge in the context of breast cancer in Singapore, and find out how communication and motivational factors are related to them. Using a nationally representative random-digit-dialing survey of women aged 30–70 (N = 802), results showed that interpersonal communication and elaboration were associated with both knowledge types. Attention to online health news and the level of risk perception were positively associated with structural knowledge but not factual knowledge. Theoretical and practical implications for health communication were discussed. 相似文献

This article examines hostile media perceptions (HMPs) by building on recent trends in hostile media research. Our study considers the effects of people’s cognitive as well as their affective involvement on HMPs. As the media landscape has changed fundamentally since HMPs were initially identified, the role of social media is explored more profoundly. In addition, this article not only examines the direct effects of involvement and communication activities but tests for indirect effects of involvement mediated through media use and interpersonal discussions. Using data simultaneously collected from two online surveys conducted in Germany and the German-speaking part of Switzerland, the findings strengthen previous evidence that affective involvement is a stronger predictor of HMPs than cognitive involvement. In contrast, media use and interpersonal discussions had only marginal direct effects. The study provides initial evidence for the indirect effects of involvement mediated through exposure to online user comments and interpersonal discussions. 相似文献

Communication scholars have conflicting views on the relationship between exposure to science news and knowledge, and its subsequent influence on attitudes. Such mixed sentiments could arise from the vague definition of knowledge. Therefore, this paper explicates science knowledge into factual knowledge and subjective knowledge. It also compares the mediating roles of both types of knowledge between news attention and public support for science and technology (S&T). A survey of 967 Singaporeans showed that news attention was positively related to both factual and subjective knowledge. The findings revealed a stronger relationship between subjective knowledge and news attention than factual knowledge and news attention. Additionally, factual knowledge was positively related to public support for S&T, but subjective knowledge was negatively related to public support for S&T. The contrasting directions of these associations demonstrate that factual and subjective knowledge are two distinct dimensions of knowledge. Practically, the findings can inform policymakers and communication practitioners about effective public education and engagement initiatives. This study also provided guidelines for newsmakers in news reporting about S&T. 相似文献

Social media’s potential for political and social discussion provides great promise since deliberation is key for democracy. Unfortunately, there is a problematic presence of incivility in conversations on digital platforms. We conducted an experiment to examine the effects of this phenomenon, driven by the elaboration likelihood model. Each of our four conditions showed a media outlet’s Facebook post with a story about genetically modified organisms and a comment section beneath with one of the following: a civil discussion, an uncivil discussion, an uncivil conversation with metacommunication encouraging civility, and a control group. Results revealed a mediated relationship of exposure to civil and metacommunicative comments on willingness to engage in a discussion through mental elaboration. We also found evidence of modeling behavior for civility and metacommunication. 相似文献

The media have identified the past decade as “the age of distraction.” People today find it harder to work on long, sustained tasks because distractions are eroding their attention spans, fostering a culture of discontinuity. Fields as diverse as psychology, business, education, human-computer interaction, and communication studies have produced a wealth of studies on interruptions, distractions, and multitasking—research that has important implications for reference librarians. The nature of our jobs invites interruptions by the public, requires familiarity with the latest technology, stimulates curiosity about a broad range of subjects, and demands adeptness at multitasking—all factors that can atomize attention. 相似文献

Public agencies need to distribute information to their manifold audience quickly and directly. The emergence of social media platforms has sparked positive projections about future government-public interactions via the internet and almost every EU agency has created social media presences on the leading social media platforms. However, social media accounts of agencies receive strongly varying amounts of public attention and therefore display varying degrees of usefulness to connect with the public. This research examines which factors influence how much long-standing and temporal attention social media accounts of EU agencies receive. Using an extensive Twitter dataset of EU agencies and a new methodology that employs supervised text classification through the novel BERT language model to classify agency tweets, possible explanations of social media attention are tested. Results show that long-standing social media attention (i.e., size of the followership) is mostly explained by salience in traditional news, account age, and tweeting frequency, whilst a more interactive communication style tends to yield more temporal attention (i.e., number of retweets). The findings underline previous assumptions that employing a more interactive communication style maximizes public organizations' potential to connect with their audiences on social media. 相似文献

The current study advances the literature on psychological reactance theory by examining the moderating role of message elaboration on the reactance process. Participants (N = 512) were randomly assigned to a message condition (freedom-threatening vs. non-freedom-threatening language) in a between-subjects quasi-experimental design. Message elaboration was not manipulated but rather varied naturally. Two topics were examined (energy conservation and organ donation). Results demonstrated that freedom-threatening language was positively associated with perceived freedom threat for both topics. No interaction effect of message elaboration and freedom-threatening language on perceived freedom threat was observed for either topic. Findings are discussed in terms of the theoretical and practical contributions of the current study. 相似文献

Informed by the Cognitive Mediation Model of media learning, this study explores how self-efficacy and information-processing strategies jointly impact the learning of health knowledge. Using survey data (N=1409), the study examines the roles that self-efficacy, motivation of media use, news attention, and elaboration play in acquiring knowledge about swine flu during the 2009 global pandemic crisis. Results support the hypothesized relationships among self-efficacy, motivation, attention to and elaboration of swine flu news, and knowledge about the flu. Implications of the findings to advance the research in mediated cognitive learning are discussed. 相似文献

The Role of Engagement in Learning From Active and Incidental News Exposure on Social Media 总被引：1，自引：0，他引：1

The growing reliance on social media as news platforms may lead to more passive news consumption but also offers greater potential for engaging in news. This study investigates the role of engagement with news content on Facebook and Twitter between news exposure and current events knowledge. An online survey (N = 400) tests the relationships between social media news seeking, incidental exposure to news on social media, engagement in shared news content, cognitive elaboration, and current events knowledge. The results show that both active seeking of and incidental exposure to news on both sites are linked to engagement, which is linked to greater cognitive elaboration about the content. Furthermore, engagement mediates the relationship between both types of news exposure and cognitive elaboration. However, engagement and elaboration are not related to knowledge. These results indicate that the key role of social media in news content is not knowledge gain but the ability to engage users who may be passively receiving news on these sites. This study extends the cognitive mediation model of learning from the news in the context of current social media, with updated news consumption norms such as engagement with news on these sites, and incidental news exposure. 相似文献

The human voice is a major component of popular media, yet its role in people’s media experiences has received minimal research attention. To address this gap, we investigated how recognition of celebrity voices interacted with perceptions of and engagement with audio-only media. After listening to famous actors reading stories, participants indicated whether they recognized each voice, rated its pleasantness, and completed parasocial interaction and narrative transportation measures. Results indicate that recognized voices were perceived as more pleasant. Additionally, vocal pleasantness was associated with increased parasocial interaction and transportation. Findings partially support the prediction that vocal recognition enhances parasocial interaction. 相似文献

The media are normatively expected to play significant roles in conflictual discussions within national and international communities. As previous research shows, digital platforms make scholars rethink these roles based on media behavior in online communicative environments as well as on the structural limitations of the platforms. At the same time, traditional dichotomies between information dissemination and opinion formation roles, although seemingly universal, also vary across cultures. We look at four recent conflicts of comparable nature in the United States, Germany, France, and Russia to assess the roles that legacy media have performed in the respective ad hoc discussions on Twitter. Our approach differs from previous studies, as we combine content analysis of tweets by the media and journalists with the resulting positions of the media in the discussion graphs. Our findings show that, despite the overall trend of the “elite” and regional media sticking to information dissemination, online-only media and individual journalists vary greatly in their normative strategies, and this is true across countries. We also show that combining performance in content and social network analysis may allow for reconceptualization of media roles in a more flexible way. 相似文献

Drawing on the impression management theory, this study examined the effect of online media platforms, social network sites (SNSs) versus non-SNSs, on the intention to join a cause. The online experimental study discovered that the SNS was more effective in increasing the intention to join a cause than the non-SNS. The findings also demonstrated the mediating role of the perceived visibility of joining the cause and the moderating role of public self-consciousness on this effect. Further, self-cause image congruence positively influenced the intention to join the cause, while it did not moderate the effect of online media platforms. 相似文献
