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

Many have noted the immense potential of social media as a catalyst for political engagement. While we know a great deal about the people who use social media for politics, and even why they do it, we know very little about when, or under what conditions, political uses of social media actually occur. In this article I extend interpersonal goals theory to examine when political social media use happens. Results suggest that, above and beyond cognitive political engagement, interpersonal goals contribute significantly in explaining political behaviors on Facebook. I find that political posts entail greater affective and interaction-related risks than following political pages or updating one’s profile, while “liking” political posts affords users a low-cost/low-reward strategy for managing interactions. As such, this study provides evidence that political expression on Facebook takes several distinct forms. 相似文献

This study of media use during the 2012 presidential election examines whether online use, partisanship, and perceptions of media bias predict time spent with traditionally delivered media. Traditional media lost ground to online sources. Moreover, Obama supporters spent more time with liberal media, Romney backers with conservative media, and regardless of support, attention to neutral media increased. Respondents who thought the media were biased against Obama spent less time with conservative media and more with liberal ones and neutral CNN, while those who judged the media as hostile to Romney spent little time with liberal and neutral media. 相似文献

Links among demographics, motivation for using the Internet, cognitive and affective involvement, and Internet dependency were investigated. By integrating uses and gratifications theory and media dependency research, motivation was found to play a more important antecedent role in explaining Internet dependency than demographics, and cognitive and affective involvement mediated the relationship between motivation and Internet dependency. This finding supported the uses and gratifications argument that certain factors intervene in the media uses and effects process between motivation to communicate and outcomes of communication behavior such as media use. 相似文献

This research—a pilot study on the cognitive mediation model (CMM) in Singapore—seeks to revisit and test the applicability of an extended CMM in the context of nanotechnology by examining perceived familiarity as a separate outcome variable in addition to factual knowledge. A cross-sectional survey was administered to a nationally representative sample of 719 adult Singaporeans. Results demonstrated partial support for the hypothesized CMM. First, elaboration was positively associated with both factual knowledge and perceived familiarity, whereas interpersonal discussions about science was associated only with familiarity. Results also showed differential relationships between attention to media platforms (traditional vs. new media) and reflective integration (composed of elaborative processing and interpersonal discussion); whereas attention to science reporting in newspapers and science television programs were associated with elaboration, media attention across all platforms were associated with interpersonal discussions. Theoretical and practical implications are discussed. 相似文献

This study examines relationships among interpersonal informational trust and openness with Internet-based political activities and attitudes. Conceptually, it proposes the categorization of online spaces and activities as consumption or interaction types, and classifies interpersonal informational trust within inner and outer circles. Interpersonal informational trust was found to be positively associated with perception of online activities as political participation. It also was associated with use of all types of online media for purposes of political communication, but mostly with online spaces that require interaction with others. Interpersonal political openness showed positive association with the use of interactive-type Web sites for purposes of political communication. 相似文献

The topic of childhood vaccinations has received much news media attention recently, prompting scholars to examine how the public has responded. In light of this news, and the deep divide that seems to exist between parents who support childhood vaccinations and those who do not, this study examines how and why individuals may involve themselves in communication about vaccinations, particularly on social media or in other online environments. Focusing on the concept of communicative action and drawing from spiral of silence and other research, a survey of mothers (N = 455) found that those who do not support childhood vaccinations are more likely to engage in communication about the issue, including information seeking, attending, forefending, permitting, forwarding, and sharing. In addition, issue importance and affective and cognitive involvement help drive communicative action regarding childhood vaccinations, which could affect public opinion or public perceptions of the issue. Theoretical and practical implications are discussed. 相似文献

The success of online communities depends heavily on the providers' abilities to motivate potential users to adopt the service and to actively participate. Because research in this field of media economics is rare, especially with regard to newly established communities, this study analyzes what drives community adoption and how direct and indirect financial incentives influence user participation. Extending Ajzen's (1991) Theory of Planned Behavior, this article shows, in 2 empirical studies, that network size significantly affects adoption in newly established communities. The results of the first study indicate a strong effect of indirect financial incentives (saving money) on the intention to adopt. The second study indicates that direct financial incentives (earning money) may well help increase the network's size without altering user motivation through crowding-out effects. It is interesting to note that the presence of direct financial incentives attracts new users, but it does not increase usage. 相似文献

This study examines the role of membership in multiple issue publics by understanding its relationship to media use, online activity, and political knowledge. Using data from Taiwan's 2008 Social Change Survey, the study shows that members of multiple issue publics was positively associated with television watching, political talk show watching, and online news reading. In addition, they were found to engage in specific online activities, including information browsing, information exchanging, information gathering, taking part in forum discussions, and blogging. Therefore, members of multiple issue publics tend to use media with a high level of selectivity and engage in online activities that allow them to express opinions, gain knowledge, or discuss issues with others. A curvilinear relationship was explored and found between multiple issue-public membership and general political knowledge. This demonstrates that individuals' ability to process information may not extend beyond certain boundaries, no matter how many issue publics individuals are involved in. 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

The information intents theory strives to explain how and why information is used. In this research the theory was used to discover what happens when online LIS graduate students exchange and use information in threaded discussions. The primary source of data was 33 discussion threads, in which students exhibited cognitive and affective intents and were influenced by their instructor's immediacy in the online classroom. This research provides insight for LIS education, instructional design, and other disciplines that utilize distance education technologies. 相似文献

This study investigates whether perceptions of the media and the public are related to political participation in Colombia. Communication researchers have built a large body of literature on hostile media perceptions and the projection effect, respectively. This study links these perceptual effects with each other and with political participation. Analyzing survey data from a representative sample of Colombian adults in urban areas, we show a direct relationship between hostile media perceptions and participation but no direct relationship between projection and participation. Hostile media perceptions and projection are negatively related. Results suggest that perceived media bias attenuates projection but increases political engagement. 相似文献

Despite the explosive potential for revenue growth on the Internet, research suggests that the advertising industry remains perplexed about how to reach consumers in this new medium. Drawing from several bodies of literature including diffusion, motivation, and media substitution theories, this study explores potential predictors for online service adoption. Findings indicate that the cognitive and affective gratification-seeking factors were the strongest predictors of likely online service adoption. By contrast, whereas adopter attributes were moderate predictors, the existing adoption cluster and media use attributes were both weak predictors of likely online service adoption. 相似文献

This study examines the mediating effects of information-processing strategies on the relationship between use of local news media, informational use of the Internet, and sources of social capital: interpersonal trust, reciprocity, and associational membership. Analyses of a telephone survey data (n = 546) of American adults show that even though local news media were influential, information-processing strategies were more powerful than attention in explaining learning from local news media about social norms at the individual level. These findings support the usefulness of the cognitive mediation model of information-processing behaviors in examining learning from local news media about social norms. Of the two strategies, elaborative processing played a more important role than active reflection in the mediating process. Informational use of the Internet had a significant and independent effect on associational membership, after demographic, structural anchoring, local media use, and information-processing measures were statistically controlled. 相似文献

Observations of the contemporary news media environment often revolve around the topics of ideological polarization and blurred boundaries between mass and interpersonal communication. This study explores these topics through a focus on the association between ideologically oriented online news use, commenting on online news, and political participation. We hypothesize that both ideological online news use generally and proattitudinal online news use are positively related to political participation and that online news commenting creates “differential gains” by augmenting these relationships. Yet we also hypothesize that counterattitudinal online news use is negatively related to political participation and that online news commenting creates “differential losses” by exacerbating this relationship. Analyses of two independently collected and nationally representative surveys found that frequent ideological online news use, proattitudinal online news use, and commenting are all positively related to political participation. We found no evidence for differential gains as a result of online commenting but only for differential losses—counterattitudinal online news use interacts with commenting to create a negative relationship with political participation. 相似文献
