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

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

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

This study tests the role of second screening during election news consumption in factual political knowledge. Data from an online survey conducted before the 2016 U.S. presidential election show that task-irrelevant second screening during election news consumption on television is negatively related to factual political knowledge, whereas the influence of task-relevant second screening is positive. Data also show that the relationships between task-relevant and task-irrelevant second screening and factual political knowledge are moderated by how much attention one pays to election news on television. 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 uses the contemporary debate over agricultural biotechnologyto conceptualize a theoretical model that can be used to explainhow citizens reach judgments across a range of science and technologycontroversies. We report findings from a mail survey of NewYork State residents that depicts a ‘low information’public relying heavily on heuristics such as value predispositions,trust, and schema to form an opinion about agricultural biotechnology.Science knowledge does play a modest role, with the news mediaserving as an important source of informal learning. Contraryto expectations and past research, we do not find any directeffects for news attention on support for agricultural biotechnology.Deference to scientific authority is a central value predispositionshaping support for agricultural biotechnology. Positively correlatedwith education, deference to scientific authority is the strongestinfluence on support for agricultural biotechnology in our model.Part of the variable's influence is direct, but part of it isalso indirect, as deference to scientific authority is a keypredictor of both trust in the sponsors of biotechnology andgeneralized reservations about the impacts of science.

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

In this paper we explore the relationships between public interestin, knowledge of, and attitudes towards science and technologyand the level of industrialization in 12 countries of the EuropeanCommunity. Using the 1989 Eurobarometer survey no 31 (N=11,678),we constructed four scales measuring interest, knowledge, generalattitudes to science, and support for EC funded science foreach of the 12 EC countries. We found that overall factual scientificknowledge correlates moderately positively with interest andattitudes to science. For example the Netherlands and GreatBritain have relatively high levels of knowledge, interest,and support for science in general. Spain and Greece have relativelylow levels of knowledge, interest, and support for science ingeneral. However, the simple correlation hides more complexrelationships. First, the variance within and across countriesof knowledge, attitudes and interest increases with nationallevels of knowledge. This indicates greater degrees of polarizationof both support and interest. Second, the data indicates a post-industrialismeffect: knowledge, interest in, and attitudes to science showa curvilinear relationship with levels of industrialization.The decline of interest in science and the less positive attitudesin highly developed countries requires further exploration.Third, we found, that the consistency of the knowledge and theattitude measures declines as the national level of knowledgeincreases. We suggest that this reflects a knowledge-ignoranceparadox and knowledge specialization among informed populations.Support for EC level science follows a different pattern. Wefound that France, Italy, and Spain show high levels of supportfor EC level science. This is not the case in Great Britainand Germany. The pattern suggests that attitudes towards ECscience are formed on the basis of national level scientificstrength: if the national science base is strong, EC scienceinitiatives find less support and vice versa. These findingsrepresent a first step towards a comparative assessment of publicunderstanding of science in EC countries. 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 examined the role of three personality characteristics, Psychoticism, Extraversion, and Neuroticism (PEN), on viewers' level of attention to five different genres of television programming: news, soap operas, reality shows, talk shows, and crime dramas. A survey of 381 college students showed psychoticism to be negatively related to attention to news and reality show programming. There was a positive relationship between extraversion and attention to reality programming. Finally, neuroticism was positively associated with attention to all genres assessed. The implications of these findings for future research are discussed. 相似文献

Using cross-sectional data from the 2008 National Annenberg Election Survey, this study tests 2 models that explicate the relationship between politically likeminded media use and political polarization and participation. The knowledge model suggests that the effects of exposure to likeminded media on individuals’ attitudinal polarization and political participation are mediated by knowledge of candidate issue stances. The belief model proposes that likeminded media use indirectly influences political polarization and participation via political beliefs. The results provide evidence that individuals’ beliefs mediate the influence of likeminded media consumption on attitudinal polarization and participation, but there was no support for the knowledge model. These findings indicate that individuals who consume politically likeminded news tend to develop polarized attitudes and are motivated to participate in political activities by forming biased beliefs associated with candidates rather than by gaining factual issue knowledge. 相似文献

Cable news schedule today is programed with a transition between objective reporting and subjective commentary. With this in mind, we address the question: to what extent does political ideology impact one’s estimation of factual content in the monologue of a partisan news host? Going beyond direct effects, we analyze two moderated mediation models, using news host as moderator and using parasocial relationship and source credibility as parallel mediators. Results show like-minded partisanship with a news host led to higher estimates of factual content, and this effect worked indirectly through credibility perceptions. Additionally, this process occurred more intensely for conservatives. 相似文献

Scientific news is one of the major resources that help the public to understand new scientific knowledge. The latest technology in research and development primarily utilizes English as the language of communication in academic journals and scientific communities. Compiled science news therefore has become a major agent for many non-Western societies to understand the latest technological developments. For this reason, this study aimed to investigate the meaningful change among transforming processes of imported science news from ‘original scientific research’ and ‘overseas news reports,’ to ‘domestic compiled science news.’ The research findings showed that scientific knowledge categories of compiled science news in Taiwan appeared to be apparently unbalanced, and the compiled skills present obvious weaknesses. Furthermore, more seriously compiled science news in Taiwan has continually suffered from the ‘double media distortion’ syndrome. The first distortion appeared from the ‘original scientific research’ to the ‘overseas news reports,’ and the second was from the ‘overseas news reports’ to the ‘domestic compiled science news.’ Such situations are very different from the Western world and could also be a common problem for all non-Western societies. 相似文献
