Although late-night comedy and satirical news programs like The Daily Show have been recognized as important sources of political information, prior research suggests that viewers gain only a limited amount of political knowledge from watching these programs. Drawing from uses and gratification theory and extant research on political information processing, this study examines whether learning from The Daily Show depends on whether viewers orient to the message as news or as entertainment. Results from an online experiment suggest that viewers who orient to a segment from The Daily Show as news or as a mix of news and entertainment invest more mental effort and subsequently learn more than viewers who have a purely entertainment orientation. Further, among viewers with a purely entertainment orientation, providing them with an explicit informational-processing goal increases the amount of mental effort and learning relative to viewers who are given no explicit viewing objective. 相似文献

The study explored the role of second-screen use and binge-watching in moderating entertainment education (EE) effects. A pretest/posttest experiment of 273 viewers of East Los High measured the effects of exposure to three subplots, concerning alcohol abuse, abortion, and immigration. The effect of identification with characters on change in attitudes was significantly moderated by second-screen use and binge-watching. In particular, second-screening tended to enhance the positive impact of identification; whereas, among respondents who binge-watched the show, the effects of identification were weaker. 相似文献

Research on the effects of watching presidential debates tends to show that these messages can foster learning about the candidates' issue positions and influence voters' impressions of the candidates. This study uses a pretest/posttest design to assess more subtle effects of watching a 2000 presidential debate on attitudes and vote intention. Leadership and overall policy stance became more important factors in vote choice after watching the debate. Specific groups of issues also became more important in vote choice. Viewers reacted to the candidates differentially: Bush enhanced perceptions of his character (but not of his policy positions), while Gore improved perceptions of his policy positions (but not of his character). The data also reveal that the debates increased the confidence of vote choices for those who did not change their preferred candidate over the course of this study (which could make them more likely to vote on election day and/or less likely to change their vote choice). This study demonstrates a variety of potentially important effects of watching presidential debates. 相似文献

Entertainment news formats, such as radio talk shows and late-night comedy shows, continue to gain audience interest, while traditional news formats are slowly losing audience members. This study examines audience effects from entertainment news formats by comparing retention, involvement, attention and perceived credibility of information presented in a traditional radio broadcast news format and a nontraditional news quiz show format. Findings showed audiences recalled information from quiz questions significantly better than from the traditional news form. Levels of attention and involvement did not differ, and there were no differences for perceived credibility, suggesting audiences may be increasingly accepting of new formats. 相似文献

Online information literacy instruction: Can it impact learning as effectively as face-to-face instruction? Using a quasi-experimental design, this study examined that in relation to upper-level sociology students; it also considered whether library instruction affected participants’ perceptions of learning formats’ (i.e., online or face-to-face) effectiveness and the academic library's place in their research. Using a pretest/posttest design, no significant learning difference was found between the two instructional delivery formats. However, data suggested that instruction did impact online participants’ perceptions of the academic library as a place for research. Implications of this research and future directions for inquiry are discussed. 相似文献

This study tests how repeated exposure to the same news frame influences political opinions over time. In a survey experiment (N = 296), we repeatedly exposed participants to the same news frame (at the start of the study, after one day, one week, and two weeks) and measured effects on opinions (at the start, after two weeks, and after six weeks). Participants in a control group were exposed only once and the effect was also traced over time. Results show that repetitive framing leads both to stronger and more persistent effects than single exposure. The persistence effects are most evident for individuals with moderate political knowledge. Our study contributes to a more comprehensive model of framing effects in mass communication experiments. 相似文献

Having become fully integrated into the contemporary politicallandscape, infotainment-oriented media extend Americans’traditional news (e.g. newspaper, radio, and television) toinclude a greater number of sources for political information,and in some cases, political mobilization. Given the increasingprominence of infotainment-oriented media in contemporary politics,this study addresses the effects of one particular type of infotainment—late-nightcomedy—during the 2000 presidential campaign. Specifically,we are interested in whether watching late-night comedy showsinfluences viewers’ evaluations of the candidates whohave appeared on these shows; in particular, we investigatepriming as the mechanism by which such influences occur. Findingsfrom the 2000 National Annenberg Election Survey (N = 11,482)indicate that evaluations of candidates are based in part onrespondents’ sociodemographics, perceptions of candidatesto handle certain issues, and their character traits. Therewas a main effect of watching late-night comedy on evaluationsof candidates; more importantly, viewers were more likely thannonviewers to base their evaluations of George W. Bush on charactertraits after he appeared on The Late Show with David Letterman. 相似文献

A statewide survey (N = 564) before Ohio's 2006 gubernatorial election examined political interest, campaign news and advertising attention, and perceived effects of negative political ads. Interest was related to political and negative political advertising attention, which were in turn related to campaign news attention. Candidate preference predicted attention to political and negative political ads; attention to ads significantly predicted perceived effects on self and on others, whereas attention to negative ads significantly predicted third-person differential (other minus self). In addition, individuals polled in this survey admitted that attention to ads and negative ads was having comparable effects on both themselves and others. This finding may be due to the climate surrounding Ohio's gubernatorial race, which instilled a political importance and social desirability that abated the need to disown an effect of negative advertising on oneself. 相似文献

The recent proliferation of online videos captured at the scene of news events begs the question: Do news videos have a meaningful impact on citizens’ political opinions and behaviors that is different than that of news articles? This was examined in an experiment using carefully matched videos and articles about the European refugee crisis. Findings show that articles generated stronger intentions to help refugees than videos, and this was mediated by the depth with which the news story was processed. Despite their increasing prominence and intuitively impactful qualities, news videos do not deliver more powerful effects than news articles. 相似文献

The 2015 refugee crisis has sparked heated polarized debates throughout the globe. Yet, to date, we know too little about the discursive framing of the refugee crisis by various actors on online media, and the effect of right-wing populist messages on stereotypical images of refugees. The extensive qualitative content analysis reported in this paper (Study 1, N = 1,784) shows that the framing of populist politicians and citizens overlap in the problem definitions. However, citizens attribute more responsibility to refugees themselves and perceive that the native people are relatively deprived. Traditional news media are more divided. Overall, tabloid media define refugees as a problem, and broadsheet media frame them as victim. The second experimental study (N = 277) demonstrates that messages that blame immigrants for increasing crime rates activate negative stereotypical images of migrants among people with stronger perceptions of relative deprivation. These messages have the opposite effect among citizens with weaker perceptions of relative deprivation. These findings provide important insights into the political consequences of anti-immigration framing. Online media discourse is generally one-sided, and exposure to anti-immigration messages may polarize the electorate in opposing camps. 相似文献

This study was conducted in Japan to test the ability of COM therapy (Motley, 1995) to reduce public speaking apprehension in a culture that seems particularly performance oriented. In general, participants delivered pretest speeches, responded to a battery of self‐report measures, were exposed to the appropriate treatment or not as called for by the experimental design. Respondents then delivered a posttest speech and completed the self‐report measures. Although systematic desensitization reduced apprehension as expected, COM therapy was not found to reduce public speaking apprehension in this study. The implications of this finding and others are discussed at the end of this report. 相似文献

The biodiversity crisis is not salient to many people. A zoo visit not only provides the opportunity to learn about the issue, but also provides direct experiences with animals that may increase public engagement. The present study used a nonequivalent pretest–posttest design to assess the impact of a zoo visit on conservation knowledge and engagement by comparing 88 visitors entering a zoo in Paris and 84 visitors on their way out. Those who had completed their visit scored higher on conservation knowledge, general concern about threats to biodiversity, and perceived self‐efficacy to protect biodiversity. Notably, conservation knowledge was not highly correlated with the other dependent variables, but self‐efficacy was significantly correlated with environmental concern, behaviour, and behavioural intent. We conclude that a zoo visit does have a positive impact on knowledge and concern, and by affecting self‐efficacy, it has the potential to influence future behavior. 相似文献

Two experiments investigated the influence effects of negative photographs on people's attitudes after reading a news story. Experiment 1 presented an online news emulation to participants showing a story and images (high-emotion/low-emotion/no image) about African famine relief efforts. Experiment 2 replicated the design with a story and images about U.S. involvement in the Afghanistan War. As anticipated, using the predictions of the Affect Heuristic model of judgment formation, the addition of pictures with strong emotional activation had a diminishing effect on people's support for the war in Afghanistan and their support for famine aid. Additionally, decreasing effects were observed in broader attitudes concerning participants' support of a militaristic national policy in Experiment 2. These results are discussed regarding their implications for theories of judgment formation and journalistic practice. 相似文献

This study employed a sequential, mixed-method confirmatory research design to assess the impact of the delivery of library staff asynchronous online training at four levels of instructional intervention and workplace integration on short- and long-term knowledge acquisition/retention, self-efficacy, and job performance. The study utilized a pretest, posttest, and delayed posttest design with 192 staff members from twenty-seven public libraries in the United States completing all phases of the four-month longitudinal study. The study proposed an evidence-based, comparative evaluation framework to discern effectiveness of competency-based online training and the impact of varying online training implementation practices. The study found that all levels of instructional intervention resulted in significant short-term knowledge acquisition and enhancement of self-efficacy, and the three approaches that utilized facilitation resulted in long-term knowledge acquisition and improvement in self-efficacy. The impact on long-term workplace practices resulted in unique findings for small and large libraries. The researchers recommend further research in online training evaluation and best practices in public library online training. 相似文献

People are reluctant to share bad news. Reasons include self-presentation and sensitivity to receiver emotionality. An experiment investigated these reasons during interactions between friends and strangers. Females (N = 330, 165 dyads) gave good or bad news to a close friend or stranger. Time to response was recorded. The MUM effect replicated for both friends and strangers. No main effects for friend/stranger or interaction between friend/stranger and news valence were found. Data were more consistent with a self-presentation explanation. Behavioral data were also analyzed to explore communicative behavior that accompanies the sharing of good and bad news. Limitations and implications are discussed. 相似文献

A two-stage analysis examined visuals in news related to governmental surveillance, finding that just as surveillance has shifted from visual evidence to dataveillance, journalism is shifting its notion of visual evidence from photojournalism to journalistic data representations. First, a card sort analysis of news visuals was conducted on two news sites before and after Edward Snowden's document leak in June 2013. The news images remained relatively consistent, relying heavily on accessible official and stock photography sources. Second, a review of The Guardian's contemporaneous “NSA Files: Decoded” multimedia package found personalized, data-rich visual storytelling techniques. Between the two approaches is a vast difference in how surveillance is represented and made accessible, with implications for the visual coverage of other challenging news topics. 相似文献

OBJECTIVES: The objectives were to examine the effectiveness of a curriculum designed to increase bioinformatics competencies of librarians with diverse backgrounds and to identify demographic factors that may affect the learning process. METHODS: Sixteen professional staff participated in a 12-week training course consisting of 5 distinct modules: molecular biology, genetic analysis, biotechnology, research literature, and databases. Participants completed a 120-question pretest and an 88-question posttest designed to evaluate the effectiveness of the training. RESULTS: Training was deemed successful as all participants scored higher on the posttest than the pretest. Data analysis was conducted in relation to participant background. Holding a biology degree did not seem to affect posttest results. Years of experience, however, had an impact on final scores in the databases section, as senior team members had greater difficulty learning the material. DISCUSSION: As the need for specialized information in the area of molecular biology and genetics becomes more central for the effectiveness of organizations, it is crucial for libraries to quickly align with those needs by having a clear vision for increasing the skills and competencies of their staff in this subject area. This paper describes an effective model for learning that was developed and tested by the Eskind Biomedical Library. 相似文献

ABSTRACTThis thematic analysis of 510 news articles – spanning the leftist-rightist ideological spectrum – examines media rhetoric surrounding President Trump’s 27 January 2017 Executive Order (EO) 13769 barring immigrants and refugees from U.S. resettlement. In this article, I examine how both liberal and conservative news media rhetoric reinforce respectability politics that create a hierarchy of victimhood for those affected by the EO. Interrogating U.S. civil society’s discursive construction of the forced migrant, I expose expectations for appropriate roles for these communities seeking asylum, though these roles are often veiled by normative U.S. mythology. As this analysis illustrates, the news media articles’ discursive erasure of Syrian, Iranian, Sudanese, Iraqi, Libyan, Somali, and Yemeni immigrants and refugees elide forced migrant self-representation and neglect the political/historical reasons for fleeing from their nations of origin. 相似文献
