Examining the impact of various media sources on knowledge has a long tradition in political communication. Although much of the extant research focuses on the impact of traditional media on factual knowledge, research is expanding to include a variety of media sources and multiple dimensions of knowledge, in addition to understanding processes that better explain these relationships. Using a nationwide, opt-in online survey (n = 993), we examine the relationship between partisan media and structural knowledge, which assess how interconnected people see political concepts. Utilizing understanding of the Affordable Care Act as the content area of interest, we examine whether exposure to partisan media has differential effects on attitudinal ambivalence—holding both positive and negative attitudes toward an object—based on the political ideology of the respondent, and whether this impact of ambivalence influenced structural knowledge. Our results show that exposure to attitude-consistent media decreased attitudinal ambivalence. This exposure to attitude-consistent media results in a positive indirect effect on structural knowledge through this decrease in ambivalence. We find the reverse effect for use of attitude-inconsistent media. 相似文献

Binge-watching, simultaneously treated as both guilty pleasure and legitimate health concern in popular press and academic discussions, is a pervasive media behavior. Yet distinguishing it from other ways of television viewing remains elusive in communication research. The present study employs empirically supported variables to determine if different outcome expectancies are relevant to the frequency of binge-watching as contrasted with appointment viewing of television through the lens of the model of media attendance. Survey results (N = 797) of a college student and representative adult sample reveal that binge-watching is motivated in large part by the behavior already being an entrenched habit among viewers, while suspense and anticipation associated with content and motivation to use viewing to regulate one’s emotions are also significant antecedents. Conversely, more frequent appointment viewing of television viewing was driven by viewing efficacy and older age. 相似文献

This study examines credibility perceptions in online consumer reviews. Specifically, this work investigates the effects of review emotionality (high vs. low), review valence (positive vs. negative), and individuals’ need for affect on source credibility and information credibility. In an online experiment, U.S. adults (N = 327) viewed a product review from Amazon.com varied across four experimental conditions. Results indicate that high-emotionality reviews are perceived as lower in source and information credibility compared to low-emotionality reviews. A moderated mediation model was tested with the source credibility dimensions as possible mediators of information credibility and need for affect as a moderator for the effects of review emotionality. The effects of emotionality on information credibility were significantly mediated by source trustworthiness, and this mediation was moderated by participants’ need for affect, with the credibility-hampering effects of emotionality found only among participants with low and moderate levels of need for affect. 相似文献

Research has shown that holding conflicted attitudes (ambivalence) about political decisions may lead people to act as ideal citizens. One example of this normatively ideal behavior is seen in research linking ambivalence to information seeking. To expand on this line of inquiry, this study examines the over-time relationship between ambivalence and information seeking. We use three-wave panel data collected during the 2012 election to determine whether over-time relationships exist between these variables and test the causal direction of these relationships. We find that use of counterattitudinal information increases ambivalence, which leads people to seek out more counterattitudinal information. We also find that use of pro-attitudinal media decreases levels of ambivalence. 相似文献

调研国内通过新浪认证的高校图书馆微博,发现我国高校图书馆微博数量呈现上升趋势,但服务水平参差不齐;高校图书馆微博的粉丝数与博文数、博文更新频率,关注数与博文数之间均呈现显著的正相关关系;在利用微博加强与读者的互动及发布各类新闻、资源信息等方面,各图书馆微博侧重点存在差异;评论和转发量高的博文话题,基本都集中于图书馆新闻、馆内重要通知、讲座展览信息以及美文美图分享、读者互动等方面.该文认为,我国高校图书馆要进一步发挥微博在信息服务中的效用,还应制定图书馆微博管理制度、加大微博的营销宣传力度、增强微博内容的吸引力,并充分发挥微博的互动功能. 相似文献

独立学院图书馆信息资源建设现状调查与分析 总被引：2，自引：0，他引：2
信息资源建设是独立学院图书馆的基本职责和任务。独立学院图书馆的信息资源建设主要包括印刷型馆藏与电子资源馆藏建设、信息资源共享、信息资源的组织与服务等内容。通过对100个独立学院图书馆网页的调查,发现目前独立学院图书馆信息资源建设尚未形成相对完整的馆藏体系、信息资源共享意识较弱、网站建设薄弱。独立学院图书馆应制定清晰、详细的馆藏发展策略,重视与校本部图书馆建立信息资源共享关系,加强图书馆网页建设,以解决信息资源建设存在的问题。 相似文献

目前,大学生在学习或学术研究过程中由于缺乏从大量信息中抽取所需信息的能力,期望获取的信息内容与所获取的信息内容之间存在差距而产生信息焦虑现象,影响了研究进程。帮助用户克服信息焦虑是图书馆与其他信息机构职能的重要分野。对高校学生信息焦虑程度的调查可见,图书馆可以在信息焦虑的五大影响因素的基础上采取图书馆干预理念对参考咨询服务模式进行新的构建,并结合实际情况拓宽信息焦虑咨询平台。 相似文献

The current study tests whether media consumption is associated with negative intergroup emotions toward Blacks, Latinos, and Asians and whether media use indirectly influences intergroup emotions via threat perceptions. We do so using a two-study survey design. Results from Study 1 indicated that media consumption is associated with anger toward Latinos and Asians but not anger toward Blacks. We also found that media use was associated with anxiety toward Blacks, Latinos, and Asians. Results from Study 2 indicated that media use indirectly influences anger and anxiety toward Blacks and Latinos through perceptions of threat. Media consumption did not indirectly influence anger and anxiety toward Asians, though perceptions of threat did directly influence intergroup emotions toward this group. The discussion highlights the important, but negative, role of media in intergroup processes. 相似文献

This investigation explored the relationship between value-relevant (VRI), impression-relevant (IRI), and outcome-relevant involvement (ORI) on information-seeking behaviors, attitudes, and purchase intentions. Results revealed that grocery shoppers' (N = 175) ORI was positively associated with information-seeking behaviors, attitudes, and purchase intentions of foods high in fiber. Neither VRI nor IRI predicted attitudes or purchase intentions. Results are discussed with an emphasis on information seeking among the three types of involvement and message-design strategies with respect to promoting foods high in fiber. 相似文献

Previous research has shown that self-affirmation can reduce individuals’ defensive processing of threatening health messages. In this study, we examine two audience characteristics—smoking experience and trait reactance—that might regulate the effects of self-affirmation on negative message responses within the context of college smoking. Results of a controlled experiment indicate that self-affirmation worked to reduce negative message responses among smokers who were low in trait reactance. For smokers high in trait reactance and nonsmokers, the effect of self-affirmation was either unclear or went in a direction that led to even greater defensive processing. 相似文献
