Environmental issues have become important topics in the 21st century. Communication practitioners and scholars struggle with effectively communicating the threat of climate change and other changes to the natural world, partially due to the lack of concern by the general public. We present Protection Motivation Theory as a framework for explaining proenvironmental behavioral intentions among a college sample. Participants (N = 607) responded to an online survey, and the results indicate support for the proposed model, with severity (H1), vulnerability (H2), response efficacy (H3), and self-efficacy (H4) positively predicting proenvironmental behavioral intentions and response costs (H5) negatively predicting intentions. Implications for practitioners and scholars are discussed, and areas of future exploration in this domain are identified. 相似文献

This study examined the combined effect of character and policy coverage about a political candidate in news media on voters’ evaluations and thoughts about the candidate. A 2 (issue coverage: present/absent) × 2 (image coverage: present/absent) between-subject factorial experiment was conducted whereby participants (N = 134) read a version of an editorial article that varied in the coverage of a candidate’s character and policy positions. Results indicated that issue and image coverage, each in isolation, enhanced perceptions of the candidate’s image strength and issue strength. However, issue and image coverage when presented in combination compared to in isolation did not enhance perceptions of the candidate and in some cases hindered perceptions of candidate strength. When both coverage types were present, issue coverage dominated image coverage when participants formed image evaluations, whereas image coverage dominated issue coverage when they formed issue evaluations. Similar findings resulted for issue- and image-relevant thoughts. Implications about the effects of multicoverage political messages are discussed. 相似文献

This research examined how the interaction between a source's facial similarity to message targets and communicated bias affects audience persuadability. We used an evolutionary explanation to hypothesize that biased sources would elicit less favorable attitudes than unbiased sources for dissimilar sources, but that this difference would be absent for similar sources. Predictions were supported by results from a 2 (facial similarity) × 2 (source bias) experiment, in which an unrecognizable percentage of participants' photographs (n = 94) was digitally morphed with a source's face to act as a kinship cue. Further, structural equation modeling demonstrated a direct effect of facial similarity on attitude independent of mediation by source liking and appraisals, providing further evidence that susceptibility to influence from facially similar sources may have evolutionary origins. 相似文献

The questions of whether college student-athletes should be paid and/or allowed to unionize have generated a wide-ranging national debate. Public opinion on these issues is starkly divided along racial lines, with African-Americans dramatically more supportive than non-African-Americans. We posit that the race gap stems from fundamentally distinct mindsets. African-Americans view pay for play and unionization as mechanisms to enhance educational experiences and hence as a form of affirmative action. Non-African-Americans, in contrast, focus on the extent to which they enjoy the consumption value of college athletics. We present results from a nationally representative survey experiment that supports our expectations. We also find that non-African-Americans can be swayed to employ a more race-based lens on these issues, although this re-framing does not diminish the attitudinal race gap. We conclude with a discussion about race, sports and public opinion. 相似文献

This article considers the representation of global events in The Onion, a satirical news publication. Drawing on a content analysis of headlines and news stories, the article offers a set of general conclusions about the publication’s geographical and topical focuses. When considered in aggregate, the headlines offer an implicit critique of the mainstream media and coverage of international events. The idea that The Onion is a critical voice is, however, subject to interrogation. The Onion should be recognized with other satirical outputs as a profit-oriented enterprise, with appeal to key demographics and growing connections to multinational corporations. Yet The Onion’s position is further complexified through its direct engagement with international actors who do not get the joke. 相似文献
