Primacy of Broadcast News: A Mediation Analysis of Recall,Attitudes, and Voting Intentions

This study examines how the order and proportion of scene valence within a television news story influence viewers' processing of political information. The results of the study, based on structural equation modeling and Sobel's mediation analysis, suggest that, in a news story about a political candidate, positive information on the candidate is recalled better if he or she is praised at the beginning of the story and then criticized at the end than if he or she is criticized first and praised later. In addition, there was a strong proportion effect. Stories with a high proportion of positive scenes were more likely to increase the participant's recall of positive information and induce his or her favorable attitudes and voting intentions than those with a low proportion of positive scenes.     

Effects of Frame Repetition Through Cues in the Online Environment

Research has shown that message frames can shape a reader’s subsequent judgments on political issues. In the online news environment, additional cues outside the story may be present that can affect the power of the frame. This online experiment investigates the role of repetitive cues in the framing processes using news editorials and their accompanying recommended headlines that repeat the editorial’s frame. Results suggest that regarding issue-related attitudes and emotions, consistent frame repetition reinforced the effects of the original article when the frame’s relevance to the readers was high but undermined the article’s impact when the relevance was low. Implications for framing studies and online news consumption are discussed.

Public Space: How Shared News Landscapes Close Gaps in Political Engagement

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.

Negative video as structure: Emotion,attention, capacity,and memory

This paper uses a limited capacity information processing theory of television viewing to investigate the effects of graphic negative video at four levels of processing (attention, capacity, encoding, and retrieval) and on two dimensions of emotional experience (arousal and valence). Results indicate that the presence of negative video in news stories increases attention, increases the amount of capacity required to process the message, increases the ability to retrieve the story, facilitates recognition of information presented during the negative video and inhibits recognition for information presented before the negative video. Results also indicate that the introduction of negative video increases the self‐reported negative emotional impact of the story — making it more arousing and more negative.     

Between Silence and Salience: A Multimethod Model to Study Frame Building From a Journalistic Perspective

Research into frame building, which aims to investigate the development of news framing in the journalistic realm, is on the rise. While most frame-building studies focus on the relative contribution of journalists or sources to news frames, this article presents and evaluates an integrated methodological model. The model is based on constructionist premises with the purpose of examining how frames are created as part of the interaction among reporters, editors, and sources. Based on a review of the methodologies used in earlier frame-building studies, we propose an ethnographic four-phase model in which multiple methods are interwoven: newsroom observations, reconstruction interviews, and frame analyses of news products (which illustrate what is made salient) as well as production documents (which also reveal what is silenced). The model is illustrated with two multisited studies in newspaper newsrooms: an interview-based study of the news reports of preselected journalists and an observation-based study for which the news reports to be analyzed were selected based on their salience in newsroom meetings. Through this multimethod model, this paper offers some guidelines for the study of frame building from a journalistic perspective.     

Race and Ethnicity in local Television News: Framing,Story Assignments,and Source Selections

Because local television has become the primary source for news, this study examined race and ethnicity in news stories, story assignments, and source selections. A content analysis of local newscasts found Latinos, Asian Americans, and Native Americans were virtually invisible as anchors, reporters, and subjects in the news. Although African Americans anchored and reported the news in some markets, overall there was segregation in story assignments. Rarely were Latinos, Asian Americans, or Native Americans interviewed as news sources. African Americans were used as news sources more than other racial and ethnic groups when 2 or more people were interviewed.     

Understanding News Story Chains using Information Retrieval and Network Clustering Techniques

Content analysis of news stories is a cornerstone of the communication studies field. However, much research is conducted at the level of individual news articles, despite the fact that news events are frequently presented as “stories” by news outlets: chains of connected articles offering follow up reporting as new facts emerge or covering the same event from different angles. These stories are theoretically highly important; they also create measurement issues for general quantitative studies of news output. Yet, thus far, the field has lacked an efficient method for detecting groups of articles which form stories in a way that enables their analysis. In this work, we present a novel, automated method for identifying news stories from within a corpus of articles, which makes use of techniques drawn from the fields of information retrieval and network analysis. We demonstrate the application of the method to a corpus of almost 40,000 news articles, and show that it can effectively identify valid story chains within the corpus. We use the results to make observations about the prevalence and dynamics of stories within the UK news media, showing that more than 50% of news production takes place within the form of story chains.     

Setting a Non-Agenda: Effects of a Perceived Lack of Problems in Recent News or Twitter

The mere perception that news has given certain problems more coverage can lead the audience to assume that those problems are more important. Given that the news media, at times, obsesses over relatively trivial matters, and given that the audience is increasingly able to filter media exposure, it is worth asking what happens when audience members perceive that recent media coverage has not emphasized any very important problems. In such cases, audience members might assume that any problems facing the nation must not be particularly important. We explicate this attitude of political complacency, test whether perceived media agendas lacking important problems can influence it, and explore whether complacency helps explain political disengagement. We also explore whether these effects generalize beyond news, to new media gatekeepers such as Twitter. Two experiments tested effects of a perceived absence of important problems in recent news or Twitter content. In the case of news, but not Twitter, this increased complacency in both studies. Study 2 added a no-exposure control and found that effects on complacency were driven by the cueing of nonproblem stories, not by the absence of problem story cues. Both studies validated complacency as a predictor of political disengagement.     

Effects of emotional exemplars in responsibility attribution-framed news reports on perception and evaluations of social issues

This study investigated the separate and combined effects of emotion-laded exemplars and responsibility frames on readers' perceptions and evaluations. Two hundred and sixty-nine students participated in an experiment involving a news story that dealt with the social issue of homelessness in South Korea. Six versions of a news story differed in emotion-laden exemplars with textual information (anger-evoking, sympathy-evoking) and responsibility news frames (attribution of responsibility to society, attribution of responsibility to individual, and no frame). This study found that, compared to the responsibility frames, emotion-laden exemplars significantly affected readers' moral evaluations toward the target individuals and their perceptions of the social issue's severity. The results also indicated that the anger-evoking exemplars influenced readers to attribute responsibility of a problem more to the target individuals than the societal system. In contrast, the sympathy-evoking exemplars prompted greater attribution to the societal system than the target individuals. The likelihood of a reader supporting related governmental aid policy was influenced by both emotional exemplars and responsibility news frames. Implications for further research are discussed.     

In Defense of “Mass Communication” and Other Stuff

A consistent news frame that deligitmizes and depicts most social protests as "police vs. protesters" has been identified in studies of news coverage of social movements. This study used an experimental design to examine the extent to which photographs and prior attitudes toward protests and protesters in general contribute to previously identified framing effects of protest news. Results indicated that for the protest issue of interest evaluations of the protest and protesters were more negative when photos depicting higher levels of conflict were shown. The amount of conflict shown in the photos did not affect evaluations of the protest and protesters when the issue was of less interest to participants. Additionally, participants who had more positive prior attitudes toward protesting in general were more likely to identify with the protesters in the stimulus story and to perceive that the protest was more effective than were those with more negative prior attitudes. Findings suggest the need to address possible nuances associated with the visuals alone and to incorporate prior attitudes when examining effects of news coverage of protests.     

Identifying top news stories based on their popularity in the blogosphere

A huge volume of news stories are reported by various news channels, on a daily basis. Subscribing to all the stories and keeping track of the important ones day after day is very time-consuming. This paper proposes several approaches to identify important news stories. To this end, we take advantage of the blogosphere as an information source to evaluate the importance of news stories. Blogs reflect the diverse opinions of bloggers about news stories, and the attention that these stories receive can help estimate the importance of the stories. In this paper, we define the popularity of a news story in the blogosphere as the attention it attracts from users. We measure popularity of the stories in the blogosphere from two viewpoints: content and a timeline. In terms of content, we suggest several approaches to estimate language models for a news story and blog posts, and we evaluate the importance of the story using these language models. Furthermore, we generate a temporal profile of a news story by exploring the timeline of blog posts related to the story, and evaluate its importance based on the temporal profile. We experimentally verify the effectiveness of the proposed approaches for identifying top news stories.

Photographic Depiction of Normative Deviance and Informational Utility as Predictors of Protest News Exposure,Related Perceptions,and Story Comprehension

News stories about protests are often accompanied by footage or photos depicting dramatic or violent acts that occur during the protest, even though such acts may be rare or insignificant. Although the assumption is that visual depiction of normative deviance draws the attention of audience members, thus facilitating learning about the social issue, extant research does not suggest this will always be the case. The current study found that greater informational utility, not photographic depiction of deviance, increased selective exposure to a protest story in a Web news environment. However, when the protesters were depicted as more, rather than less, deviant, participants reported less positive perceptions of the protesters. In turn, less positive perceptions of the protesters were associated with less attention to and, ultimately, lower comprehension of the accompanying news story. Implications for learning about political and social issues in the current news environment are discussed.     

Credibility in Context: How Uncivil Online Commentary Affects News Credibility

In the new media environment, hard news stories are no longer found solely in the “A” section of the paper or on the front page of a news Web site. They are now distributed widely, appearing in contexts as disparate as a partisan blog or your own e-mail inbox, forwarded by a friend. In this study, we investigate how the credibility of a news story is affected by the context in which it appears. Results of an experiment show a news story embedded in an uncivil partisan blog post appears more credible in contrast. Specifically, a blogger's incivility highlights the relative credibility of the newspaper article. We also find that incivility and partisan disagreement in an adjacent blog post produce stronger correlations between ratings of news and blog credibility. These findings suggest that news story credibility is affected by context and that these context effects can have surprising benefits for news organizations. Findings are consistent with predictions of social judgment theory.     

Agenda Setting and Priming Effects Based on Information Presentation: Revisiting Accessibility as a Mechanism Explaining Agenda Setting and Priming

In three experiments, this investigation evaluated the sufficiency of construct accessibility in explaining individual-level agenda setting and priming outcomes. Participants were exposed to an issue presented within a story from a respected news source (e.g., New York Times), a story from an unknown individual's blog, a story from a respected non-news organization (e.g., National Geographic), a crossword puzzle from a respected news source, or a crossword puzzle from an online game website. Story and crossword content was constant across the different sources. Participants responded either to a measure of implicit priming or to the traditional agenda setting question asking what the most important issue in the nation is. Priming effects were robust across presentation context, indicating a successful increase in temporary accessibility. Agenda setting effects were strongest when information came from news than from non-news sources, regardless of whether the issue was presented within a story or crossword. Findings suggest that issue salience in agenda setting is more appropriately conceptualized as perceived importance rather than top-of-mind awareness. News sources uniquely cue this salience beyond the abilities of other respected organizations.     

Mr. Mom in the News: The Relationship Between Stereotypes and Perceptions of Gendered News Stories

This study examined the relationship between women’s stereotypes and their perceptions of gendered news stories, specifically about stay-at-home parenthood. A between-subjects experiment with undergraduate women revealed that participants with stereotypes about women thought a news story about a stay-at-home mother was more typical than one about a stay-at-home father. Additionally, participants with stereotypes about women thought the news stories were low in realism, regardless of the story’s gendered content. Notably, participants who read the news story about a stay-at-home father found it more enjoyable than the story about a stay-at-home mother, regardless of their stereotypes.

Citation Needed

The ability to add hyperlinks to a news story is a key feature of online news. In addition to the—aging—technical novelty, one can wonder what functions hyperlinks perform in news stories. Previous research, as well as my previous examination of meta-journalistic discourses, has shown that one of the alleged functions of links is to display the writer's sources. In that sense, hyperlinks are “journalistic objects of evidence” as they can directly point to the documents, data or discourses used as rough material for a news story. The present paper puts that particular function of hyperlinks to the test. It conducts a content analysis on a sub-sample of the stories published on six Belgian news sites that contain at least one external link, and compares the links with the sources explicitly mentioned in the news story itself. Results highlight that links and the mentions of sources do not overlap completely. Many sources are not reflected in links, and most links do not point to primary sources per se. Other functions of links emerge, such as providing a service or contextual information to the readers. These findings thus question the material nature of “journalistic objects of evidence” and the possibility for journalists to build networks of distributed responsibility with links.
