Whereas the role of social media in political activism has received much attention in recent years, the role of social media images remains largely understudied. Given the potential of emotional and efficacy-related visual content for motivating activism, this exploratory content analysis examined the content of Twitter images of the 2011 Egyptian revolution. The analysis of 581 images revealed more efficacy-eliciting (crowds, protest activities, national and religious symbols) than emotionally arousing (violent) content, especially posted by Egyptian users. However, emotionally arousing content decreased, whereas efficacy-eliciting content increased at times of instability. Furthermore, popularity of images was more associated with user information than the content itself. Images posted by activists and users outside Egypt received the most attention. The findings are discussed in terms of possible explanations for the content patterns and their potential impact on Twitter audience, as well as their contributions toward establishing a theory of user-generated content during political movements.
Emotion is often treated as unconducive to rationality and informed citizenship. For this reason, journalistic styles that personalize issues and elicit emotion are typically not taken seriously as information sources. The experimental study reported here tested these sentiments through the knowledge gap hypothesis. Eight investigative news stories, arguably important to informed citizenship (e.g., child labor, corruption in public housing administration, lethality of legal drugs), were each presented in two versions. One featured emotional testimony of ordinary people who experienced the issue, and the other did not-resembling the traditional view of news as cold hard facts. Emotional versions were associated with smaller knowledge gaps between higher and lower education groups. Moreover, the size of knowledge gaps varied across three memory measures: free recall, cued recall, and recognition. Contrary to the inimical role that is traditionally assigned to emotion, these findings suggest a facilitative role for emotion in informing citizens.
Education-based knowledge gaps are well-documented across countries, media platforms, and content. Without exception, knowledge is measured through words not images. Given the centrality of sight in the natural history of Homo sapiens, the extraordinary visual acuity of humans, and the proliferation of screen-based visual media environments in contemporary life, an experiment was conducted to test the knowledge gap visually. Participants watched 8 audiovisual news stories. Simple recognition of story details and comprehension of that information were tested in verbal and visual modalities. Results offered the first confirmation of the knowledge gap in visual terms. Yet, gaps were significantly smaller employing visual than verbal measures, pointing to the need for continued efforts to develop visual measures for future memory studies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
