Designing effective corporate social advocacy campaigns using valence,arousal, and issue salience

Corporate social advocacy (CSA) is a growing communications practice that involves corporations taking a public stance on a controversial social issue. Some CSA campaigns have failed in the past (e.g., Pepsi’s 2017 Live for Now Moments Anthem video) by generating public backlash and damaging corporate reputation. To test how to design CSA campaigns that are beneficial for both the corporation and the advocacy issue, the current between-subjects experiment (N = 508) employed a 2 (issue salience: moderate vs. high) X 2 (valence: negative vs. positive) X 2 (arousal: moderate vs. high) factorial design to test the effects of salience, valence, and arousal on memory and four persuasion outcomes: company attitudes, purchase intentions, political participation intentions, and social media intentions, while also analyzing the mediation of information processing. Findings support prior research suggesting that negative valence increases persuasion in CSA contexts. A high-salience issue and high-arousal language increased political participation and social media intentions but had no effect on company attitudes or purchase intentions. Practical implications for CSA campaign designers highlight the persuasive potential of negative valence in CSA messages, and the utility of high-salience and high-arousal for political action and social media engagement.     

Weighting the transitivity of undirected weighted social networks with triadic edge dissimilarity scores

When an individual is socially connected to two others, the resulting triplet can be closed (if the two social partners are themselves connected) or open (if they are not connected). The proportion of closed triplets, referred to as the binary network transitivity, is a classic measure of the level of interconnectedness of a social network. However, in any given triplet, if the closing link is weak, or indeed if any of the links in the triplet is weak, then the triplet should not contribute as much to network transitivity as if all three links were equally strong. I propose two ways to weight the contribution of each triplet according to the dissimilarity between the three links in the triplet. Empirically, the resulting new metrics conveyed information not picked up by any other network-level metric. I envision that this approach could prove useful in studies of triadic mechanisms, i.e., situations where pre-existing social ties influence the interactions with third parties. These metrics could also serve as repeatable synthetic variables that summarize information about the variability of the strength of social connections.     

A means to an end: Using political satire to go viral

With the rise of video sharing giants like Youtube and Google Video, coupled with increased broadband connectivity and improved sharing functionality across social networking sites, the role of the viral video has been cemented in many IMC strategies. While most agree about the importance of better understanding viral marketing, there is less agreement about what makes content become viral. While some content gets viewed by millions of people, others struggle to gain viral traction. Content specific, intrapersonal and interpersonal reasons have been proposed for viral marketing success. This paper focuses on the intrapersonal reasons for content going viral in the context of political satire. More specifically, the role of emotion in the spread of content online, is investigated. Political satire focuses on gaining entertainment from politics. Satire, and specifically political satire, forms part of using humour in advertising and has been influential in shifting public opinion since ancient Greece. This study compares success and unsuccessful viral campaigns that used political satire, by first analysing the online comments that viewers made about the video. Following these findings, an experiment is conducted and the influence of intensity, creativity, humour and utility on virality is modelled, controlling for valence and previous exposure. The findings suggest that, when using political satire in viral campaigns, creativity and the intensity of the emotions felt are key influencing factors in whether videos get “shared” or “liked”. Therefore, while many authors contend that particular emotions or positive content has a greater likelihood to become viral, this paper shows that it is not the particular emotion, but the intensity with which that emotion was felt that drives viral success.     

Testing the qualitative differences between empathy and personal distress: Measuring core affect and self-orientation

In two studies the emotional valence, the level of arousal and self-orientation of empathic concern and personal distress are tested. The empathic concern prevalence versus personal distress prevalence is induced through pictures in Study 1 (N = 62) and perspective-taking instructions in Study 2 (N = 60). Results of Study 1 show that participants in the personal distress-prevalence condition report significantly more negative emotional valence (d = .65), higher arousal (d = .48), and higher self-orientation (d = .57) than participants in the empathic concern-prevalence condition. Results of Study 2 show that participants in the self-oriented condition report the highest arousal, followed by participants in the other-oriented condition, and the objective condition (η_p² = .58). Concerning the increase of self-orientation, results show that it is mediated by the personal distress induced by self-perspective instructions. Similar results in emotional valence were found between self- and other-oriented conditions.
