Stephan Winter (PhD, 2012) is an assistant professor of Persuasive Communication.
Interests: Opinion formation and expression in social media, online marketing communication, personalization, online comments and reviews, credibility and information selection, self-presentation.
Research: My research focuses on the dynamics of opinion formation and expression in contemporary media formats. Given the rise of social media as ubiquitous sources of information, I am interested in the questions of how others’ recommendations influence the selection of content, under which conditions user-generated comments strengthen or diminish the persuasive effects of information or marketing campaigns, and which kind of users emerge as opinion leaders in the new media landscape. A current project investigates how the affordances of social networking sites may trigger an impression-motivated mode of information processing in which users are primarily concerned with the social desirability of their attitudes.
