My primary areas of research are cognitive styles and social cognition. Especially, I'm interested in hw subtle cues in our environment and cognitive processes influence social judgments. How, for example, does the linguistic syntax of statements or the presentation context affect ratings of truth? How do mindsets, such as an exploratory state or abstract/concrete mindsets, influence time estimations or attractiveness ratings? Additionally, my recent studies investigated the impact of certain concepts (such as money or reminders of one's own death) on cognitive styles, social judgments, and behavior.
