My research is mainly concerned with social cognition, attribution, stereotyping, and intergroup relations. After my early work on the Black Sheep effect and the Ingroup Overexclusion effect, I mainly developed an interest in stereotyping and more specifically in the formation and preservation of stereotypes as well as their suppression. The basic idea is that people rely on stereotypes not only for cognitive reasons (they face limited resources) but also for motivational reasons (their stereotypes serve their own as well as their group’s image) and social reasons (they believe their stereotypes are shared by their group members). For many years, I studied group perception by examining aspects of homogeneity, entitativity, and essentialism. More recently, I turned to the issue of fundamental dimensions of social perception in the context of what I call the compensation pattern of stereotypes: people who are perceived to be competent also tend to be perceived as not so warm and conversely. Together with several colleagues, I also initiated a program of research on social emotions in which we investigate whether, how, and why people experience emotions not because of events that occur to them personally, but because of events that affect members of groups to which they belong. Another interest of mine is statistics and methods. The research conducted so far focuses on the use of ANCOVA in personality and social research and issues of moderated mediation and mediated moderation.
