Judgements and Decisions

 

Central to our research on judgements and decisions is the analysis of perceived contingencies in the social and physical environment. For example, we analyze how biased contingency perceptions, such as illusory correlations and pseudo-contingencies, arise and how they contribute to the formation and maintenance of social stereotypes. Perceived contingencies between social categories can further result from social projection, like the generalization of one's own attributes to other individuals or groups. We therefore investigate cognitive and motivational determinants of social projection in social judgement. In another line of research, we analyze the use of learned contingencies for actual decision making in scenarios in which the distributions of choice options or outcomes are context-dependent.
