My main research interests lie in the area of social cognitive development. Most of my work focusses on counterfactual reasoning (i.e., what children conclude, if past events had not occurred the way they did) and how this is related to the development of complex emotions (e.g. regret, relief) and theory of mind. More recently I have started to investigate how perceived goals influence imitation. I am also interested in children's cooperation as well as in how perspective taking abilities affect children's cognitive and emotional development.
