Professor at Leiden University

Dr. Jorg Massen

Assistant professor


I am a comparative psychologist specializing in social cognition.  I worked as an Assistant Professor at the Cognitive Psychology Unit of Leiden University (NL). My research mainly focuses on the proximate mechanisms underlying animal social relations, with special interest in cooperative and prosocial behaviours. For that I use both observational and experimental approaches. Moreover, to put my studies in an evolutionary perspective, I employ a broad comparative approach, focusing on a variety of primate and bird species.
