Welcome to the lab of Prof. Dr. Mitja Back. My associates, students and I are interested in the interplay of personality and social relationships.

Our research focuses on how personality affects the initiation and maintenance of social relationships and how, in turn, social relationships feed back into the development of social identities.
Latest projects, cover topics such as personality self-knowledge and self-enhancement, the indirect assessment of personality and attraction, the assessment of narcissism and the popularity of narcissists, the accuracy of interpersonal judgments, personality and speed-dating, personality and the development of friendships, behavioral, affective, and cognitive state variability, as well as the development of personality and self-esteem in social context.

In teaching, we provide a comprehensive B.Sc.- and M.Sc.-program in personality psychology and psychological assessment, including lectures and courses on psychodiagnostics, test theory, differential psychology, performance, ability and personality tests, test construction, and psychological examination.
