Normal mind-reading capacity but higher response confidence in borderline personality disorder patients.

Borderline personality disorder (BPD) is characterized by a pattern of instability in interpersonal relationships. Therefore, the investigation of social cognition is of compelling interest for the understanding of BPD. One important aspect of social cognition is theory of mind (ToM), which describes the ability to understand others' mental states, such as beliefs, desires and intentions. The aim of the present study was to further investigate ToM in BPD patients.
