Social Cognition

Social cognition refers to mental operations underlying social interactions,[64] with one being the ability to infer mental states of others, termed 'mentalization' or Theory of Mind (ToM).[65] There is an expanding literature on social cognition deficits in BPD, albeit with no BP II and BPD comparison studies. Failure of mentalization is a central deficit in BPD,[66,67] characterized by difficulty using the cognitive strategies of reappraisal and suppression to regulate intense emotions.[68] Martino et al.[65] reported lower ToM performance in euthymic BP II individuals relative to controls; however, potential confounders included medication exposure and attention-executive function impairments.
