[Disturbances of social cognition in schizophrenia].

Social cognition is an ability to perceive socially relevant stimuli and to behave accordingly. It is connected with the processing of information brought about by significant social stimuli. Recently, social cognition is a topic of intensive research in psychology, neurosciences and psychiatry. Processes involved in social cognition include: perception of emotion, input of eye contact, reaction to voice prosody or decision-making in social situations. A particular role is played by the mentalizing capabilities (mind-reading) i.e. ability to interpret behaviour of others by attributing them certain mental states. Such an ability is often conceptualized as the Theory of Mind (ToM). This paper is a review of issues connected with disturbances of social cognition in patients with schizophrenia. Deficits in perceptions of face emotion and disturbances of Theory of Mind function in schizophrenia were discussed with special regard to their potential role as endophenotypes of vulnerability to schizophrenia. Also, relations between social cognition and basic neurocognitive processes were presented, as well as the effect on social cognition of different methods of schizophrenia treatment.
