Description Impairment of social cognition is one of the main features of schizophrenia. This feature is extensively studied in the present day, there are several studies investigating various domains of social cognition and their neurophysiological substrates, as well as its relationship with functional outcome, neurocognition and symptoms. In spite of this, the options for treatment are limited. A number of tests that measure social cognition are available, however there is a lack of standardized battery, that would measure these abilities across domains in time. This is to some extent due to wide array of manifestations, from recognition and discrimi- nations of emotions of others, emotion processing to understanding of intentions and beliefs of others. The borders between areas are not clearly set, the deficit in the domains is consistent thorough the whole course of disorder. The deficit is most prominent during first episode, but can be traced in an attenuated form also in the prodromal phase, and continue to be present during remission. The sings of impaired social cognition were found also in first-degree relatives and individuals with ultra-high risk for psychosis. The social cognitive abilities are not explainable by deficits in neurocognition nor metacognition. In addition, they are related to presence of disorganized and negative symptoms. They are also significantly associated with quality of life and functional outcome, more than neurocognition. Training of social skills and social cognition shows effect of improvement, from moderate in general functional outcome, to high improvement in tests measuring performance in specific social-cognitive domains. Psychopharmacological research to this date has been focused mainly on effects of antipsychotic medication, improvement is however clinically insignificant. The findings summarized in this paper might contribute to better understanding of impairment of social cognition in schizophrenia, and focus the research on the areas that will result in development of more effective treatment methods.
