Deficits in social cognition and metacognition in schizophrenics makes it difficult for them to understand the speech, facial expressions and hence emotion and intention of others, as well as allowing little insight into their own mental state. These deficits are associated with poor social skills, fewer social relationships, and are predictive of poorer performance in a work setting. reviews recent research advances focusing on the precise nature of these deficits, when and how they manifest themselves, what their effect is on the course of schizophrenia, and how each can be treated. These deficits may themselves be why schizophrenia is so difficult to resolve; by focusing on the deficits, recovery may be quicker and long lasting. This book discusses such deficits in early onset, first episode, and prolonged schizophrenia; how the deficits relate to each other and to other forms of psychopathology; how the deficits affect social, psychological, and vocational functioning; and how best to treat the deficits in either individual or group settings.
