Research suggests that symptoms, neurocognition and social cognition (SC) influence each other and are related to psychosocial functioning. Both neurocognitive (especially in verbal memory) and SC impairments could have greater responsibility than clinical symptoms on social functioning in schizophrenia. Different biases of cognitive reasoning, such as "jumping to conclusions", contribute both to the formation and maintenance of symptoms and to the functioning in daily life. Cognitive rehabilitation has demonstrated its usefulness in improving cognition, symptoms, and daily life skills in people with psychosis through its effects on brain neuroplasticity. Different programs, such as Metacognitive Training (MCT), appear as promising interventions to improve the typical reasoning biases involved in psychotic disorders. Neurocognition, social cognition and certain reasoning biases interrelate to predict social functioning in schizophrenia. Different psychosocial interventions could improve these processes through their effects on brain neuroplasticity. However, despite the growing body of research, the results are far from being definitive.

Keywords : schizophrenia; social cognition; metacognition; cognitive biases; social functioning; cognitive rehabilitation; metacognitive training.
