Mindfulness and Cognition in Schizophrenia

Mindfulness (innovative and integrative practice in care) allows the individual to adapt his/her behavior (physical and emotional), in a stressful environment, by regulating cardiac activity, especially the parasympathetic system. In schizophrenia, despite the positive effect of treatments on symptoms (delusions and hallucinations), patients have altered markers of the parasympathetic (high frequency, HF) system. The investigator propose a session of Mindfulness Based Stress Reduction (MBSR) for patients suffering from schizophrenia in order to measure the impact on the parasympathetic system (HF), self-awareness (being well in one's body and being aware of their own actions; EASE) and cognition (attention) in relation to the management of conflicts or emotions. The study compare with patients who receive a session of techniques based on the management of emotions and social cognition (cinemotion, Michael's Game and Tom Remed).
