Reality-monitoring & Stress
Sponsor: Hôpital le Vinatier
Summary
Reality-monitoring is a crucial cognitive process in daily life to remember the source of an information. Deficits of reality-monitoring have been shown into the continuum of schizophrenia, suggesting a preexisting alteration in population at-risk for psychosis that will be exacerbated during psychotic transition. It is admitted that stress plays a crucial role in the psychotic transition and can alter cognitive performances. However, less is known about the effects of stress on reality-monitoring, even though this process appears to be central in psychotic disorders. The aim of this project is to investigate the effect of stress on reality-monitoring, both on behavioral and neurophysiological aspects
