Source-monitoring & Psychosis

Ninety participants will be included in the study: 30 UHR, 30 FEP and 30 healthy controls. All the participants will complete a standardized source-monitoring task, an MRI acquisition (3D-T1 anatomical scan), a tone-matching task as well as a socio-demographic and clinical evaluation including an assessment of the social functioning.

Source-monitoring Processes and Risk for Psychosis

Source-monitoring is a cognitive process that refers to the ability to remember the source of an information. Some studies have showed source-monitoring deficits in patients with schizophrenia as well as in individuals at ultra-high risk for psychosis (UHR) and in first-episode psychosis patients (FEP). Source-monitoring deficits have thus been proposed as a potential early risk factor for psychosis. However, further studies are needed to better characterize this deficit. The aim of this project is to investigate source-monitoring performances in UHR, FEP patients and healthy controls (HC) and to characterize these deficits in terms of brain anatomy, basic auditory processes and social functioning.
