Clinical Trial Summary

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.


Clinical Trial Description

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. ;
