Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Source-monitoring is a cognitive process that refers to the ability to remember the source of an information. Source-monitoring processes are usually studied using experimental behavioral tasks. These tasks, which are very heterogeneous, are not all available in French and, for the most part, cannot be used in neuroimaging protocols.

The aim of this project is to develop an experimental task which allows the measurement of source-monitoring performances, and which is adapted to neuroimaging protocols in a French-speaking population.

Intervention Model

PARALLEL

For step 1, two populations of participants: 30 healthy volunteers and 30 patients with schizophrenia will have to complete a verbal material scoring questionnaire. For step 2, two populations of participants: 30 healthy volunteers and 30 patients with schizophrenia will have to complete the source-monitoring task which will be created from step 1 as well as the task of reference (Brunelin et al., 2008).
