Brief Summary

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.
