Condition(s) studied

Investigational drug(s) / intervention(s)

Double mirror device ALTER-EGO: The patient and his matched healthy volunteer will be placed on each side of the double mirror device ALTER-EGO. Both sides will be lightened alternatively or at the same time by lights, so according to the light intensity, the subject will see himself in a mirror or the other person throw a classic window. The light intensity will vary from 0 to 100% and to 100% to 0% alternatively from each side of the mirror. At each 10% variation of one side, both patient and volunteer will have to answer that question : "who do you see more : him/her or yourself ?"

EASE test: The patient will have to answer the EASE test which is a specific test to detect patient with high risk of psychosis or schizophrenia
