Detailed Description

There are many processes involved in the perception of verbal violence. There is a need for quantified data to have a better understanding the physiological and neurological perception of verbal violence, in order to understand the impact it might have on a subject. This project aims at assessing the influence of time, sleep, and people interaction on the perception of verbal violence. The "cognitive replay" will also be assessed through dreams. The investigators think that sleep plays a role in desensitization to negative emotions and to memory consolidation. However, the role of sleep in verbal violence remains unknown.
