The goal of this exploratory, interventional, multicentre study is to compare the prefrontal activity during a negative emotion regulation task in women with Binge-Eating Disorder (BED) and healthy women with and without Emotional Eating (EE). The aim of this study is to compare the prefrontal processing of cognitive control of emotions between BED and EE and to compare the emotional processing and emotional experience between BED and EE. The study will thus compare four experimental groups: patients with BED, BMI-matched healthy volunteers with EE, BMI-matched healthy volunteers, and healthy volunteers of normal weight without BED. Participants will perform a down-regulation task of negative emotions elicited by negative pictures. During this task, their cerebral activity will be recorded using functional near-infrared spectroscopy (fNIRS), as well as their autonomous activity (skin conductance, pulse rate, respiration rate).
