Overview
Brief Summary
Anorexia nervosa (AN) is a common psychiatric illness, with severe prognosis (5% mortality) that has changed little over in half a century. One of the forms is the restrictive anorexia nervosa (ANR). It consists of a phobia of weight gain and food with a massive food restriction. This pathology is studied in psychology but not using the theories of embodied cognition in which "perception and action" interact through sensorimotor processes. They are the source of attitudes (unconscious) towards certain stimuli and influence our interpretation (conscious).
Detailed Description
The investigators hypothesis is that food restriction behavior is the result of two processes. One automatic and not conscious, which is an attraction toward food and manifests itself in the motivational attitudes of approach, and the other controlled and conscious, which prevents attraction to this type of stimuli and is manifested by motivational attitudes avoidance. These processes of attraction and avoidance are observed in embodied cognition paradigms because the answers induce movement of approach or avoidance of stimuli. The validation of these assumptions could lead to reconsideration of the respective roles of automatic and controlled processes in food behaviors of anorexics patients and to complete or refocus psychological techniques of care.
