Not Applicable

Completed

• Conditions: Anorexia Nervosa
• Interventions: Other: Joint perception task; Behavioral: Body Shape Questionnaire; Other: Measure of the heart rate

• Registration Number: NCT01964456
• Lead Sponsor: Centre Hospitalier St Anne

Brief Summary

The purpose of this study is to demonstrate that bodily self-consciousness is subjectively and inter-subjectively constituted and that some dimensions of the bodily self-consciousness are impaired in Anorexia nervosa.

Detailed Description

Anorexia nervosa is a severe psychiatric disorder, with high level of mortality. Anorexic patients often experience a serious disturbance in body and their own shape perception.

We hypothesize that bodily self-consciousness is co-constituted by four subjective dimensions which are all inter-subjectively open: in encountering others, one's body is experienced as

1. objectified,

2. the bearer of inter-subjective feelings,

3. an inter-subjective agent and

4. the anchor of an inter-subjectively negotiated perspective.

Across several experiments, we sought to determine which dimension of bodily self-consciousness is altered in Anorexia Nervosa compared to healthy subjects.
