The Embodied Cognition: Exploratory Study of Automatic and Controlled Processes in Anorexia Nervosa.

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).

Conditions

• Anorexia Nervosa

Interventions

OTHER

TEA + Grober Test + Task 1 + Grober Test

The Test of Everyday Attention (TEA) measures the reaction time of the participant during the occurrence of an expected stimulus. The Grober Test with 16 words to learn and to remember, measures the episodic verbal memory long term. The Task 1 consists of a stimulus that moves on the screen. The response of the patient is done on the keyboard. It is composed on two conditions: one is fast (without conscious), the other consists in assessing words (conscious). It includes food and non-food words.

OTHER

TEA + Grober Test + Task 2 + Grober Test

The TEA measures the reaction time of the participant during the occurrence of an expected stimulus. The Grober Test with 16 words to learn and to remember, measures the episodic verbal memory long term. The Task 2 consists of a stimulus that is fixed on the screen. The response of the patient is done by pushing or pulling a lever. It is composed on two conditions: one is fast (without conscious), the other consists in assessing words (conscious). It includes food and non-food words.

OTHER

TEA + Grober Test + Implicit Task 3 + Grober Test

The TEA measures the reaction time of the participant during the occurrence of an expected stimulus. The Grober Test with 16 words to learn and to remember, measures the episodic verbal memory long term. The Task 3 is a compilation of tasks 1 and 2 to investigate the bidirectional link. The instructions are implicit condition to detect an A in the word ("yes-no" answer).

OTHER

TEA + Grober Test + Explicit Task 3 + Grober Test

The TEA measures the reaction time of the participant during the occurrence of an expected stimulus. The Grober Test with 16 words to learn and to remember, measures the episodic verbal memory long term. The Task 3 is a compilation of tasks 1 and 2 to investigate the bidirectional link. The instructions are explicit condition to judge the emotional value of words ("positive-negative" answer).
