Experimental: Patients group 1
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. |
|
Experimental: Patients group 2
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. |
|
Experimental: Patients group 3
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). |
|
Experimental: Patients group 4
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). |
