|---|---|
|
Eksperimentel: Patients group 1
Memorization of the verbs by miming the action
|
The participant reads aloud the verbs that appear on the screen, by performing the corresponding action verb.
|
|
Eksperimentel: Patients group 2
Memorization of the verbs by imagining the action
|
The participant reads aloud the verbs that appear on the screen, by imagining the corresponding action verb.
|
|
Eksperimentel: Patients group 3
Memorization of the action verbs by means of another word
|
The participant reads aloud the verbs that appear on the screen.
Then, he reads, without memorizing it, a word associated with the action verb to be learnt to favor the memorization of that one.
The word is written near the action verb.
|
|
Eksperimentel: Patients group 4
Simple memorization of the verbs
|
The participant reads aloud the verbs that appear on the screen, without additional instructions (control condition).

Number of recognized items
Tidsramme: Day 1
|
Participants must recognize TBR verbs among several verbs (distractor or TBF verbs) on the screen.The experimenter notes the recognized verbs. The recognition of a verb in the TBF list or a distractor is considered like an error. |
Day 1
