Validation d’une tâche d’évaluation de la prosodie réceptive après un avc droit

Abstract : Introduction : The adaptation of the “Reverse Correlation” task enables the linguistic prosody perception assessment by accessing the subject’s mental representations of an interrogative intonation. The purpose of this study is to confirm the applicability and the sensibility of the “Reverse Correlation” task to right-hemisphere stroke patients, and to investigate links with other cognitive functions.
Methods : The “Reverse Correlation” task has been submitted to 13 right-hemisphere stroke patients whose stroke happened less than one year ago. Their results were compared with their performance in an auditory test, a depression screening’s scale, and with evaluations of other cognitive functions. The “Reverse Correlation” task has also been submitted to 12 healthy subjects.
Results : The patients’ mental representations of an interrogative intonation are different from healthy subjects’ ones. There are correlations between the “Reverse Correlation” task and depression on one hand, and auditory central processing on the other hand. There is no correlation between the task and auditory perception, music processing, attention in hearing modality, and another evaluation of prosodic perception.
Conclusion : This study suggests that the “Reverse Correlation” task is significant to evaluate linguistic perceptive prosody disorders with right-hemisphere stroke patients.
