Ressources attentionnelles mobilisées lors d’une double tâche chez le patient aphasique

Abstract : Several studies have shown that lexical processes require attentional control. More recently, studies conducted on aphasic and control subjects have also underlined the role of attention in post-lexical processes. The aim of this study was to analyze the different steps for word planning during a dual task, more specifically a naming task performed simultaneously to an auditive syllable recognition task. Eighteen aphasic participants were included. Auditive distractors were four different syllables played at three Stimulus Onset Asynchrony (interval between the perceived image and the syllable, i.e. +150 ms, +300 ms or +450 ms). They were asked to name the images as fast as possible, while pressing on a button when they detected a target syllable (active dual task) or ignoring the heard syllables while naming the images (passive task). The results reveal an effect of the dual task on the number of errors in the naming task, with more errors during the active dual task and a significant effect of the dual task on the response time, with an increased response time during the active task observed on the three different SOA times. Finally, there are more semantic paraphasias at 150 ms and more phonological paraphasias at 300 and 450 ms. Our results confirm the implication of attention on pre- and post-lexical processes recruited during a naming task.
