Disfluences dans le discours conversationnel des patients vasculaires gauches et droits : étude comparative

Abstract : The aim of this study is to identify the deficient cognitive process in language production following a stroke in the left and the right hemispheres. We have analyzed and compared the disfluencies and the production span (prosodical discursive unit) in the conversational speech of 6 right damaged brain patients (CLD) and 6 patients affected with aphasia on their left side (CLGA). The type of disfluencies (full breaks, silent breaks, repetitions), 3 their length and their location (intra or extra-periodic) performed by these 2 groups are compared with those of the control group of 6 damaged left brain patients but without aphasia (CLGnA). The results show first that the aphasic CLG performed more full breaks (uh, um) and their hesitations are within sentences, which is evidence of a wording deficiency. Second, CLD subjects mainly performed lengthy and quiet breaks before discursive units. These breaks could be the sign of either a downturn due to cognitive surcharge or of a conceptualization deficiency, a disorder which is not currently well documented. Therefore, analyzing those differences in spontaneous speeches of these 2 groups CLD and CLGA would indicate a double dissociation between the conceptualization and the wording processes suggesting a functional independence and consequently a different anatomical location.
