Perception de la Langue française Parlée Complétée (LPC) et effet d'expertise chez les normo-entendants (French Cued Speech perception and expertise effect in hearing people) [in French]

________________________________________________________________________________________________________ French Cued Speech perception and expertise effect in hearing people Since French Cued Speech (CS) is multi-signal (lip movements and CS gestures), we conducted an eye tracking study to examine whether this perception involves integrative treatment and how expertise affects it in normally-hearing participants. Our paradigm consisted in a word/pseudowords (presented in video clip, without sound) identification task. It included three conditions: a CS condition, a meaningless gesture condition, and a lipreading condition. After each video, participants were presented three options (i.e. correct answer, labial distractor and manual distractor) and instructed to select the correct one. Behavioral and eye tracking data were collected on three groups of normally-hearing partcipants: experts in CS, beginners in CS, and completely naïve toward CS. The first results, very promising, suggest that only experts and beginners integrate CS gestural and labial information, and that the relative weight of labial and manual information seems to change with expertise.
