Orientation sélective de l'attention et apprentissage perceptuel (Selective orientation of attention and perceptual learning) [in French]

________________________________________________________________________________________________________ Selective orientation of attention and perceptual learning In this experiment we explored the effect of the orientation of attention on speech processing in a categorization task. We oriented the subjects’ attention by providing information about the cues that were relevant for classifying the sounds and by giving feedback after each response. Our results tended to show a modified behavior when categorizing at the end of this 15-minute experiment. The feedback strongly contributed to these results confirming its prominent role in perceptual learning. The instructions also seemed to have a differential effect on performance. These exploratory data suggest that it is possible to influence subjects’ behavior by selectively orienting attention. Future research is needed to corroborate these results and to uncover the processes involved in perceptual learning. MOTS-CLES : apprentissage perceptuel, catégorisation, attention sélective
