Intégration de sources multiples d'information dans l'identification lexicale et l'acquisition de nouvelles représentations lexicales

This study investigates how French listeners exploi t phonological and phonetic cues in segmenting contin uous speech into words. We examined how these listeners integrate multiple sources of information not only in lexical identification, using the word spotting tas k, but also in the storage of new lexical representations, using an artificial language learning task. Results showed t hat the specific segmentation cues examined had different weights in these two tasks. Syllable onsets, simult aneously cued by allophonic variations and phonotactics, pla yed a predominant role in lexical identification while st ress was a “last-resort” segmentation cue. In contrast, rhyt hmic information, particularly primary stress, played a greater role in lexical acquisition while syllable onsets w ere not used as segmentation cues. These results suggest th at caution is required in relating results on lexical acquisition and lexical identificatio
