L’objectif de cette étude pilote était de tester par électroencéphalographie (EEG) une possible modulation du potentiel évoqué auditif précoce N1 lors de la perception audio-haptique de la parole par rapport à une perception auditive seule. Dans ce but, nous avons comparé les réponses électroencéphalographiques de cinq participants obtenues lors de la perception de syllabes selon différentes modalités : auditive, audio-visuelle et audio-haptique. En accord avec de précédentes études, la comparaison des modalités auditive et audio-visuelle montrent une baisse d’amplitude de l’onde N1 lors de la perception audio-visuelle, un résultat suggérant une intégration précoce de ces deux modalités. Des résultats similaires sont observés lors de la comparaison des modalités auditive et audio-haptique pour les électrodes pariétales. De plus, une plus faible latence de l’onde N1 est observée pour la modalité audio-haptique. Pris ensemble, ces résultats suggèrent une intégration précoce des modalités auditive, visuelle et haptique lors de la perception de la parole et soulignent le possible rôle prédictif des informations haptiques dans le décodage et traitement des informations auditives.
