Résumé

Lorsqu'on présente simultanément l’image d'une personne prononçant la bisyllabe /aga/ et le son /aba/, les participants ont tendance à dire qu'ils ont entendu /ada/. Cette illusion est connue sous le nom d'effet McGurk. La présente étude explore les conséquences perceptives de la séparation spatiale entre les sources visuelle et sonore sur l'effet McGurk. Un signal auditif était présenté a 0, 30, 60, et 90 degrés en azimuth par rapport au signal visuel. Les résultats demontrent que les paramètres spatiaux n'ont que peu d'influence sur l'intégration visuo-auditive des signaux.
