Abstract EN:
Visual habituation is often considered as linked to information processing, but very few studies have emphasized the relations. Our work has tried to define the relations between visual habituation and information processing. At the end of our experiments, it clearly appears that informaiton processing is achieved before habituation is reached. Habituation can then be considered as involving two successive operations, the first during which information is encoded and a representation made, the second one during which the perceptive imput is compared with the preceeding mnemonic trace, and information recognized as the same. Habituation shows the sam two operations at 3 and 5 months.
Abstract FR:
L'habituation visuelle est consideree comme liee au traitement de l'information visuelle, mais peu d'etudes ont ete menees pour explorer ces liens. Notre travail s'est attache a definir les relations entre le deroulement de l'habituation visuelle et l'avancement du traitement de l'information. A l'issue de nos etudes, il apparait que le traitement de l'information visuelle est termine avant que l'habituation ne soit atteinte. L'habituation peut alors etre consideree comme la succession de deux etapes, la premiere pendant laquelle l'information est encodee et une representation formee, la seconde pendant laquelle l'input perceptif est compare a la trace precedemment formee et l'information reconnue comme identique. L'habituation montre les memes etapes a 3 et 5 mois.
