Abstract A study was conducted on 136, normal, French speaking, independent adults in good health. Subjects were between 25 and 85 years of age, had a minimum of 4 years of education, and were divided into nine groups based on education and age. They were administered a naming task comprised of 40 monosyllabic, 40 bisyllabic, and 40 polysyllabic words. An analysis of variance on correct responses revealed significant main effects for age, educational level, and stimulus length (number of syllables). Significant interactions also were found between age groups and stimulus length and between educational level and stimulus length. The results are discussed in terms of a decline in the retrieval of phonological information from the lexicon associated with aging.

Une étude a été menée auprès de 136 adultes autonomes, normaux, francophones, en bonne santé. Les sujets étaient âgés de 25 à 85 ans et comptaient au moins 4 années de scolarité. Ils ont été divisés en neuf groupes fondés sur la scolarité et l'âge. Chacun a reçu une tâche de dénomination comportant 40 mots monosyllabiques, 40 dissyllabiques et 40 polysyllabiques. Une analyse des différences dans le taux de réponse a révélé que l'âge, le niveau de scolarité et la longueur du stimulus (nombre de syllables) ont des effets importants sur l'exactitude des réponses. D'importantes interactions ont également été constatés entre les groupes d'âge et la longueur du stimulus ainsi qu'entre le niveau de scolarité et la longueur du stimulus. Les résultats ont été examinés relativement à la diminution au niveau de l'accès lexical associée au vieillissement.
