Abstract This study investigated the structure of short-term and working memory in a sample of North American children between 5 and 9 years of age. The Automated Working Memory Assessment (AWMA) is a standardized test normed on a UK sample containing several tasks measuring short- term and working memory across both the verbal and visuospatial domains. A group of 178 school age Canadian children completed the 12 subtests of the AWMA. A three-factor model of working memory was supported. Performance on the different tasks was compared with the normative sample and while the same pattern of results was found, the North American sample’s performance on several tasks was higher. The findings are consistent with a model of working memory characterized by domain-specific storage and domain-general processing components. Cultural differences were noted for the short-term but not working memory measures.

Cette étude a exploré la structure de la mémoire à court terme et de la mémoire de travail dans un échantillon d’enfants nord-américains de 5 à 9 ans. L’Automated Working Memory Assessment (AWMA) est un test standardisé normé sur un échantillon du Royaume-Uni contenant plusieurs tâches verbales et visuospatiales de la mémoire à court terme et de la mémoire de travail. Un groupe de 178 enfants canadiens d’âge scolaire a complété les 12 sous-tests de l’AWMA. Un modèle à trois facteurs de la mémoire de travail était supporté. La performance sur les différentes tâches a été comparée à l’échantillon normatif. Bien qu’on ait trouvé les mêmes schémas de résultats, la performance de l’échantillon nord-américain dans plusieurs tâches a été plus élevée. Les conclusions sont conformes à un modèle de mémoire de travail caractérisé par des composantes d’entreposage selon un domaine spécifique et un traitement selon un domaine général. Des différences culturelles ont été notées pour les mesures de mémoire à court terme, mais pas pour celles de mémoire de travail.
