Résumé :

It is now well acknowledged that the processes of verbal short-term memory (STM) benefit from the availability of rich and easily accessible lexico-phonological long-term representations. Although phonological and orthographic representations are highly interconnected in the language networks of literate persons, the potential support of orthographic knowledge on verbal STM performance remains little explored. Hence, this study aimed to investigate, in 8-year-old children, the influence of orthographic knowledge on the serial recall of auditory five-words lists in which the phonological and orthographic similarity was manipulated. We observed that, in comparison with lists of rhyming words that also shared the same spelling (as in the French, classe, brasse, chasse, etc.), the inter-items orthographic dissimilarity in rhyming lists (as in the French sport, bord, corps, nord, store, all ending with /oR/) assists the recall of item information (i.e., number of items recalled independently of serial position) but not the recall of order information. In addition, the size of this orthographic effect was highly correlated with performance in irregular word reading (a task that is generally viewed as reflecting orthographic processing abilities). These findings suggest that orthographic representations can be quickly activated in serial recall, even when the stimuli are presented in auditory modality. However, orthographic knowledge seems to support the short-term memory for item but not for order information. This influence is also highly dependent on the children’s level of reading and spelling abilities.
