Mémoire à court terme/Mémoire de travail chez l’enfant sourd profond muni d’un implant cochléaire : contribution à la compréhension des difficultés cognitives des enfants sourds

Abstract : The aim of the thesis is to contribute to a better understanding of cognitive difficulties in deaf children with a cochlear implant (CI). Firstly, this thesis presents a comparative analysis of previous research work. Secondly, it presents an original study addressing short-term memory (STM)/working memory (WM) issues, in which the contribution of cued speech (CS) is assessed on memorization performances. To do so, a novel STM/WM task series was developed and used to investigate whether the use of verbal stimuli versus spatial stimuli differentially affects immediate memory processes and to examine whether the presentation of items in an enriched context has a benefit on the immediate memory capacity. The developed tasks were validated on normal-hearing (NH) children (6- and 8-year-old, N=42) and the capacities of CI deaf children(N=14) were compared to those of their NH peers matched for age, sex and reasoning ability. For both groups, the immediate recall proves to be better for visuo-spatial information. Also, CI deaf children appear as memorizing less verbal information. Surprisingly, CS, appears to be ineffective to improve the CI deaf children performances, especially in the verbal modality case; if the analysis of the order of recall of items does not reveal any specific difficulty, the length of the items lists is harmful in the verbal modality. The analysis of the recall errors confirms difficulties in linguistic knowledge. Individual performances of CI deaf children show diverse patterns.
