Maintaining information in Short-Term Memory between 2 and 6 years old of age : temporal forgetting and helping in maintaining the goal
2014
Working memory is an essential component of thought that is highly involved in learning and academic achievement. However, it is rarely studied in preschoolers, mainly because of a lack of suitable paradigms. Therefore, this thesis investigated the functioning of working memory in children between 2 and 6 years. For this purpose, two original paradigms were used. They were designed to be close to game situations which should help young children to focus their attention on the task. Firstly it was shown that the recall performance decreased over time, even in the absence of an interfering task. Children of this age therefore use a passive maintenance, i.e. without spontaneously implementing …
The mechanisms for maintenance of verbal information in working memory
2011
Working memory is a system that allows to maintain information, while performing a concurrent processing. The subvocal rehearsal (Baddeley, 1986) and the attentional refreshing (Barrouillet et al., 2007) are two mechanisms identified as playing a role in maintenance of verbal information within working memory. However, the exact nature of the interplay of these two mechanisms was little studied and remains unclear. Therefore, the purpose of our work was first to investigate the interplay of rehearsal and refreshing. In several experiments performed with young adults, the use of rehearsal and refreshing were respectively manipulated through articulatory suppression and attentional demand of …
L’utilisation des mécanismes de maintien de l’information verbale en mémoire de travail chez l’enfant de 8 ans
2010
La mémoire de travail est une forme de mémoire immédiate qui permet de retenir des informations tout en effectuant simultanément un traitement sur ces informations ou sur d’autres informations. Elle est indispensable dans la vie quotidienne, par exemple sans elle nous serions incapable de comprendre une phrase ou de résoudre une opération. Les informations stockées dans cette mémoire ne peuvent être maintenues que pendant un très bref instant (± 2 secondes). Cependant, il est possible de les retenir pendant une plus longue durée en utilisant des mécanismes de maintien. Actuellement deux mécanismes de maintien ont été mis en évidence. Le premier est un mécanisme de répétition subvocale, qui …
