الذاكرة العاملة لدى عينة من الأطفال ذوي متلازمة داون : دراسة مقارنة

الملخص EN

Aims: The current study aims at identifying the differences between typically developing (TD) children and children with down syndrome (DS) in working memory, as it plays an essential role in developing the cognitive abilities of DS children.

Sample: The study consists of three groups; the first one includes 10 children with DS with a chronological age of 4 years, the second group has 10 children with DS with a mental age of 4 years, the third group includes 10 TD children.

It was taken into consideration that no one of the participants has any kind of auditory or visual deficits according to their mothers' responses to the initial data form.

Methods: We used two main tools to control the sample; initial data form and colored matrix task.

To measure performance, we used verbal and non verbal working memory measures that represent the fifth picture interface measure.

Results: The results show that there were statistically significant differences between the mean scores of all participants in verbal and non verbal working memory tasks and entire working memory tasks, as DS children with chronological and mental age achieved lower scores than their mental- age matched group of TD.
