Introduction: ln literature review, cognitive problems such as poor working memory is considered as one of the main reading problems among dyslexic children. Therefore, the present study was conducted to determine the effect of Reading Assistant Package training on the working memory of dyslexic children.

Visual analyses and the results of the inter-positional and intra-positional analysis showed a significant difference between baseline and intervention stage for all subjects (PND = 100). The persistence of the effect of the Reading Assistant Package on the working memory of the subjects in the follow-up stage was confirmed. Conclusions: According to the findings of this study, the Reading Assistant Package training affects the improvement of the dyslexic childrens’ working memory.
