This pattern was similar for different SLD profiles with clinical diagnoses of dyslexia and mixed disorder, but the impairments were more severe in the latter. Abstract A number of studies has suggested that aging is characterized by a decline in the central executive while the automatic processes (in particular operations by the phonological loop) remain intact. Digit span backwards might be easier than digit span forwards in that format. Despite a GAI within normal range, children with SLD had difficulty with both digit span tasks, but more so for forward span. For instance, Rudel and Denckla ( 1974) found that forward digit span was significantly lower for patients with damage to the left hemisphere compared to a control group, while backward digit span was significantly lower for patients with brain injury to the right hemisphere, associated with the visuospatial code, than for the control group. The correlation of the two spans with a General Ability Index (GAI) was similar in SLD, and smaller in magnitude than in typically developing children. Our results further support the hypothesis that the intellectual difficulties of children with SLD involve working memory in the forward digit span task to a greater extent than in the backward digit span task. This study examined performance in the forward and backward digit span task of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) in a large group of children with specific learning disorder (SLD) as compared with a group of typically developing children matched for age and sex. ![]()
