Age differences were also investigated, demonstrating larger span impairment in older children with SLD than in younger.ĭigit span children with specific learning disorder general ability index wechsler intelligence scale for children–fourth edition working memory. We compared FTLs in the backward and forward conditions and between age and gender groups. 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. Despite a GAI within normal range, children with SLD had difficulty with both digit span tasks, but more so for forward span. This is referred to as the visual digit span test and can be administered either forward or backward. 93, based on a coefficient known as stratified coefficient alpha. The digits forward (DF) and backward (DB) tasks, as in the WAIS-III Digit Span subtest (Wechsler, 1997), are widely used in neuropsychological research and. The digit span test can also be given visually by displaying a series of numbers and then asking the person taking the test to verbally state the numbers and then to write them down in the correct order. 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. The Digit Span subscale (Digit Span Forward, Backward, and Sequencing combined composite) internal inconsistency reliability has been reported at. 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. When information is visual or visual-spatial, Steven is able to overcome the challenges he faces with verbal-only input and is able to register and manipulate information as well as his agemates can. 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. significantly better than Digit Span Forward and Spatial Span Backward was significantly better than Digit Span Backward. The nature of the relationship between attention, or memory span, and intelligence has been explored by intelligence and memory researchers alike in the past.
