![]() He explains that they can take an advanced course in astrophysics, or molecular biology, or whatever and say, “Wow. at Columbia University in biological mathematics.ĭoman laughs when he talks about his clients who have been able to raise their performance to a level 13 - repeating back 13 items. At 14, this girl’s neurological functioning had developed to the point that she was able to attend a local community college, and at 16, a four-year college. Sequential processing exercises was a major tool in Doman’s efforts toward the activation and normalization of this damaged brain, as it is in all of the programs he gives to his clients. Through diligence and hard work by the parents putting the infant, and then child she became, through the paces of targeted exercises, the child’s brain was able to build new neuronal pathways that compensated for the extreme damage. NORMAL DIGIT SPAN HOW TOThrough a series of assessment tests, Bob was able to understand precisely how this infant’s mind worked (and didn’t work), and specifically how to best impart information to it. The parents contacted Bob when their infant was only a month old. One client he worked with was born with severe brain damage and with an Apgar rating of 1 (the lowest rating of health that a newborn can have). Not to overstate Doman’s success, but in thousands of cases, he has changed cognitive functioning from severe dysfunctionality to normal and superior functioning. He has worked with over 30,000 people running the whole gamut of classifications - from the severely brain injured, to normal and gifted as well. The finding suggests that when you increase digit span, you increase brain functionality on many other levels.ĭoman has been training individuals to have greater digit-span capability for over 30 years. Make note: These children got no extra remedial work in reading or math, yet their test scores showed improvement far beyond a normal expectation of advancement from typical classroom learning. Within an eight-month time period, test scores (as measured by state mandated tests) increased at a level of approximately 2.9 years in reading recognition, 3.0 years in reading comprehension and 1.67 years in math computation. Finally, researcher and clinician Bob Doman decided to train people to increase their ability to do digit span.Ī research study conducted by Doman in 2002 used exercises to help school children in Louisiana to increase their digit span. 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.Even though there is a mountain of research on sequential processing, and its usefulness as a measure of intelligence, for decades no one had thought to bring the research to the next logical level - to actually change peoples’ digit-span level. 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. 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. ![]()
