DD is ADHD and SLOW like a slug in school. What is a normal digit span going backwards? I guess I have no idea. Low digit span can indicate ADHD but, particularly in cases where the child struggles with the backwards digits, it is part of the profile of a dysraxic child as well. According to the book, digits forward and digit backwards may involve different cognitive processes, especially in certain clinical groups and that studies show that the performance of dyspraxic youngsters highlights significant weakness in repeating the digits backwards. I am just reading a book called "Understanding Developmental Dyspraxia - A textbook for Students and Professionals" by Madeline Portwood. Well, I started researching DCD/dyspraxia. (And I fear that the jump to ADHD is so easy and will prevent the 'true' problem from being addressed.) Recently, my son was formally diagnosed with Ehlers Danlos and the geneticist said Developmental Coordination Disorder (a/k/a dyspraxia) is very often co-morbid. I believe there is a problem, but I just simply do not see adhd in him. I really do not feel in my gut like my son has ADHD. I searched high and low for reasons for this and all I ever heard was it is a sign of ADHD. Why? Because he was almost incapable of doing the digit span backwards. However, his overall digit span score was still quite low. When I looked more closely at his scores, it was clear that the forward digit span was fine the first time he tested and quite high the second time he tested (first time on WISC, second time a year later with SB-V). My son had/has an exceeding low digit span score. From this study we found that hearing loss, age have negative correlation with scoring of DST in both of these modalities.Just wanted to add some new (to me anyway!) information regarding low digit span to this thread for those researching. After completing the DST, we continue pure tone audiometry test to find out the relationship between age, hearing abilities with working memory.
#Backward digit span subtest software#
DST in both audio-visual modalities was carried out using software in video format. Procedure and Result: Digit span test was carried out in audio only modalities by using audiometer in a sound treated chamber. Aim of the study: The main aim is to evaluate the possible factors affecting the result of digit span test. The maximum score in each sub test will be 16. The item score is the sum of the score in two trials.
#Backward digit span subtest trial#
For each trial in forward and backward digit span test, a correct response will score as 1 and incorrect score will be marked as 0. The length of digit increases in each line. In this test the examiner asked the participant to repeat increasing span of digit in forward manner for digit span forward test and in reverse manner for backward test. One is digit forward test and another is digit back word test. Wechsler’s Digit span test consist of two subtests. Digit span test is one of the easily accessible tests to detect WM. There are a lot of tests available to determine working memory capacity. Despite physical absence of sensory input, a representation of the information can be maintained over a period of time (Baddely, 2012). WM serves as an interface between perception, long term memory and action. The working memory capacity is limited and it performs both the functions of memory and processing for a short duration of time (Baddeley, 2012). WM refers to a brain system that provides temporary storage for complex cognitive task. Working memory (WM) is the process of keeping information for a short period of time.
