The auditory and visual-spatial WM were assessed by primary test, which included computerized Wechsler numerical forward and backward sub- tests, and secondary tests, which contained three parts: dual visual-spatial test, auditory test, and a one-syllable word recalling test.</p> <p dir="ltr" style="text-align: justify;"><strong>Results:</strong> The results showed significant differnces between working memory capacity in the intellectually disabled children and normal ones (P-value<0.00001). After using the computerized working memory training, Visual-spatial WM, auditory WM, and speaking were improved in the trained group. The mentioned four tests showed significant differences between pre-test and post-test. The trained group showed more improvements in forward tasks. The trained participant&rsquo;s processing speed increased with training.</p> <p dir="ltr" style="text-align: justify;"><strong>Discussion:</strong> According to the results, comprehensive human-computer interfaces and the aplication of computer in children training, especially in traing of intellectual disabled children with impairements in visual and auditory perceptions, could be more effective and vaulable.</p> Working memory training, Computer based rehabilitation, Mild intellectual disability, Designed computerized program 68 73 http://irj.uswr.ac.ir/browse.php?a_code=A-10-458-1&slc_lang=en&sid=1 Mona Delavarian mona.delavarian@gmail.com Yes Department of Psychology and Education, University of Tehran, Tehran, Iran.
