This study was conducted to determine the effect of Nintendo Wii-based motor and cognitive training on executive function of children with attention-deficit/ hyperactivity disorder. Statistical population of this research included boys with ADHD, aged 8-11. Years. 27 eligible participants were selected from Avand development center and were randomly assigned and were randomly assigned to an experimental and control group. The experimental group participated in a selected gaming program for 24 sessions, 60 minutes per session. At the beginning of the study and after eight weeks of intervention, participants were assessed with Corsi-Block-Tapping test, GO/No-Go test and Tower of London (TOL) test. R Statistical software were used for data analysis. The resulting data were analyzed using ANCOVA and MANCOVA. The results showed that working memory and response inhibition in the experimental group were significantly improved in comparison to the control group, in assessing planning, there were significant differences between groups in TOL score that measured correct solved problems. But there were no differences in TOL scores that measure performance of planning time and planning speed (P >0.05).. These results suggest that Nintendo Wii game playing might be a simple and cost effective way for improving executive function of ADHD children.

The purpose of this study was to investigate the effect of a selected training program under dual and single-task conditions on the cognitive flexibility of children with developmental coordination disorder. The research method was semi-experimental and with a pre-test-post-test- follow-up design with control group. The statistical population of this study included male students with developmental disorder in Ahvaz city. From the mentioned population, a sample of 39 subjects who were eligible for inclusion in the study was selected by available sampling method. After the Trail Making Test as a pre-test, they were randomly assigned to three groups: Exercise Dual task (n=13), single task training (n=13) and control (n=13). Then, the two experimental groups performed a selected training program with different conditions for 8 weeks and 3 sessions each 45 minutes each week. At the end, all subjects were followed by a Trail Making Test and two months later, a follow-up test. Data analysis using one-way covariance analysis as well as t-test showed that in post-test, cognitive flexibility in dual task group was superior to both single and control group (P < 0.05). In the follow-up test, this superiority remained only rather than the control group. Also, the single task group was superior to the control group in the post-test (P <0.05). Compared to single-task approaches, dual-task-based exercises can improve the cognitive flexibility of children with developmental coordination disorder, so using this method in the planning of classes is suggested for this group of children.
