The purpose of this study was to investigate the effect of selected programs (including agility, speed, visual and auditory stimulation, mirror training, etc.) on the simple and choice response reaction time of children with developmental coordination disorder. Materials and Methods: In this research, a semi-experimental design with pre-test and post-test design was used for two groups of experimental and control children (DCD). A sample of 30 children (DCD) was selected using random sampling method. A pre-test was performed for both groups, and the speed of visual response, visual choice and auditory simplicity of the groups was measured by a four-way reaction speed measuring instrument. The experimental group was then tested for 12 session by selected exercises. The posttest was performed for both groups of children. The statistical methods included Kolmogorov-Smirnov test, and Covariance test. The results showed that the exercises for 8 weeks significantly improved the visual response rate (P = 0/001, t = -4/30), visual selectivity (p = 0/006, t =- 3/34), simple listening (P =0/.001, t =-5 /19) in the training group compared to the pretest. The results show that there is a significant correlation between the speeds of the children's response to the children (DCD), which is practiced.

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.
