The aim of this study was to compare the effectiveness of perceptual motor training and cognitive games on cognitive development in mentally retarded children. In this experimental study, 45 mentally retarded children aged between 8 and 12 in Kermanshah province were randomly divided into 3 groups: perceptual motor training, cognitive training and control. The perceptual motor program included the protocol of Salari et al. (2014) and Kashi et al. (2015) and cognitive games included a collection of cognitive games of my brain that was run as software. The groups participated in the program for 8 weeks, 2 sessions per week and 45 minutes per session. Before and after the training, they participated in London Tower computer test and the Stroop color-word test as pretest and posttest. Data were analyzed with Mancova and Ancova tests.The findings of the study showed a significant difference among perceptual motor training, cognitive games and control in London Tower computer test and Stroop color-word test. Perceptual motor training had a greater effect on the improvement of cognitive functions in mentally retarded children than cognitive games. Therefore, it can be concluded that although both types of games play an effective role in improving cognitive development and can be used to improve children's well-being, perceptual motor training is a better tool to create more development effects than cognitive training.

Goal setting is a motivational item that is usually used for enhancing sport skills learning. The aim of the present study was to investigate the effect of easy versus difficult goals on acquisition and retention of basketball free throws in educable children with mental retardation (AWMR). A total of twenty one AWMR educable students (aged between 8 and 13) were assigned to either a difficult or easy goals group. Participants exercised the task for nine sessions across acquisition phase. Both groups performed a pretest before the acquisition sessions. Acquisition tests were taken during acquisition phase, and immediate and delayed retention tests were also taken after 2 and 10 days of no practice respectively. We performed statistical analyses with a repeated measures analysis of variance (ANOVA), and an independent t test. Results showed that easy goal setting group significantly improved their performance in acquisition and retention phases (P<0.05) while difficult goal setting group showed no improvement in their performance. These findings suggest that setting easy goals instead of difficult goals improves the performance of basketball free throws in children with mental retardation

The aim of the present study was to investigate the effect of contextual interference on balance of mentally retarded people. For this purpose, 40 educable and mentally retarded boys in Qazvin city (mean age 24.45 ± 3.120) were randomly divided into two groups: blocked and random practice. After the pretest, given their practice arrangement, subjects in each group performed their workout for 4 weeks (3 sessions per week) as the acquisition phase. Acquisition test was conducted in the last session, and then retention and transfer tests were performed after 48 hours. After Kolmogorov-Smirnov test verified normal data distribution and Leven test examined the homogeneity of variances, analysis of variance with repeated measures showed that the intervention was effective and the groups significantly improved (P=0.0005). The results of the independent t test (to compare two groups in static balance) showed that random practice group performed better in retention test (P=0.007) whereas no significant differences were observed between the groups in transfer test (P=0.061). In addition, dynamic balance results showed that random practice group performed better than the blocked practice group and it had a significant difference in retention and transfer tests (respectively P=0.001, P=0.002). So, mentally retarded people can use the beneficial effects of random practice.

The purpose of this current study was to investigate the influence of perceptual-motor trainings on motor skills of girls with trainable mental retardation. so 20 girls with trainable mental retardation in the town of Marivan welfare organization with the average of 8/3 ±1/11 years and IQ of 39/14±6/84 with purposive sampling method were studied. All girls were pretested. Then samples based on sampling method divided into two 10 groups and considered as the control and experimental groups purposefully .In this research, for assessing the gross and fine motor skills we used sections of Bruininks _ oseretsky test . The experimental group did the perceptual-motor training for 24 sessions of practice, in a week .After 24 sessions of practice both groups were post‒test .In order to study the research hypothesis, nonparametric Wilcoxon and U Mann Whithney test were used. The results of the statistical tests showed significant difference on gross motor skills in training groups (p<0.05). while the impact of this training course on gross skills was not significant statistically. The findings showed that training program used in this current research is to improve the gross motor skills in girls with trainable mental retardation and can be useful

The main purpose of the present study was to investigate the effect of different combinations of music and rhythmic movements on behavioral problems of children with mild mental retardation. A total of 40 children with mild mental retardation were randomly divided into 4 variations of practice including: rhythmic movement with major scale music, rhythmic movement with minor scale music, rhythmic movement with no music, and no rhythmic movement-no music (control group). Rutter inventory (Parent version) was used to evaluate behavioral problems. Pretest was taken before the intervention and post-test was taken after 12 weeks of practice (36 sessions). For data analysis, one-way analysis of variance and Tuki follow up tests were used. Results showed that behavioral problems of rhythmic movement with major scale music group were significantly decreased. It was also shown that the rhythmic movement with minor scale music and rhythmic movement with no music showed no significant decrease on behavioral problems of mentally retarded children. No considerable change was found in behavioral problems of the participants of the control group.

The Purpose of this study was to compare the effects of different combinations of mental and physical practices on the acquisition and retention of a motor skill in mentally retarded male students. Subjects were 40 guidance students who were healthy and novice in basketball penalty shot. They were selected randomly and were assigned to 5 homogeneous groups (4 as experimental and 1 as control) based on their pretest scores, IQ and their ability in mental imagery. They exercised for 8 weeks, 3 sessions per week. Kolmogorov-Smirnov test, paired T test, one-way ANOVA and Tukey post hoc test were used to analyze the data. It was observed that all four variations of practice improved their performance, yet the mental practice followed by physical practice group outperformed the other groups. The results suggest that mental practice followed by physical practice results in an outstanding performance in mentally retarded adolescents.
