Introduction: Although vision is the dominant sensory system in sports, many situations require multisensory integration. It is noteworthy that the effect of auditory stimuli with visual stimuli in athletes has not been comprehensively investigated. Therefore, the present study aimed to investigate the effect of unisensory and multisensory information processing on decision-making under pressure.Methods: The study was conducted as a quasi-experimental design with a statistical population of elite male badminton players. Thirteen of them were selected by simple random sampling. The players were required to respond correctly in a badminton spatial decision-making task under four conditions (visual stimulus, auditory stimulus, congruent visual-auditory stimulus, and incongruent visual-auditory stimulus) in two normal and under-pressure conditions. PsychoPy software was used to design the task and assess decision-making accuracy, and for statistical analysis, repeated measures variance (2×4) was used at a significance level of 0.05.Results: The results indicated that the decision-making accuracy of elite badminton players in the congruent visual-auditory condition (multisensory) was significantly better than the unisensory visual and auditory conditions separately, especially under pressure. Additionally, decision-making accuracy in the incongruent visual-auditory condition was significantly lower than in the other three conditions.Conclusion: It can be concluded that multisensory integration (visual-auditory) enhances decision-making accuracy in elite badminton players more than unisensory processing (either visual or auditory), which can be explained based on information processing theory. The results also showed that decision-making in all four sensory conditions under pressure was better than in normal conditions, which can be attributed to the high level of experience and skill of athletes in pressure conditions.

Autism is one of the major developmental disabilities which make visual imbalance for those who are vulnerable. Research has shown that vision has a key role in all those activities which focus on aiming task. The aim of this study was to investigate the visual focus on improvement of a throwing task of autistic children. 24 boys at the age of 10 were randomly assigned into two experimental and control groups. Independent t-test and ANVA were used to analyze the data. The results suggested that there was a significant difference between pretest scores in acquisition (p≤0.05). On the other hand, the in experimental group had a better performance in retention phase. . The results suggested that there was a significant difference between pretest scores in acquisition (p≤0.05). On the other hand, the experimental group had a better performance in retention phase. It was concluded that visual affects the throwing task.

the purpose of this research was the effect of visual concurrent feedback on balance ability in 7-13 years old girls. Hence, for this purpose, thirty-four girls student (ranging 7-12 years old) were participated in this study. The students were divided to three group randomly, control, closed eyes and mirror visual concurrent feedback groups, after stork balance test pre-test. Then, groups under interventions completed related trainings. In the present study used paired t-test for comparison of intra-group and one- way ANOVA for inter group (p≤0.05). The result of ANOVA showed that there was no significant difference between pre-test (p≥0/05). But, there was significant improvement in mirror group compared to control group (p=0.001) and closed eyes group (p=0.001). In addition to, the result of paired t-test indicated that only the mirror group has significant progress (p=0.007) in balance and the other groups have significant decrements. Therefore, concurrent feedback in children by use of a mirror to show them self can be improve their balance ability
