Making Increase in Bimanual Coordination Task Accuracy under Limitation of Peripheral Vision

Introduction: The effect of central vision occlusion on two-hand coordination tasks is assessed in previous studies. However, the effect of peripheral vision on these tasks is not clearly identified; therefore, the purpose of this study was to investigate the effect of limitation of peripheral vision on two-hand coordination tasks.Materials and Methods: Seven right-handed and right eye-dominant girl students with a mean age of ۲۴.۰۰ ± ۳.۴۶ years participated in this study. Subjects tested under four experimental conditions including peripheral vision limitation of the position of right hand, left hand, and both hands, and no peripheral limitations of hand position in the two-handed Vienna coordination task with four tries for each condition. The data were analyzed using ۱ × ۴ repeated measures ANOVA.Results: All three conditions of visual peripheral limitation showed less errors than the conditions without visual limitation (P < ۰.۰۵). However, no significant difference was observed in the variable of total time between four experimental conditions (P > ۰.۰۵).Conclusion: It seems that the visual peripheral limitation, as an environmental constraint, may increase the focus of individuals in the two-hand coordination task.
