the comparison of the effect of cognitive load on duration and accuracy of bimanual coordination task

in this study, the effect of cognitive load (cl) training on duration and accuracy of bimanual coordination (bc) task was investigated. for this purpose, athletic male students of shiraz university were randomly divided into 4 groups: g1 with low cl, g2 with intermediate cl, g3 with high cl and g4 control. the subjects practiced for 6 weeks, 3 sessions a week, 6 blocks, 12 trials. the subjects performed bimanual coordination task by vienna test system (v=71%-84% and r=85%-96%). independent t test and one-way anova were used to analyze the data. the results showed that high cl affected the accuracy of bimanual coordination task. no significant difference was observed between cl groups and control group in overall duration (?=0.05). it can be concluded that if there is high cl in activities which require much attention, attention capacity may change and in skills that need attention, the task can be improved after information processing as a result of capacity change.
