为了研究排球运动员和非运动员（ns=10）同时执行扫视和按键反应时（RT）任务时的干扰效应，两组在单一和双重条件下尽可能快地对外周视觉刺激的起始作出反应。在单一条件下，受试者的反应是扫视或按键运动。在双重条件下，他们的反应同时与扫视眼睛和按键运动。在两组中，双条件下的按键RT长于单条件下的按键RT。然而，量的按键RT延迟是显着小于排球运动员比非运动员。这表明，运动员的命令，以启动手动运动的排球运动员可能较少干扰的并发眼动命令，以启动扫视眼球运动时相比，非运动员。
To investigate the interference effect in volleyball players and nonathletes (ns=10) when they executed both saccadic and key-press reaction time (RT) tasks concurrently, the two groups responded to the onset of peripheral visual stimuli as quickly as possible in single and dual conditions. In the single condition, subjects responded with either saccadic eye or key-press movement. In the dual condition, they responded concurrently with both saccadic eye and key-press movements. In both groups, the key-press RT was longer in the dual condition than in the single condition. However, the amount of key-press RT delay was remarkably smaller for the volleyball players than for nonathletes. This suggests the motor command to initiate manual movement of volleyball players might be less interfered with by a concurrent oculomotor command to initiate saccadic eye movement when compared to that of nonathletes.
