We tested the hypothesis that quiet eye the final fixation before the initiation of a movement in aiming tasks, is used to scale the movement's parameters. Two groups of 12 participants (N=24) threw darts to targets in the horizontal and vertical axes under conditions of higher (random) or lower (blocked) target variability. Supporting our predictions, random practice and target changes in the vertical axis led to longer quiet eye duration than did blocked practice and target changes in the horizontal axis. Our data suggest that quiet eye is not simply a mediating factor in accuracy, but is responsive to the task's programming demands, being influenced by the necessity to reparameterize the movement from one trial to the next.
我们检验了这样一个假设，即在瞄准任务中开始运动之前的最后一次注视（即“静眼”）被用于调整运动的参数。两组各 12 名参与者（N=24）在目标变异性较高（随机）或较低（固定）的条件下，在水平和垂直轴上投掷飞镖。支持我们预测的是，随机练习和垂直轴上的目标变化导致的静眼持续时间比固定练习和水平轴上的目标变化长。我们的数据表明，静眼不仅仅是准确性的中介因素，而是对任务的编程要求有反应，受到从一次试验到下一次试验重新调整运动的必要性的影响。
