我们研究了目标导向瞄准中视觉矫正过程的空间和时间限制，以及在线控制中的性别差异。最初的实验进行测试的效用的单眼开关程序作为一种方法，迅速引入视觉扰动。结果显示，单目开关对运动时间和终点误差的影响很小。在该对照实验之后，在运动开始时和运动期间引入棱柱位移。在第三个实验中，棱镜在运动开始之前出现，然后在运动开始时或运动过程中被移除。运动轨迹的影响最大的早期介绍和删除的棱镜，和女性的表现是显着的影响，这两个扰动比男性的表现。
We examined the spatial and temporal limitations of the visual corrective process in goal-directed aiming, as well as gender differences in online control. An initial experiment was conducted to test the utility of a monocular switch procedure as a method of rapidly introducing a visual perturbation. The results revealed minimal effect of the monocular switch on movement time and the endpoint error. Following this control experiment, prismatic displacement was introduced at the initiation of and during the movement. In the third experiment, the prism was presented prior to movement initiation, and then removed at the beginning of or during the movement. Movement trajectories were most influenced by the early presentation and removal of the prism, and female performance was significantly more affected by both perturbations than male performance.
