The speed of visually triggered movements depends, among other things, on the time needed for visuomotor transformations. We show that it takes on average 20-40 msec less time to respond to visual stimuli when they are projected on the reacting fingers than a few centimeters away from them. The result implies significant preference of the personal space to the extrapersonal space for stimuli used in the initiation of visually triggered movements.
视觉触发运动的速度取决于多种因素，其中包括视动转换所需的时间。我们发现，当视觉刺激投射在反应手指上时，反应时间比离手指几厘米远时平均要快 20-40 毫秒。这一结果表明，在启动视觉触发运动时，个人空间对刺激的偏好明显强于超个人空间。
