朝向一个物体的动作是由关于目标和手臂的视觉信息持续引导的。这样的制导提高了精度，并允许在目标意外移动时调整运动。正在进行的手臂运动也受到周围运动的影响。对周围运动的快速反应可以帮助应对移动的障碍物，以及眼睛方向和有利位置变化的后果。为了进一步评估周围的运动如何影响拦截运动，我们要求受试者在移动目标到达第二个静态目标时轻击它。我们改变了周围运动的方向和位置，以及已知影响眼球运动的刺激的细节。当背景运动靠近目标时，受试者对背景运动最为敏感。无论眼睛是否在运动，以及背景运动的方向与眼睛运动的方向的关系，对背景运动的反应几乎没有影响。我们得出的结论是，背景运动的响应是由目标附近的运动驱动的，而不是由光流及其与其他自运动信息的关系的全局分析驱动的。
Reaching movements towards an object are continuously guided by visual information about the target and the arm. Such guidance increases precision and allows one to adjust the movement if the target unexpectedly moves. On-going arm movements are also influenced by motion in the surrounding. Fast responses to motion in the surrounding could help cope with moving obstacles and with the consequences of changes in one’s eye orientation and vantage point. To further evaluate how motion in the surrounding influences interceptive movements we asked subjects to tap a moving target when it reached a second, static target. We varied the direction and location of motion in the surrounding, as well as details of the stimuli that are known to influence eye movements. Subjects were most sensitive to motion in the background when such motion was near the targets. Whether or not the eyes were moving, and the direction of the background motion in relation to the direction in which the eyes were moving, had very little influence on the response to the background motion. We conclude that the responses to background motion are driven by motion near the target rather than by a global analysis of the optic flow and its relation with other information about self-motion.
