大量的证据表明，人类和动物观察者对向他们移动的物体比对静止或远离的物体表现出更大的敏感性。人类的敏感性增加通常表现为反应时间的增加，从隐约出现到后退，再到静态目标。然而，目前尚不清楚是否有加工优势所享有的隐现运动是由注意系统或运动系统介导的。本研究调查这一点，首先检查是否敏感性是若隐若现的运动本身或某些单眼或双眼线索，构成立体运动的深度。没有一个线索能解释这种隐约的优势。知觉的措施，然后被用来检查性能与最小的参与运动系统。结果表明，隐现和后退运动在吸引注意力方面是等同的，这表明隐现优势确实是由运动系统介导的。这些发现表明，虽然运动本身是足够的注意捕获，运动方向可以启动运动反应。
A wealth of evidence now shows that human and animal observers display greater sensitivity to objects that move toward them than to objects that remain static or move away. Increased sensitivity in humans is often evidenced by reaction times that increase in rank order from looming, to receding, to static targets. However, it is not clear whether the processing advantage enjoyed by looming motion is mediated by the attention system or the motor system. The present study investigated this by first examining whether sensitivity is to looming motion per se or to certain monocular or binocular cues that constitute stereoscopic motion in depth. None of the cues accounted for the looming advantage. A perceptual measure was then used to examine performance with minimal involvement of the motor system. Results showed that looming and receding motion were equivalent in attracting attention, suggesting that the looming advantage is indeed mediated by the motor system. These findings suggest that although motion itself is sufficient for attentional capture, motion direction can prime motor responses.
