| 中文摘要: |
| 当物体迫近观察者或观察者迫近物体时，观察者（人或动物）利用何种视觉线索成功地实现躲避行为或截取行为？已有研究
显示物体在观察者视网膜上视像均匀扩大的速率（Tau 线索）可直接为人或动物提供即将碰撞时间信息，从而使得观察者可以直
接指挥肢体，做出反应。本综述从行为学和认知神经基础上总结了支持Tau 线索的证据，并对今后关于即将碰撞时间估计视觉线
索研究趋势提出建议。 |
| 英文摘要: |
| When a moving object is approaching an observer or an observer is approaching an object, human and animals can
use visual information about the impending collision to extract time-to-collision variable and use this information to guide their behaviors
such as avoidance. This paper reviews behavioral and physiological evidence for processing of time-to-collision, described the Tau
hypothesis, the revised Tau hypothesis and the general Tau theory. Some possible directions for future studies are also discussed. |
