| 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。

| Abstract: | 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. |
