中文摘要：

人类具有很强的识别生物体运动信息的能力,甚至当运动信息仅是由附着在头部和一些重要关节上的光点的运动组成时,观察者对该信息检测和编码的优势依然存在。光点生物运动信息包含整体信息（如整体形状）和局部信息（如各个点的运动轨迹）。先前的绝大部分研究强调整体形状在生物运动知觉中的作用。最近有研究表明去除了整体结构信息的局部生物运动仍然存在加工优势,揭示了局部生物运动本身可能包含了一些特异性信息。因此生物运动知觉并非单一现象,而是一种具有不同加工机制（基于整体结构和基于局部运动）的多水平现象。

英文摘要：

Humans are remarkably adept at recognizing the motion of biological entities in complex visual scenes, even when it is depicted with a handful of point-lights attached to the head and major joints. Though much simplified, such point-light biological motion consists of both global configuration and local motion trajectories. Whereas most previous studies have emphasized the contribution of global form to biological motion perception, it has recently been shown that local biological motion can be processed independent of global configuration, revealing that local biological motion alone carries unique biological properties. Taken together, the evidence so far suggests that biological motion perception is a multilevel process in which each level makes distinct contributions.
