为什么人类观察者对人类的运动特别敏感？七个实验通过比较在步态速度和身份识别任务中熟悉的、不寻常的和不可能的步态的点光显示的视觉敏感性，研究了视觉经验和运动过程在人类运动感知中的作用。在这两个任务中，对物理上可能的步态的视觉敏感性优于对物理上不可能的步态的视觉敏感性，支持人类运动感知的感知-动作耦合理论。视觉经验影响步行者身份知觉，但不影响步态-速度辨别。因此，运动经验和视觉经验都定义了对人体运动的视觉敏感性。生态学的观点可以用来定义对人类运动的经验依赖敏感性的必要条件。
Why are human observers particularly sensitive to human movement? Seven experiments examined the roles of visual experience and motor processes in human movement perception by comparing visual sensitivities to point-light displays of familiar, unusual, and impossible gaits across gait-speed and identity discrimination tasks. In both tasks, visual sensitivity to physically possible gaits was superior to visual sensitivity to physically impossible gaits, supporting perception-action coupling theories of human movement perception. Visual experience influenced walker-identity perception but not gait-speed discrimination. Thus, both motor experience and visual experience define visual sensitivity to human movement. An ecological perspective can be used to define the conditions necessary for experience-dependent sensitivity to human movement.
