一张动作照片可以传达生动的运动感。通过观看照片来推断运动是否涉及与观看物理运动时所使用的相同的神经和心理表征？在这项研究中，我们测试了隐含运动是否由与真实运动感知相关的相同方向选择信号来表示。我们利用了运动后效，一种视觉运动错觉。三项实验表明，观看一系列在特定方向上暗示运动的静态照片会产生相反方向的运动后效应，正如使用真实运动测试探针所评估的那样。从照片中描绘的运动到真实运动的适应转移表明，对隐含运动的感知会激活方向选择电路，该电路也参与处理真实运动。
A photograph of an action can convey a vivid sense of motion. Does the inference of motion from viewing a photograph involve the same neural and psychological representations used when one views physical motion? In this study, we tested whether implied motion is represented by the same direction-selective signals involved in the perception of real motion. We made use of the motion aftereffect, a visual motion illusion. Three experiments showed that viewing a series of static photographs with implied motion in a particular direction produced motion aftereffects in the opposite direction, as assessed with real-motion test probes. The transfer of adaptation from motion depicted in photographs to real motion demonstrates that the perception of implied motion activates direction-selective circuits that are also involved in processing real motion.
