有人认为，对形状的感知也常常伴随着对时间的感知。例如，一块饼干少咬了一口，就会被看作是一块随后被咬了一口的完整饼干。然而，这些观察结果是否真实地反映了视觉加工过程，一直都不清楚。为了探索这种可能性，我们测试了在静态形状中对历史的感知是否真的会引起虚幻的运动感知。观察者观察一个正方形变成一个截短的形状，其中一部分缺失，他们报告这种变化是突然的还是逐渐的。当缺失部分的轮廓暗示着某种历史入侵时（就像当一个人把手指戳进一团粘土时），观察者实际上看到了这种入侵的发生：这种变化看起来是渐进的，即使它实际上是突然的，在一种转型的明显运动中。这提供了惊人的现象学证据，证明视觉涉及从静态形状重建因果历史。
The perception of shape, it has been argued, also often entails the perception of time. A cookie missing a bite, for example, is seen as a whole cookie that was subsequently bitten. It has never been clear, however, whether such observations truly reflect visual processing. To explore this possibility, we tested whether the perception of history in static shapes could actually induce illusory motion perception. Observers watched a square change to a truncated form, with a piece of it missing, and they reported whether this change was sudden or gradual. When the contours of the missing piece suggested a type of historical intrusion (as when one pokes a finger into a lump of clay), observers actually saw that intrusion occur: The change appeared to be gradual even when it was actually sudden, in a type of transformational apparent motion. This provides striking phenomenological evidence that vision involves reconstructing causal history from static shapes.
