当原木燃烧时，它会从一块木头变成一堆灰。这样的状态变化是物体变化最戏剧性的方式之一，不仅仅是位置或方向的变化。心智如何代表状态的变化？视觉认知的一个基本结果是记忆推断运动物体的位置--一种被称为表征动量的扭曲。在这里，五个实验(N=400个成年人)利用这一现象来研究状态空间中的心理表征。观看物体状态变化(例如，冰融化、原木燃烧或葡萄枯萎)的参与者记得它们比实际情况变化更大(例如，更多地融化、燃烧或枯萎)。这种模式扩展到几种类型的状态变化，超越了它们的低层次属性，甚至依附于它们在状态空间中的自然轨迹。因此，对物体的心理表征积极地结合了它们是如何变化的--不仅是它们与环境的关系，而且还包括它们的本质。
When a log burns, it transforms from a block of wood into a pile of ash. Such state changes are among the most dramatic ways objects change, going beyond mere changes of position or orientation. How does the mind represent changes of state? A foundational result in visual cognition is that memory extrapolates the positions of moving objects-a distortion called representational momentum. Here, five experiments (N = 400 adults) exploited this phenomenon to investigate mental representations in state space. Participants who viewed objects undergoing state changes (e.g., ice melting, logs burning, or grapes shriveling) remembered them as more changed (e.g., more melted, burned, or shriveled) than they actually were. This pattern extended to several types of state changes, went beyond their low-level properties, and even adhered to their natural trajectories in state space. Thus, mental representations of objects actively incorporate how they change-not only in their relation to their environment, but also in their essential qualities.
