Animals and humans receive the most critical information from parts of the environment that are immediately inaccessible and highly dynamic. The brain must effectively process potential interactions between elements in such an environment to make appropriate decisions in critical situations. We trained male Long-Evans rats to discriminate static and dynamic spatial stimuli and to generalize novel dynamic spatial stimuli displayed on an inaccessible computer screen. We provide behavioral evidence indicating that rats encode dynamic visuospatial situations by constructing internal static representations that capture meaningful future interactions between objects. These observations support previous findings in humans that such internal static representations can encapsulate relevant spatiotemporal information of dynamic environments. This mechanism would allow animals and humans to process complex time-changing situations neatly.
动物和人类从那些直接无法触及且高度动态的环境部分接收最关键的信息。大脑必须有效地处理这种环境中各元素之间的潜在相互作用，以便在关键情况下做出恰当的决策。我们训练雄性长 Evans 大鼠区分静态和动态空间刺激，并对显示在无法触及的电脑屏幕上的新型动态空间刺激进行泛化。我们提供的行为证据表明，大鼠通过构建内部静态表征来编码动态视觉空间情境，这些表征捕捉了物体之间有意义的未来相互作用。这些观察结果支持了之前在人类中的发现，即这种内部静态表征可以封装动态环境的相关时空信息。这种机制将使动物和人类能够巧妙地处理复杂的随时间变化的情况。
