老鼠被训练去寻找隐藏在木屑下的食物奖励，木屑藏在一个正方形的围栏中心，这个围栏是根据环境的整体几何形状设计的。然后，在形状和大小不同的外壳（矩形、双面正方形和等边三角形外壳）中对它们进行测试。结果表明，大鼠将其寻找位置的能力转移到了新的围栏中。我们的研究结果为空间认知的进化根源需要几何关系的原始编码这一假设提供了证据，正如已经在大鼠的其他任务中所显示的那样。
Rats were trained to search for a food reward hidden under sawdust in the center of a square-shaped enclosure designed to force orientation on the basis of the overall geometry of the environment. They were then tested in a number of enclosures differing in shape and in size (rectangular-, double-side square-, and equilateral triangle-shaped enclosures). Results showed that rats transferred their place-finding ability to the novel enclosures. Our results add evidence to the hypothesis that the evolutionary roots of spatial cognition entail a primitive encoding of geometric relationships, as already shown using other tasks in rats.
