实验证明，老鼠可以快速学会定位它们永远看不见、听不到或闻不到的物体，只要它保持在相对于远端房间线索的固定空间位置。四组老鼠被允许从不透明的水中逃到一个平台上，这个平台要么在水面上，要么在水面下，要么在固定的位置，要么在不同的位置。除了逃生平台在水面以下并四处移动的那一组外，学习进展得很快。转移测试显示，平台在水下但在固定位置的小组采用了空间位置搜索策略。第二个实验进一步研究了这种学习，揭示了当大鼠被要求从一个新的起始位置接近平台时的瞬时转移。这两项研究的数据都与最近在大鼠空间记忆方面的工作有关。介绍了空间记忆敏锐度的概念，所采用的方法可能为空间记忆与经典条件反射和工具条件反射的比较提供了一种新的方法。
It was demonstrated that rats can rapidly learn to locate an object that they can never see, hear or smell provided it remains in a fixed spatial location relative to distal room cues. Four groups of rats were permitted to escape from opaque water onto a platform which was either just above or just below the water surface, and in either a fixed or varied location. Learning occurred rapidly except for the group for whom the escape platform was below the water surface and moved about from place to place. Transfer tests revealed that a spatial location search strategy was employed by the group for whom the platform was below water but in a fixed location. A 2nd experiment investigated this learning further, revealing instantaneous transfer when the rats were required to approach the platform from a novel starting position. The data of both studies are discussed in relation to recent work on spatial memory in the rat. The concept of the acuity of spatial memory is introduced and the procedures used may provide a new approach to comparing spatial memory with classical and instrumental conditioning.
