老鼠被要求在游泳池的角落里找到一个形状独特的水下平台。平台附近的一个地标并没有干扰水池形状对搜索平台的控制。这一结果是通过遮蔽和阻断设计观察到的。地标和游泳池的形状获得控制搜索平台的容易程度的比较表明，遮蔽和阻挡的失败并不是地标比游泳池的形状更不突出的结果。这些结果并不容易用联想学习的理论来解释，但它们与关于环境形状的学习发生在一个专用模块中的说法是一致的，该模块排除了关于单个地标的重要性的信息。
Rats were required to find a submerged platform in the corner of a swimming pool with a distinctive shape. A landmark near the platform did not interfere with the control acquired by the pool's shape over searching for the platform. This outcome was observed with an overshadowing and a blocking design. A comparison of the ease with which the landmark and the pool's shape gained control over searching for the platform indicates that the failure of overshadowing and blocking was not a consequence of the landmark being less salient than the shape of the pool. The results are not readily explained by theories of associative learning, but they are consistent with the claim that learning about the shape of the environment takes place in a dedicated module, which excludes information about the significance of individual landmarks.
