大鼠可以使用“近端”和“远端”线索来定位环境中的目标物体（Morris，1981）。在近端线索的情况下，空间上与目标共同出现的局部刺激可用于指导行为。在远端线索的情况下，没有线索，共同出现的目标对象，因此直接定位的目标，大鼠必须了解的空间位置的目标相对于远端线索。通过Morris水迷宫实验，我们发现这两种导航行为在个体发育过程中是分离的。只有17天大的老鼠能够使用近端线索来定位安全的平台。然而，直到大鼠20天大时，它们才开始显示出最小的远端线索利用证据。对照实验表明，17日龄的受试者在远端问题上的失败可能是由于他们的空间学习技能不足。这些结果被解释在杰克逊的角度来看，脑行为的关系。
Rats can use both "proximal" and "distal" cues to locate goal objects in their environments (Morris, 1981). In the proximal-cue situation, local stimuli that spatially co-occur with the goal are available to guide behavior. In the distal-cue situation, there are no cues that co-occur with the goal object; thus to directly locate the goal, the rat must learn about the spatial location of the goal relative to distal cues. Using the Morris water maze, we found that these two navigation behaviors are dissociated during ontogeny. Rats only 17-days-old are capable of using proximal cues to locate a safe platform. It was not until the rats were 20-day-old, however, that they began to display minimal evidence of distal-cue utilization. Control experiments indicated that the 17-day-old subjects'' failure on the distal problem was likely due to their inadequate spatial learning skills. These results were interpreted within a Jacksonian perspective of brain-behavior relations.
