摘要：

In two experiments, rats were trained to find a hidden platform in a Mori-is pool in the presence of two landmarks. Landmark B was present on all training trials, on half the trials accompanied by landmark A, oil the remainder by landmark C. For rat, in Group Bn, B was near the location of the platform; for those in Group Bf, B was far from the platform. Group Bn performed better than Group Bf on test trials to B alone, but significantly worse on test trials to a new configuration formed by A and C. Thus, the spatial proximity of B to the platform affected not only how well it could be used to locate the platform, but also its ability to prevent learning about other landmarks.
