In 2 experiments, rats were trained in a Morris pool to find a hidden platform in the presence of 1 landmark. After acquisition, the rats were tested without the platform. Experiment 1 tested whether the size of a landmark and its relative distance from the platform are additive effects. On test, the rats' best performance was with a near and big landmark; intermediate performance was with either a near and small landmark or a far and big one; and the worst performance was with a far and small landmark. The results of Experiment 2 suggested that the different distances from the goal of the 2 landmarks might not be sufficient to explain the previous results.
在两项实验中,大鼠在莫里斯水池中接受训练,在有一个地标物的情况下寻找隐藏的平台。训练完成后,对大鼠进行无平台测试。实验1测试地标物的大小及其与平台的相对距离是否具有累加效应。在测试中,大鼠表现最佳的情况是有一个靠近且较大的地标物;中等表现是有一个靠近且较小的地标物或一个远离且较大的地标物;表现最差的情况是有一个远离且较小的地标物。实验2的结果表明,两个地标物与目标的不同距离可能不足以解释先前的结果。
