在三个实验中，大鼠作为受试者，我们开发了一个灭绝程序使用莫里斯池。这些动物被训练找到一个隐藏在固定位置的平台，然后进行灭绝试验，将平台从游泳池中移走。当训练和消退在相同的背景下进行，并且消退和测试之间间隔一段时间时，观察到学习的自发恢复。另一方面，在与用于训练的环境不同的环境中接受灭绝的那些大鼠在间隔96小时后在灭绝环境中进行测试时未能显示出学习的自发恢复。然而，当在训练环境中进行测试时，他们确实显示出空间学习的更新。这些结果表明，在空间域中的消光行为类似于在标准调节制剂中的消光。
In three experiments in which rats were used as subjects, we developed an extinction procedure using a Morris pool. The animals were trained to find a hidden platform located at a fixed position and were then given extinction trials in which the platform was removed from the pool. When training and extinction were carried out in the same context and time was allowed to elapse between extinction and test, spontaneous recovery of learning was observed. On the other hand, those rats that received extinction in a context different from the one used for training failed to show spontaneous recovery of learning when tested in the extinction context after an interval of 96 h. However, they did show renewal of spatial learning when tested in the training context. These results show that extinction in the spatial domain behaves like extinction in standard conditioning preparations.
