Rats deprived of water were placed, for 4-minute sessions, into a chamber containing a hole in one wall. After several sessions the number of times these rats explored the hole markedly decreased. Rats given access to water at the hole for a brief period explored the hole more frequently than controls, when they were tested later. This increase in hole explorations was abolished when the water reinforcement was followed by electro-convulsive shock but not when followed by foot shock.
将缺水的大鼠放入一个有洞的小室中,每次放置4分钟。经过几次这样的实验后,这些大鼠探索洞口的次数明显减少。当后来对大鼠进行测试时,那些曾在洞口短暂获得水的大鼠比对照组更频繁地探索洞口。当水强化后紧接着进行电惊厥休克时,这种对洞口探索次数的增加就消失了,但当紧接着进行足部电击时则不会消失。
