Rats reared in either socially isolated or control environments were trained to bar press for food on a variable interval schedule of reinforcement, beginning at 125 days of age for 37 consecutive days. Following this phase the subjects were tested for response persistence during an extinction test. Next, the subjects were compared on measures of spontaneous recovery and the rate of response reacquisition when the reinforcement contingencies were once again reinstated. Though no differences were discerned between the groups on measures of acquisition, maintenance, and reacquisition, isolated rats emitted many more responses than the controls during extinction testing.
在社会隔离环境或对照环境中饲养的大鼠，从125日龄开始，按照可变间隔强化程序接受按压杠杆获取食物的训练，持续37天。在此阶段之后，在消退测试中对受试者的反应持续性进行测试。接下来，当再次恢复强化条件时，比较受试者在自发恢复和反应重新习得率方面的指标。虽然在习得、维持和重新习得指标上两组之间没有差异，但在消退测试中，隔离饲养的大鼠比对照组发出的反应更多。
