One experiment used a free operant procedure with rats to compare ABA, AAB and ABC renewal by using a within-subject testing procedure. All rats were first trained to press a lever for food in context A. Lever pressing was then extinguished in either context A or context B. For rats in the groups ABA and ABC extinction took place in context B, while the rats in group AAB received extinction in the same context in which acquisition took place (context A). Finally, all rats were tested for renewal in two sessions. One extinction session was carried out in the same extinction context and another session in a different context. Rats in the group ABA were tested in context B and in context A; rats in the group AAB were tested in contexts A and B, whereas the group ABC was tested in contexts B and C. The results of the ANOVA showed context renewal since all groups had higher rates of responding when they were tested outside the extinction context, F(2, 21) = 15.32, p = .001, ηp 2 = .59; however, AAB and ABC renewal was lesser than ABA renewal, F(1, 21) = 16.70, p = .0001, ηp 2 = .61.
一项实验采用大鼠自由操作程序，通过受试者内测试程序比较ABA、AAB和ABC更新。所有大鼠首先在情境A中训练按压杠杆获取食物。然后在情境A或情境B中消除杠杆按压行为。ABA组和ABC组的大鼠在情境B中进行消退训练，而AAB组的大鼠在获取训练的相同情境（情境A）中进行消退训练。最后，所有大鼠分两阶段进行更新测试。一个消退阶段在相同的消退情境中进行，另一个阶段在不同情境中进行。ABA组的大鼠在情境B和情境A中进行测试；AAB组的大鼠在情境A和情境B中进行测试，而ABC组在情境B和情境C中进行测试。方差分析结果显示存在情境更新，因为所有组在消退情境之外进行测试时反应率更高，F(2, 21) = 15.32，p = .001，ηp 2 = .59；然而，AAB和ABC更新小于ABA更新，F(1, 21) = 16.70，p = .0001，ηp 2 = .61。
