In an experiment with rats, an appetitive conditioning method was used to investigate the generality of the hypothesis that extinction should arouse attention to contextual cues, resulting in all learning in that context becoming context specific. Rats received appetitive conditioning with a tone either while extinction of a flasher occurred (Group With Extinction) or while it did not (Group No Extinction). Half of each group was subsequently tested in extinction in the context in which training had taken place or in a different context. The results revealed a three-way interaction of extinction and context with trials, in a direction opposite to the one the hypothesis would suggest. When rats were tested in a different context, there was generally better responding in Group With Extinction than in Group No Extinction. In the same context, there was generally lower responding in Group With Extinction than in Group No Extinction. Subsequent testing showed an ABA recovery effect. Results are discussed in terms of the challenges they pose for the revised retrieval theory presented by Callejas-Aguilera and Rosas (2011).
在一项用大鼠进行的实验中，采用了一种奖赏性条件作用方法来研究这样一个假设的普遍性：消退会引起对情境线索的注意，从而导致在该情境中的所有学习都变得具有情境特异性。大鼠在闪光刺激消退期间（消退组）或未消退期间（无消退组）接受了音调奖赏性条件作用。随后，每组中的一半大鼠在训练发生的情境中或在不同情境中接受消退测试。结果显示，消退、情境与试验之间存在三因素交互作用，其方向与该假设所暗示的方向相反。当在不同情境中对大鼠进行测试时，消退组的反应通常比无消退组更好。在相同情境中，消退组的反应通常比无消退组更低。后续测试显示出ABA恢复效应。根据这些结果对Callejas-Aguilera和Rosas（2011年）提出的修订检索理论所构成的挑战进行了讨论。
