An experiment using a predictive learning task with college students evaluated the impact of a stimulus associated with extinction on an AAB renewal design. Four groups of participants learned a specific relationship between two cues (X and Y) and two outcomes (O1 and O2) in Context A during the first phase. Subsequently, both cues were subjected to extinction in the same Context A. During the Test, extinction was in effect for both cues; one group experienced it in Context A (AAA), while the other three groups were tested in a second Context B. We observed a reduction in the AAB renewal effect when participants received a stimulus associated with extinction (AAB*), but not when testing involved presenting a new stimulus (AAB). However, the reductive effect of the extinction reminder was not observed when the stimulus was presented only during the 75% of the extinction trials (AAB*75). These findings suggest that, under certain circumstances, the level of association of the extinction reminder with extinction might affect its efficacy in reducing response recovery.
一项针对大学生的使用预测性学习任务的实验，评估了与消退相关的刺激对AAB更新设计的影响。在第一阶段，四组参与者在情境A中学习了两个线索（X和Y）与两个结果（O1和O2）之间的特定关系。随后，两个线索在同一情境A中都经历了消退。在测试阶段，两个线索的消退均有效；一组在情境A中经历消退（AAA），而其他三组在第二个情境B中进行测试。我们观察到，当参与者接受与消退相关的刺激时（AAB*），AAB更新效应会降低，但当测试涉及呈现新刺激时（AAB）则不会。然而，当刺激仅在75%的消退试验中呈现时（AAB*75），未观察到消退提醒的还原效应。这些发现表明，在某些情况下，消退提醒与消退的关联程度可能会影响其在减少反应恢复方面的功效。
