In two instrumental conditioning experiments with rats, we examined the impacts of acquisition and extinction cues on ABC renewal of instrumental behavior. Animals were reinforced with food for lever pressing in one context, followed by extinction of the response in a second one. Presentations of a brief tone accompanied extinction in Experiment 1 (extinction cue), and acquisition in Experiment 2 (acquisition cue). A final test in a third context revealed that instrumental responding was decreased in the presence of the extinction cue, whereas it was increased in the presence of the acquisition cue. We discuss theoretical and clinical implications of our results.
在两项大鼠工具性条件反射实验中，我们研究了获得和消退线索对工具性行为 ABC 复现的影响。动物在一种情境下因按压杠杆而获得食物强化，随后在另一种情境下消退该反应。在实验 1 中，短暂的音调与消退同时呈现（消退线索），而在实验 2 中，与获得同时呈现（获得线索）。在第三个情境下的最终测试表明，在消退线索存在的情况下，工具性反应减少，而在获得线索存在的情况下，工具性反应增加。我们讨论了我们结果的理论和临床意义。
