两个实验研究的性能，仪器水平按下由大鼠后处理贬值的蔗糖增稠剂产生的建立一个厌恶it.In实验1，大鼠反应少，在灭绝测试后，避免从蔗糖训练后的比例计划，但不遵循等量的训练间隔时间表。这是真的，即使贬值的蔗糖不会作为一个有效的补充剂的比例或间隔时间表。实验2进一步研究了反应时间间隔对评价者评价的不敏感性，通过比较简单消退和评价者评价时的反应时间间隔对评价者评价的不敏感性。再一次，简单灭绝性能不受先前货币贬值的影响。无论是非偶然的还是偶然的介绍，贬值的货币显着降低反应低于灭绝条件下看到的水平。比率，而不是间隔，表现似乎是由知识控制的，但工具的偶然性，编码的具体性质的培训。
Two experiments investigated performance of instrumental level pressing by rats following postconditioning devaluation of the sucrose reinforcer produced by establishing an aversion to it. In experiment 1, rats responded less in an extinction test after being averted from the sucrose following training on a ratio schedule, but not following an equivalent amount of training on an interval schedule. This was true even though the devalued sucrose would not act as an effective reinforcer on either the ratio or interval schedule. Experiment 2 further investigated the insensitivity of interval responding to reinforcer devaluation by comparing test performance under simple extinction with responding when the devalued reinforcer was presented on either a response-contingent or noncontingent schedule during the test. Once again, simple extinction performance was unaffected by prior reinforcer devaluation. Neither noncontingent nor contingent presentations of the devalued reinforcer significantly depressed responding below the level seen in the extinction condition. Ratio, but not interval, performance appears to be controlled by knowledge aobut the instrumental contingency that encodes specific properties of the training reinforcer.
