先前关于行为动量的实验表明，在刺激存在的情况下，对操作性行为消退的相对抵抗力取决于与该刺激相关的强化率，即使其中一些强化独立于行为发生。我们提出了三个实验研究是否在刺激的存在下，强化率同样调制相对复发的操作性行为所产生的恢复，复苏，和更新的范例。在基线条件下，鸽子响应食物强化可变间隔120秒的时间表，在交替期间暴露于两个刺激安排的多个时间表。额外的响应独立的食物介绍也提供了在存在的多个时间表的刺激之一。与以前的研究一致，基线反应率较低的刺激与增加的反应独立的强化的存在下，和灭绝的相对阻力更大的刺激的存在下。此外，灭绝后，相对复发的反应所产生的恢复，复苏，和更新的范例也更大的刺激与更高的强化率的存在。我们认为，从行为动量理论灭绝的模型可能是有用的理解这些结果。
Previous experiments on behavioral momentum have shown that relative resistance to extinction of operant behavior in the presence of a stimulus depends upon the rate of reinforcement associated with that stimulus, even if some of those reinforcers occur independently of the behavior. We present three experiments examining whether the rate of reinforcement in the presence of a stimulus similarly modulates relative relapse of operant behavior produced by reinstatement, resurgence, and renewal paradigms. During baseline conditions, pigeons responded for food reinforcement on variable-interval 120-s schedules in alternating periods of exposure to two stimuli arranged by a multiple schedule. Additional response-independent food presentations were also delivered in the presence of one of the multiple-schedule stimuli. Consistent with previous research, baseline response rates were lower in the presence of the stimulus with the added response-independent reinforcement, and relative resistance to extinction was greater in the presence of that stimulus. In addition, following extinction, relative relapse of responding produced by reinstatement, resurgence, and renewal paradigms also was greater in the presence of the stimulus associated with the higher rate of reinforcement. We suggest that a model of extinction from behavioral momentum theory may be useful for understanding these results.
