Six pigeons responded on two keys in each of three signalled multiple-schedule components, and resistance to disruption of responding on one (target) key by extinction and by response-independent food presented during inter-component blackouts was studied. Alternative reinforcement of different magnitudes was contingent on pecking a non-target key in two components, and in the third only the target response was reinforced. Resistance to change varied with the overall quantity of reinforcement in the component, regardless of whether reinforcers were contingent on the target or non-target response, but did not differ across the two key locations. These results using different magnitudes of reinforcement confirm previous findings using rate of reinforcement as the variable, and suggest that resistance to change is dependent on stimulus-reinforcer rather than response-reinforcer contingencies.
六只鸽子在三个信号多重时间表组件中的每一个组件的两个按键上做出反应，并研究了在组件间停电期间通过消退以及通过呈现与反应无关的食物来干扰在一个（目标）按键上的反应的抗性。在两个组件中，不同强度的交替强化取决于啄击一个非目标按键，而在第三个组件中，只有目标反应得到强化。对变化的抗性随组件中强化的总量而变化，无论强化物是取决于目标反应还是非目标反应，但在两个按键位置之间没有差异。这些使用不同强化强度的结果证实了以前使用强化速率作为变量的研究结果，并表明对变化的抗性取决于刺激-强化物而非反应-强化物的 contingency。 （注：最后一个单词“contingency”在语境中可能有特定含义，这里直接保留英文，因为准确翻译需结合更专业的医学或行为学背景知识，仅按要求逐字翻译可能会影响对整体内容的理解。）
