Resurgence is a reliable, transient effect that only occasionally is replicated more than once within a single experiment or subject. In the present experiments, within-session resurgence was generated repeatedly by dividing individual sessions into three phases (Training, Alternative-Reinforcement, and Resurgence-Test). In Experiments 1 and 2, resurgence reliably occurred in most of the 22-30 daily sessions when responding was reinforced on, respectively, fixed- and variable-interval schedules. Resurgence magnitude and duration did decrease across replications for some subjects, but not for others. To examine the utility of the procedure in studying the effects of an independent variable on resurgence, in Experiment 3 the effects of rich and lean baseline and alternative reinforcement rates on resurgence were compared. The target response was eliminated more rapidly, resurgence occurred more often, and usually was greater following rich alternative reinforcement rates. Resurgence was of greater magnitude when the baseline reinforcement rate was relatively lean compared to the alternative reinforcement rate. These experiments provide a reliable method for generating resurgence within individual sessions, instead of across multiple-session conditions, that can be repeated over many successive sessions.
再现是一种可靠的、短暂的效应，在单次实验或被试中偶尔会不止一次地复制。在本实验中，通过将单个会话分为三个阶段（培训、替代强化和再现测试），在会话内产生了重复的再现。在实验 1 和 2 中，当响应分别在固定和可变间隔时间表上得到强化时，在 22 到 30 天的日常会话中的大多数会话中，再现可靠地发生。对于一些被试，再现的幅度和持续时间在重复中确实有所下降，但对于其他被试则没有。为了研究独立变量对再现的影响，在实验 3 中比较了丰富和贫瘠基线以及替代强化率对再现的影响。在基线强化率相对贫瘠与替代强化率相比时，目标反应被更快地消除，再现发生得更频繁，并且通常更大。当基线强化率相对替代强化率较贫瘠时，再现的幅度更大。这些实验提供了一种可靠的方法，可在单个会话中产生再现，而不是在多个会话条件下产生，并且可以在许多连续的会话中重复。
