The resurgence of temporal patterns of key pecking by pigeons was investigated in two experiments. In Experiment 1, positively accelerated and linear patterns of responding were established on one key under a discrete-trial multiple fixed-interval variable-interval schedule. Subsequently, only responses on a second key produced reinforcers according to a variable-interval schedule. When reinforcement on the second key was discontinued, positively accelerated and linear response patterns resurged on the first key, in the presence of the stimuli previously correlated with the fixed- and variable-interval schedules, respectively. In Experiment 2, resurgence was assessed after temporal patterns were directly reinforced. Initially, responding was reinforced if it approximated an algorithm-defined temporal pattern during trials. Subsequently, reinforcement depended on pausing during trials and, when it was discontinued, resurgence of previously reinforced patterns occurred for each pigeon and for 2 of 3 pigeons during a replication. The results of both experiments demonstrate the resurgence of temporally organized responding and replicate and extend previous findings on resurgence of discrete responses and spatial response sequences.
在两项实验中研究了鸽子关键啄食的时间模式的再现。在实验 1 中，在离散试验多固定间隔可变间隔程序下，对一个键建立了正加速和线性反应模式。随后，只有第二个键上的反应根据可变间隔程序产生强化。当第二个键上的强化停止时，在分别与固定间隔和可变间隔程序相关联的刺激存在的情况下，第一个键上会再次出现正加速和线性反应模式。在实验 2 中，在直接强化时间模式后评估了再现。最初，如果在试验期间的反应接近算法定义的时间模式，则进行强化。随后，强化取决于试验期间的停顿，当停止强化时，每个鸽子和复制试验中的 3 个鸽子中的 2 个都会出现先前强化的模式再现。这两个实验的结果都证明了时间组织反应的再现，并且复制和扩展了先前关于离散反应和空间反应序列再现的发现。
