Abrupt discontinuation of functional communication training can cause resurgence of challenging behavior. Teaching multiple alternative responses in sequence (serial training) may reduce resurgence, relative to teaching a single alternative. However, previous evaluations of serial training included a different number of response options across comparison conditions. In Experiment 1, we varied both training type (single and serial) and number of response options, and replicated previous findings showing that more resurgence occurred following single training relative to serial training. In Experiment 2, we varied the training type while holding the number of alternative responses constant and obtained no consistent differences in resurgence. In Experiment 3, we varied the number of alternative responses while holding training type constant (i.e., single). More resurgence occurred in the condition with fewer response options, suggesting that the number of available alternative responses, and not explicit serial training of alternatives, was critical to outcomes.
功能沟通训练的突然中断可能会导致挑战性行为的复发。与教授单一替代反应相比，按顺序教授多个替代反应（序列训练）可能会减少复发。然而，之前对序列训练的评估包括在比较条件下替代反应选项的数量不同。在实验 1 中，我们同时改变了训练类型（单一和序列）和替代反应选项的数量，并复制了先前的发现，即与序列训练相比，单一训练后更可能出现更多的复发。在实验 2 中，我们在保持替代反应数量不变的情况下改变了训练类型，没有发现复发有一致的差异。在实验 3 中，我们在保持训练类型不变的情况下改变了替代反应的数量（即单一）。在替代反应数量较少的情况下，复发的情况更多，这表明替代反应的数量，而不是替代反应的明确序列训练，对结果至关重要。
