This reply notes the importance of data from variable-time schedules for resolving the issue of whether competition from magazine approach behavior is a major factor responsible for the concentration of schedule-induced drinking early in interpellet intervals. Pellón and Killeen propose that this temporal distribution of schedule-induced drinking reflects the effectiveness of adventitious reinforcement of this behavior over a delay, as detailed in their model. However, there is no evidence to support either of their key assumptions: (a) that schedule-induced behaviors are maintained by adventitious reinforcement ("are operants") and (b) that behaviors vary in their sensitivity to a delay before the subsequent occurrence of a reinforcer.
即来自杂志接近行为的竞争是否是导致颗粒间间隔早期日程诱导饮水集中的主要因素。佩隆和基林提出，日程诱导饮水的这种时间分布反映了这种行为在延迟期间偶然强化的有效性，正如他们模型中所详述的那样。然而，没有证据支持他们的两个关键假设：（a）日程诱导行为是由偶然强化维持的（“是操作性行为”），以及（b）行为对强化物随后出现之前的延迟的敏感性各不相同。
