It has been suggested that schedule-induced behaviors allow organisms to adapt better to temporal regularities of the environment. The main goal of the present study was to observe the effect of schedule-induced drinking (SID) on the performance in fixed-interval (FI) schedules. Rats were exposed to a FI 15-, 30-, or 60-s food reinforcement schedule, and only half of them had access to water in the experimental chamber. Rats with access to water developed SID, which occurred in the first part of the interval, regardless of the FI value, and was followed by an increase in lever pressing rate. There were no substantial differences in the quantitative measures of timing between groups that had or did not have access to water, except for the rats in the FI 15-s group with access to water, who showed longer postreinforcement pauses, possibly attributable to competition between SID and lever pressing. SID did not manifest the scalar property, contrary to lever pressing, but it is proposed that behaviors are displayed serially until the last behavior before the target operant response becomes a discriminative stimulus for that behavior. It is not assumed that the purpose of schedule-induced behaviors is to aid timing, but the development of behavioral patterns might determine the performance of organisms on temporal tasks. Additionally, in some cases competition between responses might exert more control on when the operant behavior occurs than timing. Timing seems to consist in the temporal organization of available behaviors that leads to a specific behavior occurring at a specified time, a single characteristic that typically had come to indicate accurate timing.

对固定间隔表现的日程诱导行为的“时间”功能的评估。

有人提出，日程诱导的行为使生物体能够更好地适应环境的时间规律。本研究的主要目标是观察计划诱导饮酒 (SID) 对固定间隔 (FI) 计划表现的影响。大鼠暴露于 FI 15-、30- 或 60-s 食物强化计划，并且只有一半的老鼠可以在实验室内喝水。接触水的大鼠出现 SID，发生在间隔的第一部分，无论 FI 值如何，然后是杠杆按压率的增加。除了有水的 FI 15-s 组中的大鼠显示出更长的强化后停顿外，有或没有水的组之间在时间的定量测量上没有实质性差异，可能归因于 SID 和杠杆压力之间的竞争。与杠杆按压相反，SID 没有表现出标量属性，但有人提出行为是连续显示的，直到目标操作性反应成为该行为的判别性刺激之前的最后一个行为。不假定日程诱导行为的目的是帮助计时，但行为模式的发展可能决定生物体在时间任务上的表现。此外，在某些情况下，响应之间的竞争可能对操作行为发生的时间比对时间施加更多的控制。时间似乎包括可导致特定行为在特定时间发生的可用行为的时间组织，这是一个通常表明准确时间的单一特征。
