Synchronous schedules of reinforcement are those in which the onset and offset of a reinforcer are synchronized with the onset and offset of a target behavior. The current study replicated and extended Diaz de Villegas et al. (2020) by comparing synchronous reinforcement to noncontingent stimulus delivery while evaluating on-task behavior of school-age children. A concurrent-chains preference assessment was then used to determine the preferred schedule. Results indicated that the synchronous schedule was more effective than the continuous, noncontingent delivery of the stimulus at increasing on-task behavior but that the children preferred noncontingent delivery. Additionally, the use of synchronous and noncontingent delivery did not alter the children's preference for the task.
同步强化时间表是指强化的开始和结束与目标行为的开始和结束同步的时间表。本研究通过比较同步强化与非关联刺激呈现，同时评估学龄儿童的任务行为，复制和扩展了 Diaz de Villegas 等人（2020 年）的研究。然后使用并行链偏好评估来确定首选时间表。结果表明，与连续、非关联的刺激呈现相比，同步时间表更能有效地增加任务行为，但儿童更喜欢非关联的刺激呈现。此外，同步和非关联呈现的使用并没有改变儿童对任务的偏好。
