A synchronous-reinforcement schedule is a type of schedule of covariation in which the onset and offset of the reinforcer covaries with the onset and offset of behavior. This study was a proof-of-concept demonstration of the efficacy of synchronous reinforcement for on-task behavior (completing a preacademic skill) and an evaluation of preschoolers' preference for this schedule in comparison to a more traditional schedule of reinforcement. Specifically, we compared the effects of a synchronous-reinforcement schedule to one in which continuous access to stimuli was delivered at the end of the session and yoked to the duration of on-task behavior that occurred during the session (accumulated reinforcement). Results showed the synchronous-reinforcement schedule was more effective for increasing on-task behavior and preferred by most participants.
同步强化时间表是一种共变时间表，其中强化物的开始和结束与行为的开始和结束共变。这项研究是对同步强化对任务行为（完成预学术技能）的功效的概念验证演示，以及对学龄前儿童对这种时间表的偏好与更传统的强化时间表的评估。具体来说，我们比较了同步强化时间表和一种在课程结束时提供连续刺激并与课程期间发生的任务行为（累积强化）持续时间挂钩的时间表的效果。结果表明，同步强化时间表更有效地增加了任务行为，并且大多数参与者更喜欢这种时间表。
