Slaton and Hanley (2016) compared the effects of multiple and chained schedules on stereotypy and item engagement for 2 individuals who exhibited automatically maintained motor stereotypy. Contingent access to motor stereotypy (i.e., chained schedules) was more effective than time-based access (i.e., multiple schedules) at reducing motor stereotypy, increasing item engagement, and establishing stimulus control for both participants. We systematically replicated Slaton and Hanley with 2 participants by a) targeting vocal stereotypy, b) including response interruption and redirection as a treatment component across conditions, c) conducting sessions in the natural environment with teaching assistants as change agents, and d) conducting an analysis of the effective treatment component(s). Chained schedules were more effective for 1 participant, whereas both treatments were effective for the other participant. The component analysis showed that different components were necessary for effective treatment for each participant.
斯拉顿和汉利（2016）比较了多项和连锁时间表对刻板行为和项目参与的影响，这两个人表现出自动维持的运动刻板行为。运动刻板行为的偶然获得（即连锁时间表）比基于时间的获得（即多项时间表）更有效地减少运动刻板行为，增加项目参与，并为两个参与者建立刺激控制。我们通过以下方式系统地复制了斯拉顿和汉利的研究：a）针对发声刻板行为，b）在所有条件下包括反应中断和重定向作为治疗成分，c）在自然环境中由助教作为改变者进行会议，以及 d）进行有效治疗成分的分析。连锁时间表对 1 名参与者更有效，而两种治疗方法对另一名参与者都有效。组件分析表明，每个参与者的有效治疗需要不同的组件。
