Improving on-task behavior can allow individuals to access more learning opportunities and is especially relevant for individuals with developmental disabilities. The current study examined the efficacy of an intervention package that used percentile schedule of reinforcement, feedback, and application of lower limits to changes in criteria to increase on-task behaviors in children with developmental disabilities. Using a nonconcurrent multiple baseline across participants design, data revealed a functional relationship between the implementation of the intervention and an increase in the percentage of intervals that participants were on task. Overall, the participants' on-task behavior improved from a mean of 32% during baseline to 68% during intervention, with a proportionate percentage change of 118%. Although there is no widely accepted method for shaping, using percentile schedules as part of an intervention package appears to be a promising way to shape behavior.

使用带有百分位时间表的干预包来增加任务行为

改善任务行为可以让个人获得更多的学习机会，这对发育障碍的人尤其重要。目前的研究检查了干预包的功效，该干预包使用强化、反馈的百分位时间表和应用下限来改变标准以增加发育障碍儿童的任务行为。使用跨参与者设计的非并发多基线，数据揭示了干预的实施与参与者完成任务的间隔百分比增加之间的功能关系。总体而言，参与者的任务行为从基线期间的平均 32% 提高到干预期间的 68%，比例变化为 118%。
