The present study evaluated the effects of classwide satiation and embedded reinforcement procedures on preschoolers' activity preferences during scheduled free-play periods. The goal of the study was to increase time allocation to originally nonpreferred, but important, activities (instructional zone, library, and science) while continuing to provide access to all free-play activities. The satiation intervention applied to preferred activities resulted in increased time allocation to the instructional and science activities, the customized embedded reinforcement interventions resulted in increased time allocation to all three target activities, and high levels of attendance to the instructional and library activities were maintained during follow-up observations. Implications for the design of preschool free-play periods are discussed.
本研究评估了全班性饱足和嵌入式强化程序对学龄前儿童在预定自由活动时间的活动偏好的影响。该研究的目标是增加对原本不喜欢但重要的活动（教学区、图书馆和科学活动）的时间分配，同时继续提供参与所有自由活动的机会。应用于偏好活动的饱足干预导致对教学和科学活动的时间分配增加，定制的嵌入式强化干预导致对所有三个目标活动的时间分配增加，并且在后续观察中维持了对教学和图书馆活动的高参与度。文中讨论了对学前自由活动时间设计的启示。
