Differential reinforcement of a target response is a necessary component of stimulus control transfer procedures. Recent research has further considered the timing (i.e., onset) of differential reinforcement of unprompted correct responding. To date, the onset of differential reinforcement has been inconsistently controlled in studies comparing skill acquisition programs for individuals with developmental disabilities. The current study serves as a systematic replication of prior comparative research to examine the effects of immediate and delayed differential reinforcement onset on the efficiency of acquisition for three individuals with developmental disabilities. The delayed onset of differential reinforcement required the fewest number of exposures to mastery per target across all comparisons. These findings failed to replicate those of prior research on differential reinforcement onset, possibly due to differences in participant characteristics, target tasks, or other required procedural modifications. Considerations for future research on differential reinforcement procedures in skill acquisition programs are described.
目标反应的差别强化是刺激控制转移程序的必要组成部分。最近的研究进一步考虑了无提示正确反应的差别强化的起始时间（即开始）。迄今为止，在比较发育障碍个体的技能习得程序的研究中，差别强化的起始时间一直没有得到一致的控制。本研究作为先前比较研究的系统复制，旨在检查即时和延迟差别强化起始对三个发育障碍个体习得效率的影响。在所有比较中，延迟的差别强化起始需要的每个目标的暴露次数最少。这些发现与先前关于差别强化起始的研究结果不一致，可能是由于参与者特征、目标任务或其他必要程序修改的差异所致。描述了未来关于技能习得计划中差别强化程序的研究的考虑因素。
