We replicated and extended research on incorporating naturalistic discriminative stimuli into schedule thinning following functional communication training with three boys with autism spectrum disorder who engaged in severe behavior. Comparing naturalistic to arbitrary discriminative stimuli, two participants demonstrated differentiated communication in fewer sessions when arbitrary stimuli were used, while the third participant mastered the discriminations in a comparable number of sessions. Although previous research has demonstrated success in rapidly thinning the schedule with arbitrary stimuli, we extended this line of research by evaluating the extent to which differentiated communication would maintain during rapid schedule thinning in both naturalistic and arbitrary conditions. Two participants' communication remained differentiated, and in both conditions, during rapid schedule thinning. However, neither discrimination maintained for the third participant. Results are discussed in terms of the existing literature and directions for future research.

功能交流训练后的稀疏时间表中自然主义和任意歧视性刺激的比较

我们复制并扩展了与三名患有严重行为的自闭症谱系障碍男孩进行功能性交流训练后，将自然判别刺激纳入日程稀疏的研究，并对此进行了扩展。比较自然主义和任意歧视性刺激，当使用任意刺激时，两名参与者在较少的会话中表现出差异化的交流，而第三名参与者在相当数量的会话中掌握了区别。尽管先前的研究已经证明了在通过任意刺激快速精简计划方面取得了成功，但我们通过评估在自然主义和任意条件下快速精简计划期间差异通信将维持的程度，扩展了这一研究范围。两位参与者的交流仍然有所不同，并且在这两种情况下，都可以快速进行计划稀疏。但是，对第三位参与者都没有歧视。根据现有文献和未来研究方向讨论了结果。
