This systematic replication was designed to teach nonvocal children with autism to mand for missing items using an Augmentative Alternative Communication (AAC) system. Consistent with Rodriguez et al. (2017) and Wójcik et al. (2020), we used the interrupted chain procedure with EO-present and EO-absent trials. Consistent with Wójcik et al., 2020, we used sufficient exemplar training and activity schedules to establish manding for missing items. Participants were three children with autism, and the design was a nonconcurrent multiple-baseline design across participants. Following training, all participants requested the missing items during EO-present trials correctly and refrained from making requests during EO-absent trials, suggesting that requesting using the AAC system was established as a verbal operant controlled by the appropriate EO, hence, was established as a mand. Correct requesting behavior transferred to new tasks, across skill domains, across people, to new settings, and across time.

教自闭症无声儿童索要遗失物品

这种系统的复制旨在教自闭症的非语言儿童使用增强替代通信 (AAC) 系统来要求丢失的项目。与罗德里格斯等人一致。(2017) 和 Wójcik 等人。（2020 年），我们使用了 EO 存在和 EO 不存在试验的中断链程序。与 Wójcik et al., 2020 一致，我们使用了足够的示例培训和活动时间表来建立对缺失物品的要求。参与者是三名自闭症儿童，该设计是跨参与者的非并发多基线设计。培训结束后，所有参与者在 EO 存在的试验中正确地请求了缺失的项目，并在没有 EO 的试验中避免提出请求，这表明使用 AAC 系统的请求被建立为由适当的 EO 控制的口头操作，因此，被确立为一项要求。正确的请求行为转移到新任务、跨技能领域、跨人员、新环境和跨时间。
