Echoics are a critical target of language intervention for children with autism, because a well-established echoic repertoire on the part of the child allows the clinician to use vocal modeling as a flexible, low-effort prompting procedure during teaching. In this study, we implemented a chaining procedure to increase the complexity of echoics in 2 children with autism and 1 child with developmental delay. The procedure was effective for all 3 participants, and gains were maintained after treatment was withdrawn in most cases.
仿效言语是自闭症儿童语言干预的一个关键目标,因为儿童具备完善的仿效言语能力可以使临床医生在教学过程中使用声音模仿作为一种灵活、低投入的提示程序。在这项研究中,我们采用连锁程序来增加 3 名自闭症儿童和 1 名发育迟缓儿童的仿效言语复杂性。该程序对所有 3 名参与者均有效,并且在大多数情况下,治疗停止后仍能保持效果。
