Engaging in spontaneous social exchanges is a central skill deficit of children with autism, and one that is often difficult to remediate. The 3 boys (ages 4, 4, and 5 years) who participated in this study had acquired small verbal repertoires, but typically spoke only when answering questions or requesting preferred edible items or toys, and did not converse with a familiar teacher during baseline. During teaching, textual cues ("Look" and "Watch me") were embedded in the youngsters' photographic activity schedules; after learning to use the scripts, the children's verbal elaborations and unscripted interactions increased and were maintained when a new recipient of interaction was introduced. After scripts were faded, unscripted interactions not only continued but also generalized to different activities that had not been the topic of teaching. The script-fading procedure enabled children with autism to converse with adults, to benefit from adults' language models, and to engage in language practice that contributes to fluency.
参与自发的社交交流是自闭症儿童核心的技能缺陷,而且往往难以纠正。参与本研究的3名男孩(年龄分别为4岁、4岁和5岁)已经掌握了少量的语言技能,但通常只在回答问题或索要喜欢的食物或玩具时才说话,在基线期与熟悉的教师也不交谈。在教学过程中,文本提示(“看”和“看着我”)被嵌入到孩子们的照片活动时间表中;在学会使用这些脚本后,孩子们的语言阐述和非脚本化互动增加了,并且在引入新的互动对象时得以保持。在脚本淡出后,非脚本化互动不仅持续存在,还推广到了未曾作为教学主题的不同活动中。脚本淡出程序使自闭症儿童能够与成年人交谈,受益于成年人的语言模式,并参与有助于提高流利度的语言练习。
