A randomized control trial comparing two social-communication interventions in young children with autism examined far-transfer of the use of picture exchange to communicate. Thirty-six children were randomly assigned to one of two treatment conditions, one of which was the Picture Exchange Communication System (PECS). All children had access to picture symbols during assessments. Post-treatment measurement of the number of picture exchanges in a far-transfer, assessment context favored the PECS intervention. These findings were interpreted as support for the hypothesis that the PECS curriculum can successfully teach a generalized means of showing coordinated attention to object and person without requiring eye contact to children with ASD.
一项针对自闭症幼儿的两种社交沟通干预措施的随机对照试验，考察了图片交换在沟通中的远迁移应用。36 名儿童被随机分配到两种治疗条件之一，其中一种是图片交换沟通系统（PECS）。所有儿童在评估期间都可以使用图片符号。在远迁移评估情境中，治疗后的图片交换数量测量结果有利于 PECS 干预。这些发现被解释为支持以下假设的证据，即 PECS 课程可以成功地教授自闭症儿童一种无需眼神接触即可协调地指向物体和人的通用注意力展示方式。
