We evaluated differential reinforcement of alternative behavior (DRA) plus prompting to increase peer-directed mands for preferred items using a picture exchange communication system (PECS). Two nonvocal individuals with autism participated. Independent mands with a peer increased with the implementation of DRA plus prompting for both participants. In addition, peers engaged in brief social interactions following the majority of mands for leisure items. These results suggest that teaching children to use PECS with peers may be one way to increase manding and social interactions in individuals with limited or no vocal repertoire.
我们评估了替代行为的差别强化（DRA）加上提示，以使用图片交换沟通系统（PECS）增加同伴指导的对喜好物品的需求。两名患有自闭症的非言语个体参与了研究。对于两名参与者，实施 DRA 加上提示后，同伴指导的独立需求增加了。此外，在大多数休闲物品的需求之后，同伴们会进行短暂的社交互动。这些结果表明，教孩子与同伴一起使用 PECS 可能是增加有限或没有言语表达能力的个体的需求和社交互动的一种方式。
