In a videotaped free-play session with a parent, autistic children were compared with mental-age matched Developmental Language Delay (DLD) children and with normally developing (ND) 2-year-olds in the use of communicative acts by parent and child. Groups were matched for language level. Autistic children had more incidents of no responses, produced less affirming, turn-taking vocalization, and gesture, and were less likely to initiate communication than other children. Parent groups differed only in a greater amount of initiating and use of imperatives by parents of autistic children. Few relations between parent behaviors and child behaviors were found. Nonresponses by all children were concentrated subsequent to parent imperatives and questions, but no group differences were found in the distribution of nonresponses to various parent communicative acts. Results are interpreted to support the hypothesis that autistic children's language can serve a number of useful functions but that their pattern of language functions differs from that of nonautistic language-impaired children and much younger normal children of similar language level.
在与家长进行的录像自由玩耍环节中，研究人员比较了自闭症儿童与心理年龄匹配的发育性语言迟缓（DLD）儿童以及正常发育（ND）的2岁儿童在亲子交流行为中的表现。各小组在语言水平上进行了匹配。与其他儿童相比，自闭症儿童无回应的情况更多，肯定性回应、轮流发声和手势较少，发起交流的可能性也较小。家长小组之间的差异仅在于自闭症儿童的家长发起和使用祈使句的频率更高。研究发现家长行为与儿童行为之间的关联很少。所有儿童的无回应情况都集中在家长发出祈使句和提问之后，但对各种家长交流行为的无回应分布在各小组之间未发现差异。研究结果支持了这样一种假设，即自闭症儿童的语言可以发挥多种有用功能，但其语言功能模式与非自闭症语言受损儿童以及语言水平相似的年幼正常儿童不同。
