This study investigated autistic children's use of attention-directing gestures and language in three different interactive situations which varied in social context factors. These behaviors were videotaped and compared in autistic children (n = 15), children with developmental language delay (n = 14), matched on mental age and mean length of utterance (MLU), and MLU-matched young normal children (n = 13). Results supported the hypothesis that autistic children's attention-directing behavior would differ most from that of the other groups in spontaneous interactions. However, contrary to expectation, the autistic children did not produce more attention-directing behavior when a high degree of adult direction was provided. Overall, the autistic group used attention-directing behaviors less frequently than the other groups, and in the autistic group these behaviors varied less across social context factors. Results are interpreted in terms of their implications for language intervention programs with autistic children.
本研究调查了自闭症儿童在三种不同互动情境中使用吸引注意力的手势和语言的情况，这些情境在社会环境因素方面存在差异。对自闭症儿童（n = 15）、发育性语言迟缓儿童（n = 14，在心理年龄和平均语句长度（MLU）上进行匹配）以及MLU匹配的正常幼儿（n = 13）的这些行为进行了录像并比较。结果支持了这样的假设，即自闭症儿童在自发互动中吸引注意力的行为与其他组差异最大。然而，与预期相反，当提供高度的成人指导时，自闭症儿童并没有产生更多吸引注意力的行为。总体而言，自闭症组比其他组更少使用吸引注意力的行为，并且在自闭症组中，这些行为在不同社会环境因素中的变化较小。根据这些结果对自闭症儿童语言干预项目的意义进行了解释。
