The present study was designed to examine the effects of social stimulation on the joint attention behavior of 20 autistic children under 6 years of age, 20 receptive language-matched Down syndrome children, and 20 receptive language matched-normally-developing infants. Children's social and non-social engagement states were measured during two experimental play sessions and during free play with parent. For all groups, joint attention was increased when adult play behavior closely followed and was contingent on the behavior of the children; however, the autistic children were significantly less responsive to the experimental manipulation than control subjects. In contrast, the autistic children were no less responsive in terms of other forms of social engagement. Results are interpreted as supporting a model of joint attention deficits in autism that involves factors inherent to the disorder in transaction with social context.
本研究旨在考察社会刺激对20名6岁以下自闭症儿童、20名接受性语言匹配的唐氏综合征儿童以及20名接受性语言匹配的正常发育婴儿共同注意行为的影响。在两次实验性游戏环节以及与父母的自由游戏过程中，对儿童的社交和非社交参与状态进行了测量。对于所有组而言，当成人游戏行为紧密跟随并取决于儿童的行为时，共同注意会增加；然而，自闭症儿童对实验操作的反应明显低于对照组。相比之下，自闭症儿童在其他形式的社交参与方面反应并不低。研究结果被解释为支持自闭症共同注意缺陷模型，该模型涉及该障碍在与社会背景相互作用时所固有的因素。
