虽然解释的研究，在年龄较大的儿童，青少年和成人自闭症患者的面部识别是复杂的事实，参与样本和采用的方法有很大的不同，但仍然有强有力的证据表明，即使任务的性能是不缺乏处理的特点。关于自闭症儿童的面部识别能力，我们所知甚少。本研究采用了一个规范化的人脸识别任务，以测量这种能力在102名幼儿孤独症，广泛性发育障碍（PDDNOS），和非PDD障碍（精神发育迟滞和语言障碍）匹配的实际年龄和非言语的心理年龄，并在子样本的51名儿童平均分为相同的三组匹配的实际年龄和言语的心理年龄。与其他非言语匹配和言语匹配组相比，自闭症组的面部识别存在明显缺陷。两个比较任务的表现没有发现显着差异时，言语能力得到充分控制。我们的结论是，自闭症儿童的面部识别缺陷不能归因于整体认知能力或任务要求。与对照组相比，面部识别和非语言智力之间的相关性较低，这表明自闭症患者的面部识别与一般认知能力的相关性较低。与我们的预期相反，患有PDDNOS的儿童没有表现出面部识别缺陷。
Although the interpretation of studies of face recognition in older children, adolescents, and adults with autism is complicated by the fact that participating samples and adopted methodologies vary significantly, there is nevertheless strong evidence indicating processing peculiarities even when task performance is not deficient. Much less is known about face recognition abilities in younger children with autism. This study employed a well-normed task of face recognition to measure this ability in 102 young children with autism, pervasive developmental disorder not otherwise specified (PDDNOS), and non-PDD disorders (mental retardation and language disorders) matched on chronological age and nonverbal mental age, and in a subsample of 51 children divided equally in the same three groups matched on chronological age and verbal mental age. There were pronounced deficits of face recognition in the autistic group relative to the other nonverbally matched and verbally matched groups. Performance on two comparison tasks did not reveal significant differences when verbal ability was adequately controlled. We concluded that young children with autism have face recognition deficits that cannot be attributed to overall cognitive abilities or task demands. In contrast to controls, there was a lower correlation between performance on face recognition and nonverbal intelligence, suggesting that in autism face recognition is less correlated with general cognitive capacity. Contrary to our expectation, children with PDDNOS did not show face recognition deficits.
