A sample of 74 young autistic children was selected and defined by direct observation of specific behaviors and clinical assessment of the presence or absence of associated pathological conditions. Retrospective developmental data on these children and 38 age-matched normal children were gathered by means of a written inventory completed by the parents when the children were relatively young (mean age less than 4 years). The autistic children were reported to have had significant delays in the development of motor abilities, speech, communication, comprehension, and, to a lesser extent, perception during their 1st and 2nd years.
选取了74名患有自闭症的幼儿样本，通过直接观察特定行为以及对相关病理状况的有无进行临床评估来界定。这些儿童以及38名年龄匹配的正常儿童的回顾性发育数据，是通过家长在孩子相对年幼时（平均年龄小于4岁）填写的书面调查问卷收集的。据报告，自闭症儿童在其1岁和2岁时，运动能力、语言、沟通、理解能力以及在较小程度上的感知能力发展均出现了显著延迟。
