本研究旨在评估自闭症儿童早期发声行为的性质。最近的方法和概念的进步，在婴儿言语前发声的研究被用来提供一个详细的检查的声音行为的年轻言语前儿童自闭症和比较儿童发育迟缓。结果显示，自闭症儿童在表达格式良好的音节方面没有困难（即，典型的咿呀学语）。然而，患有自闭症的儿童确实表现出声音质量的显著损害（即，非典型发声）。具体来说，自闭症儿童产生了更大比例的音节与非典型发声比比较儿童。与先前的报告一致，自闭症儿童也表现出联合注意力行为的缺陷。此外，自闭症儿童的发声行为的相似性似乎独立于联合注意技能的个体差异，这表明可能需要一个多过程模型来描述自闭症儿童的早期社会沟通障碍。数据进行了讨论，在其对未来的理论和应用研究，包括努力提高早期诊断程序的特异性方面的影响。
This study was designed to evaluate the nature of early vocal behaviors in young children with autism. Recent methodological and conceptual advances in the study of infant preverbal vocalizations were used to provide a detailed examination of the vocal behavior of young preverbal children with autism and comparison children with developmental delays. Results revealed that children with autism did not have difficulty with the expression of well-formed syllables (i.e., canonical babbling). However, children with autism did display significant impairments in vocal quality (i.e., atypical phonation). Specifically, autistic children produced a greater proportion of syllables with atypical phonation than did comparison children. Consistent with prior reports, the children with autism also displayed a deficit in joint attention behaviors. Furthermore, the atypicalities in the vocal behavior of children with autism appeared to be independent of individual differences in joint attention skill, suggesting that a multiple process model may be needed to describe early social-communication impairments in children with autism. Data are discussed in terms of their implications for future theoretical and applied research, including efforts to enhance the specificity of early diagnostic procedures.
