Purpose Auditory processing measures have been used in an attempt to understand the relationship between neurological mechanisms and autism spectrum disorder (ASD) symptomatology in school-age children. The focus of the current study was to understand neural auditory processing in 2- to 3-year-olds with ASD. Method Auditory processing measures (click auditory brainstem responses and speech-evoked frequency-following responses) were hypothesized to differ between typically developing children ( = 18) and children with ASD ( = 18). Auditory processing measures were hypothesized to relate to language development in children with ASD. Results The current study found limited differences in auditory processing measures between the two groups. No relationships were found between auditory processing measures and language development measures. Conclusions Future research is necessary to characterize auditory processing in toddlers with ASD. Longitudinal approaches should be considered when studying auditory processing in children with ASD in order to explore its developmental relationship with ASD symptomatology.
目的
听觉处理测量已被用于试图理解学龄儿童神经机制与自闭症谱系障碍（ASD）症状之间的关系。本研究的重点是了解2至3岁ASD儿童的神经听觉处理情况。方法：假设典型发育儿童（n = 18）和ASD儿童（n = 18）在听觉处理测量（点击听觉脑干反应和言语诱发频率跟随反应）上存在差异。假设听觉处理测量与ASD儿童的语言发展有关。结果：本研究发现两组在听觉处理测量上存在有限差异。未发现听觉处理测量与语言发展测量之间存在关联。结论：未来有必要开展研究以明确ASD幼儿的听觉处理特征。在研究ASD儿童的听觉处理时应考虑采用纵向研究方法，以探索其与ASD症状学的发育关系。
