目的：描述和比较学龄期儿童听觉处理障碍（APD）和特定语言障碍（SLI）相关的行为特征。方法：本横断面观察性研究的参与者为64名儿童（平均年龄10.1岁），通过临床医生转诊招募。35名参与者被临床诊断为APD，29名参与者正在接受语言障碍服务。参与者完成了18项行为测量，包括口语、听觉处理、阅读、记忆和运动速度。响应用于将儿童分类为受APD影响/未受APD影响，以及受SLI影响/未受SLI影响。比较了有和没有APD诊断的儿童之间，以及分配到APD/非APD和SLI/非SLI组的儿童之间。临床状态和测试为基础的分类之间的协议也reported.Results：有和没有APD的临床诊断的儿童之间没有组的平均差异。APD组和非APD组儿童在立方体设计和阅读流畅性方面的组间差异显著; SLI组和非SLI组儿童在非词重复、空间工作记忆和两种听觉加工测验方面的组间差异显著。虽然组平均差异被发现，他们很难解释在当前的theories.Learning outcomes：读者将能够：（1）描述SLI儿童和APD儿童之间的相似性和差异，（2）讨论SLI和APD重叠的行为特征所带来的评估问题。(C)2011 Elsevier Inc.

Purpose: To describe and compare behavioral profiles associated with auditory processing disorder (APD) and specific language impairment (SLI) in school-age children.Method: The participants in this cross-sectional observational study were 64 children (mean age 10.1 years) recruited through clinician referrals. Thirty-five participants had a clinical diagnosis of APD and 29 were receiving services for language impairment. Participants completed 18 behavioral measures of spoken language, auditory processing, reading, memory, and motor speed. Responses were used to classify children as affected/not affected with APD, and affected/not affected with SLI. Comparisons were made between children with and without an APD diagnosis, and between children assigned to the APD/not APD and SLI/not SLI groups. Agreement between clinical status and test-based classifications is also reported.Results: There were no group mean differences between children with and without a clinical diagnosis of APD. Group mean differences on Cube Design and reading fluency were observed for children classified as APD/not APD: and group mean differences on nonword repetition, spatial working memory, and two auditory processing tests were observed for children classified as SLI/not SLI.Conclusions: The behavioral profiles of children with APD and SLI were very similar. Although group mean differences were found, they were difficult to interpret in terms of current theories.Learning outcomes: The reader will be able to: (1) describe similarities and differences found between children with SLI and children with APD and (2) discuss assessment problems posed by overlapping behavioral characteristics of SLI and APD.
