目的探讨语言和语音障碍儿童(包括儿童言语失用症)的语言负荷与发音变异性之间的关系。方法选取48 ~ 92月龄儿童46例,包括语音障碍、发展性语言障碍(又称特异性语言障碍)、儿童语言失用症和典型发育儿童。儿童先模仿(低语言负荷任务),然后检索(高语言负荷任务)代理+动作短语。使用语音运动学对发音变异性进行量化。我们评估了语言状态和言语状态(正常与受损)与发音变异性的关系。结果与模仿任务相比,所有儿童在检索任务中都表现出更高的发音变异性。然而,只有有语言障碍的孩子在检索任务中表现出不成比例的发音变异性,相对于具有典型语言技能的同龄人。结论高水平语言加工对低水平言语运动控制的影响更大,且语言的中介作用强于言语技能。
PurposeThe aim of the study was to investigate the relationship between language load and articulatory variability in children with language and speech sound disorders, including childhood apraxia of speech.MethodForty-six children, ages 48–92 months, participated in the current study, including children with speech sound disorder, developmental language disorder (aka specific language impairment), childhood apraxia of speech, and typical development. Children imitated (low language load task) then retrieved (high language load task) agent + action phrases. Articulatory variability was quantified using speech kinematics. We assessed language status and speech status (typical vs. impaired) in relation to articulatory variability.ResultsAll children showed increased articulatory variability in the retrieval task compared with the imitation task. However, only children with language impairment showed a disproportionate increase in articulatory variability in the retrieval task relative to peers with typical language skills.ConclusionHigher-level language processes affect lower-level speech motor control processes, and this relationship appears to be more strongly mediated by language than speech skill.
