PURPOSE
Lipreading and its cognitive correlates were studied in school-age children with typical language development and delayed language development due to specific language impairment (SLI).
METHOD
Forty-two children with typical language development and 20 children with SLI were tested by using a word-level lipreading test and an extensive battery of standardized cognitive and linguistic tests.
RESULTS
Children with SLI were poorer lipreaders than their typically developing peers. Good phonological skills were associated with skilled lipreading in both typically developing children and in children with SLI. Lipreading was also found to correlate with several cognitive skills, for example, short-term memory capacity and verbal motor skills.
CONCLUSIONS
Speech processing deficits in SLI extend also to the perception of visual speech. Lipreading performance was associated with phonological skills. Poor lipreading in children with SLI may be, thus, related to problems in phonological processing.
目的
研究具有典型语言发展能力的学龄儿童以及因特定语言障碍（SLI）导致语言发展迟缓的儿童的唇读及其认知关联。
方法
使用词汇水平的唇读测试以及一系列广泛的标准化认知和语言测试，对42名具有典型语言发展能力的儿童和20名患有SLI的儿童进行测试。
结果
患有SLI的儿童唇读能力比其具有典型语言发展能力的同龄人差。良好的语音技能与具有典型语言发展能力的儿童以及患有SLI的儿童的熟练唇读能力相关。还发现唇读与多种认知技能相关，例如短期记忆能力和言语运动技能。
结论
SLI中的言语处理缺陷也扩展到视觉言语感知。唇读表现与语音技能相关。因此，患有SLI的儿童唇读能力差可能与语音处理问题有关。
