目的：研究典型语言发育和特殊语言障碍（SLI）导致的语言发育迟缓的学龄儿童的唇读及其认知相关因素。方法：对42例语言发育正常儿童和20例特殊语言障碍儿童进行词汇水平唇读测试和一系列标准化的认知和语言测试。结果：与正常发育的同龄人相比，患有特殊语言障碍的儿童阅读能力较差。在正常发育儿童和特殊语言障碍儿童中，良好的语音技能与熟练的唇读有关。研究还发现，唇读与一些认知技能有关，比如短期记忆能力和语言运动技能。结论：特殊语言障碍患者的言语处理缺陷也延伸到视觉言语感知。唇读表现与语音技能有关。因此，患有特殊语言障碍的儿童读唇能力差可能与语音加工问题有关。
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.
