目的本研究的第一个目的是探讨学龄前听力损失儿童（CHL）相对于年龄和语言匹配的对照组的形态句法产生的差异。第二个目的是探索将两个长期存在的关于特定语言障碍儿童形态句法缺陷的理论解释扩展到学龄前儿童的可能性。方法本研究通过对18名学龄前儿童的会话语言样本进行分析，并与年龄匹配的儿童进行比较，来描述Brown语法词素不准确产出的准确性和类型（±3个月，n= 18）和语言匹配组（表达性语言子测试±1个原始得分点，n= 18）。年龄范围为45至62个月。比较各组的性能。此外，生产准确性CHL的词素不同的紧张和持续时间进行了比较，以评估扩展的理论帐户的儿童与特定的语言障碍CHL.ResultsCHL表现出特别的困难与形态句法相对于其他方面的语言的有效性。此外，还观察到各组之间在准确性和不准确制作类型方面的差异。最后，一个统一的方法来解释在CHL的morphosyntax弱点是更合适的语言或感知的唯一approach.ConclusionsTaken在一起，本研究的结果支持一个统一的理论帐户的morphosyntax弱点在CHL中，紧张和持续时间的语素发挥作用，在morphosyntax生产的准确性，更强大的作用，紧张比持续时间。
PurposeThe first aim of this study was to explore differences in profiles of morphosyntax production of preschool children with hearing loss (CHL) relative to age- and language-matched comparison groups. The second aim was to explore the potential of extending 2 long-standing theoretical accounts of morphosyntax weakness in children with specific language impairment to preschool CHL.MethodThis study examined conversational language samples to describe the accuracy and type of inaccurate productions of Brown's grammatical morphemes in 18 preschool CHL as compared with an age-matched group (±3 months,n= 18) and a language-matched group (±1 raw score point on an expressive language subtest,n= 18). Age ranged from 45 to 62 months. Performance across groups was compared. In addition, production accuracy of CHL on morphemes that varied by tense and duration was compared to assess the validity of extending theoretical accounts of children with specific language impairment to CHL.ResultsCHL exhibited particular difficulty with morphosyntax relative to other aspects of language. In addition, differences across groups on accuracy and type of inaccurate productions were observed. Finally, a unified approach to explaining morphosyntax weakness in CHL was more appropriate than a linguistic- or perceptual-only approach.ConclusionsTaken together, the findings of this study support a unified theoretical account of morphosyntax weakness in CHL in which both tense and duration of morphemes play a role in morphosyntax production accuracy, with a more robust role for tense than duration.
