通过考察特定语言障碍(SLI)儿童和语言匹配的非SLI儿童对数字标记和数字一致性的习得情况，对SLI儿童语法缺陷的三种解释，即缺失特征、表层记述和缺失一致进行了评价。数据由108名学龄前儿童的自发语言记录组成。数字标记使用了五个复数发展指数：在强制性语境中的使用百分比、词汇生产力、选择性、对比性和形态生产力。我们考察了数字一致的两个层面：动词和主语之间的传统一致，以及名词短语内部的新一致。结果表明，SLI儿童控制数字标记，与缺失特征假说和Surface账户的预测相反。另一方面，正如预测的那样，与对照组儿童相比，SLI儿童跨越子句边界的数字一致更加困难。仔细分析名词短语中的数字标记，可以发现两种截然不同的语境，即限定词+名词和量词+名词。SLI儿童对后者的理解比前者更困难，而对照组儿童在这两种背景下没有区分。句法和语义解释是作为解释选项来讨论的。
Three accounts of the grammatical deficits of children with specific language impairment (SLI), that is, Missing Feature, Surface Account, and Missing Agreement, were evaluated by examining children with SLI and language-matched non-SLI children’s acquisition of number marking and number agreement. The data consisted of spontaneous language transcripts from 108 preschool children. Number marking was evaluated using five indices of plural development: percent of use in obligatory contexts, lexical productivity, selectivity, contrastivity, and morphological productivity. Two levels of number agreement were examined: the traditional agreement between the verb and its subject, and a new measure of agreement within the noun phrase. The results indicated that children with SLI control number marking, counter to the predictions of the Missing Feature hypothesis and the Surface Account. On the other hand, as predicted, number agreement across clausal boundaries was more difficult for the children with SLI as compared to the children in the control group. A close analysis of number marking within the noun phrase revealed two distinctive contexts, determiner + noun versus quantifier + noun. Children with SLI had more difficulty with the latter than the former, whereas the two contexts were not differentiated for the control children. Syntactic and semantic explanations are discussed as interpretive options.
