本文提供的证据支持这一假设，即发育性语言障碍是由于在标记特定类别的语言特征方面的缺陷所致。数据表明，这种缺陷不是知觉问题或表示等级关系的一般认知问题的结果，而是一个特定的语言问题。此外，这并不是一种同样影响语言所有部分的缺陷。句法语义特征受到影响，而其他一些语言过程，如简单句中的主位关系，则没有受到影响。由于没有这些特征，语素规则和与句法特征相匹配的规则也不存在。语言的所有表现形式--自发言语、语法判断、重复和写作--都存在同样的错误，这一事实支持了这一假设，即缺陷存在于潜在的语法中，而不仅仅是表现上的问题。来自各种功能的数据(包括数字、每个……
This article provides evidence that supports the hypothesis that developmental dysphasia results from a deficit in marking a specific class of linguistic features. The data show that this deficit is not the result of a perceptual problem or any general cognitive problem in representing hierarchical relationships, but rather appears to be a specifically linguistic problem. Moreover, it is not a deficit that affects all parts of language equally. Syntacficosemantic features are affected, whereas some other language processes, like thematic relations in simple sentences, are unimpaired. Because these features are absent, morphophonemic rules and rules that match features in the syntax are also absent. The fact that the same errors are found in all manifestations of language-spontaneous speech, grammatical judgment, repetition, and writing-supports the hypothesis that the deficit is in the underlying grammar rather than merely a problem of performance. Data from a wide range of features (including number, per...
