The present study addresses three main issues: First, it considers whether the syntax development of dysphasic preschoolers is adequately described as being a purely quantitative retardation or whether there are qualitative differences as well. Second, the suggestion put forward by Grimm (1987) that the syntactic deficits of dysphasic children result from deficient language processing strategies is further explored. Third, it asks whether the language deficits are related to specific structural and interactional aspects of the language input. We examined two groups of children with comparable levels of language development: 8 dysphasic children, ages 3:9 to 4:8 years, and 8 control children, ages 2:1 to 2:11 years, who showed normal language development. The empirical evidence suggested that the dysphasic children's syntax development was not only delayed but also deviant, and that the children's deviant syntax structures were the result of insufficient language processing and could not be traced back to structural characteristics of the sentences used by their mothers.
第一，它考虑发育性语言障碍学龄前儿童的句法发展是否仅被充分描述为纯粹的数量延迟，还是也存在质的差异。第二，进一步探讨了格林（1987）提出的发育性语言障碍儿童的句法缺陷源于语言处理策略不足的观点。第三，它询问语言缺陷是否与语言输入的特定结构和互动方面有关。我们考察了两组语言发展水平相当的儿童：8名发育性语言障碍儿童，年龄在3岁9个月至4岁8个月之间，以及8名对照儿童，年龄在2岁1个月至2岁11个月之间，这些对照儿童表现出正常的语言发展。实证证据表明，发育性语言障碍儿童的句法发展不仅延迟，而且异常，并且儿童异常的句法结构是语言处理不足的结果，无法追溯到其母亲使用的句子的结构特征。
