Recent studies suggest that morphosyntactic difficulties may result from prosodic problems. We therefore address the interface between inflectional morphology and prosody in typically developing children (TD) and children with SLI by testing whether these groups are sensitive to prosodic constraints that guide plural formation in German. A plural elicitation task was designed consisting of 60 words and 20 pseudowords. The performance of 14 German-speaking children with SLI (mean age 7.5) was compared to age-matched controls and to younger children matched for productive vocabulary. TD children performed significantly better than children with SLI. Error analyses revealed that children with SLI produced more forms that did not meet the optimal shape of a noun plural. Beyond the fact that children with SLI have deficits in plural marking, the findings suggest that they also show reduced sensitivity to prosodic requirements. In other words, the prosodic structure of inflected words seems to be vulnerable in children with SLI.
近期研究表明，形态句法困难可能源于韵律问题。因此，我们通过测试典型发育儿童（TD）和特定语言障碍（SLI）儿童是否对指导德语复数形式构成的韵律限制敏感，来探讨屈折形态与韵律之间的关系。设计了一个复数引出任务，包括60个单词和20个伪词。将14名说德语的SLI儿童（平均年龄7.5岁）的表现与年龄匹配的对照组以及生产性词汇匹配的年幼儿童进行比较。TD儿童的表现明显优于SLI儿童。错误分析表明，SLI儿童产生了更多不符合名词复数最佳形式的形式。除了SLI儿童在复数标记方面存在缺陷这一事实外，研究结果还表明，他们对韵律要求的敏感度也较低。换句话说，屈折词的韵律结构在SLI儿童中似乎较为脆弱。
