MORPHOLOGICAL DEFICITS IN SPECIFIC LANGUAGE IMPAIRMENT

有特殊语言障碍的儿童通常表现出特别的 语法形态学的使用受到严重限制。 这些 困难包括与过去时态等绑定语素的问题， 第三人称单数词形变化，以及冠词等虚词 助动词。 本项目的目的是探索 这些语法语素限制的可能基础，并检查 这种限制如何可能阻碍这些儿童的其他方面的 语言发展 为了实现这一总体目标，特别是语言障碍（SLI） 儿童对语法词素的理解和产生， 研究了四种不同的语言：英语，希伯来语，意大利语， 瑞典人 来自这些不同语言的数据将用于评估 三个最近的帐户的英语SLI的相对充分 儿童的形态学问题。 因为形态学 这些语言的特性与英语的特性在关键方面有所不同 他们提供了一个更清晰的观点，这些因素的贡献， 用英语混淆，从而便于解释数据 从讲英语的SLI儿童那里获得。 包含这些 其他语言也将允许更强的测试， 词序与词法缺陷有关。 了解 SLI儿童的形态学问题的来源及其在SLI儿童中的作用 问题发挥在其他领域的语言应导致更适当的 这些孩子的治疗方法。

Children with specific language impairment often show an especially serious limitation in the use of grammatical morphology. These difficulties include problems with bound morphemes such as past tense and third person singular inflections, and function words such as articles and auxiliary verbs. The purpose of this project is to explore the possible bases of these grammatical morpheme limitations, and to examine how such limitations may hinder other aspects of these children's language development. To accomplish this general goal, specifically language-impaired (SLI) children's comprehension and production of grammatical morphemes will be examined across four different languages: English, Hebrew, Italian, and Swedish. Data from these different languages will be used to assess the relative adequacy of three recent accounts of English-speaking SLI children's problems with morphology. Because the morphological properties of these languages differ from those of English in critical ways, they offer a clearer view of the contribution of factors that are confounded in English, thereby facilitating interpretation of the data obtained from the English-speaking SLI children. Inclusion of these other languages will also permit a stronger test of whether problems in word order are related to deficits in morphology. An understanding of the source of SLI children's problems with morphology and the role these problems play in other areas of language should lead to more appropriate treatment procedures for these children.
