DESCRIPTION (provided by applicant): Children with specific language impairment (SLI) often show serious limitations in grammatical ability. A clearer understanding of the reasons for these limitations could lead to more accurate methods of diagnosis and more effective methods of treatment for these children. The purpose of the proposed project is to explore the possible bases of the serious grammatical limitations exhibited by children with SLI. To accomplish this general goal, the grammatical comprehension and production abilities of children with SLI will be examined across four languages, English, Italian, Finnish, and Hungarian. Data from these different languages will be used to assess the relative adequacy of three recent accounts of grammatical deficits in English-speaking children with SLI. Because the grammatical properties of Italian, Finnish, and Hungarian 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 children with SLI. Inclusion of these other languages will also permit a determination of whether problems attributed to the grammatical details of tense and agreement are being compounded by problems with grammatical aspect. The experimental procedures are also designed to identify problems in sentence formulation that may exacerbate any difficulty attributable to limited grammatical knowledge. Finally, through careful selection of the grammatical details to be studied, it will be possible to determine whether children with SLI who speak African American English have serious difficulties in the same areas of grammar that have been found most fragile in mainstream American Englishspeaking children with SLI. Such a finding could lead to a uniform theory of how language impairment might develop and persist among children acquiring English.

描述（由申请人提供）：有特殊语言障碍（SLI）的儿童通常表现出严重的语法能力限制。更清楚地了解这些限制的原因可能会导致更准确的诊断方法和更有效的治疗方法。该项目的目的是探索SLI儿童表现出的严重语法限制的可能基础。为了实现这一总体目标，SLI儿童的语法理解和生产能力将在四种语言，英语，意大利语，芬兰语和匈牙利语进行检查。来自这些不同语言的数据将被用来评估最近的三个帐户的语法缺陷在讲英语的SLI儿童的相对充分性。由于意大利语，芬兰语和匈牙利语的语法特性不同于英语的关键方式，他们提供了一个更清晰的视图的贡献的因素，在英语混淆，从而促进解释的数据从讲英语的儿童与SLI。将这些其他语言包括在内也将允许确定归因于时态和一致的语法细节的问题是否被语法方面的问题所复杂化。实验程序的目的也是为了确定在句子的制定，可能会加剧任何困难归因于有限的语法知识的问题。最后，通过仔细选择要研究的语法细节，可以确定说非裔美国英语的SLI儿童是否在相同的语法领域有严重的困难，这些语法领域在主流美国英语儿童中被发现是最脆弱的。这一发现可能会导致一个统一的理论，语言障碍可能会发展和持续在儿童学习英语。
