One of the most consistently documented characteristics of children with specific language impairment (SLI) is difficulty in the acquisition of grammatical morphology. Current theories of SLI center of this deficit area; however, complete evaluation of available theories is difficult because data exist which are both consistent and inconsistent with current accounts. In order to fully evaluate available positions, and to construct more complete accounts, SLI children's performance on a wider range of linguistic skills must be appraised. The area of derivational morphology appears ideally suited to this challenge. Thus, the general aims of this proposal are to assess the acquisition of derivational morphology in children with SLI, to determine whether the acquisition of derivational forms is particularly challenging for children with SLI, and to apply the resulting developmental patterns to the evaluation of current accounts of the disorder. Two studies will be conducted. The first study involves a cross-sectional examination of the use of six derivational morphemes by SLI children and two typically developing groups, one equated to the SLI subjects on the basis age, and the other on the basis of language ability. The target derivational morphemes will be elicited via picture tasks involving real- and nonce-word items. Analysis of variance procedures will be used to analyze these data. The extent to which derivational morphemes are problematic for children with SLI relative to their age- and language- mates will be considered, and results will be interpreted in light of major accounts of SLI children's morphological deficits. In the second study, the development of derivational morphology in five of the SLI subjects from the first study will be tracked longitudinaily for a two- year period. Again, patterns of derivational form acquisition will be evaluated relative to current theoretical accounts of SLI.

患有此类疾病的儿童最一致记录的特征之一 特定语言障碍 (SLI) 是指难以习得 语法形态。当前 SLI 理论是这种赤字的中心 区域;然而，对现有理论的完整评估是困难的 因为存在与当前一致和不一致的数据 账户。为了充分评估可用职位，并构建 账目更完整，SLI孩子的表现范围更广 必须评估语言能力。衍生形态学领域 似乎非常适合这一挑战。因此，本次会议的总体目标 建议评估衍生形态学的获取 患有SLI的儿童，确定是否获得了衍生能力 对于患有 SLI 的儿童来说，表格尤其具有挑战性，并且应用 由此产生的发展模式对经常账户的评估 紊乱。将进行两项研究。第一项研究涉及 对六个派生语素的使用进行横断面检查 SLI 儿童和两个典型发展群体，其中一个相当于 SLI 科目以年龄为基础，另一个科目以语言能力为基础。 目标派生语素将通过图片任务引出 涉及真实词和随机词项。差异分析程序将 用于分析这些数据。 派生语素的程度 对于患有 SLI 的儿童来说，相对于他们的年龄和语言来说是有问题的 将考虑配偶，并根据以下因素解释结果 SLI 儿童形态缺陷的主要解释。 在第二个 研究，五种 SLI 中派生形态学的发展 第一项研究的受试者将被纵向追踪两次 年期间。同样，派生形式习得的模式将是 相对于当前 SLI 的理论描述进行评估。
