LONGITUDINAL TREATMENT EFFEXTS IN SLI CHILDREN

子项目4的目的是完成以下项目的纵向比较 72名儿童基于模仿和对话重铸的干预研究 有特殊语言障碍的人。这项研究考察的问题是 是否有最佳的发展语言水平来交付 对儿童启蒙和/或 语言目标的结构化模仿呈现。从一个 从交易的角度看，儿童使用特定语言的能力 学习这些不同类型的成人反应的障碍可能 随着孩子语言水平的变化而改变。我们之前的研究是关于 对话重铸和模仿干预的效果(Camarata， Nelson和Camarata，1994；Nelson et al.1996)是有限的，因为 向SLI儿童提供治疗，这些儿童是从相对狭窄的 发展语言水平(Brown阶段IV/V)。此子项目将 将我们之前对会话重铸的研究扩展到更多样化 语言水平并将衡量目标习得的普遍影响 关于语言结果(在家中和在家庭中的自发语言样本 诊所设置)。此外，就总体概念化而言， 计划项目(请参阅概述)，该子项目将解决 以下问题：考察语言与语言之间的潜在联系 成长和干预前措施(例如，发展语言水平 在入院时，标准化测试结果，包括干预前 理解程度)；以及评估实践的性质和范围 目标获取、泛化和维护所需的。

The purpose of sub-project 4 is to complete a longitudinal comparison of imitation based and conversational recast interventions in 72 children with specific language impairment. The issue examined in this study is whether there are optimal developmental language levels for delivering focused "conversational recast" responses to child initiations and/or for structured imitation presentation of language targets. From a transactional perspective, the ability of a child with specific language impairment to learn from these different types of adult responses may shift as the child's language level changes. Our previous studies of the effects of conversational recast and imitation interventions (Camarata, Nelson and Camarata, 1994; Nelson et al. 1996) were limited because the treatments were provided to SLI children selected from a relatively narrow developmental language level (Brown Stages IV/V). This sub-project will extend our previous research on conversational recast to more diverse language levels and will measure generalized impacts of target acquisition on language outcomes (spontaneous language samples at home and in the clinic settings). Additionally, in terms of the overall conceptualization of the program project (see overview), this sub-project will address the following issues: Examining the potential association between language growth and pre-intervention measures (e.g., developmental language level at intake, results of standardized tests, including pre-intervention levels of comprehension); and evaluating the nature and extend of practice required for target acquisition, and for generalization and maintenance.
