DESCRIPTION (provided by applicant): The objective of this project is to develop and field-test prototype software for a research-based vocabulary development program featuring a combined lexical-cognitive approach to noun acquisition. The target population for the curriculum will be 3-8 year old children with Autism Spectrum Disorders (ASD), as well as a broad range of other children with language disorders, with language function in the range of 2-5 years. The curriculum will use a core noun vocabulary in training activities de- signed to address four interrelated goals: (a) train a basic noun vocabulary using both fast and slow mapping strategies; (b) enrich the semantic features of lexical entries by associating them with functional and/or descriptive information; (c) enhance lexical organization by using the core vocabulary in a series of categorization activities; and (d) expand paradigmatic schemas with training that associates basic level nouns with paradigmatically associated concepts. A subset of the curriculum was developed in Phase I and used in iterative testing with subjects in the target populations. It was found that even low language functioning children with ASD were able to use the prototype materials as intended and acquire or demonstrate knowledge of fast mapping, the vocabulary items, their categories, and their semantic associations. In Phase II the knowledge gained in Phase I will be used to improve and expand the curriculum into a prototype that covers 220 Target Nouns (110 associated pairs) with at least 10 superordinate noun categories. The prototype will include a unique integrated expert curriculum control system that includes probe tests to establish appropriate entry points into the curriculum, and will provide highly individualized and efficient language instruction in appropriate activities with proper instructional support. The prototype will be used in a 12-week field test in a public school distrit to evaluate its effectiveness when used by children with ASD and language impairments under natural conditions. Dependent measures will include pre- and post-intervention measures of receptive and expressive language status. PUBLIC HEALTH RELEVANCE: Impaired language is recognized as one of the hallmarks of Autism Spectrum Disorder (ASD). Despite extensive incidental exposure to language, many children with ASD have a markedly limited vocabulary and are clearly in need of formal remediation. The goal of this project is to develop a curriculum and prototype software for a research-based vocabulary development program featuring a combined lexical-cognitive approach to noun acquisition. The curriculum will focus on helping children to develop the learning processes necessary for efficient lexical acquisition and organization, and on laying the groundwork for a rich and semantically well organized conceptual framework. This will provide a cost effective means to promote early language and cognitive development in children with ASD as well as a broad range of other children with language disorders.

描述（由申请人提供）：本项目的目标是开发和现场测试原型软件的研究为基础的词汇发展计划，具有词汇认知相结合的方法来获得名词。该课程的目标人群将是3-8岁自闭症谱系障碍（ASD）儿童，以及语言功能在2-5岁范围内的其他语言障碍儿童。该课程将在设计的训练活动中使用核心名词词汇，以实现四个相互关联的目标：（a）使用快速和慢速映射策略训练基本名词词汇;（B）通过将词条与功能和/或描述性信息相关联来丰富词条的语义特征;（c）通过在一系列分类活动中使用核心词汇来增强词汇组织;（d）通过在一系列分类活动中使用核心词汇来增强词汇组织。以及（d）通过将基本水平名词与聚合相关概念相关联的训练来扩展聚合图式。在第一阶段开发了课程的一个子集，并用于目标人群中受试者的迭代测试。结果发现，即使是低语言功能的自闭症儿童能够使用的原型材料的意图，并获得或展示知识的快速映射，词汇项目，它们的类别，和它们的语义协会。在第二阶段，在第一阶段获得的知识将用于改进和扩展课程，使其成为一个原型，涵盖220个目标名词（110个相关对），至少有10个上位名词类别。该原型将包括一个独特的综合专家课程控制系统，其中包括探索测试，以确定课程的适当切入点，并将在适当的活动中提供高度个性化和有效的语言教学，并提供适当的教学支持。该原型将在公立学校进行为期12周的实地测试，以评估其在自然条件下用于ASD和语言障碍儿童时的有效性。依赖性措施将包括接受性和表达性语言状态的干预前和干预后措施。 公共卫生相关性：语言障碍被认为是自闭症谱系障碍（ASD）的标志之一。尽管广泛的偶然接触语言，许多ASD儿童的词汇量明显有限，显然需要正式的补救。本项目的目标是为一个以研究为基础的词汇发展项目开发一个课程和原型软件，该项目以词汇认知结合的方法来获得名词。该课程将侧重于帮助儿童发展有效的词汇习得和组织所需的学习过程，并为丰富和语义组织良好的概念框架奠定基础。这将提供一种具有成本效益的方法，以促进ASD儿童以及其他各种语言障碍儿童的早期语言和认知发展。
