DESCRIPTION (provided by applicant): Autistic Spectrum Disorders (ASD) form a group of neuropsychiatric conditions whose core behavioral features include impairments in reciprocal social interaction, in communication, and repetitive, stereotyped, or restricted interests and behaviors. The importance of prosodic deficits in the adaptive communicative competence of speakers with ASD, as well as for a fuller understanding of the social disabilities central to these disorders is generally recognized; yet current studies are few in number and have significant methodological limitations. The objective of the proposed project is to detail prosodic deficits in young speakers with ASD through a series of experiments that address these disabilities and related areas of function. Key features of the project include: 1) the application of innovative technology. The study will apply computer-based speech and language technologies for quantifying expressive prosody, for computing dialogue structure, and for generating acoustically controlled speech stimuli for measuring receptive prosody; moreover, all experiments will be delivered via computer to insure consistency of stimuli and accuracy of recording responses; 2) broad coverage of the dimensions of prosody. All three functions of prosody, grammatical, pragmatic, and affective, will be addressed; expressive and receptive tasks are included; and both contextualized tasks (dialogue, story comprehension and memory) and decontextualized tasks (e.g., vocal affect recognition) will be used; 3) inclusion of neuropsychological assessment and classification methodologies to address within-group heterogeneity and obtain a detailed characterization of the groups; 4) inclusion of two comparison groups: children with typical development and those with Developmental Language Disorder; 5) inclusion of an experimental treatment program to enhance the prosodic abilities of speakers with ASD.

描述（由申请人提供）：自闭症谱系障碍 (ASD) 是一组神经精神疾病，其核心行为特征包括相互社交互动、沟通障碍以及重复、刻板或受限的兴趣和行为。人们普遍认识到韵律缺陷对于患有自闭症谱系障碍的人的适应性沟通能力以及更全面地理解这些疾病的核心社会障碍的重要性；然而目前的研究数量很少，并且具有显着的方法学局限性。拟议项目的目标是通过一系列解决这些残疾和相关功能领域的实验来详细说明患有自闭症谱系障碍的年轻说话者的韵律缺陷。该项目的主要特点包括：1）创新技术的应用。该研究将应用基于计算机的语音和语言技术来量化表达韵律、计算对话结构以及生成声学控制的语音刺激以测量接受韵律；此外，所有实验都将通过计算机进行，以确保刺激的一致性和记录反应的准确性； 2）韵律维度的广泛覆盖。韵律的所有三个功能：语法、实用和情感，都将得到解决；包括表达性和接受性任务；并且将使用情境化任务（对话、故事理解和记忆）和去情境化任务（例如声音情感识别）； 3）纳入神经心理学评估和分类方法，以解决组内异质性并获得组的详细特征； 4) 纳入两个对照组：典型发育儿童和发育性语言障碍儿童； 5) 纳入一项实验性治疗计划，以增强自闭症谱系障碍患者的韵律能力。
