DESCRIPTION (provided by applicant): Spoken communication is more than merely producing and perceiving words in a sentence frame; how the utterance is produced (i.e. prosody) can dramatically alter the intended message. Adult linguistic prosody has a wide variety of accent and phrasing contrasts, yet our knowledge of the developmental trajectory of prosodic control remains incomplete. The overarching goal of the proposed work is to uncover children's emerging knowledge of the grammar of spoken prosody (i.e. what its contrastive categories are, how children signal them in production and recognize them in perception, and which communicative contexts they use them in), and to shed light on how this knowledge emerges into mastery of the adult inventory. A major limitation of previous work is the reliance on imitation and production tasks that may be confounded by the child's under-developed vocal motor system. In this proposal, we focus on developing an innovative methodology and stimuli for assessing prosodic control in a cross-sectional study of 30 children from three age groups 4, 7 and 11 years old. This project is aimed at developing and validating the Prosodic Marionette, a novel experimental tool that enables tracking of the child's ability to use prosodic knowledge despite potentially immature motor control of the vocal apparatus (Specific Aim 1); assessing children's knowledge of a broader range of prosodic contrasts and difficulty levels than previously studied (Specific Aim 2), and directly comparing prosodic abilities of children across age groups in both imitation and Prosodic Marionette tasks (Specific Aim 3). In addition to providing benchmarks for typical prosodic development, the proposed work has broader implications for understanding and remediating impairments of prosody, which have adverse consequences for linguistic, cognitive and social development. PUBLIC HEALTH RELEVANCE: The overarching goal of the proposed work is to uncover children's emerging knowledge of the grammar of spoken prosody and to shed light on how this knowledge emerges into mastery of the adult inventory. In this proposal, we focus on developing a novel methodology and stimuli for assessing prosodic control in a cross-sectional study of 30 children from three age groups 4, 7 and 11 years old.

描述(申请人提供)：口语交流不仅仅是产生和感知一个句子框架中的单词；如何产生话语(即韵律)可以极大地改变预期的信息。成人语言韵律有各种各样的口音和短语对比，但我们对韵律控制的发展轨迹的了解仍然不完整。这项拟议工作的总体目标是揭示儿童对口语韵律语法的新兴知识(即，它的对比范畴是什么，儿童如何在产出中发出信号并在感知中识别它们，以及他们在哪些交际语境中使用它们)，并阐明这些知识是如何形成对成人清单的掌握的。以前工作的一个主要局限性是依赖于模仿和生产任务，而这些任务可能会被孩子不发达的发声运动系统所混淆。在这项提案中，我们专注于开发一种创新的方法和刺激来评估韵律控制，这是一项横断面研究，研究对象为来自4、7和11岁三个年龄组的30名儿童。本项目旨在开发和验证韵律木偶，这是一种新的实验工具，能够跟踪儿童使用韵律知识的能力，尽管儿童对发声器官的运动控制可能不成熟(具体目标1)；评估儿童对比以前研究的更广泛的韵律对比和难度水平的知识(具体目标2)，并直接比较不同年龄组儿童在模仿和韵律木偶任务中的韵律能力(具体目标3)。除了为典型的韵律发展提供基准外，拟议的工作还对理解和纠正韵律障碍具有更广泛的影响，这些障碍对语言、认知和社会发展具有不利影响。 公共卫生相关性：拟议工作的首要目标是揭示儿童对口语韵律语法的新兴知识，并阐明这些知识是如何形成对成人清单的掌握的。在这项提案中，我们专注于开发一种新的方法和刺激来评估韵律控制，这是一项横断面研究，研究对象为来自4、7和11岁三个年龄组的30名儿童。
