College readiness and career opportunities are highly dependent on young adults' reading proficiency. Yet, recent data indicate that almost two-thirds of tested students, including many students with dyslexia, do not possess the fundamental skills that are required to successfully master college-level reading material. Prosody, defined as linguistically relevant fluctuations in intonation, stress and timing, is an essential but underappreciated aspect of spoken language and reading. Humans vary in their sensitivity to the prosodic structure of speech, and there appears to be a strong link to individual differences in reading skills. With the support of the Integrative Strategies in Neural and Cognitive Systems program, this project will take bold steps towards investigating the biology and function of prosody with a creative array of approaches and research settings. With the first-ever dataset of its kind, the project intends to make critical progress towards integrating knowledge from a large population sample about the neurobiological basis of prosody across methods and levels (genetics, neuroimaging, and behavioral task performance). Beyond scientific advancement, the activities outlined in the proposed project will allow the research team to contribute to improving STEM education and educator development, addressing neurodevelopmental disorders such as dyslexia, increasing public engagement with science and technology, and enhancing big-data partnerships across academic sites.The underlying biology of prosody is poorly understood at the neural and genetic level, despite its important function in humans' communication skills. Innovative combinations of multi-disciplinary approaches for novel data collection in large samples and use of existing large-scale resources are needed to yield significant knowledge of the biology and function of prosody. The first aim of this proposal will include a series of studies using a combination of EEG, eye tracking and standardized behavioral tasks to explore the time-dynamic processes of attending to prosodic cues in ecologically valid situations of speech perception and reading, and to examine the contribution of prosody sensitivity to individual differences in reading. The second aim will be a genome-wide association study of prosodic sensitivity and will be conducted through a diverse sample of individuals recruited online throughout the United States and in-person in the Middle Tennessee area in local community and educational settings. Cutting-edge genomic methodologies (PrediXcan and Gene Set Enrichment analysis) will be used to identify the genetic markers and novel neural endophenotypes (imputed gene expression in brain tissue) that give rise to individual differences in prosody. This series of studies builds essential groundwork for future planned studies that seek to disentangle shared versus separate genetic architecture of prosody and other aspects of language function and could reveal transformative knowledge about the biological mechanisms driving individual differences in reading and language skill. The collaborative research project leverages the team's diverse backgrounds in Cognitive Neuroscience, Psycholinguistics, Communication Disorders, and Human Genetics.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

大学入学准备和就业机会在很大程度上取决于年轻人的阅读能力。然而，最近的数据表明，几乎三分之二的受测学生，包括许多阅读困难的学生，不具备成功掌握大学水平阅读材料所需的基本技能。韵律，被定义为语调、重音和时间上与语言相关的波动，是口语和阅读中一个重要但没有得到重视的方面。人类对语音韵律结构的敏感性各不相同，这似乎与阅读技能的个体差异有很强的联系。在神经和认知系统综合策略计划的支持下，这个项目将采取大胆的步骤，通过一系列创造性的方法和研究环境来研究韵律的生物学和功能。随着这类数据集的首次出现，该项目打算在整合来自大量人群样本的跨方法和水平(遗传学、神经成像和行为任务表现)的韵律的神经生物学基础方面取得关键进展。除了科学进步，拟议项目中概述的活动将使研究团队能够为改善STEM教育和教育者发展做出贡献，解决阅读障碍等神经发育障碍，增加公众对科学技术的参与，并加强跨学术网站的大数据合作伙伴关系。韵律的潜在生物学在神经和遗传水平上知之甚少，尽管它在人类交流技能中具有重要作用。需要多学科方法的创新组合，在大样本中收集新的数据，并利用现有的大规模资源，以产生对韵律生物学和功能的重要知识。这项建议的第一个目标将包括一系列研究，使用脑电、眼球跟踪和标准化行为任务来探索在语音感知和阅读的生态有效情景中注意韵律线索的时间动态过程，并考察韵律敏感性对阅读中个体差异的贡献。第二个目标将是一项关于韵律敏感性的全基因组关联研究，将通过在美国各地在线招募的个人以及田纳西州中部地区当地社区和教育机构的面对面个人进行不同样本的研究。尖端基因组学方法(PrediXcan和基因集浓缩分析)将被用来识别导致韵律个体差异的遗传标记和新的神经内表型(脑组织中的基因表达)。这一系列研究为未来计划中的研究奠定了必要的基础，这些研究试图理清韵律和语言功能的其他方面的共同和独立的基因结构，并可能揭示推动阅读和语言技能个体差异的生物机制的变革性知识。该合作研究项目利用了该团队在认知神经科学、心理语言学、沟通障碍和人类遗传学方面的不同背景。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
