PROJECT SUMMARY Oral reading fluency predicts silent reading comprehension in developing readers, but the underlying neurocognitive mechanisms of this relationship are unknown. It is critical to understand these mechanisms, as the relationship between fluency and comprehension supports the inclusion of fluency in national literacy policy; fluency instruction to improve comprehension however, cannot be optimized if the mechanistic pathway linking these faculties is unclear. Moreover, understanding the mechanistic pathway between fluency and comprehension in typical reading development can provide neurocognitive targets for remediation in struggling readers, including children diagnosed with dyslexia. Oral reading prosody, a component of oral reading fluency, has recently been shown to carry a unique portion of the fluency to comprehension relationship, that is separable from the contributions of automatic decoding. We propose that meter, a component of prosody concerning the organization of stress, plays a key role in this process. Our overarching hypothesis is that maturation of oral reading prosody coincides with maturing fluency of “inner voice” auditory imagery (i.e., implicit prosody) during silent reading, leading to improved comprehension. We predict that developing readers with improved oral reading meter will have improved implicit representation of metric structure at the neural level (Aim 1), and improved application of implicit metric structure during silent reading (Aim 2), in a manner that improves silent reading comprehension (Aim 3). We will test our hypothesis by measuring oral reading meter, neural implicit metric representation, and realization of implicit metric structure in eye movements during silent reading in children between the ages of 6 and 10 years old, a developmental epoch within which oral prosody and silent reading undergo significant maturation. We will model how the adult-likeness of implicit metric representation and realization mediate the relationship between oral reading meter and standardized measures of silent reading comprehension, covarying for automatic decoding and phonological awareness. This work will provide clear insight into the mechanisms relating oral reading fluency to silent reading comprehension, which will inform national educational policy and provide mechanistic targets for remediation training in struggling readers. Moreover, this work will provide our team of undergraduate researchers training in using human electrophysiology and behavior to interrogate the neurocognitive underpinnings of complex behavioral development, providing footing for a competitive future in academia, clinical practice, or biomedical industry.

项目概要 口语阅读流畅度预示着发展中读者的默读理解能力，但潜在的 这种关系的神经认知机制尚不清楚，了解这些机制至关重要。 流利程度和理解力之间的关系支持将流利程度纳入国家扫盲政策； 然而，如果机械路径连接，则无法优化流利性教学以提高理解力 此外，对流畅性和流畅性之间的机制路径的理解还不清楚。 典型阅读发展中的理解可以为挣扎中的补救提供神经认知目标 读者，包括被诊断患有阅读障碍的儿童 口语阅读韵律，口语阅读流畅性的组成部分， 最近被证明具有流畅性与理解关系的独特部分，即可分离的 我们从自动解码的贡献中提出了韵律的一个组成部分。 压力的组织在这个过程中起着关键作用，我们的首要假设是口腔的成熟。 阅读韵律与“内心声音”听觉意象（即隐含韵律）的成熟流畅相一致。 默读可以提高理解能力，我们预测，培养读者的口语能力会得到提高。 读取仪表将在神经层面改进度量结构的隐式表示（目标 1），并且 改进默读期间隐式度量结构的应用（目标 2），以改进默读的方式 阅读理解（目标 3）。我们将通过测量口语阅读量、神经内隐式来检验我们的假设。 默读过程中眼动的度量表示和隐式度量结构的实现 6岁至10岁的儿童，是口语韵律和默音的发展时期 我们将模拟隐式度量表征如何与成人相似。 和实现调解口读计与默读标准化措施之间的关系 这项工作将提供清晰的理解，涵盖自动解码和语音意识。 深入了解口语阅读流畅性与默读理解之间的机制，这将有助于 国家教育政策，并为困难读者的补救培训提供机械目标。 此外，这项工作将为我们的本科研究人员团队提供使用人类的培训 电生理学和行为来探究复杂行为的神经认知基础 发展，为学术界、临床实践或生物医学行业的竞争性未来奠定基础。
