Project Summary/Abstract Hearing and listening are critical to how adolescents communicate, learn new information, and engage with technology and culture; however, performance on auditory perceptual tasks takes a long time to become mature. Because few studies of auditory perception have centered on typically-developing adolescents, little is known about the mechanisms underlying this immaturity. The lack of knowledge of the processes underlying the prolonged maturation of hearing and listening abilities in typical listeners can lead to difficulties in the diagnosis of auditory processing disorders and other communication disorders, thus affecting public health. The long- term goal of this project is to elucidate the mechanisms underlying the development of auditory perception during adolescence. The present objective is to evaluate the extent to which auditory stimulus encoding and various cognitive processes contribute to immature auditory perception during adolescence. The central hypothesis is that immature performance on auditory and speech perception tasks during adolescence can be attributed to both maturational changes in temporal encoding and to developmental improvements in the specific cognitive processes required by each task. This hypothesis will be tested by pursuing two specific aims: (1) Evaluate the contribution of auditory temporal processing and cognitive functions to immature naïve performance on basic auditory tasks during adolescence. (2) Evaluate the contribution of auditory temporal processing and cognitive functions to naïve performance on speech perception tasks during adolescence. These aims will be addressed using a combination of perceptual testing, pupillometry and blink-rate to index cognitive processes engaged during active listening, auditory evoked potentials to index temporal and spectral encoding during unattended stimulus presentations, and standardized neuropsychological and language tests to evaluate processes with known maturational courses. This project will yield experimental protocols that will be applicable for the development of diagnostic tests regarding auditory processing in adolescents and young adults. It also could inform future therapies that aim to support or improve the processes underlying auditory perception in adolescents and young adults with communication disorders.

项目概要/摘要 听力和倾听对于青少年如何沟通、学习新信息、 并参与技术和文化；然而，听觉感知任务的表现 因为很少有研究集中于听觉感知。 对于正常发育的青少年，人们对其背后的机制知之甚少 缺乏对长期成熟过程的了解。 典型听众的听力和聆听能力可能会导致听觉诊断的困难 处理障碍和其他沟通障碍，从而影响公共健康。 该项目的长期目标是阐明听觉发展的潜在机制 目前的目标是评估青春期的听觉程度。 刺激编码和各种认知过程导致不成熟的听觉感知 青春期的中心假设是听觉和言语表现不成熟。 青春期的感知任务可归因于时间的成熟变化 编码和发展改善所需的特定认知过程 每个任务都将通过追求两个具体目标来检验：（1）评估 听觉时间处理和认知功能对不成熟幼稚的贡献 (2)评估听觉的贡献 时间处理和认知功能对语音感知任务的幼稚表现 在青春期，这些目标将通过结合感知测试来实现， 瞳孔测量和眨眼频率可用于索引主动聆听、听觉过程中的认知过程 在无人照管刺激期间诱发电位来索引时间和频谱编码 演示以及标准化神经心理学和语言测试来评估过程 与已知的成熟课程一起，该项目将产生实验方案。 适用于开发有关青少年听觉处理的诊断测试 它还可以为未来旨在支持或改善的疗法提供信息。 青少年和年轻人沟通的听觉感知的基本过程 失调。
