 DESCRIPTION (provided by applicant): Behavioral assessment is the gold standard for characterizing hearing in infants and children, in both clinical and laboratory settings. Behaviora data play a critical role in the diagnosis and treatment of hearing loss, and they represent our most comprehensive source of information about the time-course of typical auditory development. Despite their practical and theoretical importance, the interpretation of behavioral data is complicated by the contribution of multiple factors, including sensorineural encoding of sound, central auditory processing, and cognitive factors specific to behavioral testing. Disentangling these factors is essential to accurately describing human auditory development, and to the diagnosis of hearing loss and accurate fitting of auditory prostheses during infancy and childhood. The long-term goal of this research is to identify the factors responsible for immature auditory behavior in infants and children, and to develop techniques for differentiating the contributions of these factors in individual listeners. This is accomplished with three specifi aims. The first aim is to test the hypothesis that self-generated noise elevates detection thresholds in young listeners, particularly at low frequencies. The second aim is to evaluate central auditory processing and general cognitive factors limiting performance of young listeners, including memory for pitch and loudness, the ability to listen selectively in frequency r time, and the ability to capitalize on the context present in a closed-set speech recognition task. The third aim is to evaluate novel procedures for improving behavioral assessment of hearing in infants, toddlers, and `hard-to-test' children with hearing loss. The proposed work is of theoretical and clinical significance, in that it examines how the various factors contributing to auditory behavior limit performance across age and within individuals. The results obtained are expected to advance assessment methodologies in clinical and basic science settings.

 描述（由应用提供）：行为评估是临床和实验室环境中婴儿和儿童听力的表征的黄金标准。行为数据在听力损失的诊断和治疗中起着至关重要的作用，它们代表了我们有关典型听觉开发时间的最全面信息来源。尽管它们的实用和理论上的重要性，但行为数据的解释是通过多种因素的贡献（包括声音的感觉编码，中央听觉处理以及特定于行为测试的认知因素）来汇总的。解开这些因素对于准确描述人类听觉发展以及在婴儿期和童年期间的听觉假体的准确配合至关​​重要。这项研究的长期目标是确定负责婴儿和儿童未成熟听觉行为的因素，并开发用于区分这些因素在单个听众中的贡献的技术。这是通过三个特定目标完成的。第一个目的是检验以下假设：自我生成的噪声会提高年轻听众的检测阈值，尤其是在低频下。第二个目的是评估中央听觉处理和一般认知因素限制年轻听众的表现，包括音高和响度的记忆力，在频率r时间中有选择性地聆听的能力以及在封闭式语音识别任务中利用上下文的能力。 第三个目的是评估新的程序，以改善婴儿，幼儿和“难以测试”听力损失的儿童的听力评估。拟议的工作具有理论和临床意义，因为它研究了各种因素如何促进听觉行为限制整个年龄和个体内部的表现。预期获得的结果将推进临床和基础科学环境中的评估方法。
