导致听力障碍儿童言语和语言效果差的一个主要因素 损失可能与解决刺激的时间特征的能力降低有关。听觉颞叶 分辨率指的是随着时间推移感知声音刺激变化的能力。这样做的长期目标是 研究方案是了解影响时间分辨率发展的因素 在听力受损的儿童中可以被操纵用于治疗目的。朝着这个目标前进。AIM 1将测试 一种假设，即听力暴露越多的儿童在颞叶发育方面表现出的延迟越少 决议。将为不同的时间分辨率测量获得阈值。这些门槛将 在两组儿童(听力损失，听力正常)和不同年龄的儿童之间进行一系列比较 横断面实验。目标1下的工作将提供对时间分辨率的更好理解 在听力损失的儿童中，以及儿童的听觉经验支持他们的时间的程度 决议。目标2将测试助听器增益和压缩速度可以被操纵的假设 提高听力损失儿童的时间分辨率。听力损失会导致暂时性听力下降 由于听力丧失和耳蜗的正常压缩功能而导致的分辨率降低。我们缺乏信息 关于我们可以通过以下方式提高听力损失儿童的时间分辨率的程度 操纵放大提供的增益和压缩速度。这一贡献预计将是 意义重大，因为这是有望导致发展的一系列研究的第一步 康复策略，例如，将允许有针对性的干预，以降低风险 与促成次优时间分辨率的因素相关(目标1)，并允许 优化时间分辨率的助听器压缩速度规范(目标2) 听力损失。

A major factor contributing to the poor speech and language outcomes of children with hearing loss may be related to a reduced ability to resolve temporal features of the stimulus. Auditory temporal resolution refers to the ability to perceive changes in acoustic stimuli overtime. The long-term goal of this program of research is to understand how the factors that influence the development of temporal resolution in children with hearing loss can be manipulated for therapeutic purposes. Towards this goal. Aim 1 will test the hypothesis that children with greater auditory exposure show less delay in the development of temporal resolution. Thresholds will be obtained for different measures of temporal resolution. These thresholds will be compared between two groups of children (hearing loss, normal hearing) and across age in a series of cross-sectional experiments. The work under Aim 1 will provide a better understanding of temporal resolution in children with hearing loss and the degree to which a child's auditory experience supports their temporal resolution. Aim 2 will test the hypothesis that hearing-aid gain and compression speed can be manipulated to improve temporal resolution for children with hearing loss. Hearing loss can result in reduced temporal resolution due to loss of audibility and the normal compressive function of the cochlea. We lack information regarding the extent to which we can improve temporal resolution for children with hearing loss by manipulating the gain and compression speed provided by amplification. This contribution is expected to be significant because it is the first step in a continuum of research that is expected to lead to the development of habilitative strategies that will, for example, allow for targeted interventions that mitigate the risks associated with factors that contribute to suboptimal temporal resolution (Aim 1) and allow for the specification of hearing-aid compression speed that optimize temporal resolution (Aim 2) for children with hearing loss.
