This proposal requests continued support of a program of research on children with profound hearing impairments. The long-term goal of this project is to obtain a better understanding of the benefits derived from multichannel cochlear implants (CIs) and from conventional amplification (HA). In particular, we are interested in the effects of cochlear implants on the development of speech perception, spoken word recognition, and language skills, as well as the influence of audition on selective attention. The proposed research involves extensions of our earlier comparisons of sensory aids in deaf children. First, we propose to examine the effects of age at implantation on speech and language development. Second, we plan to compare the performance of children with CIs to children with HAs, to assess the benefits obtained from CIs by children with different degrees of hearing loss. Third, we will compare CI processor strategies, specifically waveform representation vs feature extraction. Fourth, we will continue our earlier research on the effects of audition on visual attention. Finally, we propose to study exceptional users of CIs to learn more about the sensory and perceptual mechanisms that underlie their superior performance on traditional speech perception tests. Taken together the findings from this project will provide new information concerning audiological criteria for CI candidacy. The results will also provide information concerning the efficacy of new CI processor strategies in facilitating perceptual development, specifically, speech perception, language development, and selective attention, in children with profound hearing impairments.

该提案要求继续支持一项研究计划 有严重听力障碍的儿童。这个长期目标 项目是为了更好地了解从 多通道人耳蜗植入物（CI）和传统放大 （哈）。特别是，我们对人工耳蜗的影响感兴趣 植入语音感知的发展，口语 识别和语言技能以及试镜的影响 在选择性注意力上。拟议的研究涉及我们的扩展 早期比较聋哑儿童的感觉辅助工具。首先，我们建议 检查植入时的年龄对语音和语言的影响 发展。第二，我们计划将儿童的表现与 为患有HAS的儿童的顺式评估从CIS获得的收益 听力损失程度不同的儿童。第三，我们将比较 CI处理器策略，特别是波形表示与功能 萃取。第四，我们将继续对影响的早期研究 视觉关注的试镜。最后，我们建议研究 独联体的杰出用户，以了解有关感官和感知的更多信息 在传统上表现出色的机制 语音感知测试。总结了这个项目的发现 将提供有关CI听力学标准的新信息 候选人。结果还将提供有关 新的CI处理器策略在促进感知方面的功效 发展，特别是语音感知，语言发展和 有选择性的关注，对听力障碍的儿童。
