This proposal requests continued support for a program of basic and clinical 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 conventional amplification (HA). In particular, we are interested in the effects of cochlear implants on the development of speech perception, spoken word recognition, and receptive language skills. The proposed research is organized into three projects. First, we propose to examine the effects of age at implantation on speech and language development in a group of children who are all implanted prior to age five years. 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 propose to investigate individual differences and variation in the effectiveness of CIs using new cognitive measures of working memory and learning. Taken together the findings from this project will provide new information concerning audiological criteria for CI candidacy and the underlying sensor, perceptual and cognitive basis for individual differences in spoken word recognition and receptive language outcome measures. Understanding the nature of the wide individual differences to the effectiveness of CIs in young children is critical for predicting individual benefits prior to surgery and selecting appropriate intervention strategies following implantation.

该提案要求继续支持对有严重听力障碍儿童的基础和临床研究计划。 该项目的长期目标是更好地了解来自多通道人耳蜗（CIS）和常规放大（HA）的收益。 特别是，我们对人工耳蜗对语音感知，口语识别和接受语言技能的发展感兴趣。 拟议的研究分为三个项目。 首先，我们建议研究植入时代对一群五岁之前植入的儿童言语和语言发展的影响。 其次，我们计划将带有CIS儿童的表现与患有HAT的儿童的表现进行比较，以评估听力损失程度不同的儿童从CI中获得的收益。第三，我们建议使用新的工作记忆和学习的新认知度量来研究CI的个体差异和差异。 综上所述，该项目的发现将提供有关CI候选人资格和基础传感器，感知和认知基础的新信息，涉及口语识别和接受语言结果指标的个体差异。 了解CIS在幼儿中的有效性的广泛个体差异对于预测手术前的个人收益和选择适当的干预策略至关重要。
