DESCRIPTION (provided by applicant): Research has shown that implantation of congenitally deaf children accelerates their development of speech-based communication. Theories of speech and language development predict that earlier implantation should provide improved benefits for speech and language development, and also, that growth in speech and language development should be constrained as the child approaches adolescence. The first longitudinal study will evaluate several measures of speech, language, and auditory perception as indices of benefit from hearing aid use during infancy. It is our goal that these measures may ultimately help determine implant candidacy. Two additional longitudinal studies are proposed that will test whether there are constraints on development that can be shown among children with cochlear implants. One study will follow children implanted between 12- and 36- months old for 24 months. During this time period we plan to monitor their speech, language, and auditory perceptual development in order to determine if earlier implantation affects growth rates and 24-month, post-stimulation, achievement levels. The second longitudinal study concerns children and adolescents with at least 10 years of implant experience. We plan to examine growth in speech and language from 5 to at least 10 years post-stimulation; we will also examine achievement at 10 years post-stimulation to determine if there are limits to long-term growth. We will also examine the extent to which long-term achievement levels approach levels found in normal-hearing adolescents and adults. The benefits of implantation on speech production and language development also result in a prediction that there will be subsequent gains in reading and general scholastic achievement among these children. Early reading achievement in second grade and later reading and scholastic achievement in 10th grade will be examined in two cross-sectional studies. Finally, achievement levels of speech and language development among implant users appears to exceed that found in many children with more acoustic hearing who wear hearing aids. A cross-sectional design will compare school-age implant users with age-mates who are hearing aid users. It is predicted that implant users will have better speech and language than hearing aid users with low audibility levels.

描述（由申请人提供）：研究表明植入 先天性聋哑儿童加速了他们基于语音的发展 沟通。言语和语言发展的理论预测 植入应为语音和语言提供改进的好处 发展，言语和语言发展的增长应该是 随着孩子接近青春期的约束。第一个纵向研究 将评估几种语音，语言和听觉看法的措施 婴儿期助听器使用受益的指标。我们的目标是 这些措施最终可能有助于确定植入物资格。 提出了另外两项纵向研究，以测试是否存在 是对发育的限制，可以在人工耳蜗的儿童中显示 植入物。一项研究将跟随12个月至36个月之间植入的儿童 老了24个月。在此期间，我们计划监视他们的演讲， 语言和听觉感知发展，以确定是否较早 植入会影响增长率和24个月的刺激后，成就 水平。第二项纵向研究涉及儿童和青少年AT 至少10年的植入经验。我们计划检查语音的增长和 刺激后5至少10年的语言；我们还将检查 刺激后10年的成就，以确定是否有限制 长期增长。我们还将研究长期成就的程度 在正常听力的青少年和成人中发现的水平接近水平。这 植入对语音生产和语言发展的好处 结果预测，阅读和 这些孩子中的一般学业成就。早期阅读成就 在二年级及以后的阅读和学业成就中，将 在两项横断面研究中进行检查。最后，成就水平 植入物用户之间的语音和语言发展似乎超过了发现的 在许多戴助听器的声音听力更多的孩子中。一个 横截面设计将比较学院时代的植入物用户与年龄伴侣 是助听器用户。据预测，植入物用户会更好 语音和语言比听觉性较低的助听器用户。
