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， 先天性聋儿的言语发育速度加快， 通信言语和语言发展理论预测， 植入应该为言语和语言提供改善的益处 发展，而且，言语和语言发展的增长应该是 在孩子接近青春期时受到约束。第一次纵向研究 将评估言语，语言和听觉感知的几项措施， 助听器使用的好处在婴儿期的指数。我们的目标是 这些措施可能最终有助于确定植入候选人。 另外两项纵向研究提出，将测试是否有 是对发育的限制，可以在有耳蜗的儿童中表现出来， 植入物.一项研究将跟踪植入12至36个月的儿童 老了24个月。在此期间，我们计划监测他们的讲话， 语言和听觉知觉的发展，以确定是否更早 植入影响生长速率和24个月刺激后的成就 程度.第二项纵向研究关注的是患有at 至少10年的植入经验。我们计划研究语言的增长， 语言从5到至少10年后刺激;我们还将检查 刺激后10年的成就，以确定 长期增长。我们还将研究长期成就 水平接近正常听力青少年和成人的水平。的 植入对言语产生和语言发展的好处也 导致预测在阅读中将存在后续增益， 这些孩子的学业成绩。早期阅读成绩 在二年级和以后的阅读和学业成绩在10年级将 在两个横向研究中进行检查。最后， 植入者言语和语言发育似乎超过了发现的 在许多有更多听觉的孩子身上，他们戴着助听器。一 横断面设计将比较学龄植入物使用者与 助听器使用者据预测，植入用户将有更好的 助听器使用者的听力水平比听力水平低的助听器使用者的听力水平高。
