PHONOLOGICAL SYSTEMS AFTER LONGTERM COCHLEAR IMPLANT US

该项目的目标是调查长期使用人工耳蜗术后，语前深度聋儿童的语音系统。先前的研究表明，人工耳蜗术可以有效地促进严重听力障碍儿童的言语感知和言语产生。然而，由于相对较新地引入人工耳蜗作为儿科患者的一种治疗选择，在使用设备的三年后还没有对言语产生进行评估。利用临床语言学的方法和技术，拟议的项目将提供有关十名使用人工耳蜗术更长时间(至少五年)的儿童的语音知识和潜在语言系统的详细信息。因此，拟议的项目将首次提供关于长期使用人工耳蜗的人实际发展的语音系统的详细信息，关于这些系统与目标系统之间的差异的信息，以及关于这些系统的发展和变化的方向的信息。这项研究的数据将提供有关使用一种在人类历史上独一无二的听觉输入(电刺激)来发展语言的方式的重要新知识。具体地说，它将提供关于这种类型的听觉输入如何促进类似于目标语音系统的语音系统的发展的新信息。

The goal of this project is to investigate the phonological systems of prelingually profoundly deafened children after long- term use of cochlear implants. Previous research has demonstrated that cochlear implants can be an effective device for promoting both speech perception and speech production in children with profound hearing impairment. However, because of the relatively recent introduction of cochlear implants as a treatment option for pediatric patients, speech production has not been assessed much beyond three years of device use. Using methods and techniques from clinical linguistics, the proposed project will provide detailed information regarding the phonological knowledge and underlying linguistic systems of ten children who have used cochlear implants for a much longer time, at least five years. The proposed project will therefore provide for the first time detailed information about the phonological systems that long-term users of cochlear implants actually develop, information about the differences between these systems and the target system, and information about directions of development and change in these systems. Data from this study will provide important new knowledge regarding the way in which language can develop using a type of auditory input (electrical stimulation) that is unique in the history of humankind. Specifically, it will provide new information about how this type of auditory input can facilitate the development of phonological systems similar to target phonological systems.
