AUDITORY PROCESSING IN HEARING IMPAIRED CHILDREN

描述：许多患有感觉神经性听力障碍的儿童 有足够的残余听力使用助听器和听觉/口头语言， 他们的主要沟通方式。 然而，成功的程度， 这些孩子对语言的理解能力差异很大，即使是那些 听力损失的程度和结构相同。 此问题可能是 如果我们能更好地了解 儿童听力障碍对言语知觉的影响 因此，从长远来看， 我们研究项目的目的是了解儿童听力 损害影响过程和表征的发展 准确的言语感知。 这项研究是合乎逻辑的 后续我们的研究Stroop（语义）干扰，并扩展这些 研究来解决一些语音问题。 的逻辑 关于心理的重要信息 言语知觉的表征和过程可能会被揭示出来， 通过研究语义或语音相关的听觉 探索图片命名（图片单词任务）。 试点数据显示， 有听力障碍的儿童表现出不同程度和时间进程的 语义和语音加工的相互作用。 我们提出了一个模型的 我们的任务的性能，并假设一些可能的修改， 这个模型可以解释听力正常的孩子 损伤 在试点数据具有代表性的情况下， 对图片文字测试的研究应该能对是否 语言处理的发展被延迟或发生质的变化， 儿童听力障碍的存在。 这些数据应提供 在理解语音本质方面具有临床价值的信息 听觉障碍儿童的感知，从而帮助我们更好地发展 促进正常沟通能力的计划。 数据应 提供理论上有价值的信息， 听觉经验的差异对言语发展的影响 处理.

DESCRIPTION: Many children with sensorineural hearing impairment have sufficient residual hearing to use hearing aids and aural/oral language as their primary mode of communication. Yet the degree of success in understanding speech varies widely in these children, even in those with the same degree and configuration of hearing loss. This problem might be significantly reduced if we had a better understanding of the effects of childhood hearing impairment on speech perception. Thus the long term objective of our program of research is to understand how childhood hearing impairment affects the development of the processes and representations underlying accurate speech perception. The proposed research is a logical follow-up to our studies of Stroop (semantic) interference and extends these studies to address some phonological issues as well. The logic of the proposed studies is that important information about the mental representations and processes involved in speech perception may be revealed by studying the effects of semantically- or phonologically-related auditory probes on picture naming (picture word task). Pilot data suggest that children with hearing impairment show a different degree and time course of semantic and phonological processing interactions. We present a model of performance on our task and hypothesize about some possible modifications of the model that might account for results in the children with hearing impairment. To the extent that the pilot data are representative, results on the picture word test should yield important insights into whether the development of speech processing is delayed or qualitatively changed in the presence of childhood hearing impairment. Such data should provide information of clinical value in terms of understanding the nature of speech perception by hearing impaired children, thus helping us to develop better programs for promoting normal communication abilities. The data should provide information of theoretical value in terms of understanding the effects of differences in auditory experience on the development of speech processing.
