AUDITORY PROCESSING IN HEARING IMPAIRED CHILDREN

描述：许多感音神经性听力障碍的儿童 足够的剩余听力以使用助听器和听觉/口头语言作为 他们的主要沟通方式。然而，在中国的成功程度 这些儿童对言语的理解差异很大，即使是在那些患有 相同程度和形态的听力损失。这个问题可能是 如果我们更好地了解 儿童听力障碍对言语感知的影响。因此，从长远来看 我们研究项目的目标是了解儿童听力 损伤会影响加工和表征的发展 潜在的准确的语音感知。拟议的研究是合乎逻辑的 我们对Stroop(语义)干扰研究的后续行动，并扩展了这些 研究也解决了一些语音问题。这其中的逻辑 提出的研究是关于心理健康的重要信息 涉及言语知觉的表征和过程可以被揭示 通过研究与语义或语音相关的听觉的影响 关于图片命名(图片单词任务)的探讨。试点数据表明， 听力障碍儿童表现出不同程度和时间进程的听力障碍 语义和语音加工的交互作用。我们提出了一个模型 我们任务的执行情况和关于可能的一些修改的假设 可能解释听力障碍儿童结果的模型 减损。在试点数据具有代表性的情况下，结果 关于图片单词测试应该会产生重要的洞察力 语音处理的发展被推迟或质的改变在 儿童时期存在听力障碍。这样的数据应该提供 在理解言语本质方面具有临床价值的信息 听障儿童的感知能力，从而帮助我们更好地发展 促进正常沟通能力的计划。数据应该是 提供有理论价值的信息，帮助您了解 听觉体验差异对言语发展的影响 正在处理。

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.
