DESCRIPTION (provided by applicant): The proposed study examines the development of the neural substrate for speech perception between the ages of 4 and 15 years. Although speech perception develops very rapidly during the first year of life, the sensitive period for native-like speech perception closes much later. The first aim, of this proposal is to study second-language speech perception in adults varying in their age of acquisition (AOA) in order to specify the sensitive period for speech perception. The second aim is to understand the changes that result in this decline in plasticity by studying the discrimination of native-language speech sounds, speech in noise, and foreign-language speech sound in children at various points of this sensitive period. The use of fMRI techniques, along with dishabituation paradigms will provide information about the development of the neural substrate for speech perception. Furthermore, these "task-free" paradigms for studying perception also have methodological advantages over other behavioral paradigms used to study speech perception. In particular, the same tasks can be used with child and adult participants, allowing for direct comparison of data from the two specific aims of this proposal.

描述（由申请人提供）：拟议的研究检查了神经基板在4至15岁之间的语音感知的发展。尽管在生命的第一年，语音感知发展迅速，但类似母语的言语感知的敏感时期在很久以后就会结束。该提案的第一个目的是研究成年人在收购年龄（AOA）中不同的第二语言语音感知，以指定语音感知的敏感时期。第二个目的是通过研究本敏感时期各个点的儿童中的本地语言语音，噪声中的语音和外语语音的歧视来了解导致可塑性下降的变化。 fMRI技术的使用以及不清楚的范例将提供有关神经基板的发展以进行语音感知的信息。此外，这些用于研究感知的“无任务”范例也比用于研究语音感知的其他行为范式具有方法上的优势。特别是，可以与儿童和成人参与者一起使用相同的任务，从而可以直接比较该提案的两个特定目的的数据。
