对于成人和儿童来说，声学语境在言语感知中起着重要的作用。对于成年人来说，语音和非语音的声学环境的影响感知随后的语音项目，一致的论点，上下文的影响是由于域一般的听觉过程。然而，以前的研究检查的影响，儿童的言语知觉的语境都集中在言语语境，非言语语境还没有探索以前。为了更好地了解儿童使用语境的言语知觉的发展进程和发展的机制，我们创建了一个新的实验范式测试5岁儿童的言语知觉在几个声学背景。结果表明，非言语语境影响儿童的言语感知，与上下文效应产生于一般听觉系统特性而不是言语特定机制的说法一致。这支持了语言发展的理论解释，即领域一般过程在整个生命周期中发挥作用。(C)2013 Elsevier Inc.

For both adults and children, acoustic context plays an important role in speech perception. For adults, both speech and nonspeech acoustic contexts influence perception of subsequent speech items, consistent with the argument that effects of context are due to domain-general auditory processes. However, prior research examining the effects of context on children's speech perception have focused on speech contexts; nonspeech contexts have not been explored previously. To better understand the developmental progression of children's use of contexts in speech perception and the mechanisms underlying that development, we created a novel experimental paradigm testing 5-year-old children's speech perception in several acoustic contexts. The results demonstrated that nonspeech context influences children's speech perception, consistent with claims that context effects arise from general auditory system properties rather than speech-specific mechanisms. This supports theoretical accounts of language development suggesting that domain-general processes play a role across the lifespan. (C) 2013 Elsevier Inc. All rights reserved.
