婴儿言语感知的知觉重组从 6 个月开始就已被发现，辅音和元音更早。最近，在 6 至 9 个月大的婴儿的词汇声调中也发现了类似的重组。鉴于元音和声调之间存在密切关系，本研究调查声调知觉重组是否早于 6 个月开始。使用刺激交替偏好程序，对非声调语言的英语和法语婴儿进行了泰语低声与升声词汇声调对比的测试。四个月和六个月大的婴儿能够辨别词汇声调，并且这些年龄段的辨别能力没有下降。然而，9个月大的孩子无法辨别词汇声调。随着年龄的增长，规范声调辨别力下降的这种特殊模式表明，声调知觉重组与元音感知中观察到的发育前下降并不平行。该研究结果与之前关于英语婴儿声调感知的跨语言发育研究结果一致[Mattock, K., & Burnham, D. (2006)。中文和英文婴儿的声调感知：知觉重组的证据。婴儿期，10(3)]，并通过对学习节奏不同的非声调语言（英语和法语）的非声调语言婴儿表现出类似的知觉重组来扩展它们。皇冠版权所有 (C) 2007 由 Elsevier B.V 出版。保留所有权利。
Perceptual reorganisation of infants' speech perception has been found from 6 months for consonants and earlier for vowels. Recently, similar reorganisation has been found for lexical tone between 6 and 9 months of age. Given that there is a close relationship between vowels and tones, this study investigates whether the perceptual reorganisation for tone begins earlier than 6 months. Non-tone language English and French infants were tested with the Thai low vs. rising lexical tone contrast, using the stimulus alternating preference procedure. Four- and 6-month-old infants discriminated the lexical tones, and there was no decline in discrimination performance across these ages. However, 9-month-olds failed to discriminate the lexical tones. This particular pattern of decline in normative tone discrimination over age indicates that perceptual reorganisation for tone does not parallel the developmentally prior decline observed in vowel perception. The findings converge with previous developmental cross-language findings on tone perception in English-language infants [Mattock, K., & Burnham, D. (2006). Chinese and English infants' tone perception: Evidence for perceptual reorganization. Infancy, 10(3)], and extend them by showing similar perceptual reorganisation for non-tone language infants learning rhythmically different non-tone languages (English and French).
