泰语是一种在元音长度上表现出音素对立的语言，它使我们能够比较语言和非语言背景中的时间模式。功能磁共振成像数据收集泰国和英语科目的快速反应，选择性注意范式，因为他们进行相同/不同的判断元音持续时间和辅音（泰国语讲话）和嗡嗡声持续时间（nonspeech）。激活主要发生在左下前额叶皮层在两个语音任务的泰国组，但只有在辅音任务的英语组。泰语组在两种言语任务中都表现出左侧中上级颞回的激活;英语组在双侧后上级颞回。在嗡嗡声持续时间任务中，两组的前额叶皮层都出现了激活峰值。这些跨语言的数据表明，编码的复杂的听觉信号的影响，他们在特定的语言中的功能作用。(C)2002 Elsevier Science（美国）。All rights reserved.
Thai, a language which exhibits a phonemic opposition in vowel length, allows us to compare temporal patterns in linguistic and nonlinguistic contexts. Functional MRI data were collected from Thai and English subjects in a speeded-response, selective attention paradigm as they performed same/different judgments of vowel duration and consonants (Thai speech) and hum duration (nonspeech). Activation occurred predominantly in left inferior prefrontal cortex in both speech tasks for the Thai group, but only in the consonant task for the English group. The Thai group exhibited activation in the left mid superior temporal gyrus in both speech tasks; the English group in the posterior superior temporal gyrus bilaterally. In the hum duration task, peak activation was observed bilaterally in prefrontal cortex for both groups. These crosslinguistic data demonstrate that encoding of complex auditory signals is influenced by their functional role in a particular language. (C) 2002 Elsevier Science (USA). All rights reserved.
