我们介绍了两个实验，考察了母语和非母语人士对口语句子的句法和语义加工。在第一个实验中，使用功能磁共振成像(FMRI)确定了两种不同语言的母语使用者检测句法和语义违规所对应的神经底物。结果表明，不同母语受试者对刺激的潜在神经反应是非常相似的。在第二个实验中，我们研究了非母语使用者如何处理第一个实验中呈现的相同刺激。首先，研究结果显示，本族语和非本族语者对语义违规的反应比对句法违规的反应更相似。第二，观察到非母语者使用额颞语网络的特定部分与本族语者使用的不同。这些区域包括额下回(IFG)、颞上回(STG)和基底节的皮质下结构。(C)2005年Wiley-Liss，Inc.
We introduce two experiments that explored syntactic and semantic processing of spoken sentences by native and non-native speakers. In the first experiment, the neural substrates corresponding to detection of syntactic and semantic violations were determined in native speakers of two typologically different languages using functional magnetic resonance imaging (fMRI). The results show that the underlying neural response of participants to stimuli across different native languages is quite similar. In the second experiment, we investigated how non-native speakers of a language process the same stimuli presented in the first experiment. First, the results show a more similar pattern of increased activation between native and non-native speakers in response to semantic violations than to syntactic violations. Second, the non-native speakers were observed to employ specific portions of the frontotemporal language network differently from those employed by native speakers. These regions included the inferior frontal gyrus (IFG), superior temporal gyrus (STG), and subcortical structures of the basal ganglia. (c) 2005 Wiley-Liss, Inc.
