The involvement of neural motor and sensory systems in the processing of language has so far mainly been studied in native (L1) speakers. In an fMRI experiment, we investigated whether non-native (L2) semantic representations are rich enough to allow for activation in motor and somatosensory brain areas. German learners of Dutch and a control group of Dutch native speakers made lexical decisions about visually presented Dutch motor and non-motor verbs. Region-of-interest (ROI) and whole-brain analyses indicated that L2 speakers, like L1 speakers, showed significantly increased activation for simple motor compared to non-motor verbs in motor and somatosensory regions. This effect was not restricted to Dutch-German cognate verbs, but was also present for non-cognate verbs. These results indicate that L2 semantic representations are rich enough for motor-related activations to develop in motor and somatosensory areas.
到目前为止，神经运动和感觉系统在语言处理中的参与情况主要是在母语（L1）使用者中进行研究的。在一项功能磁共振成像（fMRI）实验中，我们调查了非母语（L2）语义表征是否丰富到足以在运动和体感脑区产生激活。荷兰语的德语学习者和一组以荷兰语为母语的对照组对视觉呈现的荷兰语运动动词和非运动动词进行词汇判断。感兴趣区域（ROI）和全脑分析表明，与母语使用者一样，第二语言使用者在运动和体感区域中，与非运动动词相比，简单运动动词的激活显著增加。这种效应不仅限于荷兰语 - 德语同源动词，非同源动词也存在这种效应。这些结果表明，第二语言语义表征足够丰富，足以在运动和体感区域产生与运动相关的激活。
