语迹理论是生成语法框架下所提出的重要理论假设,但这种理论假设正确与否,句法表征中是否真正存在没有语音形式的语迹,必须得到与语言相关的脑神经机制的实验验证。本研究在生成语法理论背景下,利用高时间分辨率的事件相关电位技术,以汉语话题句为研究语料,考察了汉语语迹的神经机制问题。实验结果表明,在汉语话题句的加工过程中所诱发的持续负波、动词位置的负成分以及句末位置的P600成分,均反映了句首话题成分移位后会在原有位置留有语迹,二者之间存在句法依存关系。根据实验结果,我们认为,语迹在汉语话题句中有其神经机制,语迹理论假设的合理性能够得到大脑神经机制上的证明。同时研究也从神经机制的角度逆向证实了汉语话题句是经由移位生成的句法结构。
Trajectory theory is an important theoretical hypothesis proposed under the framework of generative grammar. However, whether this theory is correct or not and whether there is any trace of speech-free formal existence in syntactic representation must be verified by linguistic-related brain-nerve mechanisms. Under the background of generative grammar theory, this study uses the event-related potential technique with high temporal resolution to study the neural mechanism of Chinese language traces with Chinese topic sentences as the research corpus. The experimental results show that the persistent negative wave induced during the processing of Chinese topic sentences, the negative component of the verb position and the P600 component at the end of the sentence all reflect the traces of the original topic after the component topic shift , There is syntactic dependence between the two. According to the experimental results, we believe that the trace has its neural mechanism in Chinese topic sentences, and the rationality of the trace theory hypothesis can be proved by the neural mechanism of the brain. At the same time, the research also reversely confirmed from the perspective of neural mechanism that the Chinese topic sentence is a syntactic structure generated by the shift.
