摘要
选取一例汉语典型句法失语患者,将图片理解产出汉语肯定句和否定句作为实验任务,利用功能性磁共振成像扫描技术对患者的肯定句和否定句理解和产出加工过程进行研究。同时将同样任务让一组健康被试完成,并进行结果比照。研究结果表明失语患者与健康对照组均表现出否定句加工难于肯定句,证实了汉语否定效应的加工机制。磁共振成像研究结果还表明失语症患者脑损伤对侧半球句法加工脑区的显著激活体现了汉语句法损伤康复过程中的代偿机制。语迹删除假说、句法树削减假说和中心语干扰动词移位假说等理论与汉语否定效应句法加工复杂性的神经机制密切相关。
This paper uses fMRI(functional magnetic resonance imaging)experiment to compare the comprehension and production processing of affirmative and negative sentences of a typical Chinese syntactic aphasia patient with a group of healthy subjects.The results show that the negative sentence processing is more difficult than the affirmative sentence processing to reflect the cognitive processing mechanism of Chinese negative effect.The significant activation of contralateral syntactic processing brain regions in aphasia patient revealed by imaging indicates the compensatory mechanism in the rehabilitation of Chinese syntactic injury.Trace deleting hypothesis,pruning the syntactic tree hypothesis and central word interfering verb movement hypothesis are the possible theoretical explanations to the neural mechanism of the syntactic complexity processing of Chinese negative effect.
