Abstract

In this study, the neural mechanisms of dynamic syntactic and semantic processing in Chinese garden-path sentence comprehension were investigated using electrophysiological and behavioral measures. Two groups of garden-path sentences were designed, with the ambiguity of multiple word categories in Group 1 and classifier-noun agreements in Group 2. Besides the ambiguous condition, there were also control and semantic violation conditions. Participants made plausibility judgment of each sentence. The ERPs elicited by the last three critical word regions in each sentence were examined continuously to uncover the time course of the revision process clearly. Relative to the control sentence, the ambiguous sentences of both groups elicited the smallest N400 before and on the disambiguating region, but the largest P600 at the disambiguation position, indicating that the sentences were misparsed and/or misinterpreted initially, and revised efficiently when the input cannot be integrated into the syntactic structure constructed. No significant N400 difference was observed between the ambiguous and the control condition on the disambiguating regions, indicating that semantic processing proceeded even no appropriate syntactic structures were built for the incomplete sentences. Therefore, without morphosyntactic constraints in Chinese, semantic processing is generally prior to the syntactic one, which will be revised only when semantic integration fails.
汉语园路句理解中动态句法和语义处理的神经机制:ERP研究
本研究采用电生理和行为测量方法研究了汉语花园路径句理解中动态句法和语义加工的神经机制。研究设计了两组园路句子,第一组为多词类歧义句,第二组为分类词-名词一致句。受试者对每个句子进行可信度判断。为了清楚地揭示修改过程的时间进程,我们对每个句子中最后三个关键词语区域所引起的ERPs进行了连续检测。相对于对照组句子,两组模棱两可的句子在消歧义区域前和消歧义区域上引起的N400最小,但在消歧义位置上引起的P600最大,这表明句子最初被误读和/或误解,当输入无法整合到构建的句法结构中时,句子被有效地修正。在消歧义区域,模棱两可和对照条件之间没有观察到明显的 N400 差异,这表明即使没有为不完整的句子构建适当的句法结构,语义处理也在进行。因此,在没有形态句法限制的情况下,汉语的语义加工一般先于句法加工,只有当语义整合失败时,句法加工才会被修正。

期刊介绍: The Journal of Neurolinguistics is an international forum for the integration of the neurosciences and language sciences. JNL provides for rapid publication of novel, peer-reviewed research into the interaction between language, communication and brain processes. The focus is on rigorous studies of an empirical or theoretical nature and which make an original contribution to our knowledge about the involvement of the nervous system in communication and its breakdowns. Contributions from neurology, communication disorders, linguistics, neuropsychology and cognitive science in general are welcome. Published articles will typically address issues relating some aspect of language or speech function to its neurological substrates with clear theoretical import. Interdisciplinary work on any aspect of the biological foundations of language and its disorders resulting from brain damage is encouraged. Studies of normal subjects, with clear reference to brain functions, are appropriate. Group-studies on well defined samples and case studies with well documented lesion or nervous system dysfunction are acceptable. The journal is open to empirical reports and review articles. Special issues on aspects of the relation between language and the structure and function of the nervous system are also welcome.
