本文提出了一个描述理解过程中句法过程的时间结构和神经拓扑结构的模型。它假设了语言理解的三个不同阶段，其中两个主要是句法性质的。在第一阶段，解析器根据词类别信息分配初始句法结构。这些早期的结构过程被认为是subserved由左半球的前部，事件相关的脑电位显示，该地区被最大限度地激活时，短语结构的违规行为进行处理，并在该地区的局限性病变导致在线结构分配的损害。在第二阶段，词汇语义和动词论元结构信息被处理。这一阶段是神经生理学表现在事件相关的脑电位的负成分在400 ms左右的刺激开始时，分布在左，右颞顶区时，词汇语义信息的处理和左前区时，动词论元结构信息的处理。在第三阶段，分析器试图将初始句法结构映射到可用的词汇语义和动词论元结构信息上。如果两种类型的信息之间不匹配，则可能需要重新分析。这些结构再分析的过程与事件相关脑电位中centroparietally分布的晚期阳性成分相关。事件相关脑电位的不同时间和地形图模式。以及失语症患者的理解行为的某些方面被用来支持这一观点，即这些不同的加工阶段是不同的，特别是左前皮层，负责句法结构的在线分配。(C)出版社：Academic Press
This paper presents a model describing the temporal and neurotopological structure of syntactic processes during comprehension. It postulates three distinct phases of language comprehension, two of which are primarily syntactic in nature. During the first phase the parser assigns the initial syntactic structure on the basis of word category information. These early structural processes are assumed to be subserved by the anterior parts of the left hemisphere, as event-related brain potentials show this area to be maximally activated when phrase structure violations are processed and as circumscribed lesions in this area lead to an impairment of the on-line structural assignment. During the second phase lexical-semantic and verb-argument structure information is processed. This phase is neurophysiologically manifest in a negative component in the event-related brain potential around 400 ms after stimulus onset which is distributed over the left and right temporo-parietal areas when lexical-semantic information is processed and over left anterior areas when verb-argument structure information is processed. During the third phase the parser tries to map the initial syntactic structure onto the available lexical-semantic and verb-argument structure information. In case of an unsuccessful match between the two types of information reanalyses may become necessary. These processes of structural reanalysis are correlated with a centroparietally distributed late positive component in the event-related brain potential. The different temporal and topographical patterns of the event-related brain potential. as well as some aspects of aphasics' comprehension behavior are taken to support the view that these different processing phases are distinct and that the left anterior cortex, in particular, is responsible for the on-line assignment of syntactic structure.
