Abstract

Sentence comprehension is a complex process. Besides identifying the meaning of each word and processing the syntactic structure of a sentence, it requires the computation of thematic information, that is, information about who did what to whom. The present fMRI study investigated the neural basis for thematic reanalysis (reanalysis of the thematic roles initially assigned to noun phrases in a sentence) and its interplay with syntactic reanalysis (reanalysis of the underlying syntactic structure originally constructed for a sentence). Thematic reanalysis recruited a network consisting of Broca's area, that is, the left pars triangularis (LPT), and the left posterior superior temporal gyrus, whereas only LPT showed greater sensitivity to syntactic reanalysis. These data provide direct evidence for a functional neuroanatomical basis for two linguistically motivated reanalysis processes during sentence comprehension.

摘要

句子理解是一个复杂的过程。除了识别每个单词的含义和处理句子的句法结构外,它还需要计算主题信息,即关于谁对谁做了什么的信息。本 fMRI 研究调查了主题再分析(重新分析句子中最初分配给名词短语的主题角色)及其与句法再分析(重新分析最初为句子构建的基础句法结构)相互作用的神经基础。主题再分析涉及包括布罗卡区(即左三角部)和左后上颞叶在内的网络,而只有 LPT 对句法再分析表现出更高的敏感性。这些数据为句子理解过程中的两种语言驱动的再分析过程提供了直接的功能神经解剖学基础。
