我们在正常对话中处理的句子往往涉及我们熟悉的信息，而不是抽象的、不相关的信息。这允许使用知识存储来帮助促进理解过程。在许多句子理解研究中，刺激的设计使得世界知识的使用受到限制。本文研究了句子成分的语义相关性对句子加工的影响。采用三因素设计，考察加工阶段（句子vs.探针）、句法复杂性（宾语关系vs.主动连词）和句内名词的语义关联。我们发现在左侧额下回（LIFG）的两个亚区有不同的影响。ba44显示了句法复杂性的影响，而LIFG的下层部分（ba47）显示了相关性的影响以及复杂性和相关性在探针阶段的相互作用。此外，句子加工阶段和探查阶段在激活方面存在显著差异，句子阶段诱发的语义相关激活较强，而探查阶段诱发的工作记忆相关激活较强。
The sentences we process in normal conversation tend to refer to information that we are familiar with rather than abstract, unrelated information. This allows for the use of knowledge stores to help facilitate comprehension processes. In many sentence comprehension studies, the stimuli are designed such that the use of world knowledge is limited. Here we investigated how the semantic relatedness of sentence constituents influences sentence processing. A three factor design was employed in which processing phase (sentence vs. probe), syntactic complexity (object-relative vs. conjoined active) and the semantic relatedness of the nouns within the sentence was examined. We found a differential effect in two sub-regions of the left inferior frontal gyrus (LIFG). BA 44 revealed an effect of syntactic complexity while inferior portions of the LIFG (BA 47) revealed an effect of relatedness as well as an interaction between complexity and relatedness during the probe phase. In addition, significant differences in activation were observed when comparing the sentence processing and probe phases with the sentence phase eliciting stronger semantic related activation while the probe phase elicited stronger working memory related activation.
