本文从脑生理学的角度探讨了时间的语言表达，特别是时间副词和动词时态词素，是如何被用来建立时间参照的。首先，本文对时态副词和时间副词进行了形式语义分析。有人认为，计算时间参考相当于解决一个约束满足问题。接下来，一个事件相关电位（ERP）研究的结果，这表明违反动词时态（“上周日文森特油漆他的乡村别墅的窗框。“）与动词时态正确的句子相比，引起更大的左前否定（局域网）。语义分析最后结合了计算，统一为基础的解析模型，提供ERP数据的功能帐户。
This article investigates how linguistic expressions of time-in particular, temporal adverbs and verb tense morphemes-are used to establish temporal reference at the level of brain physiology. First, a formal semantic analysis of tense and temporal adverbs is outlined. It is argued that computing temporal reference amounts to solving a constraint satisfaction problem. Next, the results of an event-related potential (ERP) study are presented, which suggest that violations of verb tense ("Last Sunday Vincent paints the window frames of his country house.") evoke larger left-anterior negativities (LANs) compared to sentences in which verb tense is correct. The semantic analysis is finally combined with a computational, unification-based model of parsing to provide a functional account of the ERP data.
