在两个事件相关电位(ERP)的实验中,我们确定在何种程度上格莱斯的格言的信息量以及语用能力有助于增加建立的句子意义,通过检查的影响,信息不足与信息标量语句(例如“有些人有肺/宠物,和.”)上的N400事件相关电位(ERP),语义处理的电生理指标。在实验1中,只有语用技能的参与者(自闭症商数通信分量表索引)显示了较大的N400信息不足的语句。在实验2中,当关键词不集中时,这种效应消失,从而忽略了局部信息不足(例如,“有些人的肺......”)。我们的研究结果表明,虽然语用标量意义可以逐步有助于句子的理解,这种贡献是依赖于上下文的因素,无论这些是来自个人的语用能力或整体的实验背景。
In two event-related potential (ERP) experiments, we determined to what extent Grice’s maxim of informativeness as well as pragmatic ability contributes to the incremental build-up of sentence meaning, by examining the impact of underinformative versus informative scalar statements (e.g. “Some people have lungs/pets, and…”) on the N400 event-related potential (ERP), an electrophysiological index of semantic processing. In Experiment 1, only pragmatically skilled participants (as indexed by the Autism Quotient Communication subscale) showed a larger N400 to underinformative statements. In Experiment 2, this effect disappeared when the critical words were unfocused so that the local underinformativeness went unnoticed (e.g., “Some people have lungs that…”). Our results suggest that, while pragmatic scalar meaning can incrementally contribute to sentence comprehension, this contribution is dependent on contextual factors, whether these are derived from individual pragmatic abilities or the overall experimental context.
