Semantic reversal anomalies (SRAs)—sentences where an implausibility is created by reversing participant roles—have attracted much attention in the literature on the electrophysiology of language. In spite of being syntactically well formed but semantically implausible, these sentences unexpectedly elicited a monophasic P600 effect in English and Dutch rather than an N400 effect. Subsequent research revealed variability in the presence/absence of an N400 effect to SRAs depending on the language examined and the choice of verb type in English. However, most previous studies employed the same presentation modality (visual) and task (acceptability judgement). Here, we conducted two experiments and three statistical analyses to investigate the influence of stimulus modality, task demand and statistical choices on event‐related potential (ERP) response patterns to SRAs in English. We reproduced a previous study's procedure and analysis (N. Bourguignon et al. (2012) Brain and Language , 122, 179–189) and further introduced between‐subjects factors of task type and modality, using mixed‐effects modelling to analyse the data. We observed an N400 effect to typical English SRAs (agent subject verbs, e.g. “the fries will eat the boys”), which contrasts existing literature and was not predicted by existing theories that account for SRA processing. Task demand modulated the ERPs elicited by SRAs, while auditory presentation led to increased comprehension accuracy and a more broadly distributed ERP. Finally, the statistical methods used influenced the presence/absence of ERP effects. Our results suggest a sensitivity of language‐related ERP patterns to methodological parameters, and we conclude that future experiments should take this into careful consideration.

显微镜下的语义反转异常:任务和情态对与语言相关的事件相关电位的影响

语义反转异常(SRA)是通过反转参与者角色而造成不可信的句子,在语言的电生理学方面引起了人们的广泛关注。尽管这些句法在语法上结构良好,但在语义上令人难以置信,但它们意外地在英语和荷兰语中引起了单相P600效应,而不是N400效应。随后的研究表明,是否存在N400对SRA的影响取决于所检查的语言和英语中的动词类型选择。但是,以前的大多数研究都采用相同的呈现方式(视觉)和任务(可接受性判断)。在这里,我们进行了两个实验和三个统计分析,以研究刺激方式的影响,任务需求和英语对SRA的事件相关电位(ERP)响应模式的统计选择。我们转载了先前研究的程序和分析(N. Bourguignon等人(2012年)(Brain and Language,122,179–189),并进一步引入了任务类型和情态的主体间因素,使用混合效应模型来分析数据。我们观察到N400对典型的英语SRA(代理主语动词,例如“炸薯条会吞噬男孩”)的影响,这与现有文献形成对比,而现有的理论并未预测到SRA处理的结果。任务需求调节了SRA引发的ERP,而听觉呈现则提高了理解的准确性,并使ERP分布更加广泛。最后,所使用的统计方法影响了ERP效果的存在与否。我们的结果表明与语言相关的ERP模式对方法参数的敏感性,并且我们得出结论,未来的实验应对此进行仔细考虑。
