本文提出了一个ERP实验研究的基本性质的语义表征的有生命和无生命的物体。时间锁定ERP签名的视觉刺激的发作,我们发现拓扑结构的相似性,在有生命和无生命的物体处理。此外,当映射更一般的更具体的表示(听觉视觉刺激),我们发现之间的动画和动画中的N400振幅也没有差异。本研究进一步证实了单一语义组织理论,但不支持基于特征的分离概念组织预测。令人惊讶的是,还发现,P600的成分,这是迄今为止,主要是与句法加工是一个敏感的指标的概念加工。关于P600成分的最明显的差异被发现之间有生命和无生命的比赛,从而有生命的比赛引起更多的积极ERP签名相比,无生命的比赛。
This paper presents an ERP experiment examining the underlying nature of semantic representation of animate and inanimate objects. Time-locking ERP signatures to the onset of visual stimuli we found topological similarities in animate and inanimate object processing. Moreover, when mapping more general to more specific representation (auditory to visual stimuli) we found no difference between animates and in animates in the N400 amplitude either. This study provides further evidence for the theory of unitary semantic organization, but no support for the feature-based prediction of segregated conceptual organization. Surprisingly, it was also found that the P600 component, which has been thus far mostly related to syntactic processing to be a sensitive index of conceptual processing. The most apparent difference regarding P600 component was found between animate and inanimate matches, whereby animate matches elicited more positive ERP signatures in comparison to inanimate matches.
