Abstract

Electrophysiological techniques were used to assess the generalizability of concreteness effects on word processing across word class (nouns and verbs) and different types of lexical ambiguity (syntactic only and combined syntactic/semantic). The results replicated prior work in showing an enhanced N400 response and a sustained frontal negativity to concrete as compared with abstract nouns. The effect of concreteness on the N400 generalized to all word class and ambiguity conditions, whereas the frontal effect was present for all word types except for the syntactically and semantically ambiguous items when these were used as verbs. The seemingly dissociable ERP effects of concreteness at frontal and central/posterior electrode sites revealed by these data suggest that concreteness may impact multiple aspects of neurocognitive processing.

摘要

采用电生理技术评估具体性效应在不同词性(名词和动词)以及不同类型词汇歧义(仅句法歧义和句法/语义组合歧义)情况下对词汇加工的普遍性。结果重复了之前的研究,即与抽象名词相比,具体名词会增强N400反应并持续出现额部负波。具体性对N400的影响在所有词性和歧义条件下都具有普遍性,而额部效应在除句法和语义都有歧义的词项用作动词时之外的所有词类中都存在。这些数据揭示的额部和中央/后部电极部位具体性效应在事件相关电位上看似可分离,表明具体性可能会影响神经认知加工的多个方面。
