Abstract
An experiment was conducted to examine the difference between noun and verb words using ERP measurements and lexical decision task. Results showed that there is significant interaction between word class and word-concreteness between 200300, 300400ms in lateral sites. Concrete nouns were associated with a more negative ERP than concrete verbs in the two hemispheres. Furthermore, there is significant interaction between word class and electrode site between 300400ms. ERP differences between nouns and verbs are primarily over frontal lobe and temporal lobe. Our results partly support neurobiological theory of language representation.
Keywords: | nouns; verbs; ERP; neurobiological theory of language representation |
