Distinct P200, N400, and P600 also manifested between noun and noun-verb-ambiguous-word processing, but not between verb and noun-verb-ambiguous-word processing. Results showed significantly distinct ERP components of P200, N400, and P600 between noun and verb processing in native speakers, indicating that semantic factors are essential for the differentiated neural mechanisms behind noun and verb processing. The experiment used Chinese sentences in the configuration of noun phrase + (“not/no”) + noun/verb/noun-verb-ambiguous-word, which excluded grammatical or syntactic factors that could hint at the lexical categories of sentence-final target words. This paper conducted an event-related potential (ERP), sentence comprehension experiment as an attempt to resolve this issue. Neural mechanisms behind noun and verb processing during the course of language comprehension are ubiquitously separate, yet it remains highly controversial as to which factor, syntax or semantics, should be responsible for this separation. 6Department of Linguistics and Translation, School of International Studies, Zhejiang University, Hangzhou, China.5Educational Testing Service, Princeton, NJ, United States.4Center for Linguistics and Applied Linguistics, Guangdong University of Foreign Studies, Guangzhou, China.3Zhejiang Key Laboratory for Research in Assessment of Cognitive Impairments, Hangzhou, China.2Center for Cognition and Brain Disorders, Hangzhou Normal University, Hangzhou, China.1Institutes of Psychological Sciences, Hangzhou Normal University, Hangzhou, China.
