摘要： The present study used magnetoencephalographic neuroimaging to examine the neural correlates supporting the processing of a negative polarity item (NPI) (renhe) in Mandarin Chinese. Participants monitored the appearance of a catch word in sentences while their brain activities during the processing of the NPI or a perfective aspect marker (-le) were recorded. The results revealed that the NPI in a non-downward entailing context elicited a larger M350 component, possibly reflecting the cost of semantic integration. As a contrast, sentences violating grammatical aspects elicited greater brain responses in a later time window between 500 and 600 ms. The present findings not only demonstrate a clear distinction between semantic and syntactic processing in dissociable time courses, but further indicate that the processing of negative polarity items in Chinese is mainly constrained by the conditions imposed by semantic context. ► The processing of negative polarity items and aspect markers was examined via MEG. ► Mandarin Chinese, instead of Indo-European languages, was employed as stimuli. ► Violation of negative polarity items caused a larger M350 in the left temporal sensors. ► Violating aspect agreement caused larger responses 500–600 ms after the word onset. ► Processing negative polarity items in Chinese is constrained by semantic factors. 出版者： Elsevier Ltd 出版日期： 2013-03 出處： Journal of neurolinguistics, 2013-03, Vol.26 (2), p.258-270 版權： 2012 Elsevier Ltd 識別號： ISSN: 0911-6044 識別號： EISSN: 1873-8052 識別號： DOI: 10.1016/j.jneuroling.2012.09.002
