The present study examined the locus responsible for the effect of emotional state on sentence processing in healthy native speakers of Japanese, using event-related brain potentials. The participants were induced into a happy, neutral, or sad mood and then subjected to electroencephalogram recording during which emotionally neutral sentences, including grammatical sentences (e.g. window-NOM close vi, 'The window closes.'), morphosyntactically-violated sentences (e.g. window-ACC close vi, Lit. 'Close the window.'), and semantically-reversed sentences (e.g. window-NOM close vt, 'The window closes pro.') were presented. The results of the ERP experiment demonstrated that while the P600 effect elicited by morphosyntactic violation was not modulated by mood, the P600 effect elicited by semantic reversal anomaly was observed only in participants previously induced into a happy mood. The LAN and N400 were not sensitive to the participants' transient emotional state. These results suggest intact memory access and impaired integration of syntactic and semantic information in individuals in a sad mood.
本研究利用事件相关脑电位，考察了在以日语为母语的健康受试者中，情绪状态对句子加工产生影响的责任脑区。参与者被诱导进入快乐、中性或悲伤情绪，然后在脑电图记录过程中，向他们呈现情感中性的句子，包括符合语法的句子（例如“窓が閉まる”，即“窗户关上”）、形态句法违反的句子（例如“窓を閉まる”，字面意思为“关上窗户”）和语义颠倒的句子（例如“窓が閉める”，即“窗户关上某人”）。ERP实验结果表明，虽然形态句法违反引发的P600效应不受情绪调节，但语义颠倒异常引发的P600效应仅在先前被诱导进入快乐情绪的参与者中观察到。LAN和N400对参与者的瞬时情绪状态不敏感。这些结果表明，悲伤情绪个体的记忆提取完整，但句法和语义信息的整合受损。
