摘　　要：本研究采用情绪归类任务,通过考察英语二语情绪标签名词和负载名词诱发的脑电变化,探究了两类情绪名词的认知神经模型。研究发现:1)两类情绪名词均比中性名词诱发更大的N100;2)积极标签名词比中性名词诱发更大的EEPN和更小的N400,消极标签名词和负载名词比中性名词诱发更大的LEPN;3)积极标签名词和积极负载名词均比中性名词诱发更大的LPC。据此构建了英语二语情绪名词的三阶段加工模型:早期为感知觉加工阶段,情绪表征促进词形识别;中期为情绪和概念意义加工阶段,标签名词的意义通达早于负载名词且受效价调节;晚期为语境整合阶段,两者均受效价调节。The present study explores the cognitive neural model of L2 English emotion⁃label and emotion⁃laden nouns by examining the changes of their elicited ERPs in an emotion categorization task.Results show that:1)Both emotion⁃label and emotion⁃laden nouns elicite larger N100 than neutral nouns.2)Positive emotion⁃label nouns induce larger EEPN and smaller N400 than neutral nouns,while emotion⁃laden and negative emotion⁃label nouns induce bigger LEPN than neutral nouns.3)Positive emotion⁃label and emotion⁃laden nouns display larger LPC than neutral nouns.Based on these findings,a three⁃stage processing model of L2 emotional nouns is constructed.At the early perceptual processing stage,emotion representation accelerate the morphological recognition of these two types of emotional nouns.At the middle emotional meaning and conceptual meaning processing stage,the semantic access to emotion⁃label nouns occur earlier than that of emotion⁃laden nouns and is modulated by valence.At the late context integration stage,the processings of the two types of emotional nouns are both influenced by valence.
