An ERP Study on Chinese-English Bilinguals’ Processing of En

发布时间：2021-06-11 22:31

　　情感词加工在语言理解过程中至关重要,因此对情感词的研究是心理语言学和神经语言学研究的重点。人们通过对情感词语义及正性,负性,中性情感色彩的把握从而了解整个句子或文章的含义。Bradley等人采用9点量表建立一套根据愉悦度,唤醒度和熟悉度来评定的英语情感词库,目前被广泛采用。在中国,王一牛和罗跃嘉等人采用同样的办法,结合中国的文化和习惯,编制了汉语情感词库,对汉语情感材料进行了愉悦度,唤醒度,优势度和熟悉度四个维度的评定。以往的研究都只采用一种语言的情感词作为刺激材料,受试也都是本族语者。采用ERP技术手段的试验结果表明正性词引发的N400波幅小于负性词和中性词,因为正性材料被认为有更好的语义整合。然而LPP波幅情况,研究并不一致。本研究以汉英双语者为受试,14名受试均为光电学院在校大三男生,英语及其对应的汉语情感词同时作为刺激材料,让受试判定所呈现的刺激是真词还是假词,同时记录其脑电波,旨在分析汉英双语者对英汉情感词加工的特点。实验结果表明:1.在英语情感词内部,N400波幅正性词小于负性词和中性词,和前人结果一样。LPP波幅情况本实验支持效价驱动加工,即正性词引发的LPP波幅大于负性...
