摘　　要：以46名大学生为被试,以不同词性(名词&动词)的汉语双字正性情绪词、负性情绪词、中性词作为刺激材料,考察情绪效价强度(极端、中等、中性)对词性判断加工的影响。结果表明:(1)动词的词性判断比名词难,且该难度会受到高强度情绪信息的影响而扩大。(2)情绪效价及强度对名词加工的影响表现在两个方面:极端正性情绪易化对名词的加工,增强名词加工的优势效应;而中等和极端负性情绪干扰对名词的词性判断,削弱名词加工的优势效应。(3)除了受到性别、性格等因素的影响外,情绪效价强度效应的具体表现还受刺激类型的调制。Considerable research has confirmed the correlation between emotion and cognition,especially the effect of emotion on vocabulary processing.Behavioral studies have shown the negative bias during the process of emotional words,that is to say,an individual pays more attention to the negative words relative to the positive or neutral words.Furthermore,a body of ERP and fMRI studies reveal different brain activation when individuals recognizing negative words and neutral words.All those researches indicate that emotional valence plays an important part in an individual＇s vocabulary processing.In addition,the valence intensity effect of emotional pictures was found in some recent studies,which suggests that word processing may also be affected by emotional valence.According to those results,it seems that the emotional valence and intensity may influence vocabulary processing together.Thus,the present study hypothesizes that Chinese words processing is affected by both emotional valence and emotional intensity,and the effect differs in the emotional words of different parts of speech.As paid volunteers,46 undergraduates（22 males,24 females,mean year=22） from Southwest University participated in the experiment.Using emotional words（positive,negative neutral）of different parts of speech,we aimed to investigate whether the valence intensity will influence the cognitive processing of words＇ speech judgment.The present study adopted a speech judgment task which consisted of 120 words（40 highly positive words,40 moderately positive words and 40 neutral words in the positive experiment,40 highly negative words,40 moderately negative words and 40 neutral words in the negative experiment）.One half of those words were nouns,and the other half were verbs.Three groups of words in each experiment were selected in such a way that they differed significantly in valence from one another,but were similar in arousal.The subjects were assigned in either positive experiment or negative experiment randomly and were instruct
