摘　　要：目的:探讨高特质愤怒个体对负性情绪刺激注意偏向的潜在机制。方法:采用同中选异实验范式,以高、低特质愤怒大学生各24名为被试,对比分析高、低特质愤怒被试在中性干扰刺激中搜索情绪靶刺激(注意敏感)及在情绪干扰刺激中搜索中性靶刺激(注意锁定)反应时的差异。结果:重复测量方差分析发现,注意敏感实验中,以11、19张中性面孔为干扰刺激时,皆存在靶刺激主效应及靶刺激与组别交互效应,进一步分析发现,高特质愤怒被试对愤怒面孔为靶刺激的反应时皆显著短于以快乐面孔为靶刺激的反应时。注意锁定实验中,以11、19张情绪面孔为干扰刺激时,皆存在干扰刺激主效应及干扰刺激与组别的交互效应,进一步分析发现,11张情绪面孔为干扰刺激时,高特质愤怒被试以愤怒面孔为干扰刺激的反应时显著长于以快乐面孔为干扰刺激的反应时,以19张情绪面孔为干扰刺激时,两组被试以愤怒面孔为干扰刺激的反应时皆显著长于以快乐面孔为干扰刺激的反应时。结论:高特质愤怒者对威胁性刺激的警觉——锁定是其对威胁性刺激产生注意偏向的潜在原因。Objective： To investigate potential mechanism of high trait anger individuals＇ attentional bias to negative emotional stimulus.Methods： 24 high trait anger college students and 24 low ones were selected as subjects.Odd-one-out search task was selected to compare the differences of reaction time of the two groups while searching emotional stimulus in neutral distracters and searching neutral target stimulus in emotional distracters.Results： It was shown by Repeated Measurement ANOVA that main effect（F=37.701,P=0.000） in target stimulus and interaction effect between groups and target stimulus were found in attentional sensitivity trials while 11 neutral facial expressions were used as distracters.Further analysis showed the reaction time of high trait anger subjects to angry facial expression target was shorter than to happy facial expression target.Main effect（F=95.553,P=0.000） in target stimulus and interaction effect between groups and target stimulus were also found in attentional sensitivity trials while 19 neutral facial expressions were used as distracters.Further analysis showed the reaction time of high trait anger subjects to angry facial expression target was shorter than to happy facial expression target in distracters stimuli and interaction effect between groups and distracters stimuli were found in attentional fixation trials while 11 emotional facial expressions were used as distracters.Further analysis showed the reaction time of high trait anger subjects while angry facial expression distracters was longer than while happy facial expression distracters.Main effect（F=26.781,P=0.000） in distracters stimuli and interaction effect between groups and distracters stimuli were found in attentional fixation trials while 19 emotional facial expressions were used as distracters.Further analysis showed the reaction time of high and low trait anger subjects while angry facial expression distracters was longer than while happy facial expression distracters.Conclusion： It is potential cau
