摘　　要：目的:探讨阈下呈现启动图片时是否存在情绪启动效应,分析阈下情绪启动中是否存在负性偏向。方法:采用阈下呈现启动图片的方式,要求大学生尽快对目标图片做出正负性的判断。采用重复测量ANOVA分析,比较大学生在不同的情绪启动条件下、对正负性图片的反应正确率和平均反应时的差异。结果:不同情绪启动条件、目标图片的性质对反应正确率和平均反应时均存显著主效应,启动条件和控制条件的反应正确率显著高于非启动条件,而平均反应时则显著短于非启动条件;受试对负性图片的反应正确率显著高于正性图片,对负性图片平均反应时则显著短于正性图片。结论:阈下呈现启动图片时可观测到明显的情绪启动效应;在阈下情绪启动中,存在“负性偏向”。Objective： The purpose of this study was to replicate the subliminal priming effect with the affective pictures and compare the reactions to positive target pictures and negative target pictures. Methods： Prime pictures were subliminally presented, and the subjects were required to judge whether the target picture was a positive or a negative one as soon as possible. The correct response rate and the mean response latency were subjected to ANOVA with repeated measures. Results： Significant main effects of target and affective congruence were found for both correct rate and mean response latency. The mean response latency was significantly slower for affectively incongruent trials, as compared to those for affectively congruent trials. The correct rate for affectively incongruent trials was the lowest. Subjects were relatively slower to respond to positive target pictures than to negative target pictures. Conclusion： There are affective priming effects with subliminally presented pictures. There is ＂negativity bias＂ in subliminal affective priming.
