摘　　要：目的探讨正/负性视觉刺激对微表情识别能力的影响。方法招募90名志愿者,实验采用被试内设计,正负性两个情绪刺激水平,将被试者随机分成3组,即实验组(正性视觉刺激组和负性视觉刺激组)和对照组。结果微表情识别能力前测视觉刺激组和对照组差异无统计学意义(F=0.153,P>0.05);后测视觉刺激组与对照组的得分差异有统计学意义(F=15.300,P<0.01);正性视觉组与负视觉组(t=0.49,P<0.01),正性视觉组与对照组(t=0.41,P<0.01),负性视觉组与对照组(t=0.48,P<0.01)得分差异有统计学意义。结论视觉刺激对微表情识别能力有影响,正性视觉刺激对被试的微表情识别能力有促进作用。Objective To explore the effect of positive/negative visual stimulationon the micro expression recogni- tion. Methods A total of 90 volunteers were recruited and randomly divided into experimental groups （a positive visual stimulation group and a negativevisual stimulation group） and a control group, and this research was performed by usiugthe within-subject design. Results Before the experiment, there was no significant difference among the positive/negative vi- sual stimulation group and control group in the micro-expressions recognition ability scores （F= 0.153, P〉 0.05）. After the experiment, in the micro-expressions recognition ability scores,there was a significant difference among the positive/negative visual stimulation group and control group （F =15.300, P〈0.01）,between the positive and negative visual groups （t=0.49 , P〈0.01）, the positive visual group and control group （t = 0.41, P〈0.01）, and the negative visual group and control group （t = 0.48, P〈0.01）, respectively, and the positive visual stimulation significantly enhanced the micro-expressions recognition a- bility. Conclusion The visual stimulation has an influence on the micro-expressions recognition ability, and the positive visual stimulation can significantly enhance the micro-expressions recognition ability.
