摘要目的 探究情绪的唤醒度在情绪Stroop效应中的作用.方法 通过网上发帖的形式招募27名在校大学生,比较不同情绪条件下,被试对图片的颜色判别任务的反应时和正确率.结果 ①被试在不同图片内容条件下反应时的主效应达到显著(F(5.130)=5.90,P＜0.01),正性图片[(893±36)ms]和负性图片[(866±36)ms]条件下的反应时都比中性[(828±43)ms]条件下长;②被试在不同图片内容条件下正确率的主效应达到临界显著(F(5.130)=2.63,P=0.05),负性高唤醒图片条件下的正确率(0.92±0.03)低于颜色方块条件下的正确率(0.95±0.02);③愉悦度的主效应在反应时上显著(F(1.26)=7.03,P=0.013),正性图片的反应时[(893±36)ms]大于负性图片的反应时[(866±36)ms];④唤醒度的主效应在正确率上显著(F(1.26)=5.63,P=0.025),高唤醒图片的正确率(0.93±0.17)小于低唤醒图片的正确率(0.95±0.09).结论 情绪Stroop效应可能更多地受到情绪刺激的唤醒度的影响.

abstractsObjective To investigate the arousal effect in the emotional Stroop effect by systematically manipulating the valence and arousal of affective stimuli.Methods 27 college students were recruited to distinThe main effect of emotion on RT was significant (F(5.130) = 5.90, P ＜ 0.01 ), RTs in positive (( 893±36 ) ms)main effect of Emotion on ACC was marginally significant (F(5.130) = 2.63, P = 0.05 ), ACC in high arousing negalence on RT was significant (F(1.26 = 7.03, P =0.013 ).Further analysis revealed that RTs in positive condition was significant (F(1.26) =5.63, P=0.025),ACC in high arousing condition (0.93 ±0.17) was lower than ACC in low arousing condition (0.95 ± 0.09 ).Conclusion The emotional Stroop effect mainly depends on the arousal information of affective stimuli.
