摘 要:目的比较阂上和闽下情绪的Slroop效应。方法通过网上发帖的形式招募52名在校大学生,分别使用阈上(30名被试)和阈下(20名被试)壁现的方法,比较了不同情绪条件下,个体对图片的颜色判别任务的反应时和正确率。结果①在阈上呈现条件下,被试在不同图片内容条件下的反应时有显著差异(F(4.116)=3.63,P=0.008),高唤醒正性[(781±60)ms]和负性[(787±63)ms]条件下的反应时都比中性[(733±62)ms]条件下长;②在阈上条件下,唤醒度在反应时上的丰效应显著,(F(1.29)=5.14,P=0.031),高唤醒[(784±59)ms]图片条件下的反啦时大于低唤醒[(761±55)ms]图片下的反应时;⑧在阈下呈现条件下,被试在不同图片内容条件下的反应时有显著差肆(F(4.84)=2.50,P=0.049),低唤醒正性[(661±52)ms]和负。陀[(667±56)ms]条件下的反应时都比中性[(633±49)ms]条件下长;④在闽下呈现条件下,唤醒度在反应时七的主效应显著(F(1.20)=9.97,P=0.005),低唤醒[(664±51)ms]条件F的反应时大于高唤醒[(638±50)ms]下的反心时。结论闽上和阈下情绪Stroop效应可能反映了不同的心理机制。Objective To investigate and compare mechanisms underlying supraliminal and subliminal emotional Stroop effects. Methods 52 college students were recruited to distinguish the color of each emotional picture,which was either supraliminal ( 30 students) or subliminally (22 students) presented to the students ; and their reaction time(RTs) and accuracy(ACC) in each condition were assessed. Results (1)In supraliminal task, the main effect of emotion on RT was significant(F(4.116) = 3.63, P = 0. 008 ) , such that RT in high arousing positive ( ( 781 ± 60) ms) and negative ( ( 787 ± 63 ) ms) conditions were larger than those in neutral( (733 ± 62 ) ms) condition; (2)In supraliminal task,the main effect of arousal on RT was significant(F(F(1.29) = 5.14, P = 0. 031 ) , such that RT in high arousing( (784±59 ) ms) conditions were larger than those in low arousing( (761 ± 55 ) ms) conditions ; (3)In subliminal task, the main effect of emotion on RT was significant (F(4.84)〈 = 2.50, P = 0.049 ) , such that RT in high arousing positive ( ( 661 ± 52 ) ms) and negative ( ( 667 ± 56 ) ms) conditions were larger than those in neutral( (633 ± 49) ms) condition. (4) In subliminal task, the main effect of arousal on RT was significant (F(1,21) = 9.97, P = 0. 005 ) , such that RT in low arousing ( ( 664 ± 51 ) ms) eonditions were larger than those in high arousing( (638 -50)ms) conditions. Conelusion Supraliminal and subliminal emotional Stroop effects may be involved in different mechanisms.
