The present studies evaluated motives associated with the Dark Tetrad traits (Machiavellianism, narcissism, psychopathy, and sadism) using a computerized approach-avoidance conflict task (AACT). Study 1 used an Emoticon AACT with a forced choice between smiley and frowny face icons. In Phase 1, participants (n = 197) were shown a positive image if they chose to move a stick-figure manikin toward the smiley icon, and were shown a negative image if they chose the frowny icon. In Phase 2, they were offered a varying number of points (0, 1, 5, 25, or 50) for choosing the frowny icon. We found that sadism, Machiavellianism, and psychopathy were associated with accepting fewer points to approach the frowny icon that cued a negative image. This same pattern manifested for participants with low empathy levels, particularly when affective resonance was low and affective dissonance was high. Study 2 (n = 191) used an Image AACT where the choice alternatives were positive and negative images, which produced smiley or frowny icons, respectively. Sadism and dissonant emotional tendencies predicted choices directed toward negative images in Phase 2. In Studies 3 (n = 288) and 4 (n = 276), we confirmed our Emoticon AACT findings using gender-balanced samples. Studies 3 and 4 also introduced a viewing-time task (VTT). Sadism and dissonant emotional tendencies predicted decreased viewing times for positive images, but did not predict increased viewing times for negative images, suggesting that negative emotional reactions produced by the positive images were the primary motivating factor in the present AACT. Overall, our findings serve as further evidence of the different motives underlying socially aversive tendencies.
本研究使用计算机化的趋避冲突任务(AACT)评估了与黑暗三性格特质(马基雅维利主义、自恋、精神病态和虐待狂)相关的动机。研究1使用了表情符号AACT,在笑脸和哭脸图标之间进行强制选择。在第一阶段,如果参与者(n = 197)选择将简笔人物模型移向笑脸图标,就会向他们展示一幅正面图像;如果他们选择哭脸图标,则会展示一幅负面图像。在第二阶段,他们因选择哭脸图标而获得不同数量的分数(0、1、5、25或50)。我们发现,虐待狂、马基雅维利主义和精神病态与为接近提示负面图像的哭脸图标而接受更少分数有关。这种相同的模式在同理心水平较低的参与者中表现明显,尤其是在情感共鸣低且情感失调高的时候。研究2(n = 191)使用了图像AACT,其中选择的选项是正面和负面图像,分别产生笑脸或哭脸图标。虐待狂和失调情绪倾向预测了第二阶段针对负面图像的选择。在研究3(n = 288)和研究4(n = 276)中,我们使用性别均衡的样本证实了表情符号AACT的研究结果。研究3和研究4还引入了观看时间任务(VTT)。虐待狂和失调情绪倾向预测了对正面图像的观看时间减少,但没有预测对负面图像的观看时间增加,这表明正面图像产生的负面情绪反应是当前AACT中的主要驱动因素。总体而言,我们的研究结果进一步证明了社会厌恶倾向背后存在不同的动机。
