非任务相关条件下社会权力对愤怒表情加工的影响

之前的研究表明权力能够影响愤怒表情的加工,但是并不清楚当愤怒刺激是非目标任务刺激时(非任务相关条件下),权力是否影响以及如何影响愤怒表情的加工。本研究采用事件相关电位技术,首先操纵情绪观察者(被试)和情绪表达者(目标)的权力水平(高vs.低),之后采用修正的oddball范式考察当愤怒刺激是非目标任务刺激时,情绪观察者和表达者的权力水平对愤怒情绪加工的影响。行为结果表明,与高权力个体相比,低权力个体在识别年老面孔目标时成绩更低。脑电结果发现,与高权力个体相比,低权力个体对中性目标刺激和愤怒的非目标刺激均产生了更强的N170波幅,表现出更强的敏感性。该研究结果说明,高权力个体的行为成绩优于低权力个体的行为成绩,即使在非任务相关条件下,与高权力个体相比,低权力个体对愤怒情绪刺激的早期敏感性仍然更强。

The influence of power on anger expression under task-irrelevant condition

The experiment used two factors (individual power: high, low) × 2 (target power: high, low) design to explore the effect of power on anger faces. Using FaceGen Modeller software, we generated 12 faces of Southeast Asian males as raw materials, and the standard stimulus is the 43-year-old neutral expression face, the 65-year-old neutral face is a target deviation stimulus and the 43-year-old angry face is a non-target deviation stimulus. The experiments were divided into three steps. First, the individual power are manipulated by requiring the participants to recall and write down their experiences of being controlled or controlled by others. Secondly, the target power are manipulated. Finally, completed the oddball task. In conclusion, the findings of the present study suggest that, compared with individuals with low-power, individuals with high-power (1) are more perceptually sensitive to identify neutral face targets; (2) have weaker N170 amplitudes for both neutral target stimulation and angry non-target stimulation, which supports the sensitivity bias. The results of this study indicate that when the anger stimulus is a non-target task-related stimulus, the individual's power still affects the individual's early sensitive processing of the anger stimulus.
