Abstract: 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.
