Power is known to promote cognitive processing in a goal‐directed way. However, it is unknown whether powerful individuals invest more resources when pursuing their goals or whether they invest their resources more efficiently. We examined how experiencing high versus low power affects the efficient investment of cognitive resources using electroencephalography (EEG). Specifically, event‐related desynchronization (ERD) in the upper alpha band (10.5–12.75 Hz) was used to quantify the use of cognitive resources during task completion. Results showed that high‐power participants used fewer neural resources compared to low‐power participants across the whole brain but task performance did not differ between groups. These findings demonstrate that, instead of investing more resources, high‐power participants performed the task with greater cognitive efficiency compared to low‐power participants. Performing tasks efficiently could help powerholders deal with their demanding jobs and responsibilities.

心理力量改变认知效率

众所周知，权力可以以目标为导向的方式促进认知处理。然而，尚不清楚有权势的人是否在追求目标时投入了更多资源，还是更有效地投入了资源。我们使用脑电图 (EEG) 研究了体验高功率与低功率如何影响认知资源的有效投资。具体而言，上阿尔法频带（10.5-12.75 Hz）中的事件相关去同步（ERD）用于量化任务完成期间认知资源的使用。结果表明，与低功率参与者相比，高功率参与者在整个大脑中使用的神经资源更少，但各组之间的任务表现没有差异。这些发现表明，与其投入更多资源，与低功率参与者相比，高功率参与者以更高的认知效率执行任务。有效地执行任务可以帮助当权者处理他们要求苛刻的工作和责任。
