Power is known to promote effective goal pursuit, especially when it requires one to overcome distractions or bias. We proposed that this effect involves the ability to engage and implement cognitive control. In Study 1, we demonstrated that power enhances behavioral performance on a response conflict task and that it does so by enhancing controlled processing rather than by reducing automatic processing. In Study 2, we used an event-related potential index of anterior cingulate activity to test whether power effects on control were due to enhanced conflict sensitivity or action implementation. Power did not significantly affect neural sensitivity to conflict; rather, high power was associated with a stronger link between conflict processing and intended action, relative to low power. These findings suggest a new perspective on how social factors can affect controlled processing and offer new evidence regarding the transition between conflict detection and the implementation of action control.
权力已知可以促进有效的目标追求，尤其是在需要克服干扰或偏见时。我们提出，这种效果涉及到参与和实施认知控制的能力。在研究 1 中，我们证明了权力可以增强反应冲突任务的行为表现，而且它是通过增强受控处理而不是通过减少自动处理来实现的。在研究 2 中，我们使用前扣带皮层活动的事件相关电位指数来测试权力对控制的影响是否归因于增强的冲突敏感性或动作执行。权力并没有显著影响神经对冲突的敏感性；相反，与低权力相比，高权力与冲突处理和预期动作之间的联系更强。这些发现为社会因素如何影响受控处理提供了新的视角，并为冲突检测与动作控制实施之间的转变提供了新的证据。
