We examined the hypothesis that unintentional race-biased responses may occur despite the activation of neural systems that detect the need for control. Participants completed a sequential priming task that induced race-biased responses on certain trials while electroencephalography was recorded. The error-related negativity (ERN) wave, a component of the event-related potential with an anterior cingulate generator, was assessed to index neural signals detecting the need for control. Responses attributed to race bias produced larger ERNs than responses not attributed to race bias. Although race-biased responses were prevalent across participants, those with larger ERNs to race-biased responses showed higher levels of control throughout the task (e.g., greater accuracy and slowed responding following errors). The results indicate that race-biased responses may be made despite the activation of neural systems designed to detect bias and to recruit controlled processing.
尽管检测控制需求的神经系统被激活，但仍可能出现无意的种族偏见反应。参与者完成了一项序列启动任务，在某些试验中会引发种族偏见反应，同时记录脑电图。错误相关负波（ERN），一种由前扣带回产生的事件相关电位成分，被用来评估检测控制需求的神经信号。归因于种族偏见的反应比不归因于种族偏见的反应产生更大的ERN。尽管种族偏见反应在参与者中普遍存在，但对种族偏见反应有更大ERN的人在整个任务中表现出更高的控制水平（例如，更高的准确性以及错误后反应变慢）。结果表明，尽管旨在检测偏见并调用受控加工的神经系统被激活，但仍可能产生种族偏见反应。
