尾侧前扣带皮层（cACC）被认为参与了性能监控，因为冲突和错误相关的活动经常共同定位在这个区域。最近的研究结果表明，这些影响可能是差异调制的意识。为了阐明意识在cACC性能监测中的作用，我们使用快速事件相关功能磁共振成像检查cACC活动，而受试者执行双重任务：延迟识别任务和串行响应任务（SRT）与隐式概率学习规则（即刺激位置遵循受试者不知道的概率序列）。任务表现证实了位置序列是隐性学习的。尽管我们没有发现意识到序列存在的证据，但成像数据显示，相对于刺激遵循序列（低冲突）的试验，在违反序列（高冲突）的正确试验期间，cACC活性增加。意识上的错误也会激活同一个大脑区域。这些结果表明，cACC的性能监测功能超出了有意识或无意识的错误检测，并涉及检测多个响应，即使他们是意识之外。
The caudal anterior cingulate cortex (cACC) is thought to be involved in performance monitoring, as conflict and error-related activity frequently co-localize in this area. Recent results suggest that these effects may be differentially modulated by awareness. To clarify the role of awareness in performance monitoring by the cACC, we used rapid event-related fMRI to examine the cACC activity while subjects performed a dual task: a delayed recognition task and a serial response task (SRT) with an implicit probabilistic learning rule (i.e. the stimulus location followed a probabilistic sequence of which the subjects were unaware). Task performance confirmed that the location sequence was learned implicitly. Even though we found no evidence of awareness for the presence of the sequence, imaging data revealed increased cACC activity during correct trials which violated the sequence (high conflict), relative to trials when stimuli followed the sequence (low conflict). Errors made with awareness also activated the same brain region. These results suggest that the performance monitoring function of the cACC extends beyond detection of errors made with or without awareness, and involves detection of multiple responses even when they are outside of awareness.
