关于认知控制的一个被忽视的问题是控制过程如何检测需要它们参与的情况。作者在此提出，可以通过监控信息处理中的冲突来部分评估控制需求。这一假设得到了有关前扣带皮层的数据的支持，前扣带皮层是一个涉及认知控制的大脑区域，它似乎也对冲突的发生做出反应。本文报告了两项计算模型研究，旨在阐明冲突监控假设并检验其含义。第一项研究测试了该假设是否足以解释大脑激活数据，将冲突测量应用于现有的涉及前扣带回的任务模型。第二项研究实现了一个将冲突监控与认知控制连接起来的反馈循环，用它来模拟许多重要的行为现象。
A neglected question regarding cognitive control is how control processes might detect situations calling for their involvement. The authors propose here that the demand for control may be evaluated in part by monitoring for conflicts in information processing. This hypothesis is supported by data concerning the anterior cingulate cortex, a brain area involved in cognitive control, which also appears to respond to the occurrence of conflict. The present article reports two computational modeling studies, serving to articulate the conflict monitoring hypothesis and examine its implications. The first study tests the sufficiency of the hypothesis to account for brain activation data, applying a measure of conflict to existing models of tasks shown to engage the anterior cingulate. The second study implements a feedback loop connecting conflict monitoring to cognitive control, using this to simulate a number of important behavioral phenomena.
