事件相关功能磁共振成像和一个版本的斯特鲁普颜色命名任务被用来测试两个相互冲突的理论前扣带皮层（ACC）的功能在执行过程中的认知。当战略进程较少参与和冲突高时，行政协调会活动的响应增加，但当战略进程参与和冲突减少时，则不是这样。这与广泛持有的观点不一致，即ACC实施战略过程以减少认知冲突，例如反应竞争。相反，它表明，ACC服务的评价功能，检测认知状态，如反应竞争，这可能会导致业绩不佳，并代表的知识，战略过程需要参与。
Event-related functional MRI and a version of the stroop color naming task were used to test two conflicting theories of anterior cingulate cortex (ACC) function during executive processes of cognition. A response-related increase in ACC activity was present when strategic processes were less engaged, and conflict high, but not when strategic processes were engaged and conflict reduced. This is inconsistent with the widely held view that the ACC implements strategic processes to reduce cognitive conflicts, such as response competition. Instead, it suggests that the ACC serves an evaluative function, detecting cognitive states such as response competition, which may lead to poor performance, and representing the knowledge that strategic processes need to be engaged.
