根据认知控制框架(DMC)的双重机制，老年人主要依赖反应性控制，而不是主动控制。因此，我们预计，相对于任务难度越来越大的年轻人，老年人的反应冲突会更高。在低、中、高难度水平下，分别检查快速反应和慢反应(分别代表主动控制和反应控制)的反应锁定事件相关电位活动。老年人比年轻人更频繁地招募反应性控制，这反映在行为成本增加和反应前负性(PRN)增强。在低难度水平下，冲突检测(额叶内侧负波，MFN)的年龄差异不明显，但在老年人中，反应冲突随着难度的增加而增加。这些数据为DMC提供了经验支持，表明衰老与较低效率的反应控制处理模式有关。
According to the dual-mechanisms of cognitive control framework (DMC), older adults rely predominantly on reactive as opposed to proactive control. As a result, we expected elevated response conflict for older relative to younger adults with increasing task difficulty. Response-locked ERP activity was examined separately for fast and slow responses (representing proactive and reactive control, respectively) at low, medium, and high levels of difficulty. Older adults recruited reactive control more often than the young, as reflected by increased behavioral costs and enhanced pre-response negativity (PRN). No age differences in conflict detection (medial frontal negativity, MFN) were evident at low levels of difficulty, but response conflict increased along with difficulty for older adults. These data provide empirical support for the DMC suggesting that aging is associated with a less efficient reactive-control mode of processing.
