Event-related brain potentials (ERPs) were used to examine the neural correlates of proactive and reactive cognitive control within the context of the Dual Mechanisms of Control theory. Individuals performed the counting Stroop task and the proportion of congruent and incongruent trials was varied across blocks. The Stroop effect was smaller in the mostly incongruent block than in the mostly congruent block. The ERP data revealed a double dissociation between the medial frontal negativity (MFN) and the medial posterior negativity (MPN), where the amplitude of the MFN was greater in the mostly incongruent block and the amplitude of the MPN was greater in the mostly congruent block. The ERP data also revealed slow wave activity that distinguished the mostly incongruent and mostly congruent blocks. These findings support the idea that different regions of the cingulate and anterior frontal cortex underpin proactive and reactive control.
事件相关脑电位（ERPs）被用来研究双机制控制理论背景下主动和被动认知控制的神经相关性。个体执行计数斯特鲁普任务，并且在块之间变化一致和不一致试验的比例。在主要不一致块中，斯特鲁普效应比在主要一致块中更小。ERP 数据揭示了内侧额负波（MFN）和内侧后负波（MPN）之间的双重分离，其中主要不一致块中的 MFN 幅度更大，主要一致块中的 MPN 幅度更大。ERP 数据还揭示了区分主要不一致和主要一致块的慢波活动。这些发现支持这样一种观点，即扣带和额前皮质的不同区域支持主动和被动控制。
