本实验利用事件相关脑电位（event- correlation brain potentials, ERPs）研究了冲突在反应分类系统和评价分类系统中对情感一致性效应的影响。参与者完成了一个启动评估决策任务，其中一致与不一致试验的比例被操纵。情感一致性效应的大小随一致性试验的比例增加而增加。ERP数据确定了这一效应在反应系统中的位置：侧化准备电位（LRP）显示，在启动启动后，运动皮层发生优先反应激活；额中央N2（冲突监测）成分表明，当启动启动的反应与目标反应不同时，冲突就会发生，而不管启动反应和目标反应的情感一致性如何。这种冲突的程度随启动物的策略加工而变化，因为参与者对可能引发冲突的启动物的注意力较少。这些数据支持评价决策任务中情感一致性效应的反应冲突解释，并表明注意力的战略控制在决定冲突发生的程度方面是重要的。
This experiment investigated the role of conflict in the response and evaluative categorization systems in the affective congruency effect using event-related brain potentials (ERPs). Participants completed a primed evaluative decision task in which the proportion of congruent to incongruent trials was manipulated. The size of the affective congruency effect increased along with the proportion of congruent trials. ERP data identified the locus of this effect in the response system: the lateralized readiness potential (LRP) showed that preferential response activation occurred in motor cortex following prime onset, and the fronto-central N2 (conflict monitoring) component indicated that conflict occurred when the response activated by the prime differed from the target response, irrespective of the affective congruency of the prime and target. The extent of this conflict covaried with strategic processing of primes, as participants directed less attention to primes that were likely to elicit conflict. These data support a response conflict account of affective congruency effects in the evaluative decision task and indicate that strategic control of attention is important in determining the extent to which conflict occurs.
