研究表明，种族分类是缓慢的类别不一致的信息的存在。目前的实验测试了反应冲突，或相反的反应倾向竞争激活的趋势，作为这种效应的机制。在两个实验中，参与者更快地分类的面孔两侧的种族刻板印象一致的话比面孔两侧的刻板印象不一致的话，特别是当刻板印象一致的话更有可能。事件相关电位（ERP）数据表明，这种行为效应是由于反应冲突。侧化准备电位（LRP）表明，相对于刻板印象一致的侧翼，刻板印象不一致的侧翼最初引起激活的不正确的分类反应，这减缓了激活和执行的正确的分类反应。刻板印象不一致的侧翼也增强了N2（冲突监测）组件的幅度。刺激评价时间的潜在差异，评估与ERP的P3组件的潜伏期，不负责观察到的反应时间差异。研究结果进行了讨论的神经位点的行为影响。
Research indicates that racial categorization is slowed by the presence of category-inconsistent information. The current experiments tested response conflict, or the tendency for opposing response tendencies to compete for activation, as a mechanism for this effect. In two experiments, participants more quickly categorized faces flanked by racial stereotype-congruent words than faces flanked by stereotype-incongruent words, particularly when stereotype-congruent words were more probable. Event-related potential (ERP) data indicated that this behavioral effect was due to response conflict. The lateralized readiness potential (LRP) showed that, relative to stereotype-congruent flankers, stereotype-incongruent flankers initially elicited activation of the incorrect categorization response, which slowed activation and execution of the correct categorization response. Stereotype-incongruent flankers also enhanced the amplitude of the N2 (conflict monitoring) component. Potential differences in stimulus evaluation time, assessed with the latency of the P3 component of the ERP, were not responsible for observed response time differences. Findings are discussed in terms the neural locus of behavioral effects.
