调查种族圈内人之团体和外集团成员的不对称的 neurocognitive 表示，在脸与积极或否定的感情方面的连接被告知以后，我们在一项感性的任务记录了事件相关的潜力(ERP ) 当着面。感情方面的连接 priming 没影响 ERP 当着种族外集团面。相对积极感情方面的连接 priming，然而，否定感情方面的连接 priming 增加了早正面的否定性(N100 ) 和后面的中央否定性的振幅，但是减少一个晚积极的潜力的振幅用种族圈内人之团体脸得到了。而且， N100 振幅与对种族圈内人之团体脸的否定态度的度相关。调查结果建议多重水平的神经机制涉及异构的种族圈内人之团体脸的赋予个性。

英文摘要：

To investigate asymmetric neurocognitive representation of ethnic in-group and out-group members, we recorded event-related potentials （ERPs） to faces in a perceptual task after the faces had been primed with positive or negative affective links. The affective link priming did not influence the ERPs to ethnic out-group faces. However, relative to the positive affective link priming, the negative affective link priming increased the amplitudes of an early frontal negativity （N100） and a following central negativity but decreased the amplitude of a late positive potential elicited by ethnic in-group faces. Moreover, the N100 amplitude correlated with the degree of negative attitudes towards ethnic in-group faces. The findings suggest that multiple-level neural mechanisms are involved in individuation of heterogeneous ethnic in-group faces.
