The other-race effect is the phenomenon that people are better able to recognize and remember faces of their same race. Angry faces have been shown to facilitate processes that promote face recognition as reflected in the proportion of remembered faces after study. The other-race effect may be diminished when other-race faces display negative expressions, but no event-related potential studies have examined whether this improvement in other-race face recognition occurs during facial encoding or recognition. The current study used the old-new recognition task to examine whether anger reduces the other-race effect by improving face memory for other-race faces in comparison to neutral faces and whether this improvement would be reflected during encoding or retrieval. Caucasian and African American faces were rated as angry or neutral by a separate pool of Caucasian participants. Caucasian and African/African American participants in the old-new task studied the faces rated as most angry or neutral and later identified them among distractors in the test phase. The Dm, FN400, and parietal old-new effect were recorded during the study and test phase for Caucasian participants. Anger did not improve other-race face memory in behavior for either race of participants. For Caucasian participants, activation increased during retrieval of previously studied angry Caucasian faces, which indicates more detailed memory retrieval of same-race as compared to other-race angry faces. This is evidence that experience with same-race faces and not stereotypes of other-race faces influences the other-race effect during memory retrieval.

异族效应是指人们能够更好地识别和记住同一种族的面孔的现象。愤怒的面孔已被证明可以促进促进面孔识别的过程，这反映在研究后记住面孔的比例中。当其他种族的面部表现出负面表情时，其他种族的效应可能会减弱，但没有与事件相关的潜在研究检查过这种改进是否发生在面部编码或识别过程中。当前的研究使用新旧识别任务来检查愤怒是否通过改善其他种族面孔与中性面孔相比的面孔记忆来降低其他种族效应，以及这种改进是否会在编码或检索过程中得到反映。白人和非裔美国人的面孔被一组单独的白人参与者评为愤怒或中立。新旧任务中的白种人和非洲/非洲裔美国人研究了被评为最愤怒或最中性的面孔，然后在测试阶段将它们识别为干扰因素。在白种人参与者的研究和测试阶段记录了 Dm、FN400 和顶叶新旧效应。对于任何一个种族的参与者，愤怒都没有改善其他种族的面部记忆。对于白人参与者，在检索先前研究的愤怒白人面孔期间激活增加，这表明与其他种族愤怒面孔相比，同一种族的记忆检索更详细。
