目的：探讨高异族接触经验的汉族大学生在面孔识别中的异族效应及其脑加工机制。方法：选取高接触经验的汉族大学生为研究对象，通过被试内实验设计，采用S1－S2延迟匹配范式，收集NcuroScan公司生产的ESI128导脑电记录系统记录的脑电数据。结果：①在反应时上，面孔一致性的主效应显著（F＝8．34，P＜0．05）；②在N270的平均波幅上，面孔一致性主效应显著（F＝34．77，P＜0．05），面孔一致性与民族交互作用显著（F＝8．23， P＜0．05）；半球分析发现，当面孔为异族面孔时，面孔一致性主效应显著（F＝18．71，P＜0．05），民族与面孔一致性的交互作用显著（F＝9．10，P＜0．05）；③在N400的平均波幅上，面孔一致性主效应显著（F＝7．51，P＜0．05），面孔一致性与民族交互作用显著（F＝5．35，P＝0．05）。结论：①高异族经验大学生在深层加工上依然存在异族效应；②高异族接触经验大学生在早期结构编码上可能采用了更为熟练的局部加工方式；③支持了Bruce和Young的多阶段认知模型，说明面孔识别确实存在早期结构编码和晚期面孔认知两个不同加工阶段。
目的：探討高異族接觸經驗的漢族大學生在麵孔識彆中的異族效應及其腦加工機製。方法：選取高接觸經驗的漢族大學生為研究對象，通過被試內實驗設計，採用S1－S2延遲匹配範式，收集NcuroScan公司生產的ESI128導腦電記錄繫統記錄的腦電數據。結果：①在反應時上，麵孔一緻性的主效應顯著（F＝8．34，P＜0．05）；②在N270的平均波幅上，麵孔一緻性主效應顯著（F＝34．77，P＜0．05），麵孔一緻性與民族交互作用顯著（F＝8．23， P＜0．05）；半毬分析髮現，噹麵孔為異族麵孔時，麵孔一緻性主效應顯著（F＝18．71，P＜0．05），民族與麵孔一緻性的交互作用顯著（F＝9．10，P＜0．05）；③在N400的平均波幅上，麵孔一緻性主效應顯著（F＝7．51，P＜0．05），麵孔一緻性與民族交互作用顯著（F＝5．35，P＝0．05）。結論：①高異族經驗大學生在深層加工上依然存在異族效應；②高異族接觸經驗大學生在早期結構編碼上可能採用瞭更為熟練的跼部加工方式；③支持瞭Bruce和Young的多階段認知模型，說明麵孔識彆確實存在早期結構編碼和晚期麵孔認知兩箇不同加工階段。

Objective:To explore the race effect and the brain processing mechanism in face recogni-tion in Han college students with high other race contact experience.Methods:The participants were col-lege students with high contact experience with other race.Adapting within subjects experimental design, and S1-S2 delay matching paradigm.The EEG data was collected by recording system of ESI128 chan-nel made by NcuroScan corporation.Results:①The reaction time's presented that the main effect of the face consistency was significant(F=8.34,P<0.05).②In the mean of amplitude was N270,the main effect of the face consistency was significant(F=34.77,P<0.05);The analysis about brain hemisphere indicated that when the face was other face,the main effect of the face consistency was significant(F=18.71,P<0.05),the interaction between race and face consistency was obvious(F=9.10,P<0.05).③In the mean of amplitude was N400,the main effect of the face consistency was significant(F=7.51,P<0.05),the interaction between race and face consistency was significant(F=5.35,P=0.05).Con-clusion:①Han college students with high other race contact experience still have other race effect in deep processing;②Han college students with high other race contact experience may adpat the more ma-ture partly processing style in early face structure coding;③The present study surportesd the Bruce and Young'sMulti Stage of Cognitive Model,the findings illustrate that the face recgonition containes two differ-ent processing stage which are early structure coding and late face recgonition.
