摘　　要：本文旨在考察汉族大学生对内外群体成员面孔的再认是否表现出明显的内群体效应。方法:实验以28位在校汉族大学生为被试,以内外群体(汉族和壮族)成员的中性面孔作为刺激材料,使用学习-再认实验范式进行研究。结果:(1)相对于外群体成员面孔的辨认,汉族大学生对内群体成员面孔辨认的正确率、反应时都没有显示出优势,内群体效应不显著;(2)但在识别内外群体成员面孔时,其虚报率显著,汉族大学生再认汉族面孔时虚报率偏高;再认阶段被试对不同图片类型的辨别力d′差异不显著;(3)汉族大学生面孔识别时,受熟悉度以及面孔特征等因素影响,识别内群体成员面孔时诱发的P1、N170潜伏期和峰值以及P2、N250波幅与识别外群体成员面孔时诱发的脑电差异都不显著。结论:随着民族间文化交流的深入,高校学生间交往的密切,熟悉度的增加,面孔识别过程中不一定存在内群体效应。The purpose of this paper is to investigate whether the recognition of the faces of the members of the inner and outer groups by Han college students shows obvious inner group effect.Methods:28 college students of Han nationality were selected as subjects,and the neutral faces of the members of the inner and outer groups(Han and Zhuang)were used as stimulus materials.Results:(1)compared with the recognition of the faces of the members of the outer group,the recognition accuracy and response time of the Han students to the faces of the members of the inner group did not show an advantage,and the effect of the inner group was not significant;(2)however,when recognizing the faces of the members of the inner group and the outer group,the false report rate was significant,and the false report rate of the Han students when recognizing the faces of the Han students was high;at the recognition stage,the subjects had different picture types There was no significant difference in discrimination D′.(3)influenced by familiarity and face characteristics,there was no significant difference in P1,N170 latency and peak value,P2,N250 amplitude in face recognition between Han college students and non group students.Conclusion:with the deepening of cultural exchange among ethnic groups,the close communication between college students and the increase of familiarity,there is not necessarily inner group effect in face recognition.
