ABSTRACT

The own-group bias (OGB) in face recognition refers to the finding that in-group faces are recognized with greater accuracy than out-group faces. Current literature emphasizes the importance of in-group characteristics for the OGB. Across two experiments we explored the importance of both in-group and out-group characteristics. Using an old/new task, Experiment 1 categorized faces by university membership and found no evidence of the OGB or a relationship between the OGB and attitudes towards the in-group. Experiment 2 used real-world categories of football (soccer) teams, with the out-group representing a high or low threat to the in-group. Here we found an out-group disadvantage (rather than an in-group advantage) only when the out-group was low threat, and a relationship between out-group but not in-group attitudes and the size of the OGB. These findings suggest that the characteristics of the out-group can be more important than the in-group in modulating the OGB.

摘要

人脸识别中的自组偏见（OGB）指的是发现组内人脸比组外人脸的准确性更高的发现。目前的文献强调了OGB组内特征的重要性。在两个实验中，我们探讨了小组内和小组外特征的重要性。实验1使用旧/新任务，按大学会员身份对面孔进行了分类，没有发现OGB的证据或OGB与对小组内态度之间的关系。实验2使用了现实世界中的足球（足球）类别，其中外组代表对组内的威胁程度高或低。在这里，我们仅在小组外威胁较小时才发现小组外劣势（而不是小组内优势），并且发现小组外而非小组内态度与OGB大小之间的关系。
