Whether the own-group (own-ethnicity, own-gender, and own-age) biases in face recognition are based on the same mechanism and whether their effects are additive or not are as yet unanswered questions. Employing a standard old/new recognition paradigm, we investigated the combined crossover effects of the own-ethnicity, own-gender, and own-age biases in a group of 160 participants. Result showed that while face recognition accuracy decreased as the number of out-group features increased, the own-ethnicity bias appeared to have more of a unique influence on face recognition than the other biases. Furthermore, we established that in a single group of participants, these biases appear to be based on different mechanisms: the own-ethnicity bias is based on individuation whereas the own-age and own-gender biases are based on motivation.
人脸识别中的内群体（同种族、同性别和同年龄）偏差是否基于相同的机制，以及它们的影响是否具有累加性，这些问题至今仍未得到解答。我们采用标准的旧/新识别范式，对160名参与者进行研究，以探究同种族、同性别和同年龄偏差的联合交叉效应。结果表明，随着外群体特征数量的增加，人脸识别准确率下降，而同种族偏差对人脸识别的独特影响似乎比其他偏差更大。此外，我们还确定，在单一参与者群体中，这些偏差似乎基于不同的机制：同种族偏差基于个体化，而同年龄和同性别偏差基于动机。
