The own-ethnicity effect (OEE) is a recognition deficit for faces of other ethnic groups compared to one’s own group. Thirty-two border patrol (i.e., police) officers at a major international airport expected to have high frequency contact with multiple other ethnic group faces were compared with 32 bank employees and 64 students. German participants viewed out-group faces of African Americans, Mexican Americans/Mexican Nationals, and Turkish faces and German (in-group) faces in a standard recognition and a delayed-matching task. Generally, performance was better as a function of self-reported daily job contact for both tasks. Patrol officers were better with Black faces, while students were better with German faces for the standard recognition task. Although an OEE was present for all groups, it was attenuated for border patrol officers. Job contact with multiple out-groups was associated with face processing. Errors in recognition and matching faces of other ethnic groups pose problems for security in an increasingly global society. Customs agencies and security organizations employing an ethnically diverse workforce along with perceptual training for recognizing and matching out-group members will be better prepared to meet the demands of international security.

自身种族效应 (OEE) 是与自己的族群相比，对其他族群的面孔的识别缺陷。将在一个主要国际机场的 32 名边境巡逻人员（即警察）与 32 名银行员工和 64 名学生进行了比较，这些人员预计将与其他多个种族群体的面孔频繁接触。德国参与者在标准识别和延迟匹配任务中查看了非裔美国人、墨西哥裔美国人/墨西哥国民、土耳其人的脸和德国人（组内）的脸。一般来说，作为两项任务的自我报告的日常工作联系的函数，绩效会更好。在标准识别任务中，巡逻人员更擅长处理黑人面孔，而学生更擅长处理德国面孔。尽管所有团体都有 OEE，但边境巡逻人员的情况有所减弱。与多个外群体的工作接触与面部处理有关。在日益全球化的社会中，识别和匹配其他族群面孔的错误给安全带来了问题。海关机构和安全组织雇用种族多元化的劳动力以及识别和匹配外群体成员的感知培训，将更好地满足国际安全的需求。
