Patrolling the Borders: Experience with Multiple Out-Group Members is Associated with the Own-Ethnicity Effect

Abstract

AbstractThe 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.
