A fundamental challenge in face recognition lies in determining which facial characteristics are important in the identification of faces, like the eyes and mouth. Surprisingly, however, one rather prominent facial feature has received little attention in this domain: the eyebrows.
Volunteers were asked to identify fifty famous faces, including that of former U.S. president Richard Nixon and actor Winona Ryder. The photos were digitally altered and shown either without eyebrows or without eyes. When celebrities lacked eyes, subjects could recognize them nearly 60 percent of the time. However, when celebrities lacked eyebrows, subjects recognized them only 46 percent of time.
