Do we all look alike to computers?

People are better able to recognize faces of their own race than those of other races. One explanation is that this 'other-race effect' is caused by lifelong experience in which faces from some races are more common than other races. A recent article by Furl et al. tests experience-based accounts of the other-race effect by giving computer algorithms of face recognition training on preponderantly Caucasian faces. The only algorithms that reliably produced other-race effects were those that created face representations distorted to emphasize features that individuated faces.
