Can a chimpanzee recognize its own reflection in a mirror?
Recognition of one’s own reflection in a mirror qualifies as an objective test of self-awareness. Although most primates appear incapable of learning that their behavior is the source of the behavior depicted in a mirror, the present study replicates previous reports showing that both chimpanzees and orangutans are capable of self-recognition.
