Abstract:
Two rhesus macaques (Macaca mulatta) with a lifetime of continuous exposure to mirrors showed a dramatic and reliable reinstatement of social behavior directed toward the mirror when it was simply moved to a new location. These data are discussed in the context of repeated failures to find self-recognition in monkeys and several recent claims that a cessation of social behavior directed toward mirrors can be used as evidence for the beginning of self-recognition in nonhuman primates.
