This article states that as a result of an internal representation of their bodies and parts, macaques “gradually come to mentally regard their hands and arms, and then their entire bodies, from a third-person perspective.” Isn’t that a good definition of self-awareness, one of the supposed differences between humans and other animals and between humans and machines? Have the authors of the study not just shown a major advance in our understanding of intelligence?
