The "mirror self-recognition task" used in cog dev involves placing children in front of a mirror with a red dot on their forehead. Up until a certain age the baby treats the image as if it's another child and tries to interact and play with it. However, the older babies will realize that they are looking at themselves and will reach up to pull the sticker off their forehead.
They have done the same thing with chimpanzees and elephants and it's really cool to watch the videos. You see the chimpanzee try to attack its reflection at first, but then it slowly figures it out and starts grooming its hair and checking out its teeth and stuff. (And then peeling the sticker off its forehead.)
I've seen some of those videos before. I believe the chimp was called betty, but nevertheless, they gave it/her make up and it started drawing on itself using the mirror as a guide. Another clip showed it immitating one of the handlers putting make up on and it started using lipstick on its lip, instead of its face.
