What Are You Doing When You Show a Mirror or Two an Animal?

When a mirror is first put into the enclosure, at least as gallop reported in in the chimpanzies that he was working with, they would at first react as if it was another animal. But these, a social type reactions decreased rapidly over the course of two or three days. And by like, day four or five, they were just not doing this any more. So once they'd been exposed to a mirror for a few days, the chimpanzees would start performing all kinds of exploratory and grooming behaviors with respect to their own bodies which is fascinating.
