Do you recognize yourself in a mirror? Does your dog? Scientists have determined that most children recognized themselves in a mirror by the age of 2, but what about animals?
In 1970, a scientist named Gordon Gallup Jr. created the Mirror Test or MSR Test to see if animals had self-awareness. It works like this: a mark is painted on an animal in a place they cannot see, like their face, and then they are placed in front of a mirror. If the animal recognizes the mark as being something that shouldn’t be there and attempts to remove it, then they have self-awareness.
