We get disgusted by things because our parents, siblings and friends react in a disgusted manner when we do something disgusting. (Unless the individual finds they really don't like the taste/look/smell of whatever disgusting thing it is.)
It's the same with the mirror test, I doubt there's ANY human alive who wasn't with their parent or someone when they were confronted by mirrors when they were young, who said "who's that? That's YOU!" over and over again until they were too old to talk like a ninny to.
