The chimps' behavior in front of the mirror would suggest that apes have a sense of self.  But, to create this skill is important to expose the chimpanzee to training.

When the ability to identify oneself in the mirror appears is frequently regarded as self-awareness. Most of the time, children under the age of 2 and most animals do not have this capacity until extensive training occurs. To expose chimps to a mirror allow them to interact with it in a more self-directed way, thus, the sense of self-awareness will be foster to create certain behavior. For example, the use of the mirror to aid in grooming and to divert themselves suggest that chimpanzees had built a sense of self.
