Objective test for self-awareness? Are there any means by which an observed entity (e.g.: an AI) can be tested for self-awareness using/applying/affecting mainly its visual-oral-auditory-senses and observed responses of same? Failing that, are there any such tests for organic life-forms?
To test self-awareness in animals there is the Mirror test. It involves painting something on the animal's head/face without their knowledge and observing what they do when they notice the paint in their own reflection in a mirror.

Additionally, robots have been tested for simple self-awareness by researchers at Rensselaer Polytechnic Institute.
