Detecting and resolving discrepancies: Since the information selected to enter consciousness is usually about changes in the external and internal worlds, when there is a discrepancy between our stored knowledge about the world and an event, it is more likely to come to consciousness. For instance, a woman in a bikini would probably not attract too much attention on the beach, but if she wore the same outfit to a formal dinner it would certainly be noticed. Discrepancies may arise internally as well. For instance, you are usually not conscious of your breathing. However, when you have a cold your breathing may enter your consciousness, and this may tell you to slow down or to see a doctor. Consciousness involves actions to reduce the discrepancy, as when you straighten out a crooked painting on the wall because it does not fit with the other paintings.
