The perception or attention is dominated by the active task at hand.
Consciousness as a door between physical and mental realm.
Consciousness is a brain’s way of giving notations to different patterns in the world. Now if you ask what is consciousness? You are asking the question why did you give the notation you gave in the first place?
If you ask why did you give the abstract notion of quantity nine the symbol it has now, No one can say anything about that. In a similar way, when you ask of the nature of feelings you have, I would say they don’t have any nature but just notations to tag some pros and cons on different contexts.
