Having experimented quite a bit with float tanks, the brain certainly seems to have a need to continue to process information, whether of an external or internal nature. John Lilly recommend the tank experience for that reason - it allowed the user to process internal information that they would otherwise not be able to do amongst environmental distractions. In my experience, solutions to several problems I was working on in frustration, revealed themselves while I was in the tank.

I have to disagree here. I don't think an infant needs to process input in a *rational* format in order to be aware of it - think of all the irrational people out there! :-). All healthy infants respond to environmental stimuli immediately after birth. I would call that response awareness. Proving they are self-aware however, may prove as difficult as doing it for anyone else.
