I am agnostic to how much things are separate. At any particular time a machine can be doing less or more of each of these things. For example in humans it is quite common to talk of concentration. E.g. "I'm sorry I wasn't concentrating on what you said, could you repeat it." "Stop thinking about the girl, concentrate on the problem at hand."

If more low level elements are devoted (neuron-equivalents?) to a task in general it is giving it more potential memory, processing power and bandwidth. How is that decided? In some connectionist systems, I would associate it with the stability-plasticity problem described here in section 6. http://www.cns.bu.edu/Profiles/Grossberg/Gro1987CogSci.pdf The nutshell is if you have new learning, should it overwrite the old? If so, which information, if not, please can I have your infinite memory system. Assuming you are implementing this on a normal computer you can easily see that it all boils down to these resources. In the brain not all elements can work at peak effectiveness at the same time (consider the perils of driving while on the mobile *). So even if you had devoted the elements, then further decisions need to be made at run time. Different regions of elements become the resources to be rationed. For example Short-term memory becomes a resource you have to decide how to use. Also oxygen would seem to be a resource in short supply, within the brain. The question remains the same, how should a system choose what to do or what to be.
