Divided thought

We are all able to walk or drive while independently conversing or thinking or planning. Similar parallel processing occurs in Asa H. Input devices and output servos may or may not be shared by the two (or more) processing streams. In Asa, each stream may take the form of an independent concept hierarchy. Whether these hierarchies can evolve to the point of forming independent divided consciousness (Ernest Hilgard, Divided Consciousness, Wiley, 1977) or multiple personalities remains to be seen.
