Have there been any psychological studies on how quickly a person can change
from one type of biofeedback response to another? I've only seen 
demonstrations of biofeedback on PBS and the like. Usually the person has some
device attached to them to monitor skin resistance or blood pressure or 
something similar. The person watches some kind of measurement of these 
responses on a guage or computer screen. But for the most part, these 
responses seem to change rather slowly. If switching between the proposed 
8 different responses has a significant transition time, then realtime
control would be slow. EKGs may change rapidly, but a users controlled-change
may be sluggish in stablizing.  I'd be interested in your results with this
project.
