- Nice post Martin. I think you honed in on a common misconception about
- PCT. If I didn't already understand your point I know that your nice
- discussion would have helped me towards that understanding.

-
- Well, I'd be inclined to say that control theory does place the locus
- of control squarely inside the control system (not in the environment).
- Variables in the environment are controlled (maintained in reference states
- against disturbance) and this occurs because of the nature of the control
- system itself (closed loop, negative feedback and, especially, HIGH GAIN);
- not because of the nature of the environment. So whoever said that the locus
- of control was inside the organism (like the cognitivists, maybe) was right;
- PCT just shows why this is the case and what it imples about the nature of
- behavior (it is controlled perceptual experience; I like to say it means
- that behavior is a subjective, not an objective phenomenon -- the cognitivists
- never got THAT part).

-
- Nice distinction. Yes, PCT is interested in behavior-2, and sees behavior-1
- as just a side-effect of behavior-2, interesting to an observer, perhaps,
- but usually irrelevant to the behaving system.
-

-
- Correct. And the main reason is because the disturbances (which are
- continuously influencing all 5 "behavior-1" behaviors are invisible.
- So it is truly impossible to tell (just by looking at the behavior of
- all 5 objects -- or, I might add, by doing any kind of analysis of their
- behavior-1 behavior) which is being moved intentionally. In fact, the idea
- that ANY one is moving intentinoally would not even occur to most observers;
- all the objects just move around in an arbitrary pattern. The fact that
- one of the visible behavior-1's is the result, in part, of a person's
- active efforts to resist a disturbance is completely invisible -- because
- you can't see the disturbances. The situation is similar to the one we are
- in when we just watch people behave; all that behavior looks like behavior-1
- because the disturbances are invisible so the resistance to disturbance
- is invisible. Control theory suggests that some of the events we see as
- behavior-1 may be the result of behavior-2 -- ie. control. We can tell
- which behavior-1's are the result of behavior-2 by disturbing a behavior-1
- variable and looking for lack of (or considerably reduced) effect. The
- mind reading program does this because it can "see" the disturbances that
- the observer of the behavior of the objects cannot see; so the program
- can determine which disturbance is being systematically opposed.
