Boris,
EP : I think that Rick did not claim that CV is in external environment.
HB : He does not claim now. But go and look in CSGnet archives. I know exactly what Rick is aiming at.
EP : : Instead he claims that it is inside the observer as the observer’s perception of what the controller is controlling (or rather what the controller is doing when she is controlling her perception).
HB : Even this statement is wrong. Observer can’t have inside “perception of CV”. What is that ? Perception is the only “controlled variable” in environment. Perception is CV !!!
You can’t perceive “controlled variable” from outer environment. You can’t perceive that something is controlled outside. Perceptual signal is one-dimensional at least first order.
EP : I agree that this way of thinking can be somewhat narrow and problematic,
HB : You can bet it is…
EP : …but I believe it fits perfectly well to Rick’s way of doing empirical research,
HB : Of course it does as it’s wrong way. His linear thinking is clear RCT.
-
Behavior is control – that’s how difference between cursor and target vary (CV in outer environment)
-
The product is some “Controlled Perceptual Variable” which carry’s control into organism where “CPV” is again controlled in comparator. Why do you think Rick is explaining just outside control. Because he can’t explain what is happening inside organism with his RCT.
How CV is present in perception ?
RCT (Ricks Control Theory) definition of control loop
-
CONTROL : Keeping of some »aspect of outer environment« in reference state, protected (defended) from disturbances.
-
OUTPUT FUNCTION : controlled effects (control of behavior) to outer environment so to keep some »controlled variable« in reference state
-
FEED-BACK FUNCTION : »Control« of some »aspect of outer environment« in reference state.
-
INPUT FUNCTION : produce »Controlled Perceptual Variable« or »Controlled Perception«, the perceptual correlate of »controlled q.i.«
-
COMPARATOR : ???
-
ERROR SIGNAL : ???
This is Ricks Control Theory which he exposed through last 5 or 6 years on CSGnet.
EP : ….when he is trying to prove PCT (as empirical phenomenon) by his studies.
HB : He is traying to prove his RCT. If he wanted to prove PCT he would analyse other behaviors like he did sleeping.
RM (earlier) : Sleeping is a tough one but I think it is controlling done by the autonomic nervous system that has the aim of keeping some intrinsic physiological variables in genetically determined reference states
HB : This about PCT and how control works in PCT. Control is not happening outside but inside.
HB : The main question is : How did CV came into the controllers and observers perception and later into hierarchy ? Was it already there ? Rick’s many years correspondence show that he is transferring control from environment (CV) into organism through “Controlled Perceptual Variable” or CPV. And that Control is being produced with “Control of behavior”. There is no canonical principle in PCT so that something that is controlled in Perceptual hierarchy is “canonically controlled” also in external environment. This was expressed man times from many members :
“To the extend that something is controlled inside is also controlled outside”. Now we know that this is not true, because I offered analysis of other everyday behaviors which show no such thing as “canonical control”.
EP : What I suggested was that there is (or can be) something in the real reality (not necessarily outside the controller, it can be also in her like in the case of hunger or itch), which is perceived when the controller has a perception which she tries to control. And I also suggested that that something could be called RREV or just “object of perception”.
HB :And in Ricks case is "something in the real reality, which is perceived as CV or distance between “cursor and target” ? Is this what you wanted to say ? I also don’t understand what could be “object of perception” ?
EP : This RREV, or whatever you want to call it, is what is affected by the controller’s output if the control is successful.
HB : I’m sorry I don’t understand this either. “RREV” exist in outer environment only if effects of controllers output are successful ?
HB : Well it’s everything to abstract. Could you give some real life example how this works, beside Ricks “chewing” laboratory experiment" which has no use in explaining other behaviors.

Sorry Eetu that I jumped in…
There is no “CV” in external environment as you can’t explain too many behaviors with such an approcah. But you can cause deeper misunderstandng of PCT and you can cause that PCT will has less and less value showing where Bill was contradicting himself. Anyway Rick, I think that you give a dame about PCT. But you are taking care of your ass and nonsesne RCT.

EP: Hmm, just a thought: The control (any control of perception, except temporarily in imagination) is constrained by “Real Reality” (RR). Powers says in the quotation: “When we apply a disturbance, we apply it to CV, not to p.” This applies also to observer: she has a perception p of the CV. When she applies a disturbance (because of TCV), she applies it to CV not to her p.
RM: I think the problem is in thinking of a CV as something to be perceived. In fact, the CV is a perception for both the observer and the controller. It is an actual perception for the observer; the distance between cursor and target, for example, is a perception for me as an observer; it is also a perception in theory for the controller. The theoretical nature of the controller’s perception is indicated by the fact that the CV is represented as the theoretical variable p in the model of the controller.
HB : Observer will perceive whatever is outside in his way and controller in his way. What observer will perceive and control is question for TCV. But I’m sure that most people will not perceive “CV”. And I’m sure you wouldn’t be one of them.
EP: Thus that which is called here CV is outside of both the controller and the observer.
RM: The CV actually exists only as a perception inside the observer (in fact) and in the controller (in theory). The CV certainly can “look like” it is “outside” of the controller and observer, just as the distance between cursor and target appears to be “outside” both. But according to PCT the CV is inside the brains of both the observer and controller.
HB : How would you know that “CV” is inside observer ? In theory ? Or in practice.
EP: Where is it then? I think it is in RR.
RM: According to the PCT model, the CV is a perception (in both the observer and controller) inasmuch as it is a FUNCTION of variables in real reality (RR).
HB : According to PCT “CV” is not a perception. You are lying Rick. There is no “Controlled Variable” in external environment and no “Controlled Perceptual Variable” in observer according to PCT.
![cid:image001.jpg@01D37ABE.36063DF0]()
EP: What the observer infers and claims to be controlled is thus the object of her own perception, something in RR which she assumes (because of the empirical findings) to be also the object of the perception of the controller.
RM: The observer doing the TCV does not have to infer anything about the “object of her own perception” that the controller is controlling.
HB : So observer doing TCV is some expert for TCV ?
RM : The observer doing the TCV simply observes that something she perceives – such as the distance between cursor and target – is being controlled in the sense that it is being protected from disturbance by the actions of the controller.
HB : You are breaking World Record in talking nonsense. And how controller is “protecting distance between cursor and target”. With Telekinesis ? Or with yome “magnetic field” ? Or maybe he is protecting socket that somebody wouldn’t pull out electrical cable and cause the end of “experiment”. I must say that I agree with you.
RM earlier : In my rush to show that this is not the case I came up with what has to be the dumbest rebuttal of all time – outdoing even myself in stupidity;-)
RM : The observer may think of that perception – the CV-- as an objective variable in the outside world; the distance between cursor and target, for example, certainly seems like it is “out there”. But the variable that appears to be “out there” is actually the result of a perceptual computation – a FUNCTION of sensory input – that produces that apparent reality. For example, the distance between cursor and target is the result of a perceptual computation that involves taking the difference between two sensory inputs – one from the cursor and the other from the target.
HB : Sorry Rick PCT is not working in this way. How do you imagine that “two sensory inputs” look like. X and Y axis like in your Toy Helicopter experiment with Schaffer ? Target through left and cursor through right eye ???
RM : So the FUNCTION that results in the appearance of the CV as the distance between cursor and target is a subtraction.
HB : So you perceived subtraction ?
EP: Thus, I think that RREV (or simply just “object of perception”) is a useful and necessary concept because without it one must say something like this: “The controller is controlling the same perception which the observer has”, which literally means that there is one perception which is common to and shared between controller and observer.
RM: I consider that a feature, not a bug. When an observer has successfully tested to determine the variable the controller is controlling, the observer can be said, for all intents and purposes, to be perceiving what the controller is perceiving – the CV.
HB : Did you try this with anybody or you are just imagining and dreaming ?
EP: Yet we know that those two subjects certainly have both their own perceptions – they have their own perceptual signals and those signals are not necessary similar.
RM: If the perceptual signal that corresponds to the variable controlled by the controller is not the same as the perceptual signal that corresponds to the variable that the observer thinks is being controlled, the observer will realize this immediately (because the controller will not be systematically resisting disturbances applied to this variable). In this case, the observer will change her hypothesis about the variable that is actually being controlled. The observer will continue to change hypotheses about the CV until she hits on one that is protected from all disturbances.
HB : Are there also bullit disturbances ? Describe to us hypothesis about CV being “protected” from all disturbances ??? Which are all these disturbances that you should protect “distance” from ? He,he. What an imagination ?
RM : In that case, she has discovered a variable the controller is controlling – the CV – and, for all intents and purposes, is, perceiving what the controller is perceiving.
HB : So controlled and observer are perceiving the same “CV” ?
EP: If the bat perceives a fly using its ultra sounds and sensible ears it must be very different perception compared the visual perception of the bat researcher who sees those ultrasounds from a measuring device (or the fly visually). What is common to the perceptions of the bat and the researcher is not the perceptions as such but the object of these perceptions, some RREV, even though this RREV is described in the research report by using the perceptions of the researcher (and her assumptions of the possible perceptions of the readers).
RM: The observer doesn’t have to experience the CV in the same way as the controller does in order to successfully determine what perception the controller is controlling.
HB : So now you are saying that observer and controller do not perceive CV in the same way ?
RM : This can be illustrated with the compensatory tracking task. The observer of the behavior in this task doesn’t need to actually see the difference between cursor and target on the screen as the controller does that task.
HB : So observer has covered eyes with yomething so that he doesn’t perceive the same “CV” as controller ??? He,he. What an imagination.
RM : The observer can tell from a plot of the difference between the position of the cursor are target varying over time (along with a plot of the disturbance and the controller’s output) that the perception (cursor - target) is the CV.
HB : Controller must be a good “teacher” to explain to observer what she/he is perceiving ?
