Barb,
I thought that you will be more acceptable for your Dads’ ideas but it seems to me, that you are more supporting Ricks’ RCT then your Dads’ PCT.
I’ll try a little more this time. On the end there is my proposal about what I think PCT is. It’s some sort of summary of your Dads’ legacy. I think it’s right that somebody make such a overview over his theory every year so to honor his memory. Â
It takes time to go through Bills’ enormous literature. I would suggest again if You could do it and provide PCT with inserts from his work if it’s true what you told me that Your Dad and Mom are the only that are important to you.Â
But after you emotional »explossion« I really donIt know on which side you are : Dad and Mom’s or Ricks ???
And for that reason it seems useless to prove to Rick that he is wrong. Rick is promoting his RCT and »Behavior is control« and he never showed one single evidence that he is telling the truth. And you beleive him not your Dads’ legacy ???Â
They have totatly diferent concept of understanding how organisms function. .
I was shocked and appeled that Rick used particular situation to promote his RCT and »Behavior as control«. After all these years of conversations he didn’t show a single evidence that he could be right about that »Behavior is Control«. But he did admitt many times that output in PCT is not controlled. Output can be equated with behavior. At least as muscle tension is concerned.
Beside these contradiction in which he once claim that »Output is not controlled« and once that it is, there are also other contradictions. Everything can be checked in CSGnet archives.
And you are shocked because I »attacked« Rick for being ignorant about PCT and because he was promoting »Behavior is control« and his RCT instead of »Control of perception« and PCT ? Unbeleivable.
I think that you should be satisfyed that somebody is revealing PCT through your Dads’ literature and not just through imagination as Rick is doing.
I’m taking you also responsable for what Rick is doing for a long time, although I provided all evidences that his RCT theory with wrong elements in control loop is total opposite to Bills’Â PCT. For now Rick didn’t deny it.
What I was aming at was to honor PCT and memory to Bill and simultaneously showing that Rick should do the same. Ricks’ RCT is just phylosophy. Will you provide necesary evidences ?
And beside that you invited me to show from time to time on CSGnet. Would you like that Rick writes whatever he wants or you want some synhronization with PCT on CSGnet. Rick is for a long time quite far from it.
I think that you should criticize Rick for what he did. I used Bill sources and honored his PCT. Is this what I should be shame of ?
What’s wrong with my argumentative way ? That I’m using your fathers’ literature to prove what PCT is ? Is this wrong argumentative way ??? Is wrong argumantative way proving that Rick is not right ? That your friend Rick is being target for his ignorancy ? Should we let him talk whatever he wants wtih no concern to PCT ? What »argumentative way« is right for you ?
O.K. let us make an agreement. As soon as anybody of you provide evidences that »Behavior is control« and that it can produce »Controlled Perceptual Variable« or PCV, I’ll appologise to you, Rick and to all those who were hurtby my statements and citations of Bills’ literature. But if you don’t provide evidences that »Behavior can be control« I hope that you’ll apologize to me. Is this fair ?
By ma oppinion CSGnet forum should be some scientific forum not only friendship discussion forum. So evidences has to be put »on the table«, like in every scientific discussion. You agreed once with this. Don’t make differences between members. If something is valid for one member it should be valid for all members.
As I saw from other discussions I could conclude that PCT is still not enough established on CSGnet forum, and Ricks’ RCT is blooming, I decided to honor Bills’ memory and also give a systematic answer to Kaufmans’ »10 big ideas« about PCT
I thought at first that somebody more close to Bill could do it, but till now I didn’t see any such contribution. As I said before I’ll try a little more, but more probable is that I’ll have enough of everything and I’ll let you to your Destiniy you choosed. If you want CSGnet forum to be dedicated to Rick and his RCT then what can I do more then I did ?
So I decided to make probbaly for the last time a brief abstract from Bills’ lietrature in 10 or maybe more points to compare them to Kaufmans’ points. But in the future I think it would be more suitable if you Barb or any member of your “core” group do it to honor the memory on your father and PCT.
Here is my interpretation of highlights from Bills’ literature which tends to give a short »abstract« of his enourmous work. The aim is also to show how it looks like when CSGnet forum is dedicated to his work so that we see really his words, not Ricks’ RCT. Ricks’ work (RCT) is in most cases what we see here. So I’m asking myself to whom CSGnet forum is dedicated ? To Bill or Rick ???
Anybody who wants to express oppinion about work of William T. Powers is welcome. In this way we could maybe establish what PCT is and come to some normal PCT agreements, not RCT agreement. So please no contributions in the form of NON-PCT theories like Rick is.Â
I must also emphasize that my »abstract« of »10 PCT Thesis« usees mostly Bills’ text :
-
To control perception means to act on it in such a way as to bring it to desired state and keep it there despite other forces tending to disturb it.
-
Because other forces and influences are always acting, there is no way to predict exactly what action will be needed to control perception.
-
In order to control is absolutely necesary to perceive. We control perception of our and other behavior not control it directly. Our senses and further neural equipment that builds abstract perceptions out of simple ones, provide us with a world to experience and it is only that experienced world that we can control.
-
Human beings and other animals produce behavior for one reason : to control their experiences of the world.
-
Behavior affects the world that really exist. Those effects, after being filtered through the properties of human perception, show up as changes in the world we know about.
-
"Controlling perception" means controlling the state of some specific perception, not changing one perception into a different perception. When we control a perception of the distance of the glass of water from our mouth, we are controlling the perception of distance, not changing the perception of distance into a perception of nearness.
-
We can go a long way toward figuring out what another person is controlling if we are willing to do some careful observing and some experimenting. If we apply disturbances to something someone is controlling, we can, if we guessed right, expect to see or feel the other person "pushing" back, keeping the disturbance from affecting the perception they control. The point of control is to be able to counÂteract *unpredictable* influences and happenings that interfere with control.
-
Every Living Control System must have certain major features**.** The system must be organized for negative (not positive) feedback, and it must be dynamically stable – it must not itself create errors that keep it hunting about the final steady state conditions. The Living Control System of this kind must sense the controlled quantity in each dimenssion **in which the quantity is to be controlled**; this implies the inner model of the quantity in the form of a signal or set of signals. It must contain or be given something equivalent to a reference signal (or multiple reference signals) which specifies the »desired« state of the controlled quantity **that is to be controlled**. The sensor signal and the reference signal must be compared, and the resulting error signal must actuate the system's output effectors or outputs. And finally, the system's output must be able to affect the controlled quantity in **each dimension that is to be controlled**. This makes the action the clearest. The system, above the dashed line, is organized normally so as to maintain the sesnor signal at all times nearly equal to the reference signal even a changing reference signal. This is how control is achieved and maintained. The sensor signal and input quantity become primarilly a function of the reference signal originated inside the system.
-
**Control loop functions and how they work :**
CONTROL : Achievement and maintenance of a preselected state in the controlling system, through actions on the environment that also cancel the effects of disturbances.
OUTPUT FUNCTION : The portion of a system that converts the magnitude or state of a signal inside the system into a corresponding set of effects on the immediate environment of the system…
FEED-BACK FUNCTION : The box represents the set of physical laws, properties, arrangements, linkages, by which the action of this system feeds-back to affect its own input, the controlled variable. That’s what feed-back means : it’s an effect of a system’s output on it’s own input.
INPUT FUNCTION : The portion of a system that receives signals or stimuli from outside the system, and generates a perceptual signal that is some function of the received signals or stimuli.
COMPARATOR : The portion of control system that computes the magnitude and direction of mismatch between perceptual and reference signal.
PCT interpretantion of control loop should be in form of perceptual control not control of behavior.
Bill empahsiszed importance of perception for control clearly :Â
»Our only view of the real world is our view of the neural signals that represent it inside our own brains. When we act to make a perception change to our more desireble state – when we make the perception of the glass change from »oon the table« to »near the mouth« - we have no direct knowledge of what we are doing to the reality that is the origin of our neural signal; we know only the final result, how the result looks, feels, smells, sounds, tastes, and so forth…It means that we produce actions that allter the world of perception«…
Bill P : Briefly, then: what I call the hierarchy of perceptions is the model. When you open your eyes and look around, what you see – and feel, smell, hear, and taste – is the model. In fact we never experience anything but the model. The model is composed of perceptions of all kinds from intensities on up.
- HPCT: hierarchical PCT are control systems which act not by producing effects on the outside world directly, but by telling other control systems to produce effects at a more detailed level. It is up to those control systems to act in such a way as to produce the detailed effects they are asked about for, thus affecting the higher system’s perceptions in the way it wants. Many levels, obviously, could be arranged in this way. Higher systems use existing control systems at the spinal level. This can be done by adjusting their reference levels which define the state they want their perceptions to be in. We experience hierachical organization quite directly. Consider the following question-and-answer session:
Q: Why did you move your hand?
···
A: To pick up this knife.
Q: Why did you pick up that knife?
A: In order to cut my steak.
Q: Why cut your steak?
A: In order to fit a piece into my mouth.
Q: Why put a piece of it into your mouth?
A: Because it’s not polite to stuff the whole thing in.
Q: Why be polite?
A: So I’ll be asked to dinner again some time.
Q: Why get asked to dinner again?
A: Because I want to save money, and food is exÂpensive.
Q: Why save money?
Etc.
So, as far as we followed, this person moved his or her hand as a means of saving money. Of course the same actions, at each level, also served many other goals we didn’t ask about, among them being the goal of not being hungry. But clearly, each goal was only a subgoal, a perception to be controlled not just for its own sake, but as part of a larger hierarchical control process. There are other paths through this complex hierarchy: why not be hungry? Because it distracts me from trying to write my novel. Why write your novel? And so on.
It must be evident immediately that the brain is not just a simple control system. It’s a huge hierarÂchy of control systems, with many levels and many systems at each level, all these systems operating at the same time. In principle, we could apply small well-calibrated disturbances to different aspects of a person’s environment and body, and set up tens of thousands of equations with tens of thousands of unÂknowns, and use a supercomputer to figure out just which variables at each level were being controlled in which states at a given moment. It’s impossible to do it today.
The system is so huge and complicated that people who own such systems often find that the machinery isn’t working right and they don’t know how to fix it. There are natural mechanisms for resolving problems like internal conÂflicts, but they work slowly and don’t always work, so people have what we call “psychologicalâ€? problems even in perfectly healthy brains and bodies.
The brain goes on working as it always works, perceptions vary, control systems control, and so on, What changes is only our conÂscious acquaintance with these activities, as if we were shining a small flashlight around in a huge room full of running machinery.
All those control systems are always working, which means they are controlling, which means that the perceptions of the things being controlled are still present even if not conscious. The neural signals are present, even if they aren’t reaching consciousness.
This adds up to the second main phenomenon: we experience consciously only a small part of the totality of brain activity going on at any moment, although (the first phenomenon ) it is a changeable part.
If you happen to be conscious of some control process in the middle of the hierarchy, neither at the lowest level nor at the highest, you will be aware of things happening at some modest level of abstracÂtion, and of your own actions, and of what you want to be happening. How you’re doing these things is not normally conscious—that is, you may be talkkÂing, but you won’t be conscious of forming each phoneme or of how your lips and tongue move. And why you’re doing those things is also not generally conscious. At the moment that you’re explaining to the police officer why your attention was distracted from the red light you just drove through, you’re only partly conscious of the background thought of being late to work that made you decide to ignore the red light.
Specifically, we are often in a state where we are aware of a main, foreground, process, but at the same time we are somewhat, marginally, fleetingly, aware of a background process that seems to be about the foreground process. When ideas are presented so abstractly we become conscious of things we had probably been perceiving all along, but hadn’t paid proper attention to. But for some reason, a moment came when the background activities leaked into the foreground and we became aware of them, and even made a comment about them.
The Method of Levels works as non-aggressive, non-coercive, non-bullying way of helping another perÂson to unravel some of the complexities of his own hierarchical structure of control processes—if he or she has asked for help. The iddea is to recognize that a background thought about the subject has just been expressed, and to indicate it, gently, in case the other person might find it significant. The agreement with the other person is that when such an indication is made, the person will at least pause for a moment and explore the background thought, idea, attitude, or whatever it is long enough to see if it’s of any imÂportance. We can refer to the “other personâ€? as the “explorer,â€? the only one who can look to see what is actually going on in that brain.
The point of therapy is not to show how clever, insightful, empathetic, or understanding the guide is. The MOL is a minimalist therapy, doing only what is needed to help a person recognize a problem and find a point of view from which something can be done about it. The MOL is for people who are lost in the complexity of their own lives, who are in conflict, who are out of touch with their own motivations.
Of the highest importance seems to be the idea that people govern their own lives rather than just responding to environmental stimuli or “control their behavior” and behavior of others. People control perception in order to achieve match of actual perception with references in the hierarchy. And people are more or less succesfull at doing it. Helping them to be more succesfull (not to try control them to be “slaves” of our goals) is probably the right way.
This concept encourages us to show respect for others, recognizing that they have their own aspirations and goals and generally find their own ways of getting what they need or want, just as we do. Another important common idea that arises from the first one is that it is not helpful to try to control other people; the result of too ham-handed an approach is more likely to be opposition and downright conflict than benefit. It’s important that people tend to give others room, to put critiques in the form of questions rather than criticisms, and to rely on the client more than the therapist to come up with specific answers to problems.
In HPCT, there are levels of organization, and levels of goals, and there is some highest level of goals that is known as system concepts. But there is no reason to propose that every person ends up organized in exactly the same way at the highest level; in fact, when we consider how and why learning hapÂpens, it’s highly unlikely that people will all have just one small set of most-important goals. If we want to take even a semi-scientific approach to exploring human nature, we must be more open-minded, and wait for the evidence about actual high-level control processes to come in before we even think of trying to pick out universal characteristics. What’s really universal about human beings is that they are unique control systems. What they happen to have learned to control for is far from universal.
Best,
Boris

Boris, I am shocked and appalled that you would use this particular thread as a platform for your ugly language and your argumentative ways. For shame.

[From Rick Marken (2017.05.24. 1250)]
Lloyd Klinedinst (2017.05.24 14:14 CDT)–
from the official PCT website:
William T. Powers, the engineer/psychologist who developed Perceptual Control Theory (PCT) passed away on May 24, 2013 at the age of 86. He will be laid to rest next to his wife, Mary, in a cemetery overlooking the city of Durango, CO. His work will continue, pursued by those who came to know Powers and PCT. His theory will someday receive the recognition it deserves, and so will he.
RM: Thanks for pointing out that today is the anniversary of Bill’s passing. Indeed, it’s the fourth anniversary. I am sure that Bill’s insights (first and foremost being that behavior is control)
HB : I’m wondering Rick, when you’ll stop bullshitting with »Behavior is control« without any evidence. Your RCT control loop with central point that »Behavior is controlled« which produces some »Controlled Perceptual Variable« has nothing to do with Bills’ theory and diagrams (LCS III) where it’s obvious that »Perception is controlled«.
And to make a statement on his day of death that central point of PCT is »Behavior is control« instead of »Perception is controlled« is as I’m concerned a crime.
Let us remember how beauty of PCT function in real words and diagram :
Bill P :
Our only view of the real world is our view of the neural signals that represent it inside our own brains. When we act to make a perception change to our more desireble state – when we make the perception of the glass change from »on the table« to »near the mouth« - we have no direct knowledge of what we are doing to the reality that is the origin of our neural signal; we know only the final result, how the result looks, feels, smells, sounds, tastes, and so forth…It means that we prodduce actions that alter the world of perception…
![cid:image003.jpg@01D23694.7341FD90]()
HB : Did you citate any of his statements to honor memaory of great inventor ?
Do you see any difference Rick between you rude and rough »control of behavior« with »perceptual control« poetry ? I think it’s right that we remember that Bill was a founder of a new original theory which fundaments are »Control of Perception«.
Who are you Rick and why should anyone beleive you ? Except that all maybe is about friendship. And you play on friends feelings. Others tolerate and listen to you because you are friends. And this should be some kind of science ?
I understand that you have no evidences for your statements as many others except maybe »common sense« as Fred. I like Freds’ honest understanding that he doesn’t need PCT to understand with »common sence« that »behavior is control«. It’s probably the same for Carver and Scheier, Vancouver and you. So you could admitt it too. Then we would know that you don’t understand PCT and you don’t need it to understand how and why people behave.
RM ….and theory (thaat, therefore, behavior can only be explained as the control of perceptual input) will someday receive the recognition they deserve; I just wish it would be someday sooner rather than later.
HB : Behavior is not control so it can’t control input, it can’ control anything outside. I’ll citate again great master of »perception«.
Bill P (B:CP):
CONTROL : Achievement and maintenance of a preselected state in the controlling system, through actions on the environment that also cancel the effects of disturbances.
HB : Behavior is consequence of control and it is means by which people control perception inside organism or in the controlling system. Behavior is just support for inside control. It’s not main mechanism of control ouside the system. It’s about control in the controlling system. So I hope that people will recognize soon enough that RCT is not PCT. You’ve misleaded many great people here.
I’m sure that PCT will be once leading theory when younger generation will accept the fact of »Perceptual control« and not »Behavior is control«. It’s about how organisms control inside not outside.
Best,
Boris
