RM: What I am hoping for is a verbal description (or,better, a diagram) of a PCT model of two people lifting a couch. You don’t even have to model moving the couch; let’s just see what’s involved in cooperatively lifting it.
HB :
Maybe until Kent will find time to »work on it«, you could read his article : The collective control of perceptions:
constructing order from conflict (2004)

Yes, I’d be interested in seeing that model, too. Unfortunately, I don’t have time to work on it myself at the moment.

RM: Great to hear from you Mike!
MM: I’m sure this is adding complexity when you seem to be looking for simplicity, but my way of controlling my own perception of getting my friend’s couch moved might be to kick in twenty bucks to hire some movers.
RM: It’s not so much adding complexity as going outside the constraints of the problem. Here’s a restatement of the problem:
It takes two people to lift a couch so you and the friend have to do it together – you have to cooperate in order to produce the desired result: the couch lifted and moved from here to there. So how is this cooperative result achieved, according to PCT?
RM: What I am hoping for is a verbal description (or,better, a diagram) of a PCT model of two people lifting a couch. You don’t even have to model moving the couch; let’s just see what’s involved in cooperatively lifting it.
MM: Can two people (control systems) really share a perception in the way you have described?
RM: I think this is a very good point. Two people are looking at the situation from different locations so right there their low level perceptions have to be different. But their perception at a higher level could definitely be the same. For example, if the couch is to be moved “next to the lamp” then both of the friends can perceive the same relationship (couch beside lamp) even if the components of that perception (the lamp and couch) look different from each of their perspectives.

FN: First, the from here to there bit. It’s always been the case that the two of us knew where the couch was going. Whether our references were exactly the same or not I think they were close enough for government work…
FN: In short, I think we were able to cooperate because (a) we had very similar understandings of what was or would be involved and (2) we were willing to undertake the task.
FN: Don’t know if this is what you were looking for or not.
RM: Not quite. I want to see how you would actually model the situation using a PCT model. And I would like you to do it for what seems to me the simplest possible case of cooperation: where two systems are needed to produce a result that both want: a lifted couch. That is, describe how two control systems that both want a couch lifted would get this to happen.
Martin Taylor (2014.12.06.10.22)–
MT: As Fred said, there are two separate issues here.
MT: Firstly each of them must perceive that the other controls a perception of where the couch is to go and that the reference values for their perceptions corresponds to much the same place in the environment. There are protocols for getting to this state [Martin Taylor 2014.11.26.16.45].
RM: Again, let’s simplify this by assuming that both people know what perception is to be produced – a lifted couch – and that both are willing to contribute to producing this result.
MT: Secondly, the interesting question is how they coordinate their lifting and moving actions at the lower levels to reduce the error in the “couch-location” relationship perceptions.
RM: Yes, that’s what I want to see a model of!
MT: Didn’t Tom Bourbon do some modelling of this situation with four people carrying a table, or some such, a long time ago? Do you know if the results are anywhere accessible? Or is my memory at fault?
RM: I think you are right. I think he reported it at a meeting, though. I don’t think it’s described in any of Tom’s published papers. However, Tom’s work on two-person interaction is definitely relevant to the question of how people cooperate. I think the answer to my question could certainly be gleaned from Tom’s models of two-person interaction. And from Kent’s as well. Indeed, what I’m looking for is a model along the lines of those developed by Tom and Kent.
