I think one reason is that the PCT has, as yet, no successful
models of cooperation or socialization.
PCT doesn't build special models to account for certain kinds of
behavior; there is no special PCT model of cooperation, socialization
or posting silly comments to the net. PCT is a model of nervous
system organization that can produce _all_ the things we see
people doing. It is a successful model because, so far, it has
never been rejected by experimental test. And it _has_ been
successfully used to explain many different kinds of behaviors,
including "cooperation" (Bourbon et al), "socialization" (Plooij and
Plooij) and the posting of silly comments to the net (Marken et al).
"Model" is ambiguous. You're saying "model" meaning the theory as a model
of behavior, PCT vs. S-R; Bruce Gregory is saying "model" meaning a model
of specific behavior such as ball-catching, arm movement, or balancing an
inverted pyramid, to pick three particularly nice examples that I know about.
What are you doing, Rick?
Is it accomplishing what you want?
.....................................
To illustrate the ambiguity, here are a few quotes from fairly recent posts:
Bill Powers (980622.0928 MDT)--
the case of interest in PCT involves a model of the following form:
Richard Kennaway (980623.1151 BST)--
Wolfgang Zocher presented a model of eyeball tracking, with a comparison to
the observed behaviour of real eyeballs.
Rick Marken (980623.1310)--
See [Bill Powers (980623.1111 MDT)]
for a better explanation (than mine) of the control model of Al.
[Cousin Al, the guy who was nutso about triple axels.]
Rick Marken (980624.0730)--
According to Bill and me, coercion is control of behavior; therefore
it has gain and intention; fear of punishment and the universal
error curve have nothing to do with our model of a coercer (these
may have to be part of a model of the coercee). I'm trying to
understand your (and Bruce's) model of coercion, which seems
impossible; however Bill and I understand it, we seem to be wrong.
Our model, on the other hand, is rather straightforward; if you
understand the basic PCT model then you understand our model of
coercion
[You used both senses of "model" in the same sentence (the last).]
Bill Powers (980624.1001 MDT)--
The model of the two
control systems controlling as they do is already a model of coercion;
there is no separate model of coercion needed.
Bill Powers (980624.1142 MDT)--
This post concerns the program for an inverted pendulum control system....
First I'll describe the strategy of the model and how to run it
[...]
An overview of the model
In this program it is assumed that the control systems can sense

Rick Marken (980624.2200) --
Bill and I tend to agree because we both
understand (from working with models and using these models to
mimic behavior) how the PCT model works and how it applies to
behavior.
[Both senses in the same stentece again.]
Rick Marken (980625.0830)--
I am attaching a little Excel model of a coercer and coercee
interacting.
Bill Powers (980625.1536 MDT)--
Blah, blah, blah. Show me the model.
Bill Powers (980625.1549 MDT)--
Oh, heck. I finally started trying to run the spreadsheet model and
discovered that I have Excel 4.0 and can't read Rick's program.
And so on and on.
