As a relative newbie to the depths of PCT theory and one interested more in the therapeutic MOL side of things, I’m wondering if you can help clarify something for me from your comments below.
You said “being a vegetarian” was a highest level control process and that a lower level would be “it’s wrong to eat animals.” In working with and reading Tim C’s writings, he talks about asking “how” and “why” questions to help move someone’s attention up and down levels. Why questions typically move levels up and how levels down.
So, if I could as “why do you want to be a vegetarian?” And there’s an answer for that… Wouldn’t that imply there’s another level above “be a vegetarian.”?

So I suggest that when you present this diagram you make it clear that this hierarchical model is a hypothesis that has not been thoroughly tested, though there is quite a bit of evidence that the controlling done by humans is a hierarchical process.
RM: But for your audience, Fred, I think the hypothetical hierarchy can be most useful to show that, in principle, complex behaviors, like being a vegetarian, can be seen as a hierarchical control process. The highest level perceptions we control are system concept type perceptions, like “being a vegetarian”. These highest level perceptions are controlled by setting references for the appropriate lower level perceptions, such as principles (“it’s wrong to eat animals”), which are controlled by setting references for still lower level perception (programs, like a “recipe for meatless breakfast”) and so on down to relationship perceptions (such as “coffee with [rather than after or before] breakfast”), event perceptions (“pour coffee”), etc. In other words, make sure your diagram can be understood in terms of higher level control systems controlling their perceptions by means of setting the references for lower level perceptions.

MT: I’m still jet-lagged and with a nasty cold, so apologies for probable incoherence.
RM: Hope you feel better soon.
MT: How does the larger hierarchy deal with the lack of metaphorical power in a particular control loop? (Rephrase: how does a higher-level control unit that needs the car to be on top of the hlll control its perception?) It might, for type 1, construct
a road to the top of the hill, after which the car would provide the driver with the ability to drive it to the top. For Type 2, the car might be fitted with a more powerful engine, the driver might look at a map and see that there is a less steep way to get
to the top, the driver might call a tow-truck, and so forth. Both Types involve the provision of different environmental feedback paths for that particular control loop. In our chapters fro LCS IV, Kent and I call these components of environmental feedback
loops “atenfels” (ATomic ENvironmental FEedback LinkS).
RM: Why the special (and rather ugly, in my judgement) name? What was wrong with plain old “feedback function”. It’s true that putting a more powerful engine in a car does change the feedback connection between your output and a controlled variable,
such as your speed. But all the hierarchy has done in this case is controlled for a perception of a more powerful engine. Once installed the engine does change the feedback connection between your output and speed. Which is a good observation but why does
it merit a new name for the feedback function?

Hey Rick, thanks.
BTW, noting what I actually wrote rather shocked me... or at least
the comment that I made. I had already noted that you stated that
you had not read the whole thing so my ‘…is so obvious…’ remark
must be understood as not having any reference to an opinion of your
comprehension!
Great point on the gaze heuristic. I did sort of ponder that for a
moment. I noted that I had not seen anything (even yet) on just
what that heuristic actually is beyond the loose reference to
'maintaining a constant angle.'Â Like yourself, is seriously doubt
that the fielder example is such a case or at least would typically
be such a case.
I don't know if this is 'way out on a limb' but I suspect that a
fielder probably controls head position and eye rotation in the
socket to do something like maintain the image of the ball centered
in the visual image. I think that it could well be more complex
than that where there might yet another object in the visual plane
that also must be tracked (where neither would be centered) but
essentially the changes in eye position and head position required
to maintain the ball at some referenced point in the full perceived
image would then be the input to yet another control system that
would, presumably through another heuristic, correct running
velocity to keep the ball’s visual position at the reference point
without the head or eye position sensors having to make changes.
I fully realize that even if what I just said about that is close to
what is true that it is still a gross oversimplification. Since
anyone that has successfully caught as opposed to falling down or
being hit by the ball realizes that in most cases the head has to
tilt back when the ball gets close to overhead just to see it.

RM: Yes, it is quite simple. I guess my problem was
not carefully reading the y-axis label: “Child care
received over 18 years (hours)”. I thought they were
just measuring “investment” using hours during
childhood, which I think lasts until 12 at most, so
that all kids are in the house at the same time. The
fact that they managed to measure hours over 18 years
for each kid is amazing. The study must have started
quite some time ago. Â
RM: So their hypothesis is simply that parents try
to control for spending an equal amount of time with
each kid. A side effect of this is that the first and
last kid get more time spent with them from birth to
18 years assuming that all kids move out at 18. So the
dependent variable in this study – child care
received over 18 years (hours) – is assumed to be a
side effect of controlling for equal time with each
kid.Â
RM: It seems that a far easier way to test this
“equal time with each kid” (1/N) hypothesis would be
to monitor the amount of time parents of 2, 3 or 4
kids spend with each kid, perhaps measured over a
month.Â
RM: I've seen this hypothesis about the controlled
variable before. It’s on the right track, but it
obviously can’t be gaze (angle of the eyes/head) that
is controlled; it’s got to be a consequence of the
direction of gaze – visual angle – that is actually
controlled. I think they choose gaze as the variable
that is controlled because they just can’t get their
heads around the fact that organisms control input,
not output.Â
RM: By the way, can you think of a way to show that
gaze is not the variable that is controlled when
moving to intercept a ball (or avoid a boat coming at
you)? Hint: it would involve doing the Test for the
Controlled Variable.Â

VH:
He says that the first born and last
born are alone with the parents for a
certain amount of time (41.30). So there
is an assumption the children are born
in sequence and then fly the nest in
sequence. This means N increases for
each born and then decreases as
children leave. For families with more
than two children the middle born are
never alone so the average N is always
higher for them than for the first or
last born.
VH:
Rick - what did you think of the “gaze
heuristic”?Â
