Paper: "Thinking as the control of imagination..."

[From John Anderson (2009.10.08.0132 EDT)]

I ran across this paper this evening, and I wondered if anyone on CSGNET had seen it and could comment on it. (I have just skimmed through it.) One of its references is B:CP, and at least one of the figures is an elaboration on a PCT control system.

Pezzulo, G. & Castelfranchi, C. Thinking as the control of imagination: a conceptual framework for goal-directed systems. Psychological Research 73, 559-577 (2009).

Abstract: This paper offers a conceptual framework which (re)integrates goal-directed control, motivational processes, and executive functions, and suggests a developmental pathway from situated action to higher level cognition. We first illustrate a basic computational (control-theoretic) model of goal-directed action that makes use of internal modeling. We then show that by adding the problem of selection among multiple action alternatives motivation enters the scene, and that the basic mechanisms of executive functions such as inhibition, the monitoring of progresses, and working memory, are required for this system to work. Further, we elaborate on the idea that the off-line re-enactment of anticipatory mechanisms used for action control gives rise to (embodied) mental simulations, and propose that thinking consists essentially in controlling mental simulations rather than directly controlling behavior and perceptions. We conclude by sketching an evolutionary perspective of this process, proposing that anticipation leveraged cognition, and by highlighting specific predictions of our model.

Best to everyone…

The authors haven’t understood enough about PCT. Most of the problems
they mention are handled easily in a hierarchical control system model.
They mention my hierarchical model, but think it has a problem with
choosing which lower-level actions to produce to control higher-level
perceptions. They make the same mistake Turvey made years ago, in
thinking that control of a higher-level variable has to involve one and
only one lower-level situation. These people really haven’t grasped the
idea of control by adjusting the lower-level world as a means of
controlling the higher-level world; they’re still thinking in terms of
calculating the lower-level action needed to achieve the higher-level
result – the inverse kinematics and dynamics approach, which starts with
the highest-level goal and converts it into lower-level actions –
exactly the same “final common pathway” model Sherrington
proposed in the early 1900s – 1906 or so.

Thanks to Fred Nickols for finding the full-text version for us!

Thanks indeed.

I think their whole paper is anticipated in the concept of
Imagination Mode in B:CP. And as Bill points out, they simply haven’t
grasped the idea of hierarchy in control systems.

If Psychological Research accepts letters, one of us might point
this out – maintaining scholarly decorum, of course.

Let’s see, “one of us.” Hmm. Who might that be? I’ve got it!! I
nominate – wait for it ----

These people really
haven't grasped the idea of control by adjusting the lower-level
world as a means of controlling the higher-level world; they're still
thinking in terms of calculating the lower-level action needed to
achieve the higher-level result -- the inverse kinematics and
dynamics approach, which starts with the highest-level goal and
converts it into lower-level actions -- exactly the same "final
common pathway" model Sherrington proposed in the early 1900s -- 1906 or so.

Yea! That's what I thought, too. Gee, maybe I'm beginning to get it.

And might such a letter be signed by several respected scholars on this list?
