And I am extremely lousy at
maintaining the "correct" relationship between these perceptions; the
one that keeps the invisible cursor on target. . . .

I can get quite good at this (I can keep the cursor "tracking" the
invisible cursor pretty well).

These seem contradictory. What am I missing? I assume you have not tried
my alternate version in which the target, not cursor, disappears. In your
second sentence above, keep WHAT cursor tracking the invisible cursor?
Please clarify.

I just imagine the temporal pattern (I seem
to be imagining only the relevant perceptual charcteristic of the target).

How? Where does this imaginary temporal pattern come from? Isn't this
pattern a world-model?

By the way, (Bill Leach 950511.00:40 U.S. Eastern Time Zone) is correct in
his read on my position; in my view the "world-model" is a perception, not
an S-R system for generating responses. As such it simply substitutes for
sensory inputs as necessary; the rest is ordinary control.

Bruce

Sorry. Misprint. I meant invisible _target_. I did my own version of the
disappearing target experiment that you suggested; and you were right; it's a
LOT easier to track the invisible target with the visible cursor than to
track the visible target with the invisible cursor.

Isn't this pattern a world-model?

I would call the pattern itself a perception (an imagined perception); but I
agree that whatever _generated_ that perception is a "world model".
