Bruce Gregory (979226.1715 EST) --
The truth at last. Perception = Model... Now that we know this,
everyone can see that MCT _is_ HPCT. Now perhaps we can move on...
Excellent observation. Now what we need is a law that limits the

people to look at turns out to seem to support Hans.
It doesn't gall me at all. But I don't think the data support Hans'
model yet (though they certainly don't reject it). A PCT model can
handle the data, too. So right now it seems to me that these
"tracking with predictable target" experiments might be a nice
basis for comparing the behavior of Hans' and the PCT models to
And I suppose it must be worse that you generated those data
Only because it makes me feel like I'm one of the only ones doing the
