The article Greg Williams put me on to,
Adams (1977), Feedback Theory of How Joint Receptors Regulate the
Timing and Positioning of a Limb, Psych. Rev. 84:504-523 contains,
among other things, a discussion of the `feedback too slow' issue (p. 519).
He attributes the original claim to Lashley 1951, who discusses a
piano player capable of executing of 16 movements per second (which
seems to me to be pushing it a bit for detailed control of these
movements by comparators above the spinal cord, given the reaction
time data that Adams cites when defending feedback).
Could somebody who has Schmidt 1982 _Motor Control and Learning_ in
a library accessible to them find out where he gets the claim? If it's
just Lashley's pianist again, it would begin to look like a classic
example of a non-sequitur repeated because somebody famous said it
first (non-sequitur because professional piano playing is not a
representative type of motor behavior).
Deafferentation is also discussed, making some of the points that
Bill made in his posting on the subject a while back.
This article is just the sort of thing I've been asking for, but since
1977 is gettig to be a fair while ago, has there been followup, or attempted
refutation of its substantive claims?
