Here's the Abbs & Winstein passage, from a section headed `Contributions
outside the closed-loop model' (p. 635):
"Technically, a _feedback_ sysem is one which an error signal directly
drives a corrective adjustment at the site where that error is
introduced. Recent experimental data indicate that many (or most)
important contributions of sensory informat to the on line control of
movement are not captured by this fundamental construct."
Then comes a list including `feedforward' as well as the `distributed
compensetory responses', which are obviously a form of feed_back_.
