I just received this notice about this article. Haven't read it, but I
thought some of you might like to have a look and see how it fits (or
not) into PCT.

THE HAND IS QUICKER THAN THE EYE
When reaching for a moving object, people tend to overshoot the
object by a little bit. But overreaching is part of the brain's
strategy for catching erratically moving objects most efficiently,
according to the 15 October PRL. The researchers asked people to
use a computer mouse to track a moving target on a screen. A
subject's error in adjusting to changes in speed was lowest when
they led the object slightly with the mouse. The result suggests
one way the brain's visual-motor system compensates for the lag
time between perception and action.
