control requires the generation of a precise temporal sequence
of control signals sent to the skeletal musculature. We describe
an experiment that, for good performance, requires human
subjects to plan movements taking into account uncertainty in
their movement duration and the increase in that uncertainty
with increasing movement duration. We do this by rewarding
movements performed within a specified time window, and
penalizing slower movements in some conditions and faster
movements in others. Our results indicate that subjects
compensated for their natural duration-dependent temporal
uncertainty as well as an overall increase in tempor
