The aim of this research is to examine whether the feedforward trajectory controller anticipates (and accounts for) impedance change produced by postural control mechanisms invoked later in the course of a planned motor sequence, or whether it adapts to them in the courses of practice. Specifically, we will test whether the feedforward control of single-joint slicing (out and back reversal) movements changes following extended training of reaching (point to point reaching) movements with elevated terminal agonist/antagonist muscle coactivation in a manner consistent with the invocation of a common feed forward motor command that transcends reaching and slicing tasks.
