Movement initiation and control: abduction, adduction and locus of limb

Dextrals were timed in moving a peg from hole to hole, when the board containing the 13 holes was placed horizontally either across the midline or entirely to one or other side of the body. Either hand made movements in either direction. Both movement times (between holes) and resting times (within holes) were measured. Resting times (motor programming?) were better performance indices than the actual movement times. The superiority of the preferred (right) hand was greater when it operated on its own (ipsilateral) side of the body. Adductive movements were faster than abductive, which were easier to program when a limb operated ipsilaterally.
