Overt motor preparation in choice-reaction time task.
In a serial pointing task to three unequidistant, unequiprobable targets, the moving picture record of the subject's hand movements shows, before each pointing movement, a repositioning of the hand near the median plane of the working panel when the subject sees the targets and near the more frequently used target when only proprioceptive information is available.
