- Test conditions for a right-handed subject in the limb position matching task, Experiment 1. The vibrating cuff was applied to the dominant upper limb (in this case, the right shoulder). Then, each arm was moved, or "driven", by the experimenter, while the participant actively matched those movements with the opposite arm. In this manner, the right arm was vibrated both while it was actively matching and while it was passively driven.
