摘要: Two experiments were conducted to determine if multi-frequency (2:1 and 3:2) coordination between the limbs is enhanced when integrated feedback provided in form of Lissajous plots, attention demands are reduced, attempts consciously coordinate not encouraged. To influence vision limbs, covered uncovered limb groups online feedback. impact feedback, a control group that was also tested. The data indicated remarkably effective performances after 5 min practice provided. When permitted, performance deteriorated. Performance by quite poor. findings suggest some difficulty associated with producing difficult bimanual patterns due less than optimal perceptual information available various testing situations attentional focus imposed participant.
