两个实验中，双手协调任务进行了正确的和转换的视觉反馈条件。参与者产生周期性的线条画图案，具有不同程度的协调稳定性，同时感知屏幕上正确或转换的轨迹视觉信息。将感知的运动方向与实际产生的方向分离的视觉运动变换应用于一个或两个肢体，从而产生不同程度的感知分组能力。变换后的反馈不影响最稳定的协调模式（同相），而不太稳定的协调模式（反相，特别是正交）的准确性和/或稳定性受益于特定的视觉反馈操作，即当连贯的分组视觉运动结构出现时，协调的质量显着提高。这些研究结果表明，知觉转换有助于产生更复杂的协调模式，从而强调了知觉-动作耦合在双手协调中的重要性。(C)2002 Elsevier Science B.

Two experiments are reported in which bimanual coordination tasks were performed under correct and transformed visual feedback conditions. Participants were to generate cyclical line-drawing patterns, with varying degrees of coordinative stability, while perceiving correct or transformed visual information of the trajectories on a screen. Visuo-motor transformations that dissociated the perceived movement direction from the actually generated direction, were applied to one or both limbs, resulting in varying degrees of perceptual grouping power. The transformed feedback did not influence the most stable coordination patterns (in-phase) whereas the accuracy and/or stability of the less stable coordination patterns (anti-phase and particularly orthogonal) benefited from particular visual feedback manipulations, i.e. when coherently grouped visual motion structures emerged, the quality of coordination improved significantly. These findings indicate that perceptual transformations aid the production of more complex coordination patterns, thereby underscoring the importance of perception-action coupling in bimanual coordination.
