A study on error feedback mechanism of motor learning system

运动指令和由此产生的动作错误之间的适当联系对运动学习至关重要，但这里的一项系统识别技术表明，这种时间关联在有节奏的动作中退化：过去不止一次试验中的运动错误影响甚至干扰了运动指令的纠正。我们证实了一个反直觉的预测，即间歇性的视觉错误反馈通过消除有害影响而不是连续的视觉错误反馈提高了视觉运动学习成绩。

Appropriate association between motor command and the resultant movement error is crucial for motor learning, but here a system identification technique revealed that such temporal association degraded in rhythmic movements : Movement errors in more than one past trials influenced or even interfered the correction of motor command. We confirmed a counterintuitive prediction that tntermittent rather than continuous visual error feedback boosted the visuomotor learning performance by removing the harmful effect.
