The present mirror-drawing experiment was conducted over four months on one healthy female (R.H.) to elucidate the nature of the ipsilateral and contralateral learning curves for 12 sessions of unimanual training of the nonpreferred hand using a random practice schedule. Analysis indicated greater initial improvement for the practising nonpreferred hand with further improvements for both hands in number of errors and time to complete a single transfer test trial. A 4-mo, retention test showed the improvements were greater for the preferred (untrained) hand. Star-tracing records completed for both hands were quite similar to those recorded using the mirror after practice. This may reflect central processing and long-term potentiation influential even after practice ceased.
本次镜像绘画实验对一名健康女性（R.H.）进行了四个月，以阐明在使用随机练习计划对非优势手进行12次单手训练时，同侧和对侧学习曲线的性质。分析表明，练习的非优势手在初始时有更大的改善，在单次转移测试试验的错误数量和完成时间方面，双手都有进一步改善。为期4个月的保留测试表明，优势（未训练）手的改善更大。双手完成的星形追踪记录与练习后使用镜子记录的记录非常相似。这可能反映了即使在练习停止后，中枢处理和长时程增强仍然具有影响力。
