结构学习表明，人类神经系统学习的一般规则可以应用于控制涉及类似结构的动作（例如，学习骑车时使用各种自行车）。这些一般规则可以促进在新奇但相关的情况下的技能习得（例如，一辆新自行车）。我们通过调查习得的书写不对称（在受过西方教育的人群中更容易向右和向下移动手）是否像结构学习预测的那样存在于非首选手中来验证这一概念。我们在描绘抽象形状时，在右撇子人群的双手中发现了这些不对称。然后，我们通过在左撇子人群中发现相同的结果，排除了生物力学的解释。这些发现为结构学习提供了支持，并解释了：(1)个体学习用非偏好的手书写的速度；(2)在自主运动控制组织中存在更高的抽象（与效应器无关）水平。
Structural learning suggests that the human nervous system learns general rules that can be applied when controlling actions involving similar structures (e.g. using a variety of bicycles when learning to ride). These general rules can then facilitate skill acquisition in novel but related situations (e.g. a new bicycle). We tested this concept by investigating whether learned asymmetries in handwriting (greater ease in moving the hand rightwards and downwards within Western-educated populations) are present in the non-preferred hand as predicted by structural learning. We found these asymmetries in both hands of a right-handed population when tracing abstract shapes. We then ruled out biomechanical explanations by finding the same results with a left-handed population. These findings provide support for structural learning and explain: (1) the rapidity with which individuals can learn to write with their non-preferred hand; (2) the presence of a higher abstract (effector independent) level within voluntary motor control organisation.
