To assess the underlying mechanism of visuomotor learning in children and its relation to the cerebral lateralization, intermanual transfer of learning was examined on a button-press task. The main experiment examined transfer of learning from one hand to the other for 36 right-handed 4-yr.-olds, 19 5-yr.-olds, and 8 adults. The experiment consisted of three phases. In the first and second of three phases, the subject performed the task with the right [(or left) hand, then with the left (or right)]. All age groups exhibited transfer from the left to the right hands; however, the 4-yr.-olds showed no transfer from the right to the left, whereas the other age groups showed transfer from the right to the left as well as left to right. Results were discussed in relation to the underlying mechanism of learning and hemispheric organization, and a new interpretation was proposed.
为了评估儿童视觉运动学习的潜在机制及其与大脑半球偏侧化的关系，我们在一个按键任务中研究了学习的双手间迁移。主要实验考察了36名4岁右利手儿童、19名5岁儿童和8名成年人从一只手到另一只手的学习迁移情况。实验包括三个阶段。在三个阶段的第一阶段和第二阶段，受试者先用右手（或左手）执行任务，然后用左手（或右手）执行任务。所有年龄组都表现出从左手到右手的迁移；然而，4岁儿童没有表现出从右手到左手的迁移，而其他年龄组则表现出从右手到左手以及从左手到右手的迁移。我们结合学习的潜在机制和半球组织对结果进行了讨论，并提出了一种新的解释。
