The purpose of this study was to investigate order-of-practice effects for the acquisition of a complex basketball skill in a bilateral transfer paradigm. The task required participants to dribble as fast as possible in slalom-like movements across six javelins and return to the initial position. Fifty-two right-handed school children (M age = 11.7years) practiced this skill in eight sessions over 4 weeks under one of two training schedules: (a) with the dominant hand, before changing to their nondominant hand (D-ND group), or (b) with the nondominant hand, before changing to the dominant hand (ND-D group). All tests were conducted with the right hand or the left hand only, and a transfer test was given with both hands alternating. The results of a retention test yielded significantly larger learning gains for the ND-D group as compared to the D-ND group. It is interesting that this performance advantage was independent of the respective hand tested. The same pattern of result was found in the transfer test, with significantly shorter movement times for the ND-D group with both hands alternating. Such order-of-practice effects for the acquisition of complex skills can be explained with hemispheric brain asymmetries for the processing of specific task requirements.
本研究旨在探讨在双侧迁移范式中，复杂篮球技能习得的练习顺序效应。任务要求参与者在六个标枪之间以类似障碍滑雪的方式尽可能快速地运球，并返回初始位置。52 名惯用右手的在校儿童（M 年龄=11.7 岁）在 4 周内进行了 8 次练习，分为两种训练计划之一：（a）先用优势手，然后再换非优势手（D-ND 组），或（b）先用非优势手，然后再换优势手（ND-D 组）。所有测试均仅使用右手或左手进行，并且进行了双手交替的转移测试。保留测试的结果表明，与 D-ND 组相比，ND-D 组的学习增益明显更大。有趣的是，这种表现优势与所测试的手无关。在转移测试中也发现了相同的结果模式，双手交替时 ND-D 组的动作时间明显更短。对于复杂技能的习得，这种练习顺序效应可以用特定任务要求的大脑半球偏侧化处理来解释。
