摘要
关于运动技能两侧性迁移的机制主要有认知学说和肌肉激活学说,但对于两侧性迁移的特征与模式依然存在争议和不确定性。应用认知事件相关电位(ERP)对迁移的机制进行了研究。行为指标实验证实了两侧性迁移的发生和迁移不对称性的存在;通过训练掌握技能后,皮层认知电位也发生动态改变,反映了技能学习过程中认知加工的痕迹和适应性,这种变化在非练习手也出现相似的特征,从皮层动态变化结果证实了两侧性迁移的发生;通过运动准备偏侧电位(LRP)的测量,不支持通道模式对两侧性迁移不对称性机制的解释;技能熟练后所产生的最高波幅向C z区转移的特征以及LRP的正确激活,有可能成为评价技能形成和熟练程度的指标。
There are two kinds of hypotheses on bilateral transfer of motor skill, one is cognitive hypothesis and the other is neuromuscular activation. There still exists uncertain and dispute on character and model of bilateral transfer. In this paper, the author makes study on mechanism of bilateral transfer using the method of event-related brain potentials （ERP）. The behavior index experiments testify the asymmetry of bilateral transfer and occur. Through learning the skill, the cognitive potential also makes dynamic change, which reflects the adaptation of learning skill and cognitive process. The research result provides an important cognitive psychological evidence for the mechanism of bilateral transfer.
