视觉动作适应中的学习、巩固和迁移

Learning,consolidation and transfer in visuomotor adaptation

视觉动作适应是一种特殊形式的动作学习,是视觉目标与动作目标发生分离时大脑进行视觉动作转换从而完成动作执行的过程。类似于一般的动作学习,视觉动作适应中也有典型的动作学习、动作巩固和动作迁移现象,但表现机制更为复杂。视觉动作适应的学习是在视觉目标与动作目标不匹配时,被试在连续或阻断的视觉反馈的指导下,通过形成新的视觉动作地图完成动作任务的过程。排除任务间的顺行干扰,动作视觉适应巩固就随着时间的增强而增强。在双手之间和效应器之间都可以发生视觉动作适应的迁移。

As a special former of motor learning, visuomotor adaptation dissociating the motor target and visual target requires visuomotor transformation processing in brain. Motor learning, consolidation and transfer axe found in visuomotor adaptation, which is more complicated than that in general motor learning. Under continuous or blocked visual feedback, the process forming a new visuomotor map in brain is called motor learning in visuomotor adaptation. Without anterior interferences, consolidation increases over time. Motor transfer happens in different hands as well as different effeetors.
