尽管认知训练引起的脑功能变化已经被研究，但与特定训练策略相关的功能可塑性仍然相对未被探索。在这项研究中，我们研究了在使用太空堡垒视频游戏进行训练后，复杂的视觉运动任务期间大脑功能的变化。为了评估大脑功能，参与者在训练前和训练30小时后完成了功能磁共振成像(FMRI)，采用了两种训练方案中的一种：混合可变优先级训练(HVT)，重点是提高特定技能和管理任务优先级；或完全强调训练(FET)，参与者只是练习游戏，以获得最高的总分。对照组参与者只接受了6h的FET。与FET相比。HVT学习者在训练后在游戏中取得了更高的表现，在与视觉空间注意力和目标定向运动相关的区域显示出较少的大脑激活。与对照组相比，HVT组在右侧背外侧前额叶皮质(DLPFC)表现出较少的脑激活，同时表现出更大的成绩改善。感兴趣区分析显示，大脑活动的减少与任务表现的改善有关。这项研究揭示了与非定向训练(FET)相比，定向训练(HVT)改善学习的神经生物学机制，它与视觉空间注意和目标定向运动规划有关，同时分离了与执行控制和规则管理相关的基于实践的好处。(C)2012爱思唯尔B.V.保留所有权利。
Although changes in brain function induced by cognitive training have been examined, functional plasticity associated with specific training strategies is still relatively unexplored. In this study, we examined changes in brain function during a complex visuomotor task following training using the Space Fortress video game [22]. To assess brain function, participants completed functional magnetic resonance imaging (fMRI) before and after 30 h of training with one of two training regimens: Hybrid Variable-Priority Training (HVT), with a focus on improving specific skills and managing task priority, or Full Emphasis Training (FET), in which participants simply practiced the game to obtain the highest overall score. Control participants received only 6 h of FET. Compared to FET. HVT learners reached higher performance on the game and showed less brain activation in areas related to visuo-spatial attention and goal-directed movement after training. Compared to the control group, HVT exhibited less brain activation in right dorsolateral prefrontal cortex (DLPFC), coupled with greater performance improvement. Region-of-interest analysis revealed that the reduction in brain activation was correlated with improved performance on the task. This study sheds light on the neurobiological mechanisms of improved learning from directed training (HVT) over non-directed training (FET), which is related to visuo-spatial attention and goal-directed motor planning, while separating the practice-based benefit, which is related to executive control and rule management.
