Abstract
We review practice-induced changes in two variance components defined based on the uncontrolled manifold hypothesis. One of them affects task performance, whereas the other one does not. Practice leads to a drop in the former component (higher accuracy), whereas the latter can drop, stay unchanged, or even increase. The last scenario can be achieved with practice that challenges performance stability.
摘要
我们回顾了基于非控制流假设定义的两个方差分量的实践诱导变化。其中一个影响任务表现，而另一个则不影响。练习导致前一个分量（更高的准确性）下降，而后者可能下降、保持不变，甚至增加。最后一种情况可以通过挑战性能稳定性的练习来实现。
