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.
