Document Summary

A skill is ability that an individual can improce over time through practice. Skills that depend on performing predefined movements that, ideally, never cay are called closed skills. Open skills are those that require performing movements in response to predictions about ongoing changes in circumstances. Practice can decrease the effects of previous experience on motor performance and increase the effects of genetic influences. Feedback about performance, or knowledge of results, is critical to the effectiveness of practice. The power law of earning states that with extended practice, the amount of time required to complete a task decreases at a diminishing rate. This law of diminishing returns holds for a wide range of cognitive and perceptual-motor skills. Massed practice, or concentrated, continuous ractice, generally produces better performance in the short term, but practice that is spaced out over several sessions leads to better skill retention in the long run.
