Amateurs practice until they get it right; professionals practice until they can’t get it wrong.
It may be beneficial to continue practicing something even after you’ve stopped improving. Overlearning takes place when an individual continues to practice beyond the point of mastery. One study indicates that overlearning can protect the memories from interference from subsequent learning in a process referred to as “hyperstabilization”. Studies have suggested that this effect may be relevant for motor and perceptual learning. Still, research in this area is limited, and the effects of overlearning on other types of learning have not been tested.
There is reason for caution with overlearning because it resembles massed practice , which has consistently been shown to be an inferior strategy to distributed practice . Overlearning may lead to a false sense of fluency . Until more research is available, it is probably best to combine overlearning with other learning strategies that have stronger evidence of efficacy.
