What relative frequency of KR or KP is least beneficial for motor skill learning?

When considering the relative frequency of Knowledge of Results (KR) or Knowledge of Performance (KP) in motor skill learning, the option that indicates 100% frequency can be least beneficial. Providing feedback for every attempt at a task can lead to dependency on that feedback, hindering the learner's ability to self-evaluate and correct their movements independently.

In contrast, when feedback is given less frequently, such as at 50%, 75%, or 25% intervals, learners are encouraged to engage more actively with their performance, promoting a deeper understanding of their movements and fostering problem-solving skills. This intermittent feedback approach builds confidence and facilitates better retention of skills, as it pushes learners to assess their own performance and make adjustments without constant reliance on external guidance. As a result, while some feedback is advantageous, an excessive amount, like at 100% frequency, can ultimately impair the learning process.
