Knowledge of Results vs Knowledge of Performance best describes which?

• A. Knowledge of Results describes the outcome; Knowledge of Performance describes movement characteristics that led to the outcome
• B. Knowledge of Results describes movement characteristics; Knowledge of Performance describes the outcome
• C. Knowledge of Results describes the timing of the next trial
• D. Knowledge of Performance describes the outcome

Answer: (A)

The key idea here is the difference between what the result was and how that result was produced. Knowledge of Results tells you about the outcome of a movement—did you achieve the goal or how close you were to it. Knowledge of Performance, on the other hand, provides information about the movement itself—the way the body moved, the technique, and the patterns that led to the result.

So the statement that Knowledge of Results describes the outcome and Knowledge of Performance describes the movement characteristics that led to the outcome is the best description. For example, after a throw, KR would say how far the ball went; KP would analyze the release point, grip, and arm motion that produced that throw.

The other options mix up these ideas or add aspects (like timing of the next trial) that aren’t about these two types of feedback.
