Which of the following types of feedback provides knowledge of results?

Knowledge of results refers to feedback that provides information about the outcome of a movement or performance, indicating whether a goal was achieved. In this context, focusing on the accuracy of movements directly pertains to understanding the results of one's actions.

The choice that indicates the "number of accurate movements" serves as a direct measure of performance, allowing an individual to understand how well they executed a task in terms of success or failure. This feedback type is essential for evaluating the effectiveness of a technique and guides future practice by highlighting specific successes in achieving the desired outcomes.

In contrast, other options pertain to different aspects of feedback. For example, kinematic accuracy relates to the quality and mechanics of the movements rather than the final results. Directions for completing a movement provide guidance but do not inform about the effectiveness of the attempt. Similarly, decreasing the frequency of reports regarding movement accuracy relates to a change in the type or frequency of feedback rather than communicating specific results of performance. Hence, choosing the option that focuses on the outcome of the actions aligns perfectly with the concept of knowledge of results.
