Knowledge of performance
Knowledge of Results (KR) has been one of the most examined variables in motor learning. However, instructors provide usually information about pattern of the movement. Such information has been termed Knowledge of performance (KP). In this article the methodology of KP research is revised from the beginning. There are three ways of studing this feedback: 1) KP is based on the movement analysis; 2) The use of videotape as KP; 3) Kinetic and kinematic feedback.
KEY WORDS: Motor learning, extrinsic feedback, knowledge of performance
