ABSTRACT
This chapter considers the role the educator, coach or therapist plays in providing movement-related information that supplements the feedback that is readily available from internal sensory sources. Perhaps the first important distinction that needs to be made concerning augmented feedback is the difference between knowledge of results (KR) and knowledge of performance (KP). KR is supplementary information that is given to the performer after completion of the movement and describes the outcome of the movement in terms of the movement goal. KP is information given to the performer that describes the quality of the movement pattern that led to the performance outcome. Summary feedback involves withholding feedback for a given number of practice attempts, with the optimal summary KR length being influenced by the complexity of the task to be learned and the skill level of the learner.
