This chapter discusses the various intervention strategies available to the practitioner for skill refinement. It turns to questions concerning what information should be depicted in a feedback statement to best assist the learner. Should practitioners tell learners what was done correctly, or should they focus on performance errors? Should performance errors be described, or would an explanation of how to modify the movement be more beneficial? How precise should information be? Determine whether the following augmented feedback statements are examples of knowledge of results or knowledge of performance. Augmented feedback serves three major functions: error correction, motivation, and reinforcement. Auditory feedback devices have been shown to have positive effects in correcting foot position in a bar exercise in dance. Using information from biofeedback, performers learn to alter and control their movements. Drills and equipment can provide performance feedback. While performance improved for both interventions, error amplification resulted in significantly greater improvement than the direct instruction method.
