Intrinsic feedback is a performer's own impressions of their performance, e.g
how the muscles feel during a movement, what can be seen of the results of an action or a performer's emotional response to their performance
Extrinsic feedback tends to be more valuable to beginners as they may not have enough knowledge or experience to determine the quality of their own performance
Elite performers have enough experience to interpret intrinsic feedback so they are able to make use of both extrinsic and intrinsic feedback
