Performance feedback in sport can be classified into two categories: intrinsic and extrinsic.
Performers are given feedback on how they are performing.Knowledge of results or knowledge of performance can be either positive or negative.
Intrinsic feedback is the feeling of the movement as it is being performed.It is what the performer feels as they perform.
During or after a performance, external feedback is provided.Things that the performer can hear or see can come from teachers, coaches, team-mates and other people.A wheelchair basketball player can hear verbal feedback from a coach, comments from teammates, the response of the spectators and the referee's decisions.The player can see where the ball is going.
Knowledge of results focuses on the end of the performance, for example the performer's score, time or position.Terminal feedback can be thought of as the outcome of a performance.
