Based on the COPE model, predictive models were created that could predict performance and four categories of errors and error tendencies. This chapter described how these predictive models were combined with a biofeedback method and were implemented into a feedback system. The feedback system was thereby able to provide bio- (physiological) feedback, predicted performance feedback and predicted error-chance feedback.
The primary use of this COPE-based feedback system or, COPE-FB system, was to provide support to professionals that train for working under stress.
