Challenge point framework surgeons). The optimal challenge point represents the degree of functional task difficulty an individual of a specific skill level would need to optimize learning (Guadagnoli and Lee 2004). However, this learning depends on the amount of interpretable information. Therefore, although increases in task difficulty may increase learning potential, only so much is interpretable, and task performance is expected to decrease. Thus, an optimal challenge point exists when learning is maximized and detriment to performance in practice is minimized. With increased practice it is assumed that one's information-processing capabilities will increase (Marteniuk 1976). Therefore, the optimal challenge point will change as
