You can�t beat experience, but you can cheat it

To the Editors:We thank Smith and colleagues for their positive

comments regarding our study. We certainly endorse thedevelopment of training curricula that are based upon asound evidence base and an understanding of theprocesses that underpin skill acquisition. Indeed, wehave been working with clinicians for a number of yearsto apply knowledge derived primarily from sports psy-chology and human movement science to the acquisi-tion and performance of laparoscopic skills.1-4 Althoughthe apprenticeship model may have served surgical train-ing well, there is increasing recognition that both a goodunderstanding of skill acquisition processes5 and anappreciation of the influence of stress on technicalperformance6 are important when designing effectivetraining. We also agree with the authors that ‘‘throwingmore money’’ at the problem of training (eg, high-fidelity, virtual-reality simulators) is not the onlyanswer---especially if there is no integrated, evidence-based strategy to guide their adoption.

We note that the authors raised concerns about ouruse of the phrase cheating experience. Our use of this lin-guistic ‘‘eye candy’’ may or may not trivialize the impor-tance of the findings, but given that we are now engagedin a positive dialogue about skill acquisition for surgery,the eye candy appears to have served its purpose: atten-tion has been drawn to the article and to the field ofinquiry in general. The title is more than just provoca-tive, however, because our research shows that traineescan achieve proficient levels of performance withoutnecessarily completing a criteria-based number of repeti-tions as part of a rigid training curriculum. Instead, theycan expedite or ‘‘cheat’’ the learning curve to achieveproficiency more quickly. Specifically, trainees in ourstudy did not waste time acquiring an expert-like visuo-motor gaze strategy by gaining experience from trialand error over many trials (as most experts do), butinstead were helped to apply an expert-like visuomotor

gaze strategy from the outset of learning---effectivelycheating experience.

Clearly, training in technical skills is only a small partof all that constitutes surgical training, so we acknowl-edge the limitations of gaze training. However, reachingproficiency earlier in the learning of basic technical skillsaffords the trainee more time to develop complex(and arguably more important) judgment anddecision-making skills. Indeed, research in skillacquisition has shown that complex decision making isbetter during motor performance when the motor skillshave been acquired implicitly, with few demands onworking memory.7,8 Such gains may be particularly im-portant in the current medical education climate, wherelegislation (eg, the European Working Time Directive)limits the time available for training. Making the bestuse of this time by augmenting the learning process isone way to ‘‘cheat’’ experience.
