BACKGROUND
The present study was undertaken to determine if psychomotor and visual-spatial abilities improve as a result of surgical training or are enhanced at baseline in those individuals choosing a surgical career.
METHODS
Medical students entering a surgical field and practicing surgeons performed a series of neuropsychologic tests. Performance was compared between surgeon groups, as well as with normative aged-matched controls.
RESULTS
An age-related decline was noted in the performance of all exercises, with the medical student group outperforming the midcareer surgeons, who in turn outperformed the senior surgeons. Interestingly, however, all 3 groups significantly outperformed their normative control groups on some or all tasks.
CONCLUSIONS
Improved visual memory and psychomotor performance compared with normative controls appears to be present at baseline rather than resulting from surgical training. Decline in performance with age is observed, however, and this should be considered when an older surgeon is learning new visually complex procedures.
背景
本研究旨在确定心理运动和视觉空间能力是因外科培训而提高，还是在那些选择外科职业的个体中基线水平就有所增强。
方法
进入外科领域的医学生和执业外科医生进行了一系列神经心理学测试。比较了外科医生组之间的表现，以及与年龄匹配的正常对照组的表现。
结果
在所有测试项目中均观察到与年龄相关的能力下降，医学生组的表现优于处于职业生涯中期的外科医生，而后者又优于资深外科医生。然而，有趣的是，所有三组在部分或全部任务上的表现均显著优于其正常对照组。
结论
与正常对照组相比，视觉记忆和心理运动能力在基线水平就有所提高，而非源于外科培训。不过，随着年龄增长表现会下降，在老年外科医生学习新的视觉复杂手术时应考虑这一点。
