BACKGROUND
Previous research showing correlations between spatial ability and surgical skills has used participants in relatively early stages of training. Research in skill acquisition has shown that the role of cognitive abilities can diminish as skills become increasingly automatic. In this study, we explored the role of spatial ability in laparoscopic surgical skills in two groups, one experienced and the other relatively inexperienced.
METHODS
Subjects were recruited from two videoscopic courses: an advanced course for experienced surgeons and a laparoscopic urological surgery course attended by participants with relatively little laparoscopic experience. Three measures were obtained: spatial abilities, videoscopic experience, and operative skills.
RESULTS
A significant correlation (r = 0.393) was found between spatial ability and skills in the lower experience group but not among the experienced surgeons (r = 0.020).
CONCLUSIONS
The results are consistent with the prediction that the importance of spatial ability in performance of laparoscopic skills should diminish with experience.
背景
先前显示空间能力与手术技能之间存在相关性的研究使用的是处于相对早期训练阶段的参与者。技能习得方面的研究表明，随着技能变得越来越自动化，认知能力的作用会减弱。在本研究中，我们探讨了空间能力在两组腹腔镜手术技能中的作用，一组经验丰富，另一组经验相对不足。
方法
从两个视频课程中招募受试者：一个是针对经验丰富的外科医生的高级课程，另一个是腹腔镜泌尿外科手术课程，参与者的腹腔镜经验相对较少。获得了三项指标：空间能力、视频经验和手术技能。
结果
在经验较少的组中，空间能力与技能之间存在显著相关性（r = 0.393），而在经验丰富的外科医生中则不存在（r = 0.020）。
结论
结果与以下预测一致，即空间能力在腹腔镜技能表现中的重要性应随着经验的增加而降低。
