Twenty-two trainee surgeons were tested on high level tests of intelligence, a detailed battery of paper-and-pencil and computerized spatial ability tests, and personality tests. They were also rated for operating ability, clinical decision-making ability, and for overall performance by consultant surgeons who knew them well. Ability ratings were high, indicating very little dissatisfaction with the performance of trainee surgeons. There were no significant correlations between surgical ability ratings and intelligence test scores. The only significant correlation between spatial ability and ability ratings was with one subtest, and was in the opposite direction to that expected. Trends in the data suggested that those trainees rated as superior tended to be more introverted and conscientious, and tended to have better stereoscopic depth perception. The discussion questions the necessity for aptitude testing in surgery and points out some statistical pitfalls in the area. It is concluded that little advance may be made with the application of aptitude testing in the selection of surgeons until there are more objective criteria of surgical ability in different surgical specialties.
22名实习外科医生接受了高水平智力测试、一系列详细的纸笔和计算机化空间能力测试以及性格测试。他们还由非常了解他们的顾问外科医生对手术能力、临床决策能力和整体表现进行评分。能力评分很高，表明对外科实习医生的表现几乎没有不满。手术能力评分与智力测试分数之间没有显著相关性。空间能力与能力评分之间唯一显著的相关性存在于一个子测试中，且与预期方向相反。数据趋势表明，那些被评为优秀的实习生往往更内向、更有责任心，并且往往具有更好的立体深度感知能力。讨论对手术中能力测试的必要性提出了质疑，并指出了该领域的一些统计陷阱。得出的结论是，在不同外科专业有更多客观的手术能力标准之前，在外科医生选拔中应用能力测试可能不会有太大进展。
