对存量和流量关系的误解普遍存在，也是系统动力学中需要解决的一个重要问题。先前的研究表明，即使考虑相对简单的系统，个人在积累问题上也表现不佳，这种效应被称为存量流动（SF）失败。本研究探讨了领域经验在克服 SF 失败方面的影响。我们比较了医学生和未接受过医学教育的本科生在医学和普通领域积累问题上的表现。医学生仅在某些问题（包括一般领域问题）上比本科生表现更好，而在需要医学领域经验的问题上，他们的表现与本科生同样差。存量和流量问题的表现与医学教育持续时间或年龄之间没有相关性。因此我们得出结论，领域经验并不是克服 SF 失败的有力指标。版权所有 © 2010 约翰威利父子有限公司
Misperceptions of stock and flow relationships are pervasive and an important problem to solve in system dynamics. Prior studies have shown that individuals perform poorly on accumulation problems, even when considering relatively simple systems, an effect termed the Stock–Flow (SF) failure. This study examines the effects of domain experience in overcoming the SF failure. We compared performance of medical students and undergraduates with no medical education on accumulation problems in medical and general domains. Medical students performed better than undergraduates only in some of the problems (including the general domain problems), and they performed equally poorly as undergraduates in problems that required medical domain experience. There was no correlation between performance in the stock and flow problems and either duration of medical education or age. Thus we conclude that domain experience is not a strong indicator for overcoming the SF failure. Copyright © 2010 John Wiley & Sons, Ltd.
