我们报告了三个实证研究，旨在澄清为什么个人误解存量和流量之间的关系。我们测试了对问题类型的熟悉程度、解决问题的动机或问题的图形表示是否会影响参与者对库存和流量关系的理解。我们得出结论，对存量和流量的误解是人类推理中普遍存在的重要问题。领域熟悉度和动机的增加都不能改善个体对存量和流量关系的感知；但图表似乎把注意力引向了资金流，而不是库存量，为后来的错误埋下了隐患。个人关注图表中最突出的点，而不是理解随着时间的推移整体积累。未来的研究需要调查问题表示的几个方面，例如使用物理或文本而不是图形表示。版权所有©2007 John Wiley & Sons， Ltd
We report three empirical studies intended to clarify why individuals misperceive the relationships between stocks and flows. We tested whether familiarity with the problem type, motivation to solve the problem, or the graphical presentation of the problem affected participants’ understanding of stock and flow relationships. We conclude that the misperceptions of stocks and flows are a pervasive and important problem in human reasoning. Neither the domain familiarity nor increased motivation helped individuals improve their perception of stock and flow relationships; but it seems that the graphical representation directs attention to flows and not stocks, setting the stage for subsequent mistakes. Individuals attend to the most salient points of a graph rather than comprehending the overall accumulation over time. Future research needs to investigate several aspects of the problem representations, such as the use of physical or textual rather than graphical representations.
