两个实验实施和评估的培训计划，学习应用频率格式的概率判断表达的百分比。结果表明，条件和累积概率的判断，可以提高以这种方式，但该计划是不够的，以促进任何更深入的理解的问题结构。在这两个实验中，只对一种问题类型（条件或累积风险判断）进行训练，导致在测试中学习方法的不适当转移。讨论了基于频率的培训方案所面临的障碍，用于教学适当使用概率数据。版权所有（c）2006约翰威利父子有限公司。
Two experiments implement and evaluate a training scheme for learning to apply frequency formats to probability judgements couched in terms of percentages. Results indicate that both conditional and cumulative probability judgements can be improved in this manner, however the scheme is insufficient to promote any deeper understanding of the problem structure. In both experiments, training on one problem type only (either conditional or cumulative risk judgements) resulted in an inappropriate transfer of a learned method at test. The obstacles facing a frequency-based training programme for teaching appropriate use of probability data are discussed. Copyright (c) 2006 John Wiley & Sons, Ltd.
