我们的选择行为背后有一种共同货币，这一想法在行为科学中发挥了重要作用，从神经生物学到心理学和经济学。然而，虽然它主要是在价值方面进行了研究，有一个共同的规模，货物将被评估和比较，一个共同的规模的问题，特别是主观概率和信心，迄今为止只收到了很少的实证研究。本研究扩展了以前的工作解决这个问题，通过显示，信心可以在视觉和听觉的决定进行比较，在同一任务中的两个试验的比较具有相同的精度。我们讨论的可能性，信心可以作为一个共同的货币时，描述我们的选择，以自己和他人。
The idea of a common currency underlying our choice behaviour has played an important role in sciences of behaviour, from neurobiology to psychology and economics. However, while it has been mainly investigated in terms of values, with a common scale on which goods would be evaluated and compared, the question of a common scale for subjective probabilities and confidence in particular has received only little empirical investigation so far. The present study extends previous work addressing this question, by showing that confidence can be compared across visual and auditory decisions, with the same precision as for the comparison of two trials within the same task. We discuss the possibility that confidence could serve as a common currency when describing our choices to ourselves and to others.
