Building on an overview of dual systems theories in behavioural economics, the paper presents a methodological assessment in terms of the mechanistic explanations framework that has gained prominence in philosophy of the neurosciences. I conclude that they fail to meet the standards of causal explanations and I suggest an alternative ‘dual functions’ view based on Marr’s methodology of computational neuroscience. Recent psychological and neuroscience research undermines the case for a categorization of brain processes in terms of properties such as relative speed. I defend an interpretation of dualities as functional, without assigning them to specific neurophysiological structures.

从双重系统到双重功能：重新思考行为经济学的方法论基础

基于对行为经济学中二元系统理论的概述，本文根据在神经科学哲学中占据突出地位的机械解释框架提出了一种方法学评估。我得出结论，它们不符合因果解释的标准，并且我建议基于 Marr 的计算神经科学方法论的另一种“双重功能”观点。最近的心理和神经科学研究破坏了根据相对速度等属性对大脑过程进行分类的理由。我捍卫将二元性解释为功能性的解释，而不是将它们分配给特定的神经生理结构。
