人类的选择非常容易受到选项呈现方式的影响。这种所谓的“框定效应”明显违反了人类理性的标准经济学解释,尽管其背后的神经生物学并不为人所知。我们发现,框架效应与杏仁核活动特别相关,这表明情绪系统在调节决策偏差方面发挥了关键作用。此外,在个体中,眼眶和内侧前额叶皮质的活动预示着对框架效应的易感性降低。这一发现突显了将情感过程纳入人类选择模型的重要性,并表明大脑可能会如何将这些偏见影响的影响调节到接近理性的程度。
Human choices are remarkably susceptible to the manner in which options are presented. This so-called “framing effect” represents a striking violation of standard economic accounts of human rationality, although its underlying neurobiology is not understood. We found that the framing effect was specifically associated with amygdala activity, suggesting a key role for an emotional system in mediating decision biases. Moreover, across individuals, orbital and medial prefrontal cortex activity predicted a reduced susceptibility to the framing effect. This finding highlights the importance of incorporating emotional processes within models of human choice and suggests how the brain may modulate the effect of these biasing influences to approximate rationality.
