Recent evidence indicates that reward value encoding in humans is highly context dependent, leading to suboptimal decisions in some cases, but whether this computational constraint on valuation is a shared feature of human cognition remains unknown. Here we studied the behaviour of n = 561 individuals from 11 countries of markedly different socioeconomic and cultural makeup. Our findings show that context sensitivity was present in all 11 countries. Suboptimal decisions generated by context manipulation were not explained by risk aversion, as estimated through a separate description-based choice task (that is, lotteries) consisting of matched decision offers. Conversely, risk aversion significantly differed across countries. Overall, our findings suggest that context-dependent reward value encoding is a feature of human cognition that remains consistently present across different countries, as opposed to description-based decision-making, which is more permeable to cultural factors.
最近的证据表明,人类的奖励价值编码高度依赖于情境,这导致在某些情况下做出次优决策,但这种对估值的计算限制是否是人类认知的共同特征尚不清楚。在这里,我们研究了来自 11 个具有明显不同社会经济和文化背景的国家的 n=561 个人的行为。我们的研究结果表明,11 个国家都存在情境敏感性。通过单独的基于描述的选择任务(即彩票)进行的情境操纵产生的次优决策无法用风险规避来解释,该任务包含匹配的决策报价。相反,风险规避在不同国家之间存在显著差异。总的来说,我们的研究结果表明,情境依赖的奖励价值编码是人类认知的一个特征,在不同的国家中始终存在,而基于描述的决策则更容易受到文化因素的影响。
