人类在面临涉及潜在收益和损失的选择时，会表现出不同的风险偏好。这些偏好被认为受到神经调节的影响，特别是多巴胺和5-羟色胺。由于神经调质表现出昼夜节律，这表明风险下的决策可能会受到一天中时间的影响。在这里，在使用智能手机应用程序收集的大型主题样本中，我们发现在一天中越来越多地选择具有潜在损失的风险选项。我们观察到这一结果在两个受试者内的设计（N = 2599），比较风险的选择在当天早些时候和晚些时候在同一个人，并在一个受试者间的设计（N = 26,720）显示我们的效果普遍跨越年龄和性别。使用计算模型，我们发现风险偏好的这种日变化反映了对损失增加的敏感性降低，但没有观察到收益和损失对选择的相对影响（即，损失厌恶）。因此，我们的研究结果揭示了人类决策的显著昼夜调节，这种模式对现实生活中的决策具有潜在的重要性，包括投票，医疗决策和金融投资。
Humans exhibit distinct risk preferences when facing choices involving potential gains and losses. These preferences are believed to be subject to neuromodulatory influence, particularly from dopamine and serotonin. As neuromodulators manifest circadian rhythms, this suggests decision making under risk might be affected by time of day. Here, in a large subject sample collected using a smartphone application, we found that risky options with potential losses were increasingly chosen over the course of the day. We observed this result in both a within-subjects design (N = 2599) comparing risky options chosen earlier and later in the day in the same individuals, and in a between-subjects design (N = 26,720) showing our effect generalizes across ages and genders. Using computational modelling, we show this diurnal change in risk preference reflects a decrease in sensitivity to increasing losses, but no change was observed in the relative impacts of gains and losses on choice (i.e., loss aversion). Thus, our findings reveal a striking diurnal modulation in human decision making, a pattern with potential importance for real-life decisions that include voting, medical decisions, and financial investments.
