跨期选择——涉及权衡即时结果和延迟结果的决策——通常是在压力下做出的。然而,压力是否以及如何影响跨期选择仍然未知。我们对 142 名健康男性受试者进行了实验室压力或控制方案,并要求他们在压力后立即或 20 分钟后做出一系列跨期选择(产生四个实验组)。基于行为经济学和细胞神经科学的理论和证据,我们预测压力对跨期选择的双向影响,压力后立即不耐烦或当前偏见增加,但当受试者在 20 分钟后接受测试时,当前偏见或不耐烦减少。然而,我们的结果表明,在任何一个时间点,压力对跨期选择都没有影响,并且压力反应性的个体差异(压力激素水平随时间的变化)与跨期选择的个体差异无关。总之,我们没有找到对心理社会实验室压力因素影响跨期选择这一假设的支持。
Intertemporal choices - involving decisions which trade off instant and delayed outcomes - are often made under stress. It remains unknown, however, whether and how stress affects intertemporal choice. We subjected 142 healthy male subjects to a laboratory stress or control protocol, and asked them to make a series of intertemporal choices either directly after stress, or 20 minutes later (resulting in four experimental groups). Based on theory and evidence from behavioral economics and cellular neuroscience, we predicted a bidirectional effect of stress on intertemporal choice, with increases in impatience or present bias immediately after stress, but decreases in present bias or impatience when subjects are tested 20 minutes later. However, our results show no effects of stress on intertemporal choice at either time point, and individual differences in stress reactivity (changes in stress hormone levels over time) are not related to individual differences in intertemporal choice. Together, we did not find support for the hypothesis that psychosocial laboratory stressors affect intertemporal choice.
