在三个实验中，对未来健康和金钱的假设数量的选择表明，与规范的贴现效用理论相反，两个领域的时间贴现率或抵消延迟所需的年度价值增长百分比不同。领域独立性，定义为相对于每个领域内的一致性，健康和金钱贴现率之间的低相关性，不是由于健康和金钱的不同效用函数。与其他研究一致，这些结果表明决策域影响所使用的认知过程。尽管存在域名差异，但这两个域名之间还是有一些相似之处。健康和金钱决策都显示，对于短期延迟、小幅度和收益，折现率要大于损失。
In 3 experiments, choices for hypothetical amounts of future health and money showed that, contrary to normative discounted utility theory, the temporal discount rate, or annual percentage increase in value needed to offset a delay, differed for the 2 domains. Domain independence, defined as the low correlation between health and money discount rates relative to the consistency within each domain, was not due to different utility functions for health and money. Consistent with other research, these results suggest that decision domain affects the cognitive processes used. Despite this domain difference, there were some similarities between the 2 domains. Both health and money decisions revealed that discount rates were larger for short delays, small magnitudes, and gains as compared with losses.
