What role does affect play in economic decision making? Previous research showed that the number of items had a linear effect on the willingness-to-pay for those items when participants were computationally primed, whereas participants' willingness-to-pay was insensitive to the amount when they were affectively primed. We extend this research by also studying the impact of affect on nonmonetary costs of waiting for items to be displayed and of screening them in a computer task. We assessed these costs by asking participants how many items they desired to see before making their selection. In our experiment, the effect of priming on desired-set-size was even larger than on willingness-to-pay, which can be explained by the fact that the nonmonetary costs, waiting time, were real, whereas willingness-to-pay was hypothetical. Participants also reported their satisfaction with the choosing process and the chosen items; no linear or nonlinear relationship was found between the self-determined desired-set-size and satisfaction.
影响在经济决策中扮演什么角色？先前的研究表明，当参与者被计算启发时，物品的数量对他们对这些物品的支付意愿有线性影响，而当他们被情感启发时，他们的支付意愿对数量不敏感。我们通过研究影响等待物品显示和在计算机任务中筛选物品的非货币成本来扩展这项研究。我们通过询问参与者在做出选择之前希望看到多少物品来评估这些成本。在我们的实验中，启动对期望集大小的影响甚至比支付意愿的影响还要大，这可以用这样一个事实来解释：非货币成本（等待时间）是真实的，而支付意愿是假设的。参与者还报告了他们对选择过程和所选物品的满意度；在自我决定的期望集大小和满意度之间没有发现线性或非线性关系。
