方法75名大学生（18-27岁，M= 19.47，SD= 1.36; 52.63%的女性）和73名社区居住的老年人（58-91岁，M= 74.15，SD= 8.11; 70.15%的女性）参加了一项更大的研究（Strough，McFall，Flinn，& Schuller，在新闻中）。每一组包括一个涉及投资的小插曲和一个不涉及投资的类似小插曲。例如，其中一个投资小插曲说：“你花了10.95美元在付费电视上看电影。5分钟后，你感到无聊，电影似乎很糟糕。在无投资模拟中，关于10.95美元付款的句子被删除。这些插图改编自Frisch（1993）。一对小插曲涉及货币投资，另一个涉及时间投资;介绍顺序是平衡的。这两对被两个填充物晕影彼此分开。在每一组中，投资和不投资的类似物出现在相邻的页面上;它们的顺序在主题内部和主题之间是平衡的。在阅读每一个小插曲后，参与者选择五个选项中的一个作为未来的时间投资（例如，完全停止观看，再看10分钟，再看20分钟，再看30分钟，直到结束）。
METHODSeventy-five college students (18–27 years old, M= 19.47, SD= 1.36; 52.63% women) and 73 community-dwelling older adults (58–91 years old, M= 74.15, SD= 8.11; 70.15% women) who participated in a larger study (Strough, McFall, Flinn, & Schuller, in press) were presented with two pairs of vignettes. Each pair consisted of one vignette involving an investment and an analogous vignette involving no investment. For example, one of the investment vignettes said,“You paid $10.95 to see a movie on pay TV. After 5 minutes, you are bored and the movie seems pretty bad.” In the no-investment analogue, the sentence about the $10.95 payment was removed. The vignettes were adapted from Frisch (1993). One pair of vignettes involved a monetary investment, and the other involved a time investment; order of presentation was counterbalanced. The two pairs were separated from each other by two filler vignettes. Within each pair, the investment and no-investment analogues appeared on adjacent pages; their order was counterbalanced within and between subjects. After reading each vignette, participants selected one of five options for future time investment (eg, stop watching entirely, watch for 10 more min, watch for 20 more min, watch for 30 more min, watch until the end).
