Abstract

Five studies involving seven samples were conducted to examine the effects of sunk time in progress decisions. Previous research on sunk time in progress decisions has failed to control for completion effects. Studies 1a and 1b found strong evidence for completion effects and weaker effects for sunk time effects on probability of continuing. In Studies 2a and 2b, we expanded our sunk time scenarios to use multiple types. We found evidence for sunk time and completion effects on probability of continuing. An additional analysis, however, found that the sunk time effect was larger when the progress decision involved a goal focused on the accomplishment of a project (e.g., writing a paper for class), as opposed to a goal focused on enjoyment (e.g., watching a television show). Study 3 found that both sunk time and completion effects were present in progress decisions focused on the accomplishment of a project. These effects were present even when participants were informed that there was sufficient time to complete an alternative project. Study 4 failed to find a sunk time effect in a behavioral study, and Study 5 replicated Study 4 using a vignette format. Overall, these results provide some evidence of sunk time effects in progress decisions, but the effect appears to be small and may be due, at least partially, to completion effects.

涉及时间的进度决策:沉没成本或完工效应
我们进行了五项研究,涉及七个样本,以考察沉没时间对进度决策的影响。以往关于沉没时间对进展决策的影响的研究未能控制完成效应。研究 1a 和 1b 发现了完成效应的有力证据,而沉没时间对继续决策概率的影响较弱。在研究 2a 和 2b 中,我们扩展了沉没时间情景,使用了多种类型。我们发现了沉没时间和完成效应对继续学习概率的影响。然而,额外的分析发现,当进度决策涉及的目标侧重于完成一个项目(如为课堂撰写论文),而不是侧重于享受(如观看电视节目)时,沉没时间效应更大。研究 3 发现,沉没时间效应和完成效应都存在于以完成项目为重点的进度决策中。即使参与者被告知有足够的时间完成另一个项目,这些效应仍然存在。研究 4 未能在行为研究中发现沉没时间效应,研究 5 采用小故事的形式重复了研究 4。总之,这些结果提供了一些证据,证明在进度决策中存在沉没时间效应,但这种效应似乎很小,而且可能至少部分是由于完成效应造成的。

期刊介绍: The Journal of Behavioral Decision Making is a multidisciplinary journal with a broad base of content and style. It publishes original empirical reports, critical review papers, theoretical analyses and methodological contributions. The Journal also features book, software and decision aiding technique reviews, abstracts of important articles published elsewhere and teaching suggestions. The objective of the Journal is to present and stimulate behavioral research on decision making and to provide a forum for the evaluation of complementary, contrasting and conflicting perspectives. These perspectives include psychology, management science, sociology, political science and economics. Studies of behavioral decision making in naturalistic and applied settings are encouraged.
