Regret and disappointment have in common the fact that they are experienced when the outcome of a decision is unfavourable: They both concern “what might have been”, had things been different. However, some regret and disappointment theorists regard the differences between these emotions as important, arguing that they differ with respect to the conditions under which they are felt, and how they affect decision making. The goal of the present research was to examine whether and how these emotions also differ (...) with respect to the way in which they are experienced. Participants were asked torecall aninstance of intense regret or disappointment andto indicate what they felt, thought, felt like doing, did, and were motivated to do during this experience (cf. Roseman, Wiest, & Swartz, 1994). Significant differences between regret and disappointment were found in every category. These differences were most pronounced for “action tendencies” (what participants felt like doing) and “emotivations” (what they were motivated to do). These results suggest that the two emotions have differential implications for future behaviour. (shrink)

This article deals with the rationality and functionality of the existence of regret and its influence on decision making. First, regret is defined as a negative, cognitively based emotion that we experience when realizing or imagining that our present situation would have been better had we acted differently. Next, it is discussed whether this experience can be considered rational and it is argued that rationality only applies to what we do with our regrets, not to the experience itself. Then, research (...) is reviewed showing that both the anticipation of future regret and the experience of retrospective regret influence behavior. The influence of anticipated regret can be considered rational as long as the decision maker can accurately predict the regret that may result from the decision. The influence of experienced regret cannot be considered rational, since decisions should be based on future outcomes, not historical ones. However, influence of experienced regret can be called functional since it may result in increased learning from our mistakes. (shrink)
