风险偏好为什么是不稳定的？——后悔调节风险偏好的理论探索

Emotion is one of the most popular spots in recent decision making research, while regret is always being considered as the most relevant emotion with decision making. Current article firstly reviewed the literature of regret theory to date to profile the relation between regret and decision making under uncertainty through three mainlines: experienced regret, anticipated regret and regret orientation, respectively. And then, based on the theory of regret regulation raised by Zeelenberg recently, we came up with a theory of risk preference regulated by regret. Then three studies were conducted under the current framework, by using experiment, survey, and quasi experiment design. The major findings were below: In study 1, when playing ultimatum game, risk preference in decision making can be determined by experienced regret and anticipated regret of risk aversion, which made individual risk taking; In study 2, survey showed that risk orientation was negatively related with risk taking (health/safety, recreational and social); In study 3, when asked the Asian Disease Problem, risk preference can be determined by the coherence of the risk preference between the past decision and the current alternative. Individuals much more like alternative with the same risk preference of the past decision. A two way interaction was found, regret orientation, as a personality, was found as a moderator. Individuals with high regret orientation were more sensitive to the coherence of the risk preference than those with low regret orientation. Three studies provide fruitful evidences for the theory of risk preference regulated by regret in different prospective, show us the function of regret in decision making.
