摘要为寻求检验规范性和描述性风险决策理论的通用标准,本研究以期望价值理论和齐当别抉择模型为例,探讨了"迫选规则体验法"的适用性。被试为120名大学生,实验任务为要求被试分别完成自主决策(采用未知规则:真规则)和规则迫选决策(遵循给定规则:假规则)任务,并对决策后的情感和认可程度进行评定。研究发现:(1)被试在自主决策条件下比在规则迫选条件下体验到的正性情感程度更强,负性情感的程度更弱;(2)被试在自主决策与规则迫选决策两种条件下做出的相同决策越多,该被试对迫选规则更加认可并体验到的正性情感程度越强,负性情感的程度越弱;(3)与期望价值理论相比,齐当别抉择模型可能符合更多决策者的实际决策规则。这些结果表明,作为检验规范性和描述性风险决策理论的新尝试,迫选规则体验法可能更有助于回答"决策者实际采用的决策规则是什么"的问题。

附注In the field of decision theory,the tension between normative and descriptive theories has been a constant object of debate.The criterions used to evaluate normative and descriptive theories,however,differ from each other.This study sought a consistent criterion to evaluate both normative and descriptive decision theories and thus to explore the "true" rule of decision making.We hypothesized that(1) individuals would experience more positive emotions and show more acceptance when making decision according to their own rule("true" rule) than according to a pseudorule;(2) the greater number of the same decision derived from decision makers' own rule("true" rule) and the imposed rule,the more positive emotions and acceptance would be reported.To test these hypotheses,the expected value theory(normative theory) and the equate-to-differentiate theory(descriptive theory) were selected as two candidates of imposed rule.One hundred and twenty college students were asked to make risky choices according to their own rule(selfrule condition) and according to the two imposed rules(imposed rule condition),expected value rule and equate-to-differentiate rule,respectively.In the self-rule condition,participants rated their emotions after making choices according to their own rule.In the imposed rule condition,participants rated their emotions and acceptances of the two imposed rules after making choice according to the imposed rules.The order of the two imposed rules was counterbalanced across participants.We used the McNemar test to compare the decisions made under the self-rule condition and the imposed rule condition,and repeated measured ANOVAs to test the differences on emotion and acceptance ratings between the self-rule and the imposed rule conditions.The results revealed that(1) participants reported more positive emotion when making choices according to their own rules than to imposed rules;(2) the greater number of the same decisions derived from the imposed and "true" rules,the more acceptance and positive emotion reported by the participants;(3) equate-to-differentiate rule is more likely to be consistent with decision makers' true rule than expected value rule.These findings supported our hypotheses.As a new attempt to test normative and descriptive theories,the experiencing of imposed rule would possibly help us to better understand what the decision makers' true rule is.Considering that expectation rule is deemed as the soul of the dominant normative theories of decision-making under risk,our findings suggested that normative theories might fail to capture the nature of individuals' risky choice.In contrast,descriptive theories(e.g.,the equate-to-differentiate theory) seem to provide a better explanation to understand the actual mechanism of decision making under risk.
