许多决策涉及到对事件结果的一定程度的个人控制，这是通过一个人的知识或技能来实现的。在三个实验中，我们研究了基于a）随机事件的结果和B）控制事件的结果的前景之间的决策差异。在实验1中，参与者根据随机事件或他们在概率谱上对美国州人口问题的答案的正确性来估计赌注的确定性等价物（CE）。在实验2中，参与者根据随机事件、美国州人口问题的答案或2007年NCAA足球比赛结果的答案来估计投注的CE。实验3采用被试内设计，扩展了与实验1相同的程序。我们在一个前景理论框架中对所有实验的数据进行建模，以建立决策行为背后的心理机制。参与者加权的概率与投注的特点是控制，以反映更大的风险吸引力相对于投注的基础上随机事件，证明了更高的加权函数的控制条件下。这项研究阐明了可能的认知机制背后增加风险的决策特征的控制，和各种文献的影响进行了讨论。
Many decisions involve a degree of personal control over event outcomes, which is exerted through one’s knowledge or skill. In three experiments we investigated differences in decision making between prospects based on a) the outcome of random events and b) the outcome of events characterized by control. In Experiment 1, participants estimated certainty equivalents (CEs) for bets based on either random events or the correctness of their answers to U.S. state population questions across the probability spectrum. In Experiment 2, participants estimated CEs for bets based on random events, answers to U.S. state population questions, or answers to questions about 2007 NCAA football game results. Experiment 3 extended the same procedure as Experiment 1 using a within-subjects design. We modeled data from all experiments in a prospect theory framework to establish psychological mechanisms underlying decision behavior. Participants weighted the probabilities associated with bets characterized by control so as to reflect greater risk attractiveness relative to bets based on random events, as evidenced by more elevated weighting functions under conditions of control. This research elucidates possible cognitive mechanisms behind increased risk taking for decisions characterized by control, and implications for various literatures are discussed.
