According to prospect theory, reflection effects result in preferences for risk-averse choices in gain situations and risk-seeking choices in loss situations. However, relevant literature in regard to decision making has suggested that positive information receives more weight in a selection task, whereas negative information receives more weight in a rejection task. The present study examined whether the nature of a decision task (selection vs rejection) would moderate the reflection effects. Undergraduates (47 men, 49 women; M age = 20.5 yr., SD = 1.1), selected according to specific screening criteria, participated in an experimental study. Typical reflection effects were observed in both selection and rejection task conditions. More importantly, negative information (i.e., the information about probable loss in risky choice of gain situations and the information about certain loss in cautious choice of loss situations) provided in the context of a rejection task received more weight and resulted in more frequent endorsements of the cautious choice in gain situations and of the risky choice in loss situations. Hence, the findings suggest that a decision context characterized by rejection may expand the reflection effects and thereby provide important information about situations in which investment decisions occur in a context characterized by rejection.
根据前景理论,反射效应导致在收益情境中偏好风险规避选择,而在损失情境中偏好风险寻求选择。然而,有关决策的相关文献表明,在选择任务中正面信息权重更大,而在拒绝任务中负面信息权重更大。本研究考察了决策任务的性质(选择与拒绝)是否会调节反射效应。根据特定筛选标准选取的本科生(47名男性,49名女性;平均年龄 = 20.5岁,标准差 = 1.1)参与了一项实验研究。在选择和拒绝任务条件下均观察到了典型的反射效应。更重要的是,在拒绝任务背景下提供的负面信息(即收益情境中风险选择的可能损失信息以及损失情境中谨慎选择的确定损失信息)权重更大,导致在收益情境中更频繁地认可谨慎选择,在损失情境中更频繁地认可风险选择。因此,研究结果表明,以拒绝为特征的决策背景可能会扩大反射效应,从而为在以拒绝为特征的背景下进行投资决策的情况提供重要信息。
