风险偏好类型与风险判断模式的实验分析

测量了被试的风险偏好类型及其对一系列风险投资项目的风险判断值，从而分析风险偏好类型、任务结构与风险判断模式的特征之间的关系。研究发现有４种风险偏好。不同风险偏好类型、不同的风险判断任务结构会对风险判断模式产生不同的影响。双极值的任务结构与风险偏好的交互作用显著，而单极值的任务结构与风险偏好类型的交互作用不显著。被试的风险偏好类型在很大程度上影响了被试的风险判断模式。另外还讨论了影响风险判断偏差的一些因素以及任务结构对风险敏感度的影响等。

The Effects of Risk Preference and Task Structure Characteristics on Risk Judgment

This study examined subjects'risky preference styles and their behavior in risk judgment.The relationship among risky preference styles and task structrures and representation of risk judgments was analyzed.It was found that there were four kinds of risky preference styles and that the representation of subjects'behavior in risk judgment was depended on the risky preference styles and task structures.The interaction between the task structure of bipolar-ecpectancy and the risk preference style was significant,while the interaction between single polar-expectancy and risk preference style was not significant.Subjects'risk preference style affected the representation of risk behavior.Some factors affecting the bias in risk judgment and the relationship between task structure and risk sensitivity were further discussed.
