概率大小、损益结果和认知闭合需要对模糊规避的影响

模糊规避是指在相同奖赏的情况下,决策者会力图规避从主观上判断具有模糊概率的事件而偏好具有相同精确概率的事件。本研究探讨了概率大小、损益结果和认知闭合需要对模糊规避的影响。研究发现,在小概率受益的情况下,个体倾向于模糊寻求;在中概率受益的情况下,个体倾向于模糊规避;在高概率受益的情况下,个体倾向于模糊规避;在小概率损失的情况下,个体倾向于模糊规避;在中概率损失的情况下,个体倾向于模糊规避;在高概率损失的情况下,个体倾向于模糊寻求。但是,研究并未发现认知闭合需要对模糊规避有预测作用。

The Influence of the Magnitude of Probability, Loss-Gain Outcome and Need for Cognitive Closure on Ambiguity Aversion

Ambiguity aversion refers to the phenomenon that people prefer events with known probabilities to similar ambiguous events where the decision maker does not know the values of the probabilities.This research investigates the influence of the magnitude of probability,loss-gain outcome and need for cognitive closure on ambiguity aversion.The results of our research show that individuals tend to seek ambiguity when the probability of gain events is small;individuals are subject to ambiguity aversion when probability of gain events is moderate;individuals are liable to ambiguity aversion when the probability of gain events is large;individuals are inclined towards ambiguity aversion when probability of loss events is small;individuals are subject to ambiguity aversion when probability of loss events is moderate;individuals tend to seek ambiguity when probability of loss events is large.However,there does not exist significant relationships between need for cognitive closure and ambiguity aversion.
