摘要: 研究以Ellsberg选瓶任务为决策材料,探讨了不同任务特征下个体不确定性容忍度对模糊决策中决策偏好的影响。结果发现,获益情景下:高概率时高、低容忍度个体对模糊选项的选择无显著差异,均偏好模糊规避;中概率时低容忍度个体比高容忍度个体表现出更低程度的模糊规避,前者倾向于模糊中立,后者倾向于模糊规避;低概率时两者对模糊选项的选择无显著差异,均倾向于模糊中立。损失情景下:高概率时两者对模糊选项的选择无显著差异,均倾向于模糊寻求;中概率时低容忍度比高容忍度个体更偏好模糊寻求,前者倾向于模糊寻求,后者倾向于模糊中立;低概率时两者对模糊选项的选择无显著差异,均倾向于模糊规避。这表明,不确定性容忍度对模糊决策偏好产生作用,但这种作用会受到损益概率和损益结果的影响,具有情景依赖性。

Abstract: This research investigated the influences of tolerance of uncertainty(TU) and other variables on decision preference in ambiguity decision-making. The results showed that when the probability was large or small, there was no difference between the high and low TU groups in choosing the ambiguous urn whether in the gain condition or in the loss condition. When the probability was large, they were both trend to avoid ambiguity in the gain condition and switched to seek ambiguity in the loss condition. When the probability was small, they were both subject to be ambiguity neutral in the gain condition and switched to avoid ambiguity in the loss condition. The participants with low TU showed significantly less ambiguity aversion compared with ones with high TU when probability of gain events was moderate, The former was ambiguity neutral, but the latter was ambiguity aversion; The participants with low TU were more likely to seek ambiguity compared with ones with high TU when probability of loss events was moderate, The former was ambiguity seeking, but the latter was ambiguity neutral. Taken together, these findings indicated that TU could influence ambiguity preferences and the influence was context-dependent.

Key words: tolerance of uncertainty, decision preference, ambiguity aversion, probability levels, individual differences
