时间压力对偏好反转的影响

The Impact of Time Pressure on Preference Reversal

文章旨在探讨时间压力对偏好反转现象的影响,研究中引入时间压力(无时间压力、有时间压力组)变量,并且在传统的标准偏好反转实验材料之外加入了极小概率博弈(L博弈),来探讨时间压力对偏好反转现象的影响。本次实验针对时间压力对偏好反转的影响进行了研究,研究结果表明,在选择任务中,当H-S配对时被试在有时间压力下作出的选择比在无时间压力下的选择更加倾向于回避风险,而在H-L和S-L配对中差异却不明显。在定价任务中,无论有无时间压力,H-S、H-L、S-L配对中被试的定价没有显著差异,都倾向于对风险博弈定高价。即是说,时间压力对偏好反转现象中选择任务有一定的影响,但是对定价任务的影响较小。

The purpose of this thesis is to discuss the impact of time pressure on preference reversal phenomenon. We add a long shot bet besides the classical preference reversal experiment. What＇ s more, a new variable --time pressure--has been introduced into this experiment to test whether time pressure has influence on preference reversal. It is shown in this experiment that in the choice task subjects under time pressure tend to avoid risk in contrast to those without time pressure under the H-S bet, which is not significant between subjects under the H-L or the S-L bet. In the price-making task, subjects under different partnership tend to make high prices on the risk bet no matter whether there is time pressure or not. In a word, time pressure has great influence on choice -making task, but has little influence on price-making task.
