决策任务反应模式对偏好反转的影响

在经典彩票问题研究的基础上,探讨了匹配和选择两种反应模式及其先后顺序对被试偏好反转的影响,以及被试性别与其偏好反转的关系。研究结果发现:(1)反应模式的变化导致偏好反转的发生;(2)偏好反转存在反应顺序效应,先匹配后选择条件下的偏好反转率显著大于先选择后匹配条件下的偏好反转率;研究结果不支持后悔理论;(3)不同性别被试在选择和匹配任务中的偏好及其反转率没有显著性差异。

THE IMPACT OF DECISION-MAKING TASK RESPONSE MODEL ON PREFERENCE REVERSAL

The present study explored the impact of response models(choosing and matching)and their order on preference reversal.The present study also explored the relation between subjects’ gender and their preference reversal.The study found that:(1)It appeared preference reversal phenomenon when the two response models were changed.(2)There existed response order effect on preference reversal,preference reversal ratio in this decision model(matching-first and choosing-second)was significantly bigger than another decision model(choosing-first and matching-second).The result didn’t support regret theory.(3)There was no significant difference between male and female subjects’ preference and their reversal ratio in different response models(choosing and matching).
