摘　　要：为分离言语表述的干扰,实验采用简单选择任务,通过2(图形框架)×2(跨期选择)×2(得失情境)被试内实验设计探讨得失情境下图形框架对个体跨期选择的影响。结果发现:(1)在突出时间条件下,被试更倾向于选择小而即时的选项,而在突出金额条件下,被试选择小而即时和大而延时的概率没有差异;(2)收益情境中,个体更多地选择大而延时的选项,而在损失情境中,个体选择即时损失的概率更高。结果表明,跨期选择中个体的决策偏好会随着得失情境及决策选项描述方式的变化而变化。In order to eliminate the influence of the language expression,the current experiment used the simple choice paradigm and set 2(graphical framework)×2(intertemporal choice)×2(gain-loss situation)within-subject design to explore the influence of the graph framing on the intertemporal choice in the gain or loss situation.The results showed that:(1)in the condition of highlighting time,the participants were more likely to choose the small but sooner option,while in the condition of highlighting money,there was no significant difference between the small but sooner option and the larger but later option;(2)in the money-gain condition,the participants chose larger but later option than small but sooner option,while in the money-loss condition,the participants preferred the small but sooner option.The results suggested that individual decision preference changes with the situation of gain and loss and the description of decision options.
