决策受到问题情境的影响，问题的措辞影响人们的知觉和判断，框架效应就是其中的一种形式。框架效应是指对同一个问题，由于语义的不同导致人们做出了不同的决策和判断。Tversky和Kahneman提出框架效应的概念，由此引发了大量的研究。最近的研究越来越关注个体因素的影响以及框架效应在实际中的应用。情绪是影响决策的因素之一，在现实生活中，个体做决策时所处的情绪状态不尽相同，有时是积极的，有时是消极的，那么，在不同的情绪状态下，人们会摆脱框架的影响吗？风险偏好作为风险选择的关联因素，在不同条件下能够预测风险选择吗？本研究以610名大学生为被试，以亚洲疾病问题、金钱问题、牛肉属性问题为决策问题，使用自编材料启动被试不同的情绪状态，比较了积极情绪启动实验组、消极情绪启动实验组和中性情绪启动控制组的框架效应；同时，本研究考察了个体风险偏好（RPI）对框架效应的影响，验证了概率心理模型中关于个体偏好模式的假设。本研究得到如下结论：1. 采用信息激起方法，通过刺激材料组合所启动的情绪状态差异显著，达到了预期的情绪启动效果。2. 控制组的风险选择框架效应显著，被试在正面框架下风险回避，在负面框架下风险寻求；情绪影响正面框架，积极情绪和消极情绪使被试倾向于风险寻求；情绪不影响负面框架，被试在不同实验条件下均风险寻求；没有发现属性框架效应，情绪启动条件与属性框架选择没有关系。3. 积极情绪和消极情绪启动条件下，情绪强度影响的是被试的选择，而非被试的选择强度：情绪强度可正向预测风险选择，但不预测相应的风险选择强度。4. 在风险选择框架下，风险偏好指数（RPI）显著预测控制组的风险寻求行为，风险偏好指数越高，被试越风险寻求。积极情绪启动条件下，RPI显著预测正面框架下的风险寻求行为，风险偏好指数越高，被试越风险寻求。

Decision making depends on the context of the problem; Description of problem can induce one’s perception and judgment. Framing effect is an example: people often respond differently to different descriptions of the same problem. Framing effects as phenomena in decision making has been studied for more than 20 years especially from 1980s. More studies have turned to the individual differences and application of framing effects recently.Affect is an important component in decision making. Individuals in real life may have different affective status when they make a choice or decision, sometimes positive, sometimes negative however. Can human bypass framing in certain affect?Risk preference as an straight related concept on risk choice, can it predict risk taking in different conditions?The present study, taking undergraduates as subjects, by controlling positive, negative and neural/usual transient affect, investigated the effect size and changes of framing effects in Risk Choice Framing and Attribution Framing, investigated the influence of risk preference differences by RPI, testing the hypothesis of PMM’s risk preference model.The study reached the following results:1. Affect priming by irrelevant affect information had effective results expected.2. Framing effects was significant for controlling group, with high risk-averse in positive frame and high risk-seeking in negative frame. Affect influenced positive frame, but not negative frame. More risk-seeking was found under positive & negative affect within positive frame, no effect of affect on positive frame condition which is found high risk-seeking. No attribution framing or influences of affect on it was found.3. Under positive & negative affect，strength of affect positively predicted risk choice, not its strength.4. Risk Preference Index (RPI) is a good indicator for risk seeking for risk choice framing in neural-affect group. After positive-affect priming, RPI predicted risk-seeking under positive frame.
