摘　　要：为了探索博彩行为与风险决策的特点,采用眼动研究方法对博彩行为中的风险决策任务进行了实验,结果发现:(1)外部框架表征虽影响决策者的内部表征,但决策者的内部表征方式表现出稳定的规律;(2)参与者在博彩中面对损失时,认知加工的决策时间比在面对收益的博彩任务的决策时间长,凝视次数也多比较多,决策者的瞳孔直径比面对收益任务下更大;(3)博彩参与者的内部表征方式,随博彩任务的外部表征的框架,金额、概率、备择项间倍数的改变而发生变化。结论:概率信息是博彩任务中的决策者稳定的决策权重;决策者在面对损失时会更加敏感,导致在决策过程中给予更多的加工负荷;博彩任务的外部表征对参与者内部表征有显著影响。To explore the characteristics of risk decision-making, the eye-movement technique was used. The results indicated that （1） although external representation influenced internal representation, internal representation showed its own characteristics; （2） compared with the profit situation, the gamblers took more time to make decision in the loss situation in gambling, and showed more gazing times and bigger pupil diameter; （3） the internal representation of the gamblers was changing with the external representation such as the amount of money, the probability, etc. The main conclusion is the information of probability is that the main factor in the decision making, gamblers who need to make decisions will be more sensitive to the loss, and the external representation has a significant effect on internal representation.
