摘　　要：目的:探讨网络成瘾青少年的决策行为与冲动性。方法:根据中文网络成瘾量表修订版的诊断标准筛选出网瘾组23人,对照组22人;参考Rogers的冒险任务范式,对比两组被试冒险决策任务和冒险延迟任务的成绩。结果:(1)冒险决策任务中网瘾组做出高冒险、高奖励的选择次数显著多于对照组,且在冒险选择决策时思考时间偏少;冒险延迟任务中网瘾组的冒险和非冒险信心指数差值均显著大于对照组,网瘾组的冒险信心指数差值大于非冒险条件。结论:网络成瘾青少年在已知奖惩概率的冒险情境下,更倾向于做出高冒险高奖励的选择,且缺乏奖惩信息的冒险情境也容易促使网络成瘾青少年的冲动性行为。Objective： To investigate the characteristics of impulsivity and decision-making in adolescents with internet addiction. Methods： Twenty-three individuals with internet addiction and 22 without internet addiction were measured with the Risk-Decision Task and the Risk-Delay Task. Results： In comparison to the control group, internet addiction group had shorter deliberate time in the process of risky decision-making and also prefered making higher risky and rewarded choice in the Risk-Decision task. The internet addicts also showed significantly higher confidence index difference in risk situation than in non-risk situation. Conclusion： When in the risk situation that the outcome probabilities of winning and losing were explicitly provided, adolescents with internet addiction prefer making higher risky and rewarded choice, which may contribute to their impulsive behavior even though lacking of rewards and punishments information.
