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 explore the decision-making behavior and impulsivity of internet addiction adolescents. Methods: According to the revised diagnostic criteria of Chinese Internet Addiction Inventory, 23 addicts and 22 control subjects were screened out. According to Rogers’ paradigm of adventurous tasks, the scores of adventurous decision tasks and adventurous tasks were compared between two groups. Results: (1) Adventurous decision-making group had more risk-taking and rewarding choices than control group, and had less time to think when making risk-taking decisions. Adventurous and delayed decision- Risk confidence index differences were significantly greater than the control group, addiction group risk confidence index difference greater than non-risk conditions. Conclusion: Internet addiction adolescents tend to make high-risk and high-reward choices under the circumstance of knowing the probability of rewards and punishments, and adolescents with impulsive and punitive circumstances can easily promote the impulsive behavior of adolescents with internet addiction.
