摘　　要：以64名男性生理脱瘾后处于不同康复阶段的海洛因戒除者和30名男性无毒品依赖行为的社会招募人员为被试,采用Iowa赌博任务探讨了收益-风险并存情境中海洛因戒除者的冲动性行为模式。结果发现,相对于正常人群,海洛因戒除者表现出"即时收益优先"的决策模式和对高风险的耐受性,且该特征不随戒除期的延长而改善。该研究为解释海洛因戒除者不顾其潜在的严重不利后果仍维持其复吸行为的现象提供了实验证据。The study explored the impulsive reaction patterns of heroin abstainers during the different abstinence phases in win-risk coincidence situations with Iowa Gambling Task（IGT）.
