Impulsivity in Heroin Abstainers: Reaction Pattern Based on the Delay-Discounting Task and the Iowa Gambling Task

Abstract

摘要： 以61名男性海洛因戒除者和32名正常成年男性为被试，探讨了海洛因戒除者在延迟折扣任务和Iowa赌博任务两种决策条件下的冲动性反应模式及其关系。结果发现，海洛因戒除者的决策行为受其对即时强化的超敏感性或“即时收益优先”模式控制，其高冲动性特质既表现为对强化物长远价值的非敏感性，又表现为对强化物潜在风险的耐受性；该类人群上述两方面的特征虽有一定关联，但二者分别反应了其行为冲动性的两个相对独立的维度，且具有跨戒除时相的相对稳定性
