摘　　要：采用ERP技术考察海洛因成瘾者相关线索下的用药行为的性质和神经机制,在此基础上结合虚拟现实技术(VR)和途径偏向矫正训练(AAT),探究基于“相关线索-习惯性用药”联结的自动化用药行为的动作消退、替代训练的有效性。研究发现,(1)相比对照线索,成瘾者在相关线索下的反应时更长,N1波幅更小,N1潜伏期更短;相比对照组被试,成瘾者在相关线索下的行为任务的正确率更低,反应时更长,N1波幅更小;N1波幅的组间组内差异和潜伏期的组内差异主要集中在中央区。(2)结合VR技术的途径偏向矫正训练后,训练组被试的生理指标和途径偏向系数显著降低,且显著低于对照组被试;追踪测试中,训练组被试的分数显著低于对照组。这表明相关线索下成瘾者的用药行为具有自动化、无意识的性质,感觉运动区N1的异常活动是其神经机制之一。VR提取用药动作记忆-AAT消退替代训练,可以有效削弱或消退成瘾者的成瘾动作倾向,而且训练效果持续性较好,可达到减少或停止现实情境中的用药和复吸行为的目的。Under relevant cues,people who are addicted tend to use drugs with little attention,purpose or cognitive effort,conforming to an automated“habitual”response behavior.When the substance is not available,this habitual response behavior will be transformed into psychological craving.A common goal of addiction treatment is to reduce cue-induced reactivity that has automatic and unconscious features.Based on previous research,this study used a self-report questionnaire,two behavioral experiments,and measures of Event-Related Potentials(ERPs)to explore the characteristics and neural mechanisms of cue-induced reactivity in heroin addicts under drug-related cues.On this basis,a training program using Virtual Reality(VR)technology and an Approach-Avoidance task(AAT)was designed to weaken the association between drug-related cues and automatic drug use behavior.In Study 1,the participants(N=38)were men who were addicted to heroin(n=19)and a matched sample of healthy controls(n=19).The Visual Analog Craving Scale(VAS)was used to investigate cue-induced reactivity by self-report.We then assessed ERPs to explore the nature and neural mechanism of cue-induced reactivity.We hypothesized that compared to the healthy controls,the participants who were addicted to heroin would show more cue-induced reactivity in the form of automatic response outside of awareness.Corroborating our hypotheses in Study 1,we proceeded to Study 2.N=60 men who were addicted to heroin were equally divided into a treatment group(n=30)and a no-treatment group(n=30).The treatment was VR-AAT training for 10 sessions over the course of two months,with the goal of reducing or eliminating cue-induced reactivity.Before and after the treatment,VR-AAT and the Craving Automatized Scale-Substances(CAS-S)questionnaire were used to test the difference between the two groups.The results showed that 1)In between-group comparisons,VAS scores were higher in the addicts than in the control group.And in Study 2,the within-group analyses showed that self-reports of drug
