中文摘要：

为了解工作记忆在易感性人格对药物成瘾者执行控制功能和抑制性影响过程中的调节作用，采用BIS和SSS量袁以及连续操作测验（CPT）、2-back任务、威斯康星卡片分类任务（WCST）对150名药物成瘾者和100名年龄、性别及智商相匹配的非药物成瘾者实施冲动性人格、认知控制功能测试。结果发现在2-back任务正确率（工作记忆）高低不同的情况下，注意冲动性人格特质得分对执行控制功能会产生不同的影响。这说明工作记忆在冲动性人格对抑制性的影响中具有调节作用。

英文摘要：

In order to evaluate the cognitive function of abstinent drug dependent individuals, and understand the modulation effect of working memory on the influence of vulnerable personality on the executive process function. BIS and SSS, CFT,2 -back task and WCST were used to measure 150 drug dependent individuals and 100 age, gender, education year and IQ matched non - drug using sam- pies. The results showed that attention impulsive personality has a different effect on the executive function in different scores of the 2 - back task accuracy. This indicates that working memory modulated the influence of impulsive personality on the executive process func- tion for drug dependent individuals.
