甲基苯丙胺依赖者戒断后对吸毒相关汉字线索的注意偏向

The attentional bias to methamphetamine-related cues of methamphetamine addicts after withdrawal

目的:利用成瘾Stroop任务测量甲基苯丙胺依赖者戒断后是否存在注意偏向。方法:采用NuAmps 40导事件相关电位系统,记录并比较甲基苯丙胺依赖者(研究组)与健康志愿者(对照组)(各12例)对3类汉字(包括毒品主要相关词、次要相关词、中性词)的反应时(reaction time,RT)及正确率。结果:两组对3类汉字的反应正确率之间无显著性差异;两组对3类汉字的反应时无显著性差异;ERP测试结果显示两组数据无显著性差异。结论:成瘾Stroop范式无法测量甲基苯丙胺依赖者戒断后是否存在吸毒相关汉字线索的注意偏向。

Objective： To assess the reliability of attentional bias across stimuli domains with the drug-related Stroop task of meth- amphetamine addicts after withdrawal. Methods： NuAmps 40 event-related potential system was used to compare the reaction drug-re- lated Stroop task was used to compare the reaction time in addict and normal group（ 12 cases in each group） for the three categories Chinese character including the main drug related, secondary drug related and unrelated. Results： The Correct rate between group for the three categories Chinese character had no statistical significance. The reaction time between group for the three categories Chinese character had no statistical significance. The ERP datebase between group had no statistical significance. Condusion： Methamphetamine addicts after withdrawal show no significant attentional bias with drug-related Stroop task to drug-related cues.
