吸毒者与非吸毒者前瞻性记忆能力对比研究

The contrast study of prospective memory ability between drug addicts and normal persons

目的了解吸毒者(甲基苯丙胺滥用者)和非吸毒者在进行中任务的平均反应时、完成任务成功率和前瞻性记忆任务成绩等方面的差异。方法采用对比法分别选取了实验组60名甲基苯丙胺滥用者和对照组60名非吸毒者,实验素材为图片,前瞻性记忆任务类型为基于事件和基于活动。结果吸毒者和非吸毒者在基于活动的前瞻性记忆中有两个阶段的进行中任务平均反应时出现了显著差异。在基于事件的前瞻性记忆中一个阶段的平均反应时出现显著差异。在两种前瞻性记忆任务中都呈现出了吸毒者的平均反应时高于非吸毒者。进行中任务的成绩方面,吸毒者和非吸毒者在基于活动的前瞻性记忆中没有显著的差异;在基于事件的前瞻性记忆中,有两个阶段差异显著,表现出非吸毒者高于吸毒者的情况。吸毒者和非吸毒者在两种类型的前瞻性记忆任务成绩之间没有出现显著的差异。结论吸毒者和非吸毒者在进行中任务的平均反应时方面出现了较为显著的差异,在进行中任务成绩方面其差异性存在于基于事件的前瞻性记忆中。两者在前瞻性记忆任务的成绩方面没有显著差异。

Objective To study the difference in on-going tests'average reaction time,the success rate and prospective memory result between drug(methamphetamine)addicts and normal persons.Methods To select 60 methamphetamine addicts as experimental group and 60 normal persons as control group and the experimental material was pictures and the types of prospective memory were event-based prospective memory and activity-based prospective memory.Results In two stages of activity-based prospective memory and in one stage of event-based prospective memory,there were significant differences in on-going test's average reaction time between drug addicts and normal persons.In two types of prospective memory,the drug addict's average reaction time was higher than normal person's.In on-going test's success rate,there was no significant difference in activity-based prospective memory between drug addicts and normal persons.In on-going test's success rate,there were significant differences in two stages of event-based prospective memory between drug addicts and normal persons.The normal person's success rate was higher than drug addict's success rate.There was no significant difference in two types of prospective memory result between drug addicts and normal persons.Conclusion There was significant difference in on-going test's average reaction time between drug addicts and normal persons.Only in the event-based prospective memory,there was difference in on-going test's success rate between drug addicts and normal persons.There was no difference in the prospective memory result between drug addicts and normal persons.
