【摘要】：联合Simon任务又称社会Simon任务,通常用来考察人们在共同行动中同时表征自己和他人任务的能力。采用联合Simon任务范式考查冰毒成瘾者共同表征能力的变化情况,以及探讨共同行动者群体内外性及被试性别对其影响。研究分为两个部分:研究一采用3 (任务类型:标准Simon任务、单人Go/NoGo和联合Go/NoGo任务)×2(刺激反应位置一致性:一致、不一致)×3 (被试类别:短期戒断者、长期戒断者和大学生)混合实验设计,主要考查不同戒断时间的冰毒成瘾者共同表征能力变化情况,并与大学生样本进行比较。从强制隔离戒毒所抽取了 72名戒断短期(小于6月)和67名戒断长期(大于12月)男性冰毒成瘾者作为实验组,并从某大学抽取59名男性大学生作为对照组;研究二采用2 (共同行动者群体内外性:内群体成员(冰毒成瘾者)、外群体成员(大学生))×2(刺激反应位置一致性:一致、不一致)重复测量实验设计,主要探讨共同行动者是否来自于自己所在群体表现的共同表征能力的差异,从某女子强制戒毒所抽取了 30名冰毒成瘾者作为被试。结果显示:(1)短期戒断者、长期戒断者和大学生样本在标准Simon任务、单人Go/NoGo任务和联合Simon任务上的反应时和正确率差异均不显著;(2)在反应时上,大学生的刺激反应位置一致性效应最大,戒断长期者次之,戒断短期者最小,并且差异显著;而在正确率上差异不显著;(3)共同行动者来自于内群体条件下的反应时显著快于来自外群体条件,而在正确率上差异不显著;(4)在反应时上,共同行动者来自于内群体条件下的刺激反应一致性效应显著大于来自外群体条件;而在正确率上差异不显著;(5)在反应时上,女性被试的刺激反应一致性效应显著大于男性被试;而在正确率上差异不显著。研究结论:(1)冰毒成瘾者和大学生在联合Simon任务中均表现出共同表征能力,而大学生表现出更大的效应,冰毒成瘾者的共同表征能力受到一定程度的损伤;(2)随着戒断时间延长,冰毒成瘾者的共同表征能力表现出一定的恢复,但共同表征能力的改善可能需要更长戒断时间;(3)冰毒成瘾者与大学生之间的社会群体分类可以调节冰毒戒断者的共同表征能力;(4)女性冰毒戒断者的共同表征能力优于男性被试。
[Abstract]:The Joint Simon Task, also known as the Social Simon Task, is usually used to examine the ability of people to represent themselves and others simultaneously in common action. The changes of corepresentational ability of methamphetamine addicts were investigated by using Simon task paradigm, and the effects of coactor group and sex on them were discussed. The study was divided into two parts: the first study used 3 (task type: standard Simon task, single Go/NoGo task and combined Go/NoGo task) 脳 2 (stimulus response location consistency: consistent, inconsistent) 脳 3 (subject category: short-term abstinence; The mixed experimental design was designed for long-term abstinence and college students. The main purpose of this study was to investigate the changes of meth addiction in different withdrawal time and compare it with the sample of college students. A total of 72 short-term (less than 6 months) and 67 long-term (more than 12 months) male meth addicts were selected as experimental group and 59 male college students as control group. In the second study, we used 2 (internal and external characteristics of common actor groups: inner group members (meth addicts), outer group members (college students) 脳 2 (stimulus response location consistency: consistent, inconsistent) repeated measurement design, The main purpose of this study was to explore whether the common actors came from the differences in the common representation ability of their own groups, and 30 methamphetamine addicts were selected from a woman's compulsory drug treatment center as subjects. The results showed that there were no significant differences in response time and correct rate between short-term abstinents, long-term abstinents and college students on standard Simon task, single Go/NoGo task and joint Simon task. The consistency effect of stimulus response was the largest among college students, followed by long-term withdrawal, and the least short-term withdrawal, and the difference was significant. However, there was no significant difference in the accuracy rate (3) the reaction time of the common actors from the inner group condition was significantly faster than that from the outside group condition, while the correct rate difference was not significant in the reaction time. The consistency effect of stimulus response of female subjects was significantly higher than that of male subjects in response time, but there was no significant difference in correct rate between female and male subjects. However, there was no significant difference in the correct rate. Conclusion: (1) both methamphetamine addicts and college students showed common representation ability in the task of combining Simon, while college students showed greater effect, and the common representation ability of meth addicts was damaged to a certain extent) with the extension of abstinence time. The common representation of meth addicts showed a certain recovery. However, the improvement of co-representation may require a longer withdrawal time. (3) the social group classification between methamphetamine addicts and college students can regulate the common representation ability of meth abstinents. 4) the co-representation ability of female meth abstinents is better than that of male subjects.
