An Experimental Study Of The Common Characterization Of The Ability Of Ice Addicts To Change

The joint Simon task, also known as the social Simon task, is often used to examine the ability of people to co-represent their own and their partner's task at the same time in joint activities. Using the joint Simon task paradigm to examine the ability to form shared task representations of Methamphetamine withdrawal enrolled in compulsory detoxification, and to explore the impact of the Group membership and external and gender Combination type. The study is divided into two parts: Study 1 is a 3(task type: two-choice Simon tasks, single Go /NoGo task vs.joint Simon task )×2 (stimulus-response correspondence : corresponding vs.Non-corresponding trials)×3 (subject type: long-term withdrawal,short-term withdrawal vs. college students)mixed experimental design aimed at examining the change of co-representation of MA dependent individuals at different time of withdrawal, and conducts a comparative study with sample of college students.Subject groups comprised 72 MA abusers who recently initiated abstinence, 67 MA abusers who had initiated abstinence > one year taken from the compulsory isolation and treatment center and 59 non-substance abusing controls selected as the control group from the university. Study 2 is a 2(group membershipin-group co-actor vs.out- group co- actor)×2(stimulus-response correspondence:corresponding vs.Non-corresponding trials) repeated measurement design aimed at addressing the possibility of the modulation of action co-representation by social categorization, such as group membership, 30 MA dependents from women's compulsory detoxification center as subjects, and a college student as a false test.Results showed: The results showed that: (1) There was no significant difference in response time and correct rate between short-term withdrawal,long-term withdrawal and college student sample in standard Simon task, single Go / NoGo task and joint Simon task; (2) In the response time, the stimulus response consistency effect of college students was the largest, the long-term withdrawal was the second,and the short-term withdrawal was the smallest, and the difference was significant;the difference was not significant in the correct rate; (3) The response of MA was significantly faster when paired with a in-group participant, but the difference was not significant; (4) In the response time, the stimulus response consistency effect of MA who paired with a in-group participant was significantly greater than that of MA who paired with a out-group participant; (5) In the response time, the stimulus response consistency effect of female subjects was significantly greater than that of male subjects, while the difference was not significant in correct rate..The main conclusions were: (1) Methamphetamine withdrawal and healthy control group can also be in the joint Simon task according to the partners to adjust their actions, the common actors into their own actions, that show co-representation,but the health control group to show more Large effect, and Methamphetamine users had deficits in action co-representation to some degree . (2) With the withdrawal time prolonged, the co-representation ability of the methamphetamine withdrawal group showed a weak recovery, but the improvement of the co-representation ability may require longer withdrawal time. (3) the social classification between methamphetamine withdrawal and healthy control can modulates action co-representation through in-group and out-group. (4)the female abstinence combination of the co-representation is better than the male abstinence combination,the different sex can regulate the co-representation.
