The Influence Of Negative Emotion On Drug Addicts’ Interference Control Function

In recent years, the problem of damaged inhibitory control function of drug addicts and processing of negative emotion has become an important topic in the field of drug addiction research. Previous studies have shown that the interference inhibition of drug addict’s is impaired. Because of the interference inhibition is defined as individual’s ability to control the information and response which are independent of the present task execution. To investigate drug addicts’ ability of the main task execute and the ability of control the indifferent stimulus, it is contribute to us to understand drug addicts’ anti-interference ability when they in the face of the drug and other related stimulation and the relationship between their relapse behavior.The study of drug addicts found that compulsive drug seeking is the main characteristic of this kind of people. The main factor of the influence of one’s compulsive drug seeking is their ability of inhibitory control, in addition, it also significantly correlated with negative sentiment. Therefore, negative emotion also causes the compulsive drug seeking and it is the key factor for relapse behavior. A number of previous researches have shown that drug addicts exists negative emotion processing abnormal and negative emotion regulation deficit. The problem of negative emotion how to impact on the interference inhibition function of drug addicts is still unclear. Our present study tries to discuss the impact that negative emotion on the interference inhibition function of drug addicts based on two experiment models in the lab. It will be help us to make better explanation for the behavior of relapse after abstinence.This study includes two experiments. Experiment one used color-word Stroop paradigm to study investigates the interference inhibition function of heroin addicts,Experiment two used color-word Stroop paradigm, high and low arousal negative emotional pictures and neutral pictures to examines the interference inhibition function of heroin addicts affect by different emotional stimuli. The main results as follows:(1) The interference inhibition function of heroin addicts is damaged;(2) Negative emotion stimuli interfere with individual’s interference inhibition function;(3) Compared with the health subjects, heroin addicts with susceptibility to negative sentiment;(4) Negative emotion processing of heroin addicts is abnormal.
