The Influence Of Drug-Related Cues On Heroin Abstainers’ Risk Decision-Making

Risk decision-making is a process in which individuals have to make decision when they are faced with the two or more than uncertain outcome options.In the operational level,addiction is defined as although individuals may be asked to make other choice,but they will still make non adaptive choices.The study found that heroin addicts’ addictive behaviors were related to their risk decision-making.Drug addicts show a low sensitivity to long-term benefits and a high tolerance to risk options in risk decision making.Moreover,drug-related cues may influence the risk decision-making of heroin addicts.Previous studies have found the delay discounting decision is affected by money magnitude in cigarette and alcohol addicts.It is not clear that the risk decision-making is influenced by the reward magnitude and the effect of drug-related cues on their risk decision-making existed reward magnitude effect.This study used balloon analogue risk task to explore the reward magnitude effect on risk decision-making and the influence of drug-related cues to risk decision-making in heroin addicts.Therefore,the study is designed to explore that the effect of drug-related cues on their risk decision-making existed reward magnitude effect in heroin abstainers.The experimental 1 as the heroin abstainers and normal groups for subjects and explore that the effect of drug-related cues on their risk decision-making in 2 gains.The results show that heroin abstainers’ risk preference was not significantly different from the normal subjects,but the feedback learning performance is poorer than normal subjects.The effect of drug-related cues on risk preference and feedback learning is different from neutral cue.The experimental 2 as the heroin abstainers and normal groups for subjects and explore that the effect of drug-related cues on their risk decision-making existed reward magnitude effect.The results show that heroin abstainers’ risk preference level in the 25 gains is significantly higher than the 1 gains.The feedback learning performance in 1 gains is weaker than normal subjects,but the feedback learning performance as good as normal subjects in 25 gains.There were no significant differences in risk preference and feedback learning performance between the drug-related cues and neutral cue in 1 gains and 25 gains.Our conclusion is that(1)Heroin abstainers showed a low sensitivity to long-term benefits and a high tolerance to risk options in risk decision-making,but they would be affected by the reward magnitude(2)The feedback learning performance of heroin abstainers is poor,and it will be adjusted by the reward magnitude.(3)Drug-related cues had no effect on heroin abstainers’ risk decision-making,and there was no reward magnitude effect.
