Abstract： Drug addicts have decision-making defects, and show the characteristics of impulsivity, risk-taking, dysfunctional reward processing, and lack of signals in bodies. Neuroimaging studies have shown that abuse of addictive drugs may cause damage to some brain areas such as DLPFC, ACC, OFC, VMPFC, Amygdala, Insula, etc, that may be incur addicts' decision-making defects. Cognitive training is beneficial to improve individuals' decision-making ability, for instance, goal management training and mindfulness meditation can improve working memory, promote self-awareness and goal oriented behavior; while, noninvasive brain stimulation can directly change the active state of addicts' brain regions that related to decision-making, hence, the cognitive function related to decision-making is improved. All in all, in the future cognitive training and noninvasive brain stimulation still have a broad space to expand in the aspect of addiction intervention.

Abstract： " Addictive behaviors have brought serious harms to the individual and the society. The study on the time perspective of groups with addictive behaviors has become a new perspective to explore the emergence and development of addictive behaviors. The people who have past negative perspective orientation, present hedonistic and present fatalistic are more likely to have addictive behaviors while the orientation of future time perspective is a protective factor for addictive behaviors. It will not only reduce the occurrence of addictive behaviors but also benefit the recovery of the addictive behaviors. The behavioral mechanisms such as self-regulation, impulsive decision, and the neural mechanisms of the prefrontal cortex can help us understand the addictive behaviors deeply from the time perspective. Future researches can further explore the consistency and specificity of time perspective among different addictive behaviors, use longitudinal research methods to explore the dynamic process of addicts' time perspective, and Intervention in the time perspective of addicts, help addicts achieve a balance of time perspective by improving their future time perspective and reducing their orientations of past negative and present time perspective, which therefore, can help the addicts increase their abstinence.
