Abstract  

A large number of studies have shown that patient including addiction, ADHD, and pathological gamblers are more likely to make impulsive decisions. At present, the experimental paradigm used to investigate decision-making impulsivity is the delay discounting task in which participants should choose from either a small and sooner reward or a larger and later reward. With this task, psychologists have explored the neural mechanism of impulsivity in decision-making and proposed several theories including the single-valuation system theory, dual-valuation system theory, self-control theory and self-referential processing theory. Based on these theories, a variety of methods have been developed to reduce the impulsivity in decision making, including episodic future thinking, pre-commitment, improving the ability of working memory, and increasing the blood glucose levels. The neural basis of reducing the impulsivity of decision-making was generalized by the cognitive-control theory and value-representation theory. Finally, we proposed future research directions and implications of value computation, value system and multi-voxel pattern analysis in the domain of decision-making.
