Abstract: Inhibition control is considered to be one of the core components of executive function, specifically, it refers to the ability of an individual to suppress inappropriate behavior or irrelevant task information. Researchers generally classify inhibition control into two types, interference inhibition/interference control and response inhibition/behavioral inhibition. Impaired Inhibition control is generally considered to be the main features of some clinical diseases, such as Addiction, Attention deficit/hyperactivity disorder (ADHD), etc., therefore, it is widely valued by researchers. In recent years, more and more research has begun to focus on the relationship between motivation and inhibition control. The study found that monetary rewards can promote individual behavioral inhibition and enhance neural structural connections, and this effect changes as the reward amount increases. Few studies have examined the effects of punishment motivation on inhibition control. The only studies have not explored the impact of punishment magnitude on inhibition control and their relationship to individual reward and punishment sensitivity. Based on this, this study combines the Stroop task with the modified version of monetary incentive delay task (MIDT), using 4 (punishment magnitude: 0 yuan, 20 yuan, 100 yuan, 500 yuan) × 3 (task type: neutral , congruent, incongruent) experimental design to further supplement this issue. The results were as follows: (1) Whether they are neutral trials, congruent trials or incongruent trials, the monetary punishment not only reduces the behavioral reaction time of the participants, but also improves the accuracy rate; (2) The interference effect between the non-punishment condition (0 yuan) and the punishment condition (20 yuan, 100 yuan, 500 yuan) is not significant, and the interference effect between other different magnitude punishment conditions are also not significant. (3) The impact of monetary punishment on reaction time of incongruent trial is significantly negatively correlated with individual punishment sensitivity, but not with reward sensitivity. The results show that money punishment can promote an individual's general behavior, but does not increase the interference inhibition ability of the participants. At the same time, the impact of money punishment on cognitive behavior is closely related to its punishment sensitivity. On the one hand, the results of the study provide support for Gray's theory of reinforcement sensitivity, on the other hand, they provide a reference for the application of psychology and education
