Police martial arts is the key of the public security actual combat training, it is also the important training content of police colleges and universities, on-the-job police training and after the induction training. The physical quality and motor-skill performance of the police can be proved by martial arts training. However, it is not clear whether martial arts training can prove the core mental quality of the police. The police under different stress conditions of martial arts skills selection criterion is also not perfect. They may encounter all kinds of emergencies and dangers in the process of law enforcement. In order to ensure the finish of tasks and the safety of themselves, it is more important to improve the scientific choice of motor skills and mental quality than physical quality alone. Traditional mental training of the police needs specialized psychological training while recently, researches have reveal that physical activities play an important role on improving cognition. The present study is aimed to reveal the advantages of core mental quality in the police. Expert interviews and literature analysis methods were adopted firstly to rule out the scope of core mental quality in the police and eventually determined inhibition and shifting ability as the core mental quality in the police. Also, it is very important to keep a stable core mental quality under the pressure and negative emotion for excellent police.In order to reveal the advantages of the police on the core mental quality and explore the related mechanisms, the present study adopted the classic experimental psychology method, and introduce the event related potential technology. A negative emotional situation were also used in the experiment to enhance the ecological validity. Stroop task, Go/NoGo task and alternating-runs paradigm were adopted to measure the ability of cognitive inhibition, behavior inhibition and cognitive shifting.The results of the study were as follows:(1) The choice of applicable police martial arts skills and design should be based on the benefit of law enforcement in poll;ice actual enforcement combat. To ensure the high survival rate, the maximum success rate of movement performance, the smallest physical and mental energy consumption and minimum response and response time are four principles of police in fight with violent confrontation against laws. The psychological stress of different police law enforcement officers have different effects on different types of police martial arts performance.The choice of police martial arts skills is depended on the resistant of the law enforcement object and the pressure of the police.(2) The core mental quality of elite police included excellent inhibition and shifting ability, as well as the characters to maintain the abilities under pressure.(3) Compared with the controlled group, the police undertook martial arts training were more accurate on the Stroop task, they were more efficient on cognitive inhibition, reflected energy-saving advantages.(4) The police undertook martial arts training were more accurate on the NoGo trails under the negative emotional situation and consistent with the neutral emotional conditions, they input more cognitive resources on behavioral inhibition.(5) The police undertook martial arts training were better on the shifting process. They were less influent by emotions. Comprehensive the above results, the present research reveals police martial arts training not only improve the physical quality of trainer, it also improve the core mental quality by improving the ability of cognitive inhibition, behavioral inhibition and shifting processing. |
