Study On The Differences Of Soccer Players’ Decision-making In Different Emotional States

Decision-making is in every area of our life, there is also decision-making in sport. The ability to process information is essential for soccer players, as technology improving, determining factors of competitions are not only technology, physiological, tactical, but also emotion. Many studies show that emotion has multiple effects on cognitive activity, so emotion of athletes in training and competitions is important, because it’s affecting athletes’ judgment and decision-making. So it’s important to research the effects of emotion on decision-making.In this study, we use emotion priming and signal detection theory to research the differences of decision-making that athletes made in different emotional states. There are two groups, experts and development-skill, each group has seventeen subjects. According to the previous research, the picture in the cognitive decision-making task is defined as 1s, and the image of the intuitive decision-making task is 0.4s The task is to measure cognitive decision and intuitive decision in different emotion, and analyze the judgment standard by SDT.The results show that whether expert or development-skill, the percentage of passing under negative emotional state is significantly higher than shooting, and it’s opposite under positive emotional state, and expert group is less affected. SDT analysis shows that the judgment standard under positive emotional state is more relaxed, and is more stringent under negative emotional state, the judgment standard of expert group in cognitive decision is more stringent than development-skill group.Therefore, we concluded that soccer players prefer to choose passing under negative emotional state, it’s opposite under positive emotional state. And negative emotional state has more effect of cognitive decision than intuitive decision. Emotional states affect the judgment standard of decision-making, and it has no effect of discrimination.
