| Tennis is a kind of anti-ball game that needs to make decisions.It has the characteristics of fast ball speed,falling point,line and rotation change.It also raises the decision-making ability of tennis players in the game.Claim.In college tennis,the decision-making judgment of the tennis return line is the key to achieving good results.The quality of decision-making is related to many factors,such as personality traits and emotions.The study uses different emotional states,different levels of self-control ability,and decision-making strategies as variables to explore the differences in the behavioral response time and judgment accuracy of college tennis players in judging the return of tennis balls.In this experiment,the decision-making experimental procedure of tennis ball return point judgment was edited by using the experimental software E-prime2.0software commonly used in psychology.At the same time,the SPCS physiological coherence and auto-balance system were used to collect the emotional experience process of the participants during the whole experiment.And the HRV-related physiological indicators of the decision-making process,to find out the differences in cognitive decision-making and intuitive decision-making under different emotional states and high and low self-control ability.The experiment consists of two pre-experiments and one formal experiment.The results of the analysis are as follows:(A)Behavioral data analysis results(1)In different emotional states,different control levels,different decision types,the response time and accuracy of decision-making tasks showed significant differences,and the main effect was significant;(2)the influence of emotions on different self-control levels failed to be presented.Differences occur and the interaction effect is small.(3)The interaction between the level of self-control and the type of decision-making is significant,and the impact is particularly prominent.(4)In the interaction of emotional state and decision type,there is a significant difference in the response to decision-making tasks,but the interaction is not significant in accuracy.(B)HRV physiological indicators analysis results(1)The number of physiological indicators in M-HRT,PNN50 and LF/HF showed significant differences under different experimental conditions.(2)M-HRT resultsshow that the average heart rate in positive emotional state is higher than that in negative emotional mood;the heart rate of college tennis players with high self-control ability is higher than that of low self-control athletes;decision-making process center The rate changes a lot.(3)It can be seen from the PNN50 results that the mean value in the positive emotional state is higher than the mean value in the negative emotional state;the college tennis player with high self-control level has a mean value higher than the tennis player with low self-control level;The mean value of the emotional process is higher than the task decision process.(4)It can be seen from the LF/HF results that the college students with high self-control level under positive emotional state have lower mean value than the self-control level college tennis players,and the negative emotions show opposite differences;The high mean value is higher than the self-control level;the mean value of the decision process is significantly higher than the mean value in the emotional process.Through the results of the study,it is found that emotion and self-control have a significant impact on the sports decisions of college tennis players,in which the decision-making time of tennis players in the positive emotional state is shorter,while in the negative emotional state,the negative emotional state has a negative effect on the sports decision-making of college tennis players.However,there was no significant difference in the correct rate between the two emotional states.The decision quality of tennis players with high self-control ability is obviously better than that of tennis players with low self-control ability. |
