Research On Cognitive Characteristics Of Visual Information About Tae Kwon Do Real And Fake Actions

Tae Kwon Do has been carrying out widely in our country while more and more people are beginning to pay attention to this sport and engage in it. It is a kind of combat sports which has high ornamental value and requires wits and courage. Tae Kwon Do athletes need a long and hard training and competition in order to win the game and make the final victory. Besides,they have to constantly improve their capacity and technicality and tactic,keep challenging the limitations of their own physicality and mentality. It is important to choose the appropriate methods and starting point for analyzing the physiological and psychological characteristics profoundly,discovering the characteristics of motion,and improving the training level. When playing the Tae Kwon Do,the athletes are constantly heated by opponents. In the Tae Kwon Do competition,the athletes continue action by the opponent's heated confrontation,attack and defense conversion changing and it is easy to lose the attack chance. If the athletes want to win,they have to capture information more effectively than competitors,to determine more accurately,to response more timely,the action more quickly in attack,defense,fight back,and fight back against the ever-changing process. What is effective information; information is measured accurately or not is an important indicator of high level Tae Kwon Do athletes. Accuracy of predictive information is a concrete manifestation of the important indicator. While Tae Kwon Do has its distinctive features,there are few scholars in the movement to study cognitive features of visual information,not to mention to predict the Tae Kwon Do true and false from the visual information. Therefore,in the study,take the Tae Kwon Do athletes from Suzhou; Jiangsu Province as the survey targets,the article surveys Tae Kwon Do genuine action to investigate the characteristics of perception of visual information.In this paper,the author collates the information obtained from Suzhou City,Jiangsu Province 18 videos Tae Kwon Do athletes,the results show that: (1)The correct percentage of the video Tae Kwon Do athletes to judge all genuine action is not very high,only 62.59%,meaning that nearly half of the video is basically wrong judgments.(2)The correct judging number is unevenly distributed,some of the videos are to determine the correct number of 5 or fewer,and in some videos the number of people made the right judgments is 16 or more.(3) Discriminated precisions of male and female Tae Kwon Do athletes of three sports levels,three years'trainings and three types'competition experiences Tae Kwon Do on correct actions are higher than those on false actions; male athletes who owns 5 and more than 5 years of training experiences and 6 and more than 6 times competitions and 6 times the athletes both show significant differences on these two indexes; while women athletes who are at the national level one,national level two and under national level two,participate in Tae Kwon Do training for 2 years ,less than 2 years and 3 or 4 years and have 3 times,less than 3 times and 4 or 5 times'competition experiences do not indicate differences on these two indexes significantly .(4)Male athletes'holistic precisions,real holistic precisions and real precisions are higher than female athletes,while false holistic precisions,false precisions and total scores were all lower than female athletes'; master athletes'six indexes of holistic precisions,real holistic precisions,real precisions false holistic precisions,false precisions and total scores were significantly higher than those of national level two and under national level two athletes; six indexes of athletes who participate in Tae Kwon Do training for 5 years and more than 5 years are higher than ones who participate in Tae Kwon Do training for 2 years and less than 2 years,and furthermore holistic precisions,real holistic precisions and real precisions show clear advantages; all indexes of athletes who participate in Tae Kwon Do games for 6 times and more than 6 times are higher than ones who participate in Tae Kwon Do training for 3 times and less than 3 times.(5)All athletes'sports levels,the training periods,the game experiences and whole correct numbers,real positive number amounts ,false positive number amounts and total scores of videos which are used to judge real or fake actions are related ,but correlation degrees between each other vary.(6)When athletes determine distinguish real or fake actions,their gazing positions concentrate on perspectives of parts of the whole body (shoulder,arm,waist,foot),actual distance and the body barycenter's movement range,rhythm and line change.(7)Because of filming angle and the limitations of field match watching,players who watch videos generally do not see player's eyes in specified videos. As a result,it is not reliable to forecast real or fake actions on the basis of changes in opponents'eyesight. But through interviews,it is learned that some athletes do predict real or fake actions on the basis of eyesight information in competitions.
