Study Of The Cognitive Processing Characteristics Of Volleyball Players In Judge Service Placement

This paper takes Changchun Normal University Sports Institute 24 male volleyball players as subjects,including 12 two athletes and 12 volleyball professional students,the subjects were male,the movement situation of volleyball players in the judgment serve as stimulus materials,experimental research on cognitive processing characteristics of different sports level the volleyball players,while recording and analysis of different levels of sports Volleyball Athletes' cognitive processing characteristics and analysis of different ways of serving eye tracking in judging the service placement time.The results showed:(1)Different levels of volleyball players in judging the serve,to serve different way to predict the cognitive processing characteristics of different parts,mainly watching elite athletes serve the judgment of shoulder,arm,wrist and waist and ordinary athletes on the ball and the torso and head are watching distribution,and the proportion of the total fixation distribution 40%.(2)the higher the athlete's athletic level is,the faster the reaction speed is,the more accurate the judge is.All athletes have the lowest accuracy and the longest response time for the jump service.The prediction accuracy of the float ball is the highest,and the response time is the shortest,and the accuracy of the prediction and the reaction time between the jump serve and the jump ball.(3)The cognitive processing model for elite athletes in the judgment of serving placement than the students more reasonable,in the judgment of jump serving,excellent athletes found way to serve the different cognitive processing mode reasonable in the pre.Elite athletes jump serve placement in judgment with saccade distance is long,short duration,fixation frequency,fixation point connected into a spindle shaped cognitive processing mode.Suggestion: When training the cognitive processing in judging the service point of the volleyball players,the main points of attention can be placed on the shoulder,arm,wrist,waist and so on,and the main parts of the information source are trained.But the athletes sentenced the cognitive ability in pre service placement research should focus on the speed and accuracy of reaction for the athletes,and athletes on the visual search ability research should choose sports situation more comprehensive judgment,are not a single choice of hair ball,through the discussion of athletes in the judgment of cognitive processing the characteristics of service placement tasks,to a certain extent reflects the superiority of the cognitive processing of elite athletes,but after the study can be used by other cognitive processing advantages of sport scene combination to further reveal the excellent sports staff.
