Study On Eye Movement And ERP Characteristics Of Penalty Defensive Football Goalkeeper Perceptual Anticipation

In football sports,football goalkeeper defensive penalties often determines the competition,in order to successfully defend a penalty to win the game,goalkeeper first predicted to kick direction kicker,and then make a decision after action.According to the characteristics of soccer penalty in short time,fast ball,football goalkeeper requirements before making a decision to act,the visual search to the key information or information in advance.At present,there are few researches on the specific differences in visual search and the electrophysiological aspects in the process of information processing in the process of defending the penalty.This study is guided by the theory of experience sports experts cognitive advantages said,based on information processing theory,the expert novice paradigm,with time blocking the way to stimulate the video,7 men athletes athletes were selected from the expert group of Shandong Sports Institute has two national level football goalkeeper;novice group 10 never the contact but understand football theoretical knowledge of the Shandong Sports Institute students,with the help of eye movement and event-related potential synchronization technology,to explore the process of defense penalty movement characteristics and ERP characteristics,try to explore information processing characteristics of defense experts predict the goalkeeper penalty line process.Further enrich the theory of motion perception prediction,and provide scientific basis for the scientific training of football goalkeeper.Based on the experimental results,the following conclusions are drawn:1 in the process of defending the penalty,the excellent football goalkeeper can quickly and accurately predict the behavior characteristics of the football players in different time.2 in the process of defending the penalty,the excellent football goalkeeper looks at the head,the supporting leg and the swing leg of the free throw player,and has a simple and economical scanning path.3 in the process of defending the penalty,the P1 and P300 components reflect the process of the football goalkeeper's visual information processing.4 in the process of defending the penalty,the early use of psychological resources,more time is used to compare and judge,and then ensure the accuracy of the forecast,improve the cognitive processing ability.
