Research On The Eye Movement Characteristics Of Basketball Guard Players In Sports Decision-making Situation

Basketball is an open,confrontational group project.With the rapid development of basketball,modern basketball requires athletes not only to have comprehensive skills and physique,but also to focus on the stability of psychological quality.And powerful.The basketball defender is the core of the entire team.In the sports scene,the decision of the basketball player is p articularly important.Any decision in the course of the game will affect the di-rection of the game.The level of sports decision-making directly affects the l evel of the athlete's skills and tactics.Give effect.Therefore,this study takes s p-orts psychology as the theoretical basis of the study,uses eye tracking as a re-search method and method,and further analyzes the eye movement character isti-cs and decision-making behavior data of different levels of subjects in the pr-ocess of motion decision.The search characteristics,gaze patterns,and decis io-n-making tactics of basketball defenders are expected to sum up the essence of basketball defender sports decisions.This study is based on the basic paradigm of experts-novices.Based onthis,a level group was added.The subjects were all selected from Chengdu University of Physical Education students.There were 30 students in total and were divided into three levels.10 in the high-level group,10 in the general le-vel group and 10 in the low-level group.Two kinds of different offensive mo tion scene maps are presented through the eye tracker,including three kinds oftechnical movements of the basketball defender's movement,transmission,and casting.The participants are allowed to make judgments on the technical actio-ns on the picture,and the eye movement meter will Automatically record the eye movement data of the subjects and the behavioral response data during dec-ision-making.After statistical analysis of experimental data and analysis of pre-vious research results,the following conclusions are drawn:(1)By comparing the eye movement characteristics of high-level,general-l evel,and low-level basketball defenders,it is found that basketball defenders w-ith different levels have different eye movement indicators and other aspects when they look at the situation pictures.(2)High-level athletes are different from general and low-level athletes in the main channels for information acquisition,information processing speed,an d processing efficiency.High-level athletes can optimize and integrate more inf ormation resources in the process of information processing.,improve the proc-essing efficiency of information.(3)In the accuracy and speed of sports decision-making,different levels o--f athletes and scenes with different degrees of difficulty will have an importa nt impact on the effectiveness of decision-making.(4)The difference in decision-making between high-level and general-level and low-level defenders shows that: in the process of sports decision-making,high-level athletes are comprehensive,while general and low-level athletes are analytical.
