Effect Of Spatial Working Memory Capacity On Visual Search Characteristics Of Basketball Players Under Offensive Decision Task

In the actual sports scene,athletes need to use visual search or selective attention to make offensive predictions,many previous researchers’ experiments have proved that visual search and selective attention will affect the visual space working memory,therefore,this study will introduce the visual space working memory into the study of basketball players’ offensive decision-making,try to explore the impact of visual space working memory capacity on basketball players’ offensive decision-making.The process of athlete visual search will be importantly influenced by the specific cognitive basis and practical experience,and this study explores how instantaneous memory affects athlete visual search from the perspective of spatial working memory.By continuously analyzing the memory characteristics of basketball players’ cognition and decision-making expertise,it enriches the visual search theory basis for the tactical consciousness performance of basketball players,and promotes the development of research in the field of sports perception decision-making.A total of 26 participants were selected to restore the real basketball "2V1" game scene to shoot and produce stimulus materials;the two-way hybrid experimental design of 2 sports levels（expert group,novice group）×2 spatial working memory capacity（high and low）was used;and the experimental data was collected and processed by Dikablis Professional head-mounted eye tracker,D-Lab3.0 and other equipment software,and the conclusions were as follows:（1）The efficiency of a basketball player’s tactical decision-making is influenced by many factors,such as the athlete’s own level of exercise and years,as well as the frequency of their participation in high-level games,and their attention to professional leagues.（2）In the analysis of basketball players’ offensive decisions,compared with the novice group,the expert group has more efficient and reasonable tactical decision-making behavior,and is faster and more accurate in the basketball offensive decision-making process.（3）The spatial working memory capacity has a significant impact on the on-the-spot decision-making of basketball players,mainly manifested in the fact that high-capacity athletes make decisions on the playing field for a long time,and high-capacity basketball players usually use more investment to integrate the resources and information fed back by the game scene in the offensive process,and then process and process to have a global grasp of the environment and situation on the court.The level of exercise affects the rationality of basketball players’ offensive and tactical decisions,which is manifested in the fact that the rationality of tactical decisions of expert group athletes is generally better than that of novice athletes.（4）Basketball players of different capacities have different decisions in the decision-making process.The expert group has few fixation points and a simple and clear fixation path,which can perform key information focus searches,while the novice group has more fixation points and complex fixation paths.
