The Differences Of Decision Making And Visual Search Features Between Different Level Basketball Referees

In terms of confrontational sports, because the changing conditions, the referee in thedecision process, the main visual function, through the eyes of observation, conveyinformation and objective judgment space across the region. Most players are running athigh speed or crowded happen foul or violation behavior, after the actions happen, face areferee mainly by visual sensation to the brain center, after a quick judgment and brewingquickly make the right response, in the process of game, ask referees on-the-spot decisiontime is short, high accuracy. Because the field athletes of the uncertainty of the fast movingand moving path, must face the referee in the case of an emergency situation change ishighly predictive of face. Is based on the part or the previous information to an actionunder the athletes to make some degree of prediction, to win time for decision-making, soas to make the right judgment. Therefore, judges should possess broad field of vision,extremely good anticipation ability and rapid judgment, could do with everything takeninto consideration, in a rapidly changing game ball to two or morethings. To makeobjective to match the right decision. This study aims to use eye movement technology,foul play video in different time points, cognitive tasks at different level of basketballreferees in different levels on the difference of visual search. Experiment randomlyselected40participants, including members of professional level for the universitybasketball referees (N=20), amateur photographers for secondary basketball referees (N=20), and USES the visual search paradigm, record it and eye movement information.Experiments at different levels of basketball referees in foul in different time point searchthe differences in the visual search task, and the interpretation of the eye patterns arediscussed. Experiment task is asked to be tried in foul play video in different time points,determine the nature of the foul, and foul. Comprehensive experimental results anddiscussions, one of the main conclusions of this study are as follows::1, video playback,the high level of referees can foul in action or suspected foul action before physical contactand contact to make the right judgment, and the accuracy is higher, the excellent basketballreferees also has stronger situation forecast ability.2. For a foul situation related on offenseand defense, the position of the ball, and defence and players game development area,different level of referees attention to significant differences in time and sequence. Highlevels of referees has obvious advantages of visual search.
