A Study On The Eye Movement Of Women 's Saber Athletes' Decision - Making

Recently, decision-making in a lot of sports movement of the degree of task plays a vital role, sport psychologists have decision-making research into one of the more important concerns. In cognitive theory and behavioral skill learning and control under the premise of theory as the foundation, combined with the station on the basis of predecessors’ research results, to explore the effects of the sports level of anticipation to compare different sports level of female athletes of the accuracy of the timing differences between athletes with swords. To ensure that can make high strategic information in sports athletes use can let us more systematic and comprehensive to understand and grasp, to provide some help and reference, and of his sword and fencing training and competition to provide more valuable practical role and positive significance.Experiments using 2(motion level) x 2(Sports scenario) of the mixed experimental design.The sport level variables were divided into: excellent horizontal group and general horizontal group, which were from Tianjin City fencing team. The level of outstanding group and the general level of group sabreurs each 6 people. The independent situational(direct attack) and complex scenario(defensive counter attack) are the independent variables of the sport scene.. Dependent variable is athletes decision-making in the timing of the attack speed and judging by opponents of position accuracy and players’ visual search first fixation, fixation, fixation duration. Subjects using eye tracking system(model: Germany SMI eye movement instrument) on each segment of the dynamic play the sports situational video materials in a time to attack to make decisions, in determining the sword of that a moment, quickly press the response key and in a subsequent questionnaire answer to stab the opponent’s position.Analysis of the variance of the data, and the other data for the corresponding description and analysis. Draw the following conclusions:1, simple or complex movement scenarios. The difference of the best time of the excellent horizontal group was significantly lower than that in the general horizontal group, and the reaction time was closer to the right time. The better the opportunity decision of the excellent group was better than the time of the players.2, simple or complex sports situation, the athletes of the excellent level group is far higher than the correct rate of the attack decision-making point of the general level group.3, simple and complex sports situation, the excellent level of the players in the first note between the number of viewpoints appear is much higher than the general level of athletes. In the general horizontal group, the first injection viewpoint is more concentrated in the opponent’s head and hand.. Note: the first injection viewpoint of the excellent level group concentrates on the judgment of the distance between the players, while the general horizontal group is more concerned with the local parts of the opponent’s body.4, a simple video and complex video, the fixations of the excellent level subjects are concentrated in the torso of the opponent’s body, the general level of group of athletes fixation point more dispersed in the opponent’s hand, head, foot local position. Note: the focus of the excellent level group is more concentrated on the opponent’s overall form, while the general horizontal group is more concerned with the local parts of the opponent’s body.5, the sport grade in athletes looking head, feet, hands, torso four body position fixation time there is main effect, moving scene in athletes looking head, feet, hands, torso four body position fixation time there was no main effect. The fixation duration of the superior horizontal group was longer than that of the general horizontal group, and the fixation time of the head and foot was shorter than that of the common level.. Description: level outstanding group of subjects in the experiment will be watching most of the time stay in the opponent’s torso to the trend of overall observation opponent, better collection and each other to pass on information search, in the decision-making process can make level of outstanding group of subjects with more reference to the factors, the accuracy of the decision have great help.
