視覺搜索對羽毛球反手搓推勾技術(shù)預(yù)判的影響-執(zhí)行功能的調(diào)節(jié)作用
[Abstract]:Badminton forefield technology is delicate and changeable, the movement differentiation is small, the consistency is strong, outstanding manifests in the backhand rub push hook technique and so on. Only if badminton players have good visual search ability can they make quick and effective judgment and decision with main clues in a limited time. This study starts with the technical characteristics of backhand rubbing and ticking in front of badminton, draws lessons from cognitive psychology research paradigm and experimental methods, and adopts a self-designed badminton pre-judgment test system. This paper tries to find out the influence of different parts of body information search on badminton players' prediction and the function of executive function. Experiment 1 used 2 (level of movement) 脳 5 (shaded part) group design, using space shelter method to cover different parts of the athlete's body, to explore the influence of different parts on athletes' pre-judgment. 40 participants participated in the experiment. In the novice group, there were 20 athletes with average exercise life of 1.32 鹵0.50 years, and the visual acuity and corrected visual acuity were normal, and 20 expert athletes, national second-class athletes, average exercise life of 6.63 鹵1.17 years, visual acuity and corrected visual acuity were normal. The experimental results show that the sheltering beat and arm have a significant effect on the accuracy of the athletes' pre-judgment, while the shading of the head and the lower body have no significant effect on the accuracy of the athletes' pre-judgment. In addition, the accuracy of prediction in different sheltered conditions was significantly higher than that in the novice group, but there was no significant difference in response time between the two groups. In experiment 2, the masking position and executive function (refresh, transformation, inhibition) were regarded as independent variables, and the influence of masking site and executive function (refresh, transformation, inhibition) on athletes' pre-judgment was discussed. 30 participants participated in the experiment. The average sports life of national second-level athletes was 5.58 鹵0.62 years. Normal visual acuity and corrected vision without color blindness. The experimental results show that the executive function refresh subcomponent can positively predict the prediction accuracy, the higher the refresh function is, the more accurate the prediction is, while the conversion and suppression subcomponents have no significant effect on the prediction accuracy. Although there was no significant difference among the three sub-components of executive function (refresh, transformation, inhibition), the prejudgment of high executive function group showed a tendency to be faster than that of low executive function group. The conclusions of this study are as follows: the racquet face and arm are the two key parts of the backhand push and hook technique, and the executive function refresh subcomponent plays a regulating role in the influence of the shading on the athlete's advance judgment. The higher the predictive accuracy of the high refresh group was significantly higher than the low refresh group, the opposite was observed in the sheltered beat.
