| No matter what the project is in the course of the competition,the level of literacy and ability of the referees influences the progress of the game.In the tennis game,the fair determination of the referees plays a crucial role in the entire game.In high-intensity,fast-paced,long-term gaze games,referees are prone to visual fatigue,and even pay attention to the moment.In this case,if there is a key ball,many experienced high-level referees can quickly use intuition.Sex decisions are made with penalties and accuracy is high,and some novice referees are more jerky.The purpose of this study is to analyze the decision-making differences between novice and expert tennis referees through behavioral experiments and ERP techniques in order to find out the difference between decision-making by novices and expert judges.In this study,11 expert tennis referees and 11 novice referees were selected for the study,and a novice-expert research paradigm was adopted.The high-speed tennis ball and shots were used as experimental video materials.The E-Prime program was used.ERP conducts experiments to study the differences between the cognitive and intuition decisions of tennis referees from behavioral data and ERP data,so as to learn about the decision-making advantages of high-level tennis referees,and to add artificial walking disturbances during the course of the experiment.Verify the reform of the new regulations.Through experiments,the analysis results are as follows:(1)Intuitive decision-making has occurred in both novice and expert group subjects,and there has been a significant difference in their intuitive decision-making.(2)Novice group participants had a slower response to the video presentation decision-making than either expert group in the case of interference or without interference.In the context of interference,the response time of the expert group participants was obvious.It is better than the reaction time of the novice group participants,and the difference between the response time and the undisturbed reaction time is relatively small,which fully reflects the high concentration of experts and the stronger ability of anti-interference.(3)From the intuitive decision making on the accuracy of also show whether there is interference in the case or under the condition of no interference of expert group of intuitive decision making is not one hundred percent correct,but compared to the novice group were higher than their intuition decision accuracy.In the case of interference,referees are more focused,so their accuracy can be improved when there is an interference.Novice group of participants and the panel participants in the presence of interference of intuitive decision making of the time difference is not big and it proves the new rules reform's feasibility because the audience's move has little effect to the referee.(4)In the absence of interference,the latent period of P1 components induced by the frontal and central regions of the cerebral cortex in the expert group were significantly shorter than that of the novice group.In the case of interference,the expert group was tested in the cerebral cortex.The latency of P1 components induced in the frontal zone,central zone,top zone,and occipital zone was significantly shorter than that of the novice group.This shows that when the stimulation occurs,the attention of the panelists is more meticulous,and the judgment of the direction of the ball is more accurate.It is more conducive to make intuitive decisions.(5)In the absence of interference,the incubation period of the N1 component induced by the frontal region,the central apex region,the top region,and the occipital region of the cerebral cortex in the expert group was significantly shorter than that of the novice group;in the case of interference,The N1 components induced in the frontal,central,central apex,and occipital regions of the cerebral cortex in the expert group were significantly shorter than those in the novice group,indicating that the expert group had a shorter mental process after the stimulus.The processing of decision tasks is faster.(6)In the absence of interference,the N2 component induced by the central apex of the cerebral cortex in the expert group was significantly shorter than that of the novice group;in the case of interference,the expert group was tested for the frontal cortex The N2 components induced in the anterior area of the brain,the apical area and the occipital area were significantly shorter than those of the novice group,indicating that the expert group's attention to visual stimuli was faster and the decision-making response was more important.(7)In the absence of interference,the incubation period of the P3 a component induced by the frontal area and the anterior area of the cerebral cortex in the expert group was significantly shorter than that of the novice group;in the case of interference,the expert group was tested brain The latent period of P3 a components induced by the frontal area of the cortex,the anterior area of the anterior area of the brain,and the occipital area was significantly shorter than that of the novice group.This can show that the stimulation of the expert group participants is more likely to be awakened,and the expert group's intuitive decision-making response is better than the novice group participants.(8)In the absence of interference,the incubation period of the P3 b component induced by the central area of the cerebral cortex of the expert group was significantly shorter than that of the novice group;in the case of interference,the expert group was tested in the central area of the cerebral cortex.The incubation period of P3 b components induced by the top and occipital regions was significantly shorter than that of the novice group subjects.It shows that the responses of the expert group participants to the target stimulus are more rapid,and the intuitive decision-making advantage is more obvious.(9)From the overall amplitude of P1,N1,N2,P3 a,and P3 b components induced from different regions of the cerebral cortex,the novice group and the expert group subjects have significant amplitudes of ERP in the presence or absence of interference.Differences,novice group participants themselves have significant differences in the amplitude of the conditions of whether there is interference,the expert group participants have no significant difference in the amplitude of the conditions of whether there is interference,which shows that the experts in the group of experts to stimulate the emergence of decision-making The anti-interference ability of the time is better than that of the novice group.The reaction of decision-making and the speed of information analysis are more efficient and rapid. |
