Study On The Perceptual Specificity Of Badminton Exercise Intervention In Autistic Children

Objective: To explore whether badminton has an intervention effect on the perceptual function of autistic children,so as to provide social reference for the methods of autism intervention,and provide basis and suggestions for further enriching and improving the perceptual specificity of autistic children.Research Methods: In this study,25 children from Changchun,Jilin Province aged 6-16 and 53-66,no intellectual defects and small proportion of sports ability)and 25 normal children aged 6-16 years were control group（normal intelligence,healthy health and normal vision）.Using badminton exercise intervention before and after the two groups of subjects in building blocks test spatial visual ability and in functional near infrared spectroscopy technology（f NIRS）under the monitoring of mosaic graph test two groups field cognitive style ability,and explore the cerebral cortex of the concentration of oxyhemoglobin,and explore the perceptual specificity characteristics of autistic children.The independent sample t test and paired sample t test were used to statistically analyze data before and after the subject experiment.The results: due to the unstable emotional factors in autistic children,there is no fixed normal mode standard;and perceptual specificity is not a unique characteristic of autistic children,the spatial visual ability,field cognitive style,badminton sports level performance and functional NIinfrared technology（f NIRS）system were selected to improve the reliability and test the rigorous experimental technique.1.When response to spatial visualization,The reaction time of the experimental group was shorter relative to the control group,Presa very significant changes,（t=-5.276,p=0.000<0.01）;On the correct total number,The experimental group had more scores compared to the control group,Presenting a significant change（t=2.554,p=0.014<0.05）;In the scoring scores,The experimental group scored higher scores relative to the control group,Presenting a significant change（t=2.114,p=0.040<0.05）;It can be seen from this,After the experiment,the spatial visual ability of the two groups was different.2.On the field of cognitive style score scores,The experimental group had higher scores relative to the control group,Present a significant change（t=2.115,p =0.040<0.05）,During the reaction time,The reaction time of the experimental group was longer relative to the control group,No significant changes;On independence score,The experimental group had higher scores relative to the control group,Presenting a significant change（t=3.430,p=0.009<0.01）;The field-dependent cognitive style score of the experimental group was higher compared to the control group,There were significant changes（t=4.157,p=0.001<0.01）..It can be seen that the mosaic figures showed significant differences in the field cognitive style,field independence style and field independence style scores of the two groups,and the score performance of the field dependence style measurement did not change significantly,because most people rely on the help of the field.3.In the first two groups,the experimental group score was higher than the control group,showing significant changes（t=-4.085,p=0.000 <0.001）;in the far badminton score,the experimental group scored higher than showed significantly（p=0.001 <0.01）;in the long jump score,the experimental group showed significant changes（t=-2.2 56,p=0.029 <0.05）.It can be seen that the research results of the forehand bouncing,badminton throwing and long jump between the two groups showed significant differences.4.Functional near-infrared spectroscopy（f NIRS）system monitors the comparative analysis of oxygenation hemoglobin content in the three subjects of the two groups in the task state.The right occipital lobe area（t=2.178,p=0.037 <0.05）and the left parietal lobe area（t=3.072,P=0.005 <0.001）of the right parietal lobe area（t=-4.440,p=0.000 <0.001）showed significant changes.It can be seen that through the functional near-infrared spectroscopy（f NIRS）system,the two experimental groups have monitored the right parietal area and the left parietal area and the control group of the right parietal area in the experimental group in the task state.Conclusion: 1.Through the badminton exercise intervention,with normal children’s spatial visual ability of perceptual specificity contrast,the test blocks of spatial visual ability reaction time and problem speed showed an obvious advantage,shows that the badminton intervention improved the autistic children spatial visual ability of perceptual specificity.2.After badminton intervention,make a comparative analysis of normal children’s cognitive style,integrate the cognitive style of autistic children,gradually adapt to the dependence of the field from the field independence,and improve the ability of social communication.This shows that the intervention of badminton improved the perceptual specificity of field cognitive style in children with autism.3.After the badminton sports intervention,a comparative analysis of the badminton sports level performance of normal children was made.According to the experimental results,we can find that the badminton training has significantly improved the upper limb strength,motor ability and coordination ability of autistic children.4.With normal children in the functional near infrared spectrum technology（f NIRS）system monitoring task state of different brain area on the degree of oxyhemoglobin change comparative analysis,children with autism after badminton intervention,from unilateral attention to bilateral attention after intervention,badminton can improve autistic children on the degree of brain area,improve the oxyhemoglobin content,accelerate the active brain.5.Through the experimental results,we can conclude that the spatial visualization and cognitive style of autistic children improve the perceptual ability and social communication ability,and the perceptual specificity of autistic children is enhanced through badminton training.
