| Research purposes: the effective recognition of face is very important in the social life of the people’s social cognition,the message conveyed from face in plays a critical role in the human social life,through the recognition of face to realize the interpersonal communication,access to important information,in order to better adapt to social life.Now ERP techniques have been applied in the field of cognitive neuroscience,especially in the study of movement and the brain cognitive function.Many previous studies have shown that exercise not only can improve the body health,but more likely to promote the cognitive performance,improve the efficiency of the use of brain function.ERP technology,this article uses three different face images for recognition task,to explore the collective projects Netting sport(volleyball)elective students,and the non-Netting sport(basketball)elective students face recognition of the differences in the N170 amplitude and latency of ERP,in order to find the cognitive differences in face processing,provides a better platform for theory development for sports development in the field of cognitive neuroscience.The research object and methods: selection of shandong normal university sports college volleyball elective students and basketball elective students,and adopt the demographic characteristics,47 people selected to meet the requirements as the research object,the volleyball group(n = 22),the basketball group(n = 25).Paper uses the literature material method,mathematical statistics method,experimental method,etc.The research methodsAnalysis of the instrument used is the German production of Brain Vision Analyzer instrument.On subjects in human movement science laboratory of event related potential N170 indicators for one-time records and analysis.Event related potential uses.Using SPSS17.0 for Windows to statistical data from difference significance test between groups using independent sample T test,p < 0.05 said significant difference,p < 0.001 said significant differences,the results should be expressed in ?X ? SD.The results of the study:(1)Basketball group react faster than the volleyball group(P <0.05).Correct operating rate between basketball and volleyball group there was no significant difference(P > 0.05).(2)In three different face images under the stimulus of volleyball and basketball group specially selected students N170 amplitude differences,the incubation period is different,the amplitude of the differences in performance is more obvious.(3)Compared with volleyball subjects,In identitying calm face image and hapy face image,basketball N170 amplitude is greater than the volleyball group,significantly prolong the incubation period in the volleyball team.Conclusion:Netting sports and non-netting sports as the influence of different category of event related potential N170 has certain difference,in generally,the non-netting athletes are not only to identify the teammates more players to identify each other in the sports field,so there will be more attention resource investment allocation,high levels of neural activity are activated during cognitive processing,to help athletes to respond rapidly. |
