【摘要】：研究目的:對面孔有效的識別是人們社會生活中一項重要的社會認知功能,面孔所傳達的信息在人類社會生活中扮演著一個非常關鍵的角色,不但能幫助人們獲得重要的信息,而且通過促進人與人之間交流溝通,實現(xiàn)適應社會生活的目的�，F(xiàn)如今ERP技術已經應用于認知神經科學方面,大腦的認知功能和運動的關系之間的研究較為普遍。許多學者經過大量的研究已經發(fā)現(xiàn),參加多種不同形式的運動能促進大腦的靈活性,使大腦的效率顯著提高,最終會促進大腦的認知功能。本文主要采用ERP技術,對三種不同的面孔圖片進行識別任務,探討集體項目中隔網類(排球)專選學生和非隔網類(籃球)專選學生面孔識別ERP中N170波幅與潛伏期的差異,以期發(fā)現(xiàn)在面孔加工中認知能力的差異,為體育運動在認知神經科學領域的發(fā)展提供更好的訓練發(fā)展方向。研究對象和方法:本文選擇了山東師范大學體育學院隔網類排球專選學生和非隔網類籃球專選學生,采用人口統(tǒng)計學特征,篩選出符合要求的47人作為研究對象,其中排球組(n=22)、籃球組(n=25)。本論文用到的最重要的研究方法是實驗法,并借以文獻資料法,數(shù)理統(tǒng)計法加以輔助,對選取的47名受試者進行事件相關電位N170指標記錄與分析,分析用到的儀器是德國生產的Brain Vision Analyzer儀器,并做好數(shù)據(jù)的保存工作。實驗完畢后所得到的數(shù)據(jù)包括行為學數(shù)據(jù)和ERP數(shù)據(jù)統(tǒng)計用SPSS17.0 for Windows,組間差異和組內差異顯著性檢驗采用獨立樣本T檢驗,用p0.05表示顯著差異,極p0.001表示極顯著差異,結果均已?X?SD表示。研究結果:(1)籃球組的反應快于排球組(P0.05),籃球組和排球組間正確操作率無顯著性差異(P0.05)。(2)在三種不同面孔圖片的刺激下,排球組和籃球組專選學生N170波幅存在差異,潛伏期存在差異,波幅的差異表現(xiàn)較為明顯。(3)與隔網組排球專選學生相比,在識別平靜面孔圖片和高興面孔圖片時,非隔網組籃球專選學生的N170波幅要大,潛伏期長。隔網類運動與非隔網類運動之間存在差異。結論:隔網類運動項目與非隔網類運動項目作為不同項群類別對事件相關電位N170的影響有一定的差異,總的來說非隔網類運動員在沒有隔網的運動場上不僅要識別出隊友更要識別出對方隊員,所以投入分配的注意力資源會更多,認知加工過程中神經活動被激活的水平高,幫助運動員快速的做出判斷。
[Abstract]:Objective: to recognize faces effectively is an important social cognitive function in people's social life. The information conveyed by faces plays a very important role in human social life, which can not only help people to obtain important information. And to achieve the purpose of adapting to social life by promoting communication and communication between people. Nowadays, ERP technology has been applied to cognitive neuroscience. The relationship between the cognitive function of the brain and movement is more common. Many researchers have found that taking part in many different forms of exercise can promote the flexibility of the brain and significantly improve the efficiency of the brain. This paper mainly uses ERP technology to recognize three different face images. In order to find out the difference of cognitive ability in face processing, the difference of N170 amplitude and latent period in face recognition ERP between students with net partition (volleyball) and non-netting (basketball) was discussed in order to find out the difference of cognitive ability in face processing. The research object and method: this paper chooses the students of the volleyball of the separated net and the basketball of the non-netting of Shandong normal University, to provide a better training direction for the development of sports in the field of cognitive neuroscience, and the research object and the method are as follows: the students of the college of physical education of Shandong normal University are selected as students. According to the demographic characteristics, 47 people who meet the requirements were selected as the research objects, among which the volleyball group and the basketball group were selected. The most important research method used in this paper is the experimental method, which is assisted by the method of literature data and mathematical statistics. The event-related potential N170 index was recorded and analyzed in 47 subjects. The instrument used in the analysis was the Brain Vision Analyzer instrument made in Germany. At the end of the experiment, the data including behavioral data and ERP data were collected by SPSS17.0 for Windows. The significant test of inter-group and intra-group differences was performed by independent sample T test, and the significant difference was expressed by p0.05. P0.001 indicates very significant difference, the results have been? X? The results showed that the response of basketball group was faster than that of volleyball group (P 0.05). There was no significant difference in correct operation rate between basketball group and volleyball group. There was a difference in latency, and the difference of amplitude was more obvious.) compared with the students in the separated group of volleyball majors, the N170 amplitude of the non-net-separated basketball students was larger than that of the students who chose to recognize the calm faces and the happy faces. The latent period is long. There is a difference between the spacer movement and the non-spacer movement. Conclusion: there are some differences in the influence of the event related potential N170 between the spacer sports and the non-spacer sports. Generally speaking, non-spacer athletes should not only identify their teammates but also the other team members in the sports field without the spacers, so they will devote more attention resources and have a higher level of activation of neural activity during cognitive processing. Help athletes make quick judgments.
