【摘要】：研究目的:对面孔有效的识别是人们社会生活中一项重要的社会认知功能,面孔所传达的信息在人类社会生活中扮演着一个非常关键的角色,不但能帮助人们获得重要的信息,而且通过促进人与人之间交流沟通,实现适应社会生活的目的。现如今ERP技术已经应用于认知神经科学方面,大脑的认知功能和运动的关系之间的研究较为普遍。许多学者经过大量的研究已经发现,参加多种不同形式的运动能促进大脑的灵活性,使大脑的效率显著提高,最终会促进大脑的认知功能。本文主要采用ERP技术,对三种不同的面孔图片进行识别任务,探讨集体项目中隔网类(排球)专选学生和非隔网类(篮球)专选学生面孔识别ERP中N170波幅与潜伏期的差异,以期发现在面孔加工中认知能力的差异,为体育运动在认知神经科学领域的发展提供更好的训练发展方向。研究对象和方法:本文选择了山东师范大学体育学院隔网类排球专选学生和非隔网类篮球专选学生,采用人口统计学特征,筛选出符合要求的47人作为研究对象,其中排球组(n=22)、篮球组(n=25)。本论文用到的最重要的研究方法是实验法,并借以文献资料法,数理统计法加以辅助,对选取的47名受试者进行事件相关电位N170指标记录与分析,分析用到的仪器是德国生产的Brain Vision Analyzer仪器,并做好数据的保存工作。实验完毕后所得到的数据包括行为学数据和ERP数据统计用SPSS17.0 for Windows,组间差异和组内差异显著性检验采用独立样本T检验,用p0.05表示显著差异,极p0.001表示极显著差异,结果均已?X?SD表示。研究结果:(1)篮球组的反应快于排球组(P0.05),篮球组和排球组间正确操作率无显著性差异(P0.05)。(2)在三种不同面孔图片的刺激下,排球组和篮球组专选学生N170波幅存在差异,潜伏期存在差异,波幅的差异表现较为明显。(3)与隔网组排球专选学生相比,在识别平静面孔图片和高兴面孔图片时,非隔网组篮球专选学生的N170波幅要大,潜伏期长。隔网类运动与非隔网类运动之间存在差异。结论:隔网类运动项目与非隔网类运动项目作为不同项群类别对事件相关电位N170的影响有一定的差异,总的来说非隔网类运动员在没有隔网的运动场上不仅要识别出队友更要识别出对方队员,所以投入分配的注意力资源会更多,认知加工过程中神经活动被激活的水平高,帮助运动员快速的做出判断。
[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.
