ERP Research On Sports Students' Recognition Of Pictures Under Different Emotional Conditions

Since Ribot put forward the concept of emotional memory in 1894,it has been widely valued and studied by relevant scholars.It has once been the favorite of psychologists.The ERP event related potential is an important window for the "peep" of human mental mental activity,and it is an economical,precise,accurate and non traumatic technology.In order to better enrich the research theory of emotional memory and understand the mechanism of brain cognitive neurophysiology,this paper uses the ERP event related potential technology and the experimental method of combination of behavior and brain electricity.In the field of sports psychology,it combines psychology with physical education to start the sports under different emotional conditions.The research of picture recognition memory of professional students is innovative.The experimental study of the design group variables is a state of emotion,which is induced by the process of watching emotional pictures.The individual emotional state caused by the stability factor of emotional picture is used as the inter group independent variable,and the type and nature of the picture is the independent variable in the group.The emotional state is divided into two groups: positive emotion group and negative emotion group;picture type is divided into two kinds: sports picture and non sports picture;picture nature is divided into two kinds: the picture and the picture have not been studied.The subjects were 32 male students from the College of physical education of Shandong Normal University,and the experiment was carried out randomly.The experiment was divided into three stages: emotional start stage,learning stage and test stage.Through the German-produced brain Vision Analyzer32,the EEG was recorded and collected the behavioral EEG data produced by the subjects.The experimental results show :There is a certain difference in the correct rate and reaction time between positive group and negative group picture on the behavior data,but it is not significant.There are significant differences in the recognition accuracy and reaction timebetween the image types,whether active group or negative group.The correct rate of recognition of sports pictures is significantly higher than that of non sports pictures,and the recognition reaction of sports pictures is higher than that of non sports pictures,that is,the recognition accuracy of sports pictures is high and the reaction time is long;On the EEG data,the results of the active group and the negative group are in accordance with the results of the behavior,and there is a significant difference between the picture types.On the P300 component,the amplitude of the sports picture is significantly greater than the amplitude of the non sports pictures,and the incubation period of the sports pictures is significantly greater than the latent period produced by the non sports pictures.On the electrode factor,the amplitude < the amplitude < the amplitude < top area of the central region,the amplitude of the central region;the latent period of the frontal area > the latent period of the central region > the latent period of the top area,that is,the top area is the most active;there is a significant difference between the pictures and the pictures that have not been studied in the picture nature,and the pictures have been studied.The amplitude of the raw wave is significantly greater than that of the unstudied picture,and the incubation period of the picture is also greater than the latent period of the unstudied picture,that is,the new and old effects are produced.
