ERP Research On Basketball Decision-making Characteristics Under Different Emotional States

With the development of sports and the continuous improvement of competitive level,the influence of emotion on decision-making in sports is increasingly concerned by scholars in relevant sports field.The changes of emotion will affect our cognitive level,brain processing and concentration,which have influence on our decision-making and level of sport.The event-related potential which acts as evoked potential provides us a way to observe the changes of brain potential.In recent years,more and more scholars have paid their attention to the studies related to psychology in PE field,of which also improve the instrument of ERP applied in these related researches,meanwhile the interviews which focus on the affection of our emotion to decision-making are less.Concerning all mentioned above,this study will analyze the change of event-related potential in our emotion and then the analysis of our decision-making will be given.Taking the basketball sports as an example,we set the control of emotion as the between-group variable,meanwhile set decision-making type as the inter-group variable,and the experiment is conducted by the method of psychology study.During this study,the start of emotion and the changes of the decision will be considered and the change of event-related potential and the decision-making will be analyzed under this condition.The participants are all male students at sport college in China.Laboratory USES is conducted by the basketball decision image system which are carried out under a good laboratory experiment environment,participants finish all the tasked with the help of computer and the data will be collected by computer as well.The experiment consists of a preliminary experiments and a formal experiment.The selection of emotional materials and the selected images which will be verified by statistical methods are included in the experiment I,which has a good validity;And then the experiment II includes the development of the basketball decision system and the selection of pictures,while the selection,processing and continuous improvement of basketball pictures are also involved in this part.The formal experiments included theexperimental design of emotion(2)x decision(2)x brain region(3),and repeated measurement variance analysis for the obtained experimental results.The conclusion are given as follows: first of all,the result of accuracy and reaction time,the two emotions(positive emotion,negative emotion)and two kinds of decision-making(intuitive decision making,cognitive decision),exist significant differences in the interaction,which means that the level of decision-making will be affected by the influence of different emotions.Secondly,observing the data of behavior,the accuracy and reaction time of cognitive and intuitive decision-making in positive emotion are higher than ones in negative emotions,which illustrates that the positive emotions have positive affection on us.Thirdly,during the analysis of ERP data data,we selected P100,P200 and N100 components to observe the brain potentials that caused the change in decision-making.For N100 component,repetitive measure analysis of variance shows that different emotions category exists significant differences,which means that the decisions are influenced by emotion and incubation period of occipital area is longer than frontal area and roof area.What's more,there exists significant differences in the location and decision-making of the peak brain region,which means the incubation period of the occipital area is longer than the frontal area and the top zone.Finally,there is no significant difference in the latent period in the N2 component.In the measurement of the crest,the main effect of the position is significant,and the crest of the frontal area reaches the maximum.Above all,this study draw the conclusion that different emotions can have different effects on our decision-making behaviors.
