The Influence Of Self Depletion,Moral Identity And Emotional Regulation Strategies Of Sports College Students On Sports Moral Judgment

Previous studies on moral psychology paid more attention to general situational morality and less attention to the characteristics of moral judgment in sports context.Therefore,based on behavioral evidence,this study explores the influence of ego depletion and moral identity on sports moral judgment of college students majoring in physical education;Based on behavioral and cognitive neuroscience evidence,this paper explores the processing characteristics and mechanism of ego depletion and emotion regulation strategies in sports moral judgment of college students majoring in physical education.In experiment one,80 college students majoring in physical education were randomly selected as experimental subjects,and a two-factor inter-subject design of 2（ego depletion:high ego depletion or low ego depletion）×2（moral identity: pried or not pried）was adopted.The independent variable was ego depletion and moral identity,and the dependent variable was sports moral judgment score.The results show that the interaction between ego depletion and moral identity is significant in the score of sports moral behavior judgment.In the moral identity priming group,there was no significant difference between the high ego depletion group and the low ego depletion group;In the unprimed group,the moral judgment score of the low ego depletion group was significantly higher than that of the high ego depletion group.In experiment two,61 college students majoring in physical education were randomly selected as experimental subjects,and a three-factor mixed design of 2（ego depletion: ego depletion,low ego depletion）× 2（emotion regulation strategies: cognitive reappraisal,expression suppression）× 2（moral factor: moral,moral violation）was adopted.Ego depletion and emotion regulation strategies were intergroup variables,moral factor was intra-group variable,and the dependent variable was the average amplitude of N1,P2,N2 and LPC components in the process of sports moral judgment.In sports moral judgment accuracy rate,the results showed that there was no significant difference between cognitive reappraisal strategy and expression suppression strategy under high ego depletion.In the low ego depletion state,expression suppression strategy can alleviate the aftereffect of ego depletion and improve moral judgment level more than cognitive reappraisal strategy.In ERP,the LPC amplitude induced by high ego depletion-cognitive reappraisal group was larger than that of low ego depletion-cognitive reappraisal group,and the LPC amplitude induced by low ego ego depletion-expression suppression group was larger than that of low ego depletion-expression suppression group.The following conclusions can be drawn :（1）ego depletion and moral identity affect the level of sports moral judgment of college students majoring in physical education;（2）Ego depletion,emotional regulation strategies and moral factors affect the judgment level of sports ethics of college students majoring in physical education;（3）Priming moral identity and adopting emotion regulation strategy can alleviate the effect of ego depletion on sports moral judgment to a certain extent.
