| Objective: Although the research on narcissism and disgust in psychology has been studied for a long time,there are still many unknown problems.From the perspective of social personality field,explore the connection between pathological narcissism and disgust of college students,and combine event-related potential technology to understand The physiological mechanism of aversion of pathological narcissistic college students.Methods:The pathological narcissism scale and the Chinese version of the disgust sensitivity scale were used to measure 515 college students.According to the total scores of the pathological narcissism scale,the first 27% and the second 27% were selected as high and low groups.Divide into groups and perform a test of disgust vocabulary part of speech and a test of word disgust to meet the requirements,and collect EEG data at the same time.A total of 44 subjects participated in the aversive vocabulary judgment test.After excluding 4 subjects with serious artifacts and behavioral accuracy less than 80%,there are 40 remaining subjects.The average age of the low group is 18.85±1.35,8 boys and girls There were 12 people with an average PNI score of 56.40±19.42;the average age of the senior group was 18.75±1.33,with 8boys and 12 girls,with an average PNI score of 160.45±15.36.Results: Questionnaire results:The total score of the aversion sensitivity scale was significantly positively correlated with the total score of the pathological narcissism scale(r = 0.420,P < 0.01).The total score of pathological narcissism was related to core aversion,animal-related aversion and pollution aversion.Significantly positive correlation(r = 0.253,P < 0.01;r = 0.321,P < 0.01;r = 0.290,P < 0.01),the total score of aversion sensitivity and the two factors of narcissistic exaggeration and narcissistic vulnerability are also All were significantly positively correlated(r = 0.427,P < 0.01;r= 0.345,P < 0.01).Behavioral results: he independent sample t test was used to analyze the correct rate,reaction time,aversion degree judgment,and degree judgment reaction time of the three types of words.it can be seen that the high and low groupings do not exist in the correct rate of part of speech judgment and reaction time.Significant difference,the high group’s response to moral disgust and neutral words in the judgment of the degree of disgust was significantly higher than that of the low group(t = 2.019,P< 0.05;t = 2.392,P < 0.05),and there was no significant difference in the degree of disgust.Using repeated measures analysis of variance,the results show that the main effect of the part of speech on the correct rate of vocabulary judgment is significant[F(1.54,58.44)= 6.209,P<0.01].The post-event analysis shows that there is a significant difference in the correct rate: Moral disgusting words <physical disgusting words,neutral words < physical disgusting words;other effects are not significant.The main effect of upper part of speech in response to vocabulary judgment is significant[F(1.47,55.86)= 15.875,P<0.01].Post-mortem analysis shows that there are significant differences in response time: neutral words> physiological aversion words,Moral disgusting words > Physiological disgusting words;other effects are not significant.The main effect of the upper part of speech when judging the degree of lexical aversion is significant [F(1.39,52.80)= 24.178,P < 0.01].The post-hoc analysis shows that there is a significant difference between the two in the reaction:physiological aversion words > neutral words,moral aversion words > neutral words;the main effect of the group is significantly marginal [F(1,38)= 3.975,P = 0.053],simple effect analysis shows that: in moral aversion words The response time of the high group and the neutral word is greater than the low group,and there is no difference between the two in the physiological aversion word;the interaction effect between the part of speech type and the group is not significant.The main effect of part of speech on the judgment of the degree of lexical aversion is significant [F(1.72,65.44)= 803.359,P < 0.01].The post-mortem analysis shows that the scores are significantly different between the three types of words: moral aversion Words > Physiologically disgusting words > neutral words;the other effects are not significant.ERP results: The main effect of N1 component group was significant [F(1,38)= 4.569,P < 0.05],and the mean amplitude of high group was smaller than that of low group.The main effect of the type of verbal stimulus was significant [F(2,76)= 3.985,P < 0.05].Postmortem examination showed that the average amplitude of moral disgust words was greater than that of neutral words.The interaction between speech types and groups was critical and significant [F(2,76)= 2.911,P = 0.067].Simple effect analysis showed that the mean amplitude of moral disgust in high pathological narcissism group was greater than that in physical disgust,while the mean amplitude of physical disgust and moral disgust in low pathological narcissism group was not different.The main effect of the electrode points was significant [F(8,304)= 15.600,P < 0.001].The interaction between the part of speech types and the electrode points was not significant.The main effects of P2,N2 and LPC were not significant in the high and low groups.Conclusion:Pathological narcissism and disgust sensitivity of college students are positively correlated;the pathological narcissism high group is only significantly higher than the low group in the response time of the moral aversion word;the pathological narcissism high group and the low group are in the physiological aversion word and the moral aversion word There was no significant difference in the amplitude of induced P2,LPC,and N2,while the N1 amplitude of the low group was significantly greater than that of the high group,and the amplitude of moral disgust in the high group was significantly higher than that of physiological aversion. |
