Gender differences in the regulation of negative emotions by positive reappraisal and detached reap-praisal in college students
Objective To explore the gender differences and cognitive neural mechanism of positive reappraisal and detached reappraisal strategies in regulating negative emotions in college students.Methods According to the convenient sampling method,40 students in Chengdu Medical College were se-lected as subjects,and the subjects whose scores of self-rating anxiety scale or self-rating depression scale ex-ceeded the critical value and had too many electroencephalogram(EEG)artifacts were excluded.Finally,the experimental data of 17 men and 17 women were included for statistical analysis.All subjects completed the task paradigm of emotion regulation,and their behavior and EEG data under the conditions of positive reap-praisal,detached reappraisal and free viewing were recorded.SPSS 23.0 software was used for the repeated measurement ANOVA.Results(1)Behavioral results:in valence,the interaction between gender and e-motional regulation conditions was significant(F(2,64)=27.475,P＜0.001).Under the condition of free vie-wing,the male's valence score was significantly higher than that of the female((3.94±1.70),(3.25± 1.44)),and the difference was statistically significant(F(1,32)=33.098,P＜0.001).Under the condition of positive reappraisal,the valence score of women was significantly higher than that of men((6.84±1.33),(6.59±1.17)),and the difference was statistically significant(F(1,32)=7.002,P=0.008).Under the con-dition of detached reappraisal,the valence score of women was significantly higher than that of men((5.84± 1.61),(5.43±1.61)),and the difference was statistically significant(F(1,32)=10.942,P=0.001).In a-rousal degree,the main effect of gender was significant(F1,32)=60.745,P＜0.001),and the emotional a-rousal degree of women was significantly higher than that of men((4.27±0.05),(3.69±0.05)).(2)ERP results:in the N200 component,the main effect of sex was significant(F(1,32)=4.253,P=0.047),and the N200 amplitude of women was significantly higher than that of men((-1.05±0.53)µV,(-2.58± 0.53)µV).In P300 component,the main effect of sex was significant(F(1,32)=12.044,P=0.001),and the P300 amplitude of women was higher than that of men((2.46±0.27)µV,(1.15±0.27)μV).In the late LPP composition,the main effect of sex was significant(F(1,32)=18.998,P＜0.001),and the amplitude of LPP in women was significantly higher than that in men((3.25±0.34)µV,(1.13±0.34)μV).Conclusion Positive reappraisal and detached reappraisal can effectively regulate the subjective emotional experi-ence of negative emotions,and have a greater early emotional response.
