| 1 | Suppression dampens unpleasant emotion faster than reappraisal:Neural dynamics in a Chinese sample显示文摘The timing dynamics of regulating negative emotion with expressive suppression and cognitive reappraisal were investigated in a Chinese sample. Event-Related Potentials were recorded while subjects were required to view, suppress emotion expression to, or reappraise emotional pictures. The results showed a similar reduction in self-reported negative emotion during both strategies. Additionally, expressive suppression elicited larger amplitudes than reappraisal in central-frontal P3 component(340–480 ms). More importantly, the Late Positive Potential(LPP) amplitudes were decreased in each 200 ms of the 800–1600 ms time intervals during suppression vs. viewing conditions. In contrast, LPP amplitudes were similar for reappraisal and viewing conditions in all the time windows, except for the decreased amplitudes during reappraisal in the 1400–1600 ms. The LPP(but not P3) amplitudes were positively related to negative mood ratings, whereas the amplitudes of P3, rather than LPP, predict self-reported expressive suppression. These results suggest that expressive suppression decreases emotion responding more rapidly than reappraisal, at the cost of greater cognitive resource involvements in Chinese individuals. | YUAN JiaJin LONG QuanShan DING NanXiang LOU YiXue LIU YingYing YANG JieMin | 2015 | Science China(Life Sciences)2015，58，5： | 11 |
| 2 | Gender Role,But Not Sex,Shapes Humans’Susceptibility to Emotion显示文摘It is unknown whether the famous sex-related difference in emotion processing is accounted for by biological sex,gender role,or their interaction.To clarify the issue,in Study 1 we recorded event-related potentials in response to negative and positive images of diverse intensities when 47 masculine(26 males)and 47 feminine(22 males)subjects performed a non-emotional task.The occipital P1 and N1 amplitudes were larger in women than in men,while feminine subjects showed larger N1 amplitudes than masculine subjects,regardless of sex.Moreover,feminine subjects showed enhanced frontocentral N2(210–270 ms)amplitudes for highly and mildly negative than for neutral stimuli,while masculine subjects showed an emotion effect only for highly negative stimuli.The feminine-specific effect for mildly negative stimuli was positively correlated to the feminine score,and this correlation was located to the anterior cingulate and the superior and medial frontal gyri.Furthermore,feminine but not masculine subjects showed enhanced parietal P3(330–560 ms)amplitudes for highly and mildly positive than for neutral stimuli,an effect positively related to the feminine score and localized to the precuneus,posterior cingulate,and superior temporal gyrus.Machine learning analyses verified that single-trial N2 and P3 amplitudes of feminine subjects reliably discriminated the intensity of negative and positive stimuli,respectively.For ecological considerations,in Study 2 we used an observational approach(n=300)and confirmed that feminine gender role,rather than biological sex,predicted individual differences in daily experience of emotion-related psychopathological symptoms.These findings provide solid evidence for the critical impact of gender role rather than sex on emotional susceptibility. | Jiajin Yuan Hong Li Quanshan Long Jiemin Yang Tatia M.C.Lee Dandan Zhang | 2021 | Neuroscience Bulletin2021，37，2： | 4 |
| 3 | Facial Expression Enhances Emotion Perception Compared to Vocal Prosody: Behavioral and fMRI Studies显示文摘Facial and vocal expressions are essential modalities mediating the perception of emotion and social communication. Nonetheless, currently little is known about how emotion perception and its neural substrates differ across facial expression and vocal prosody. To clarify this issue, functional MRI scans were acquired in Study 1, in which participants were asked to discriminate the valence of emotional expression(angry, happy or neutral) from facial, vocal, or bimodal stimuli. In Study 2,we used an affective priming task(unimodal materials as primers and bimodal materials as target) and participants were asked to rate the intensity, valence, and arousal of the targets. Study 1 showed higher accuracy and shorter response latencies in the facial than in the vocal modality for a happy expression. Whole-brain analysis showed enhanced activation during facial compared to vocal emotions in the inferior temporal-occipital regions. Region of interest analysis showed a higher percentage signal change for facial than for vocal anger in the superior temporal sulcus. Study 2 showed that facial relative to vocal priming of anger had a greater influence on perceived emotion for bimodal targets, irrespective of the target valence. These findings suggest that facial expression is associated with enhanced emotion perception compared to equivalent vocal prosodies. | Heming Zhang Xuhai Chen Shengdong Chen Yansong Li Changming Chen Quanshan Long Jiajin Yuan | 2018 | Neuroscience Bulletin2018，34，5： | 0 |
