To investigate the universality and cultural specificity of emotion processing in children from different ethnic groups (Han, Jingpo and Dai), we conducted three questionnaires, including emotional contagion scale, emotion regulation scale and the Chinese mood adjective check list (CMACL), among 1,362 ethnic Han, Dai and Jingpo participants (Mage = 13.78 years). We found emotion regulation (reappraisal and suppression) mediated the relations between emotional contagion and mood state, relation: (1) emotional contagion (positive and negative) increased positive mood state and decreased negative (...) mood state by reappraisal, and (2) Negative contagion finally increased negative mood state by weaken effect of reappraisal and enhance effect of suppression. Importantly, we found both universality and ethnic cultural specificity in the relations among emotional contagion, emotion regulation, and state mood. Firstly, the cultural specificity: (1) For Dai and Jingpo participants, negative contagion positively predicted reappraisal, while Han participants did not; (2) Jingpo participants demonstrated a weaker negative relation between reappraisal and negative mood state, and a stronger positive relation between negative contagion and suppression; and (3) Dai participants was the only ethnic group that showed a negative connection between negative contagion and positive mood state. Secondly, the emotion universality: Three ethnics both showed positive relations between negative contagion and negative mood, between suppression and negative mood; For all of them, positive contagion positively predicted positive mood state, mediated by reappraisal. In this paper, we discuss universal emotion processes and ethnic cultural differences in these emotion processes. (shrink)

Our prior research demonstrated that the right temporoparietal junction exerted a modulatory role in ingroup bias in emotional mimicry. In this study, two experiments were conducted to further explore whether the rTPJ is a neural region for emotional mimicry or for the modulation of emotional mimicry by group membership in a sham-controlled, double-blinded, between-subject design. Both experiments employed non-invasive transcranial direct current stimulation to temporarily change the cortical excitability over the rTPJ and facial electromyography to measure facial muscle activations as (...) an index of emotional mimicry. After the anodal or sham stimulation, participants in Experiment 1 passively viewed a series of happy clips, while participants in Experiment 2 viewed happy clips performed by ethnic ingroup and outgroup models. fEMG analyses revealed that participants in Experiment 1 showed the same degree of happy mimicry for both tDCS conditions and participants in Experiment 2 showed an ingroup bias in happy mimicry in the sham condition, which disappeared in the anodal condition. Taken together, the present study demonstrated that rTPJ plays a role in the modulation of emotional mimicry by group membership. (shrink)
