Different Neural Mechanisms for Group Membership Effect on Emotional Mimicry to Happy and Angry Faces: A Multimodal Study with Electromyography and Electroencephalography

Using a multimodal method combining both electromyography (EMG) and electroencephalography (EEG),with HMI vs. LMI ERP difference on the four ERP components as outcome measure of emotional mimicry, we detected in-group preference in both emotional mimicry to happy faces (EMH) and angry faces (EMA).
