Embodied simulation theory posits that perception of emotional signal can simulate related state in motor, somatosensory and affective systems. Electromyographic activity was recorded to predict the mimicry effect. We recorded EMG activity of 6 facial muscles during EFE identification/categorisation for investigating the effects of social valence contexts (positive , negative or neutral) on the perception of emotional facial expressions (EFE). EMG activity were recorded of the participants when they were looking at emotional facial expressions.EMG responses were enhanced irrespective of congruency between emotional facial expression and valence of social primes. Increased embodied responses were observed after exposure to social valence. We expected congruent primes should increase embodiment processes (i.e., a greater EMG activity for the muscles associated with that emotion).We observed that the effect of social prime was not systematic but highly dependent of the target emotion.
