Before revision:  Our results revealed that the P1 ERP component was not modulated by the mimicry manipulation while the N170 amplitude was larger in the blocked mimicry condition when compared to the free mimicry condition selectively for the face stimuli. Interestingly, this modulation interacted with the alexithymic traits, with a reduction of the N170 amplitude modulation as a function of the facial mimicry manipulationfor participants with the highest levels of alexithymic traits.
After revision:  Our results revealed that the P1 and N170 ERP components were not sensitive to mimicry manipulation. However, when taking into account alexithymic traits, with a reduction of the N170 amplitude modulation as a function of the facial mimicry manipulationfor participants with the highest levels of alexithymic traits.
