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.
After revision:  Our results revealed that , on average, both 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.
