Facial stimuli (in bold) of each block are identical across three conditions; auditory stimuli (in italic) are identical across standard and deviant trials within each block. In each block of each condition, MMN was calculated by subtracting the ERP responses to Standards from that to the Deviants in the same block. i.e., in each block, MMN = Deviant (10%)—Standard (80%).
