ICC, intra-class correlation, using two-way mixed single measures consistency formula (ICC 3, 1 from Shrout and Fleiss, 1979); SZ, schizophrenia group; HC, healthy control group; MMN, mismatch negativity; RP, repetition positivity; DN, deviant negativity. MT, memory trace effect, defined for each component by subtracting value associated with repeated standard 3 from value associated with repeated standard 33. Overall MMN, RP, and DN measures are based on ERP averages of all standards, all deviants, and the resulting ERP deviant-standard difference waves.
