Mismatch negativity amplitude predicts gains in auditory perceptual learning. Mismatch negativity (MMN) amplitude at scalp channel FCz in response to duration+frequency double-deviants presented before and after auditory training (AT) is significantly associated with behavioral gains in auditory perceptual learning. Schizophrenia patients with the largest MMN amplitudes exhibited the largest behavioral improvements in response to 1 h of training. Behavioral improvement (%) is the mean percentage change in baseline vs best score for each level.
