The effects of global and feature‐specific probabilities of auditory stimuli were manipulated to determine their effects on the mismatch negativity (MMN) of the human event‐related potential. The question of interest was whether the automatic comparison of stimuli indexed by the MMN was performed on representations of individual stimulus features or on gestalt representations of their combined attributes. The design of the study was such that both feature and gestalt representations could have been available to the comparator mechanism generating the MMN. The data were consistent with the interpretation that the MMN was generated following an analysis of stimulus features.
