title: [Perceptual categories for auditory motion as reflected in mismatch negativity].
abstract: Auditory evoked response and mismatch negativity potential have been studied using the reversed odd-ball paradigm of standard and deviant stimulus presentation. In the experiments, three types of spatial sound stimuli (stationary and moving either gradually or abruptly from the head midline) were presented in three configurations. Each configuration employed one stimulus type as standard and the other two types as deviants. It was demonstrated that the configuration reversals influenced significantly the evoked response and mismatch negativity. The results obtained are discussed as the possible evidence of the categorical perception of auditory motion revealed at the earlier stages of sound processing in the hearing system.
