摘要:
We recorded event-related brain potentials (ERPs) to two different infrequent deviant tones presented successively within the repetitive sequence of a standard tone. A separate mismatch negativity (MMN) component was elicited by each of the two deviants when the interval separating their onsets was 300 ms. However, only a single MMN component was elicited when the temporal separation between the onsets of the two deviants was 150 ms. Previous studies obtained similar results using two temporally separated deviations carried by a single sound. Taken together, these results support the notion of a general temporal integration mechanism in the formation of auditory events with ca. 200 ms long window. (C) 1999 Elsevier Science Ireland Ltd.
