Abstract

The formation of auditory events requires integration between successive sounds. There is a temporal limit below which a single sound event is perceived while above which a second perceptual event is formed. Behavioral studies applying the Temporal Order Judgment paradigm showed that this boundary is between 20 and 70 ms. Here we provide event-related potential (ERP) evidence from two experiments showing a qualitative change in the processing of tone pairs between 25 and 75 ms within-pair inter-stimulus intervals (ISI). We also show that this temporal boundary can be influenced by the immediate acoustical context, the statistical distribution of the ISIs within the sequence of tone-pairs.
