It occurs to me that the duration of sequential elements can also affect the listener's ability to distinguish the individual events. Thus, when a sequence of, say, tones is presented with tonal duration of 200 ms, one can hear that the sequence has individual tones in it. If the tempo is stepped up so that the tonal duration is now 25 ms, one hears a single sound. Warren has repeatedly pointed out this perceptual distinction, which may be relevant to the issue of the perceptual grouping across time. Kathy
