Hi, sorry for the somewhat belated response to Robert's original query. I'm not sure how relevant this is to the information you need but an additional aspect relates to streaming. Certainly in situations in which the two (pure) tones concerned are: a) part of a repetitive pattern b) short duration and close c) more than a few semitones apart then I have a tendency to hear the two streams formed (one high tone stream, one low tone stream, each with the same tone, slow rate of repetition) with the tones occurring at the same time, so that it is no longer possible to say which came first. I cannot recollect whether this happens immediately the 2 streams appear or only after they have become well established, so cannot say whether this would be likely to affect judgement of the order of two short tones presented in isolation (does anyone else experience this phenomenon?).
