Subject: Re: Streaming and temporal accuracy From: Leon van Noorden <leonvannoorden(at)CHELLO.BE> Date: Tue, 28 Jun 2005 09:45:53 +0200Dear Michael, In my dissertation "Temporal Coherence in the Perception of Tone Sequences", I have described a kind of 'Von Bekesy' back and forth relative temporal tracking method of the two parts of a continuous alternating tone sequence. Although this may not be the best psychophysical method for determining temporal discrimination in general, I have applied it nevertheless as I had found that the continuity of the tone sequences was essential to obtain the strong effects of loss in temporal acuity. Anything that generates a discontinuity in the sequences gives the listener, by way of speaking, the possibility to go back in his echoic memory and have a second look on what happened. In one of the IPO annual progress reports we describe the measurements of the discrimination of the temporal gap between two tones of different frequency with a 2 alternative forced choice method. If the jump is embedded in a longer sequence, e.g. a a a b b b, the discrimination deteriorated more strongly with the increase of the frequency jump. If you want I can dig it out and scan it for you.

Do you have advice regarding the best procedure to use (and perhaps a pointer to the paper that you think offers the best evidence for this inaccuracy)? Perhaps you could cc me when replying to the list.
