Re: Streaming and temporal accuracy

Dear 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

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.

Dear Colleagues,

My students and I are preparing to do a quantitative study of the
inaccuracy of temporal coordination between stream-segregated sound
patterns. 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.
