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
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.

Kind regards,

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.

Thanks
