context sounds and pitch discrimination thresholds

[Marion Cousineau <marioncousineau@xxxxxxxxx>]

Dear list,

I am interested in looking at the effect of precursor
sounds on pitch discrimination thresholds.
That is somehow looking at the effect of context sounds,
but I am NOT talking about tonal context.

An example would be comparing thresholds obtained with a
standard 2I-2AFC, with thresholds obtained with the same
procedure but where each trial is preceded by two repetitions
of the reference, for instance.
The underlying question is whether or not a repetition of the
reference (or another sound close in pitch) can sharpen the 
internal representation of the following test sounds.

I haven't been able to find papers where this kind of effects were 
investigated, and was wondering if some of you knew about and 
could point me to existing data on that matter.

Cheers,

Marion
