Re: Pure-Tone Frequency Discrimination

[Al Bregman <al.bregman@xxxxxxxxx>]

Hi Vijay,

The rationale for conventional sets of tones is that of comparability
with the results of other experiments.  My guess is that the set {200,
400, 800 ...} comes from the "speech and hearing" tradition
(audiology, speech therapy, etc.), since these are the settings on
audiometers.  The other set {500, 100, 2000, ...} seems to come from
the psychophysical tradition.  So it really depends on whose research
you want to compare your results with.

Best,
Al
