Fred Dick and I have been doing some work with a long-short tone duration
identification task (50ms vs 90ms) where tone frequency is chosen from
one of x values in a truncated range (e.g., 800Hz, 920Hz, 1000Hz,
1080Hz, 1200Hz). (You might be familiar with this
paradigm from Mondor & Bregman, 1994).
We have found a weak but quite reliable effect, where subjects tend to
judge lower frequencies more often as 'long', and higher frequencies as
'short'. This was unexpected yet remarkably consistent
across a lot of experiments. We have been
unable to track down mention of this in the literature.
We did dig up a few papers that purported to be on the general topic of
frequency effects on duration judgments, but these ended up being about
different things entirely...
We wondered whether anyone might be familiar with
literature we've missed- or maybe even have encountered something like
this before yourself?
Best wishes,
Lori & Fred
