pitch discrimination

["Robert J. Zatorre" <MD37@xxxxxxxxxxxxxxxx>]

Dear List

A reviewer of a recent paper of ours has written the following:

"...I thought it was well established that 10 to 30% of normal subjects
cannot judge which frequency [in a pair of pure tones] is higher or lower
(above chance), while all subjects are generally able to judge if two
frequencies are identical or not."

My question: is this, in fact, well established, as the reviewer claims,
and if so, what might be the reference for this?

Any leads you all can give us would be appreciated

Thanks

Robert
