Auditory illusion analogous to the Baldwin figure in vision.

An auditory illusion was demonstrated in which there was perceptual shortening of the temporal interval contiguous to a low frequency (large) tone and/or perceptual lengthening of the temporal interval contiguous to a high frequency (small) tone. This auditory analogy to the Baldwin figure was demonstrated after first determining that there was a symmetrical expansion of perceived time during the auditory filled-duration illusion.
