Some listeners are insensitive to the direction of pure-tone frequency changes
when the standard frequency is roved widely over trials, but less so when the
standard frequency is fixed and trial-by-trial feedback is provided. The present
experiment tested the hypothesis that fixing the standard frequency and providing
feedback is advantageous for direction-impaired listeners because under these
conditions the listeners can learn to respond correctly without genuinely
perceiving frequency-change direction. This hypothesis was ruled out by the
experiment. It appears instead that direction-impaired listeners find it
difficult to ignore the irrelevant frequency changes introduced by roving.
