The decay of pitch memory during rehearsal.

The present study investigates the decay of pitch memory over time. In a delayed pitch comparison paradigm, participants had to memorize the pitch of a Shepard tone, with silent, overt, or without any rehearsal. During overt rehearsal, recordings of the rehearsing were effectuated. Performance was best for silent rehearsal and worst for overt rehearsal. The differences, although partially significant, were not marked. The voice pitch during overt rehearsal was compatible with a random walk model, providing a possible explanation of why rehearsal does not improve the retention of the pitch trace.
