A FRÖHLICH EFFECT IN MEMORY FOR AUDITORY PITCH: EFFECTS OF CUEING AND OF REPRESENTATIONAL GRAVITY

Abstract

Memory for the initial pitch of an auditory target sequence that increased or decreased in frequency was displaced forward in the direction of pitch motion, and this is consistent with a Fröhlich effect. Displacement was decreased (not eliminated) by an auditory cue presented before the target was presented, and displacement was smaller if a valid auditory cue was presented than if an invalid auditory cue was presented. A visual cue that indicated whether the initial pitch would be relatively low or relatively high did not influence memory for the initial pitch. Displacement was larger for descending pitch motion than for ascending pitch motion, and this is consistent with an influence of representational gravity. The data suggest that the mental representation of auditory frequency space exhibits some of the same spatial biases that are exhibited in the representation of visual physical space.
