The effect of vision and hearing loss on listeners' perception of referential meaning in music

The purpose of the present study was to examine the effect of vision and hearing loss on listeners' perception of referential meaning in music. Participants were students at a state school for the deaf and blind, and students with typical hearing and vision who attended neighboring public schools (N = 96). The music stimuli consisted of six 37-second randomly ordered excerpts from Saint Saëns, Carnival of the Animals. The excerpts were chosen because of their use in similar studies and the composer's clearly intended meaning conveyed in the titles of the excerpts. After allowing for appropriate procedural accommodations for participants with hearing or vision loss, all participants were asked to select the image portrayed by the music. A univariate ANOVA was computed to address the research question, "Do students with vision or hearing loss assign the same visual images to music as students without such sensory losses?" Data were analyzed to examine the effects of sensory condition as well as age and gender. A significant main effect was found for sensory condition, with follow up tests indicating that participants with typical hearing and vision agreed with the composer's intended meaning significantly more often than did participants with vision or hearing loss. No significant main effects were found for gender or age, and no significant interactions were found. Summary data indicated that selected images were more easily identified, or were more difficult to identify across conditions. The data also revealed an order of difficulty and patterns of confusion that were similar across sensory conditions and ages, indicating participant responses were not random, and that some referential meaning in music is conventional.
