Visual perception of musical notation: Registering pitch symbols in memory

Music bears formal relations to language which suggest that perceptual processes in the two modes may also be similar. These experiments examined the way in which experienced musicians differed from non-musicians in their recognition of briefly exposed pitch notation. Experiments I and II together demonstrated that musicians are superior to non-musicians in their immediate written recall of stimuli containing more than three notes, but only when the stimulus is available to them for 150 ms or more. These results are accounted for well by a model proposed by Coltheart (1972) for letter perception under conditions of brief exposure. In this model, two coding processes act simultaneously on the stimulus, one a fast visual coding, and the other a slower, but more permanent abstract (or name) coding. In this case non-musicians appear to be lacking a second, abstract, coding which musicians possess. Experiments III and IV attempted to investigate the nature of the abstract code for musicians by presenting various types of interference in the linguistic or musical mode. Neither concurrent letter naming nor concurrent memorization of pitches appeared to cause a decrement in the original visual task, suggesting that musicians may not have been using simple naming or pitching transformations in coding the visual input.
