Recent research suggests that linguistic and musical information are processed by shared working memory resources in non-musicians. However, it is still unclear how musical information is actively maintained by those with extensive musical experience. Some evidence suggests that those with musical experience may utilize distinct processing systems for the active maintenance of linguistic and musical information. To explore this possibility, a cross-modal interference paradigm was used in which those with and without musical experience were presented with an initial stimulus (word or chord), followed by intervening stimuli (words, chords, or silence), and then a comparison stimulus (word or chord). The participants' task was to indicate whether the comparison stimulus was the same or different from the initial stimulus. Results revealed a pattern of data that would be expected if the active maintenance of linguistic and musical information was accomplished by distinct systems in those with musical experience and a unitary system in non-musicians.

Abstract. The present study sought to explore whether musical information is processed by the phonological loop component of the working memory model of immediate memory. Original instantiations of this model primarily focused on the processing of linguistic information. However, the model was less clear about how acoustic information lacking phonological qualities is actively processed. Although previous research has generally supported shared processing of phonological and musical information, these studies were limited as a result of a number of methodological concerns (e.g., the use of simple tones as musical stimuli). In order to further investigate this issue, an auditory interference task was employed. Specifically, participants heard an initial stimulus (musical or linguistic) followed by an intervening stimulus (musical, linguistic, or silence) and were then asked to indicate whether a final test stimulus was the same as or different from the initial stimulus. Results indicated that mismatched interference conditions (i.e., musical – linguistic; linguistic – musical) resulted in greater interference than silence conditions, with matched interference conditions producing the greatest interference. Overall, these results suggest that processing of linguistic and musical information draws on at least some of the same cognitive resources.
