According to the multicomponent view of working memory, both auditory-nonverbal information and auditory-verbal information are stored in a phonological code and are maintained by an articulation-based rehearsal mechanism (Baddeley, 2012). Two experiments have been carried out to investigate this hypothesis using sound materials that are difficult to label verbally and difficult to articulate. Participants were required to maintain 2 to 4 sounds differing in timbre over a delay of up to 12 seconds while performing different secondary tasks. While there was no convincing evidence for articulatory rehearsal as a main maintenance mechanism for auditory-nonverbal information, the results suggest that processes similar or identical to auditory imagery might contribute to maintenance. We discuss the implications of these results for multicomponent models of working memory.
