The effects of unvocalized music on short-term memory

The studies reported here investigated the role of background music in verbal processing. The experiment was a partial replication of Salame and Baddeley (1989), where the effect of music on the recall of digits, was examined, but included an additional key condition where participants heard instrumental music without the words usually associated with it. In this case we used nursery rhymes. In addition, articulatory suppression was manipulated as a tool to look at the role of working memory in the task. The relationship between long-term memory and working memory was further explored by using an implicit memory task to examine verbal memory effects for words associated with the music but not actually heard. The results indicated that background, instrumental music, long-associated with words, significantly impairs concurrent verbal processing. These long-term memory effects on working memory were, however, not associated with implicit memory effects, and no priming was observed.
