Abstract: The phonological similarity effect refers to the finding that a list of similar-sounding items is recalled less well than a list of dissimilar-sounding items. A strong prediction of the phonological store hypothesis, based on Baddeley's (1986, 1992) working memory framework, is that irrelevant speech should inter;act with the phonological similarity effect. We report three experiments that demonstrate that irrelevant speech eliminates the phonological similarity effect for visual but not for auditory items. In this respect, irrelevant speech functions much like articulatory suppression. Implications for the phonological store and changing state hypotheses are discussed.
