Word length and phonological similarity effects in simple, complex, and delayed serial recall tasks: Implications for working memory

Some current models of working memory argue that a passive short-term store is not involved in more dynamic working memory tasks. Other models argue t hat standard short-term memory and working memory tasks rely on common stor age facilities. We examine these issues by exploring two signature effects of passive short-term storage in simple span, complex span, and Brown-Peter son tasks. The finding that all three tasks show word length and phonologic al similarity effects suggests that common processes or storage mechanisms are involved in all tasks. The implications for models of working memory ar e discussed.
