G. Tehan et al., Word length and phonological similarity effects in simple, complex, and delayed serial recall tasks: Implications for working memory, MEMORY, 9(4-6), 2001, pp. 333-348
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.
