title: What's working in working memory: a role for the Central Executive.
abstract: Two experiments are reported which seek to explore the nature of the Central Executive of Baddeley's (Baddeley and Hitch, 1974) model of working memory. Experiment 1 uses a dual task methodology to compare performance on two storage tasks, making use of the two slave systems, the Phonological Loop (PL) and the Visuo-Spatial Scratch Pad (VSSP). Results suggest that storage can be thought of as based on the use of slave system independent resources. Experiment 2 uses a similar approach to compare performance on 2 processing tasks, again one PL based, the other VSSP based. These results suggest that processing is based on a central, shared set of resources. The two experiments support both a multiple resources model of working memory and more specifically identify a role for the Central Executive.
