Baddeley (1986) has divided the WM into three components: the central executive and its two 'slave systems', the visual-spatial sketchpad (VSS) and the phonological loop (PL). According to Baddeley, the PL consists of a passive phonological store and of an articulatory control process (ACP). The phonological store holds auditorily presented verbal information and is subjected to time decay. In principle, the ACP's rehearsal mechanism could maintain the information indefinitely in the phonological store if the time taken to rehearse is kept within the decay time (about 1.6 to 1.8s). Another function of the ACP is the transcoding of visual input, after which this latter accesses the phonological store. Consequently, Baddeley claims there is a correlation between speech rate and memory span, the recall for short words would ...
