Baddeley and Hitch (1974) suggested the working memory model (WMM) to address
some of the shortcomings of the multi-store model. They believed that short-term
memory (STM) is an active process, hence the name "working memory," and that STM
is made up of several stores, not just one unitary store. The WMM is managed by the
central executive, who also focuses on one of the three slave systems. The
phonological loops, which deal with auditory information, contain both the articulatory
control process and the phonological store, which holds the words you hear and allows
for maintenance rehearsal of acoustic information. Planning spatial tasks involves using
the visuospatial sketchpad (VSS). The inner scribe, which deals with spatial
relationships and saves the layout of objects in the visual field, and the visual cache,
which stores visual information, are both parts of the VSS. The episodic buffer, a
general repository for both visual and aural information, was added by Baddeley in
2000. The episodic buffer's function is to combine data from the other three components
and move it from short-term memory to long-term memory.
Dual task studies are one source of the working memory models' strength. Baddeley
and Hitch (1976) discovered that participants' performance on two tasks is hampered
when they are required to use their phonological loop. However, when a task demands
the participant to use both their visuospatial sketchpad and phonological loop at the
same time (remembering a list of numbers), their performance is not impacted. This
lends validity to the paradigm and the notion that our STM system consists of numerous
components.
