Describe the process of the working memory model 
The Central Exec is the boss. The phonological loop deals with auditory info, has limited capacity and is split into the phonological store and articulatory loop. The PS is the inner ear , whilst the AL is the inner voice and rehearses the information in the ps. The visuo spatial sketchpad is the inner eye, has limited capacity and deals with what information looks like and how it is laid out. It is split into the inner scribe and visual cache.
