The working memory model was constructed by Baddeley and Hitch in 1974. the model consists 3 main components of the working memory model; the central executive, the phonological loop and the visuo-spatial sketch pad.

The central executive acts like a conductor and allocates and coordinates jobs to the other components.

The phonological loop is the inner ear and inner voice and this is responsible for processing phonological information, it’s acts as an auditory short term memory. It is a loop because it can store and repeat sound for a period of around 20-30 seconds. It has two subcomponents, the phonological store and articulatory control process. The phonological store is the inner ear and contains snippets of sounds either from the outside world or recalled from long term memory. The articulatory control process is the inner voice which essentially is our own voice inside our heads. For example, reading something and hearing your own voice in your head.

Lastly, the visuo-spatial sketchpad is the inner eye which processes visual and spatial information, for example looking at photographs. It can manipulate images in different dimensions, for example recalling a friend’s face from long-term memory in two dimensions and imagining walking around the kitchen in your house in three dimensions.

A strength of this model is that it shows that was have different stores which allow us to do different things at the same time. An example of this is the case study of KF. KF suffered brain damage from a motorcycle accident which damaged his short-term memory. The damage was mainly for verbal information and his memory for visual information was unaffected. This shows that there are separate STM components for visual information (VSS) and verbal information (phonological loop).
Another strength is that The working memory model explains a lot more than the multistore model. It makes sense of a range of tasks like verbal reasoning, comprehension, reading and...
