Describe and Evaluate the Working Memory Model (12 marks)
Information transfers into the central executive where information is sorted out and
directed to the areas that deal with the information.
The phonological loop consists of two parts, the articulatory process and the phonological
store. The articulatory process is the `inner voice' where sub-vocal rehearsal takes place.
The phonological store is the `inner ear' and encodes information acoustically.
The episodic buffer gets different pieces of information and places them together into
schemas. The visuo-spatial sketchpad is the `inner eye' and stores information visually using
imagery and spatial awareness.
A weakness of the model is that little is known about the central executive. Researchers
believe it consists of more than one component but the model does not take this into
account. Therefore, we can say that the model appears to be reductionist because there is
a lack of detail to important areas.
A strength of the model is that it tells us more about how the short-term memory works
than the multi-store model of memory. It also suggests that the length of the information is
more important than the capacity of the component. This increases credibility as we know
more information as to how the short-term memory works and can use it as an explanation
to how memory works.
A weakness of the model is that research to help create the model was done in a laboratory,
therefore, it lacks ecological validity as it does not have or cannot be used in a real-life
setting. The situations were artificial and ambiguous tasks were how information was
received. This reduces validity and reliability of the model.
