Outline and evaluate working memory model

Baddeley and Hitch proposed that memory has 4 components; the central executive, phonological loop, visuospatial sketchpad and the episodic buffer. The central executive decides how to share out and direct attention to incoming information. The phonological loop can be thought of as a maintenance rehearsal mechanism for retaining verbal information. It is sub-divided into two other components; the phonological store (inner ear), which holds acoustically coded information, and the articulatory process (inner voice), which allows for sub vocal rehearsal (words you are about to say). Furthermore, the visuospatial sketchpad (inner eye) is responsible for storing visual and spatial information. In other words, it codes information in images and can create and manipulate visual and spatial images. Finally, the episodic buffer. This component takes information from different sources and integrates them together. 

The working memory model is an improvement over the multi-store model. It demonstrates how the short term memory works because…
