What is the working memory model?

The working memory model explains how short term memory is organised. It consists of four main components that are different by coding and capacity. One of which is the central executive which allocates tasks to one of three slave systems. The slave systems are the phonological loop (for auditory information), visuospatial sketchpad (for visual information) and the episodic buffer which puts the visual and auditory information together in order to form a memory.
