Working Memory

According to Baddeley's model, Working Memory consists of three components: the visuospatial sketchpad, the phonological loop, and the central executive, that work together to process incoming information. The visuospatial sketchpad governs the processing of visual information, the phonological loop auditory information, and the central executive allocates information and energy to the correct component. So, when you need to maintain visual information (such as an idea of what someone looks like), the central executive activates the visuospatial sketchpad; when the phonological loop is needed (such as to remember someone's phone number) the central executive activates it. The information is processed as it passes through sensory memory, or as it is pulled out of storage in long-term memory.
