Working Memory Working memory is a component of the memory system that is necessary for staying focused on a task, blocking out distractions, and keeping up-to-date and aware about what is happening in the surrounding physical environment. It is also immediately available and active. One popular account of working memory was presented by Alan Baddeley and Graham Hitch (Bjorklund, 2012). According to the Baddeley and Hitch model, working memory is a multicomponent system, capable of both storing and manipulating information, which includes the phonological loop (also known as the articulatory loop), the visuospatial sketchpad, and the central executive. The phonological loop is used for manipulating, storing, and coding verbal, speech-based information (Bjorklund, 2012). It is proposed to have been a fundamental element associated within the origin of vocal language in human evolution (Alboitiz, 2010). The visuospatial sketchpad performs a similar function for coding visual and spatial information. Both the phonological loop and visuospatial sketchpad are supervised by the central executive. The central executive stores information and serves as an attentional control system (Baddeley, 2002). Many studies have been conducted on each component of the Baddeley and Hitch model, including evidence and functional significance of the phonological loop, as well as the visuospatial sketchpad (Baddeley, 1994).
