The phonological loop is the subsystem of working memory that deals with auditory information. It consists of two parts: a short-term phonological store with auditory memory traces that are subject to rapid decay and an articulatory rehearsal process that can revive the memory traces.
The multicomponent model of working memory (Baddeley and Hitch 1974) is considered to be one of the most influential models of working memory. According to this model, several components are involved in the execution of working memory: the central executive, the phonological loop, the visuospatial sketchpad, and a fourth component called episodic buffer (Baddeley 2000). Among these components, the phonological loop is specialized for the retention of verbal information over short periods of time. In addition, the phonological loop is comprised of two components, a phonological.
