In 2000, Baddeley added a new component to the existing model, known as the episodic buffer, representing the integration of phonological, visual and spatial information in addition to semantic information, musical information, particularly not covered by the traditional 'slave systems'.

The process of rehearsal is assumed to entail some type of sub-vocal articulation, not only works for maintaining information within the storage system, but also serves the purpose of registering visual stimuli within the storage, given the objects can be named. Hence, if a small sufficient quantity of information is to be provided, it can be maintained for an indefinite period through the method of continuous rehearsal. ...Show more
