Abstract
Over the last 20 years, alternative approaches to working memory have been developed that emphasize the articulated architecture of the system and its limits in the amount of information that can be stored and processed. It was on this basis that Cornoldi and Vecchi (2003) put forward a formulation of the working memory model giving a new account of the organization of working memory proposed by the classical Baddeley (1986) model. According to this novel concept, ‘working memory system and its subsystems can be viewed as representatives of wellcharacterised groups of processes along continuous dimensions rather than as discrete entities’ (Cornoldi & Vecchi, 2003, p. 50). Working memory functions are not rigidly separated, but instead thought of as being linked in a continuous fashion along horizontal and vertical dimensions. In other words, the continuity model is characterized by two fundamental dimensions based on continuum relations: the horizontal continuum, related to the various types of material involved (e.g., verbal, visual, spatial, haptic); and the vertical continuum, related to the types of process, requiring some degree of active elaboration and manipulation of information .
