- Proposed a multi-component model of memory consisting of: The central executive, phonological loop,visuo-spatial sketchpad, episodic buffer (2000).
- Baddeley & Hitch (1974)
- Working memory is used when performing cognitive functions.
- WMM vs MSM
- The WMM model attempts to rectify some of the criticisms of the MSM model by proposing a more dynamic view of STM.
- The WMM sees the STM as working memory, a dynamic construct that allows for the manipulation of information within the STM store.
- This is different from the proposal of Atkinson & Shiffrin that STM is a static structure that just temporarily stores information.
- Information in LTM is accessed/transferred to WM to be combined with new information/ manipulated.
- WMM vs MSM
- Controls attention and filters sensory information it receives to sub systems.
- The central executive(He
- An attentional system that processes all sensory information.
- Little is known about the CE, the vagueness means it can be used to describe a variety of resul
- Limited in capacity, works on one type of information at a time but switches information between different inputs
- The central executive(He
- Deals with auditory information and the order of information.
- The phonological loop
- The primary acoustic store(inner ear)-stores words recently heard.
- Baddeley (1986) divided the PL into two sub-systems.
- The articulatory process(inner voice) -keeps information through sub-vocalized repetition of information and is linked to speech production.
- The phonological loop
- It was added because it was suggested that the WMM needed a general store to operate correctly.
- The episodic buffer
- The EB explains how it's possible to temporarily store stuff from all syste
- Information is integrated from the EB to other sub-systems.
- The EB tries to correct problems caused by the limited capacity of the PL &VSS.
- The episodic buffer
- Temporarily stores visual & spatial information, helping people interact with their surroundings.
- The visuo-spatial sketchpad
- 'The inner eye' - handles non-phonological.
- Information is coded and rehearsed through mental picture.
- A passive store of form and colour.
- Divided the VSS into two sub parts.The visual cache(colour)and inner scribe(spatial).
- The visuo-spatial sketchpad
- Logie (1995)
