The working memory model

• • The working memory model was produced by baddley and hitch as they argued that the MSM is to simplistic. The WMM focuses on the STM only he believes that it is not a unitary store that passes information to LTM. Baddley suggested that the STM is used to process, filter and combine multi types of information and is an active processor rather than a passive store holding onto information and passing it down to the LTM. • As the STM has a number of different stores because dual task performance shows that tasks are poorly done together than separately. This suggests that there’s one store for visual processing and separate store for sound
• The WMM consists of slave systems organised by the central executive. The central executive prioritises information by making decisions about which issue deserves attention and which should be ignored and filters information. The information from the environmental stimuli is delegated to the relevant slave systems ( Episodic buffer, visual spatial sketchpad and phonological loop)
• 
  

  The first subsystem is the phonological loop this processed auditory information ( sound and words ) and is subdivided into the phonological store the inner ear which holds words that have been heard for 1-2 secs and the articulate process the inner voice which holds words you hear and see and silently repeats in a loop like a inner voice .

  
  

  
  

  The second sub system is the visual spatial sketchpad which is responsible for processing visual and spatial information. Lodgie divided the VSS into the visual cache which stores visual data like what things look like and the inner scribe which records the arrangements of objects in the visual field. The VSS has the capacity of 3-4 items.

  
  

  
  

  
  

  
  

  The third subsystem is the episodic buffer where visual verbal answers spatial information is integrated to the LTM.
