Working memory model

• What is the working memory model


  Suggests STM is different sub units coordinated by central decision maker
• what is the central executive as part of the working memory model


  supervisor, coordinater role, very limited capacity
• what is the phonological loop as part of the working memory model


  Auditory info (reading), phonological store stores what we hear, articulatory process allows maintenance rehearsal, coding accoustic capacity 2 seconds,
• what is the visuo-spatial sketchpad as part of the working memory model


  visual info, visual catch: stores visuals, inner scribe: stores arrangements, coding is visual or spatial capacity limited
• what is the episodic buffer as part of the working memory model


  storage of other stores before it goes into LTM, capacity is 4 chunks
• working memory model diagram


  central executive

  <> visuospatial sketchpad

  <> episodic buffer <> LTM

  <> phonological loop (articulatory system<> phonological store)
• What is a strength of the working memory model


  Brain damage victim ‘KF’ broken phonological loop, working visuospatial sketchpad (recall better visual data than auditory) > supoorts that there are separate STM stores

  However case studies are very specific and cannot be generalised
• What is a strength of the working memory model


  supporting evidence by badderly who had participants do visual + verbal and visual + visual recall tasks > same store dual task lowered efficiency it was competing with itself > shows there are seperate STM stores
• What is a weakness of the working memory model


  Studies used tasks that are unlikely to be used in life in highly controlled conditions > low validity
