Working memory model

• Phonological loop is responsible for the storage of short-term auditory information.
• Primary acoustic store holds auditory memory traces. It has a limited capacity and memory decays after 2 seconds unrehearsed
• Articulatory loop subvocally rehearses auditory information
• Episodic Buffer - A temporary store that links items in working memory to form coherent episodes. It allows us to integrate different types of information such as visual images, sounds, smells etc. It also helps us to retrieve memories from long-term memory by providing contextual cues.
• Central executive controls the other components of working memory.
• The visuospatial sketchpad (inner eye) holds the information we see


  • Visual cache store - form and colour
  • inner scribe - retrieval and rehearsal
• Working Memory Model

  • Phonological loop
  • Visio-Spatial Sketchpad
  • Central Executive
• Another strength of WMM is that less reductive as consists of multiple components such as the central executive phonological loop, visuospatial sketchpad. Allows for a more nuanced understanding of how we process information.
• Weakness 3 of working memory model

  Episodic buffer was added in 2000 as a storage system that retrieves inf from LTM. Shows working memory model was not a complete explanation of memory
• Phonological loop

  Primary acoustic store

  Articulatory loop
• Anything that uses spatial awareness such as navigation uses the visuospatial sketchpad.
