The working memory model

• The working memory model:

  1. Central executive
  2. Episodic buffer
  3. Visuo-spatial sketchpad
  4. Phonological loop
  5. Articulatory process (inner voice)
  6. Phonological store (inner ear
  7. Long term memory

  
• The working memory model:

  Created by Baddeley & Hitch (1974)

  • Central executive - directs attention, allocates tasks to slave systems, has no storage
  • Episodic Buffer - a temporary store that integrates information to experience a mental episode of what is being experienced & maintains time sequencing
  • Visual-spatial sketchpad - planning & processing visual & spatial tasks. Logie divided it into the visual cache for what items look like & the inner scribe for the spatial relationship between items
• The working memory model:

  • Phonological loop - preserves order of auditory information
  • Phonological store - holds the words you hear
  • Articulatory process - performs maintenance rehearsal
• The working memory model AO3:

  • ✅ Evidence from brain scan studies - different parts of the brain are activated for differet tasks - separate parts
  • ✅ Dual task performance - pts perform better when doing tasks of different natures than doing two verbal tasks - different slave systems
  • ❌ Functioning of central executive - too vague, doesn't explain how information is transferred - too simplistic
  • ✅ Evidence for PL & AP - explains word length effect. The PL has a duration of 2 seconds so long words can't be rehearsed. When given an articulatory suppression task, the effect disappears
• The working memory model AO3:

  • ✅ Evidence from brain scan studies
  • ✅ Dual task research
  • ❌ Functioning of central executive
  • ✅ Evidnece for the phonological loop & the artciulatory process
