working memory model

Cards (20)

  • What does the working memory model explain?
    How the STM is organised
  • Who proposed the working memory model?
    Baddeley and Hitch
  • What is the role of the central executive in the working memory model?
    It supervises and allocates tasks to slave systems
  • What are the limitations of the central executive?
    Very limited processing and does not store information
  • What does the phonological loop deal with?
    Auditory information
  • What are the two subdivisions of the phonological loop?
    Phonological store and articulatory process
  • What does the phonological store do?
    Stores the words you hear
  • What is the function of the articulatory process?
    Allows maintenance rehearsal
  • What is the capacity of the phonological loop?
    2 seconds
  • How does the phonological loop code information?
    Codes acoustically
  • What does the visuospatial sketchpad deal with?
    Visual information
  • What are the two subdivisions of the visuospatial sketchpad?
    Visual cache and inner scribe
  • What does the visual cache do?
    Stores visual data
  • What is the function of the inner scribe?
    Records the arrangement of objects
  • What is the capacity of the visuospatial sketchpad?
    3-4 objects
  • How does the visuospatial sketchpad code information?
    Codes visually
  • What is the role of the episodic buffer?
    Acts as a backup store
  • How does the episodic buffer link working memory?
    Links working memory to long-term memory
  • What is the capacity of the episodic buffer?
    4 chunks
  • How does the episodic buffer code information?
    Codes anything (modality free)
