working memory model

• 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)
