• Who developed the working memory model?

  Baddeley and Hitch
• What part of memory is the WMM an explanation for?

  Short-term memory
• What is the WMM concerned with?

  The 'mental space' active when we are temporarily storing and manipulating information
• What are the five main components of the WMM?

  Central executive, phonological loop, visuo-spatial sketchpad, episodic buffer, long-term memory
• What role does the central executive have?

  A 'supervisory' role
• Does the central executive store information?

  No
• What is the processing capacity of the central executive?

  Very limited
• What does the central executive do?

  Monitors incoming data, focuses and divides our limited attention and allocates subsystems to tasks
• What two components is the phonological loop split into?

  1 . Phonological store

  2 . Articulatory process
• What is the phonological store?

  Stores words we hear
• What is the articulatory store?

  Repeats sounds/words in a loop to keep them in working memory while needed (allows maintenance rehearsal)
• What is the capacity of the phonological loop believed to be?

  2 seconds worth of what you can say
• What does the phonological loop do?

  Deals with auditory information and preserves the order in which information arrives
• What does the visuo-spatial sketchpad do?


  Stores visual and/or spatial information when required
• What two components is the visuo-spatial sketchpad divided into according to Logie?

  1 . Visual cache

  2. Inner scribe
• Who split the visuo-spatial sketchpad into two components?

  Logie
• What is the capacity of the visuo-spatial sketchpad according to Baddeley?

  3 or 4 objects
• What is the visual cache?

  Stores visual data
• What is the inner scribe?

  Records the arrangement of objects in the visual field
• What is the episodic buffer?

  A temporary store for information, integrating the visual, spatial and verbal information processed by stores
• What does the episodic buffer link working memory to?

  Long-term memory
• What can the episodic buffer be seen as?

  The storage component of the central executive
• What is the capacity of the episodic buffer?

  About 4 chunks
• What does the episodic buffer maintain a sense of?

  Time sequencing - recording episodes that are happening
• What can the working memory model explain that the multi-store model cannot?

  Dual-task performance
