working memory model

• who made the working memory model?

  Baddeley and Hitch (1974)
• draw the model

  :

  
• what is working memory?

  refers to the bit of information that you use whilst working on a complex task requiring you to store information as you go along
• why was the working memory model developed?

  the MSM was too simple and a passive store, STM needed to be subdivided
• what do the working memory model suggest about STM?

  it is a dynamic processor of different types of information
• what does the central executive do?

  controls the slave systems, decides what we pay attention to
• what are the slave systems?

  phonological loop and visuo-spatial sketch pad
• capacity of central executive?

  limited
• where does data that enters the central executive come from?

  LTM and the senses
• what does the episodic buffer do?

  the backup store for the central executive, integrates STM and LTM info, stores verbal and visual info, maintains a sense of time sequencing (records in episodes), links STM to LTM
• when was the episodic buffer added to the WMM?

  2000
• duration of episodic buffer?

  temporary holding place before information is integrated
• how much info does the episodic buffer hold?

  4 chunks
• what does the phonological loop do?

  processes sound based info
• 2 sub components of the phonological loop?

  articulatory control process (inner voice) and phonological store (inner ear)
• what does the articulatory control process do?

  prepare speech, think in words, rehearse info verbally
• what does the phonological store do?

  stores sounds/ words we hear
• how is information received in the phonological loop?

  from the ears and acoustic info from the LTM
• what does the visuo-spatial sketch pad do?

  integrates visual and spatial information
• what does the visuo-spatial sketch pad allow us to do?

  picture things in your mind, have spatial information (distance)
• how is information received in the visuo-spatial sketch pad?

  from eyes and visual info in LTM
