working memory model

• components of wmm

  central executive:

  • identify and organise where information goes
  • capacity is limited
  • no specific coding

  phonological loop:

  • deals with auditory information and preserves word order (inner voice)
  • capacity is limited (2 seconds)
  • coding is auditory

  visuospatial sketch pad:

  • store visual and spatial information (inner eye)
  • capacity is limited (3-4 objects)
  • coding is visual

  episodic buffer:

  • general store for information
  • capacity is limited (4 chunks of information)
  • no specific coding
• working memory model

  • theory by Baddeley and Hitch.
  • believed that memory is not just one star but a number of different stores.
  • focused on STM only and believed it was not a singular store like LTM.
• EVALUATION - wmm

  • P: dual task performance studies support the sketchpad.
  • P: word length effect supports phonological loop.
  • N: lacks clarity over the central executive.
