  • working memory model
    • phonological loop
      • stores verbal info
        • baddley et al. participants were given a tracking task at the same time they had to either decribe angles along the way or perform a verbal task
          • "f" study
          • they found it was harder to track and decribe the angles because it was using the same slave sytem and tok up the capacity but travking and performing a verbal task was much easier because it used 2 componemts supporting the thoery of the phonological loop and the visual spatial sketchpad.
      • artculary loop is reahersal in stm. the word length effect study supports this idea
        • harder to remeber longer words than shorter words because the longer words did not fit into the capacity of the articulary loop.
        • maintains info in the stm if reahersed.
    • central executive
      • low capacity and duration.
      • drive the system and decides how the attention is divided
    • visual spatial sketchpad
      • stores visual and spatial information
      • baddley et al. participants were given a tracking task at the same time they had to either decribe angles along the way or perform a verbal task
        • "f" study
        • they found it was harder to track and decribe the angles because it was using the same slave sytem and tok up the capacity but travking and performing a verbal task was much easier because it used 2 componemts supporting the thoery of the phonological loop and the visual spatial sketchpad.
    • episodic buffer
      • low capacity and duration
      • central storage space for acoustic and visual info but for only 1-2 seconds
      • baddley(2000) added the episodic buffer because the model needed a genral store
      • intergrates info from all slave systems
    • strengths
      • explains real life studies such as kf
        • case study of kf supports the fact of diffrent stores as he could remeber visual stuff but not acoustic.
          • case study cannot be genralised to everyone
      • a lot of supporting research
      • much more detailed than the MSM.
      • used to diagnose patients.
      • case study of kf supports the fact of diffrent stores as he could remeber visual stuff but not acoustic.
        • case study cannot be genralised to everyone
    • weaknesses
      • the central executive is not supported with much research therefore is too simplified and unclear of it's purpose.
