  • Working Memory Model
    • Baddeley & Hitch
    • 3 stores
      • Central executive
        • In charge of attention
      • The Articulatory Phonological Loop
        • Stores audio information e.g speeches or conversations
          • Has a limited capacity (7+/-2) and a limited duration
            • In charge of attention
            • Stores Visual and Spatial information, e.g. a picture (visual) or the route you take to school (spatial)
      • The Visuo-Spatial Sketchpad
        • Stores Visual and Spatial information, e.g. a picture (visual) or the route you take to school (spatial)
    • For STM only
    • The process
      • Information from our SM enters the STM by going into the  central executive.
        • We then pay attention to the information through rehearsal
          • the information then passes into one of the two 'slave drives' the PAL or the VSS depending on the type of information it is
            • When the information is in one of the 2 slave drives we either pay attention to it through rehearsal so it enters our LTM or the information decays because we haven't paid enough attention to it.
    • Evidence supporting the WMM
      • Shallice & Warrington 1974
        • Case study of KF a brain damage patient who had an impaired STM
          • KF couldn't immediately recall verbal information but could recall visual information
            • This shows that there has to be separate stores for visual and verbal information
      • Baddeley & Hitch
        • Interference task
          • Participants were asked to take part in a reasoning task at the same time as saying 6 digits aloud.
            • They found that few errors were made on either task but there was a difference in the speed that the reasoning task was done at
              • This proves that there is more than one store and that different stores can be used in conjunction with one another
    • Limitations od the WMM
      • Some scientist feel that the idea of the central executive is too vague
        • all we know is that the CE is in charge of attention but not how it works.
  • When the information is in one of the 2 slave drives we either pay attention to it through rehearsal so it enters our LTM or the information decays because we haven't paid enough attention to it.
