  • The Working Memory Model
    • 3 main components
      • Central Executive
        • based on attention
      • Phonological Loop
        • phonological store
          • "the inner ear"
          • used when trying to recall conversation or when listening to our own 'self talk'
        • articulatory control system
          • used for verbal rehearsal
        • many tasks use both parts of the phonological loop
      • Visuo-spatial Sketchpad (VSS)
        • "the minds eye"
        • used to visualise objects, plan routes or remember where the car is parked
    • Evaluation
      • Strengths
        • dual task technique
          • Untitled
    • Research Evidence
      • Dual Task Technique
        • Baddeley and Hitch (1976)
        • assumed that each slave system has limited capacity. So performance will deteriorate if an individual is asked to complete two tasks that use the same slave system. However if two tasks use different parts of the system, performance is unaffected.
          • e.g. trying to repeat a word (or recite a list of digits) whilst trying to read information, as both these task use the phonological loop, performance is expected to suffer
      • Word Length Effect
        • Baddeley (1975)
        • participants remember a greater number of short words than long words, this suggests that the time taken to pronounce words plays a key role in determining the capacity of STM
        • however the word length effect disappeared when the articulatory supression task was introduced by Baddeley eg repeating sounds such as 'lalala' while rehearsing
  • Baddeley and Hitch (1974) tried to replace the MSM, which they saw as limited and inaccurate

  • controls other parts of the model which are known as slave systems
    • the salve systems process different types of information
      • this allows different tasks to be completed at once if enough attention is available
  • "the inner voice"
