  • Multi-Store Model of Memory
    • Sensory Memory (SM)
      • Gathers info from senses (eyes, ears, nose, fingers etc)
        • Majority of info gets no attention
          • Modality specific encoding (echoic for sound etc)
            • Transfers to the STM if it cathces our attention
      • Very breif time period (250ms)
      • Small capacity (4-5 items)-Sperling
        • Very breif time period (250ms)
      • Short Term Memory (STM)
        • Hold information currently being used
          • Info fragile from phonetic format in SM
        • A&S blieved:
          • Limited capacity=7 chunks (miller)
          • limited duration (30 seconds)-Peterson&peterson & Brown
        • usually forgotten by decay
        • (MAINTENANCE) rehearsal --> LTM
        • Long Term Memory (LTM)
          • Unlimited capacity and duration (Bahrick)
            • Mainly held by meaning (semantically encoded, Baddeley)
              • The more info is rehearsed the longer/better it would be rememebered
    • Atkinson & Shiffrin (1968)
      • One of the first models of memory and very influencial-led to WMM and LOP
        • Linear structure as it consists of 3 structural stores in one direction
          • due to processes such as attentional and rehersal
    • Short Term Memory (STM)
      • Hold information currently being used
        • Info fragile from phonetic format in SM
      • A&S blieved:
        • Limited capacity=7 chunks (miller)
        • limited duration (30 seconds)-Peterson&peterson & Brown
      • usually forgotten by decay
      • (MAINTENANCE) rehearsal --> LTM
      • Long Term Memory (LTM)
        • Unlimited capacity and duration (Bahrick)
          • Mainly held by meaning (semantically encoded, Baddeley)
            • The more info is rehearsed the longer/better it would be rememebered
    • Empirical support
      • Free recall-Glanzer and Cunitz's (1966) serial positioning effect
      • MRI Brain scan evidence
    • Case Study
      • HM
      • KF
      • CHALLENGE- Clive Wearing
    • Reductionist
      • Linear processing
      • Relies on rehearsal
      • Not unitary stores
        • WMM
      • Not accurate representation of stores
    • Methodological issues
      • Highly controlled environment
      • Lacks mundane realism
      • Lack of ecological validity
  • Linear structure as it consists of 3 structural stores in one direction
    • due to processes such as attentional and rehersal
