  • The Multi-store Model of Memory
    • Outline
      • Short term memory
        • Capacity: 7 +/- 2 items
          • Study: Miller (1956)
        • Duration: 18-30 seconds
          • Study: Peterson & Peterson (1959)
        • Encoding: accoustic
          • Study: Conrad (1964)
      • Sensory memory
        • Capacity: very little
        • Duration: 0.25 seconds
        • Encoding: sensory
      • Long term memory
        • Capacity: unlimited
        • Duration: up to a lifetime
          • Study: Bahrick et al (1975)
        • Encoding: semantic
          • Study: Baddeley (1966)
    • Evaluation
      • Advantages
        • There is a general agreement that there is a STM/LTM distinction
        • Useful model based on empirical evidence
          • Many subsequent theories derived from it
      • Disadvantages
        • Reductionist:the model is over simplified
          • Doesn't  consider more complex processes
        • Research shows that rehearsal is not essential for the transferral of information from STM to LTM.
          • E.g. we may remember things if they are funny or meaningful
          • Rehearsal can often be a very bad strategy for memorising information
            • Britain  (late 1970s): the BBC introduced new radio frequencies. Despite the policy of saturation (most people heard the information literally hundreds of times) they still did not retain the information.
              • Suggests that passive rehearsal was not adequate to transfer information into the LTM.
    • It is an attempt to explain how information flows from one storage system to another.
