  • Multi-store model (Atkinson & Shiffrin)
    • Sensory memory
      • information collected by senses (eyes, ears etc.)
      • Duration - information is retained for a very short period
      • Capacity - very large
      • Encoding - depends on sense organ involved i.e. visual for eyes, acoustic for ears
      • most information lost through decay
    • Short-term memory (STM)
      • temporary storage depot - storing information for brief periods of time
      • Duration - 18 to 30 seconds (Peterson & Peterson)
      • Encoding - acoustically (Conrad)
      • Capacity - 7+/-2 items of information (Miller)
    • Long-term memory (LTM)
      • holds a vast quantity of information for long periods of time
      • Duration - considerably longer than STM, can last almost a lifetime
      • Capacity - not possible to quantify exact amount, most psychologists agree it is unlimited
      • Encoding - semantically (Baddeley)
  • unitary stores
    • Short-term memory (STM)
      • temporary storage depot - storing information for brief periods of time
      • Duration - 18 to 30 seconds (Peterson & Peterson)
      • Encoding - acoustically (Conrad)
      • Capacity - 7+/-2 items of information (Miller)
    • Long-term memory (LTM)
      • holds a vast quantity of information for long periods of time
      • Duration - considerably longer than STM, can last almost a lifetime
      • Capacity - not possible to quantify exact amount, most psychologists agree it is unlimited
      • Encoding - semantically (Baddeley)
  • rehearsal is needed to pass information from STM to LTM
