• Who made the Multi Store Memory Model?

  (Atkinson & Shiffron, 1978)
• Long term memory:

  Unlimited memory store. If STM’s are rehearsed, they will be encoded into LTM.
• Duration of LTM:

  potentially a permanent memory store For info that has been rehearsed over a long period of time.

  May last up to a lifetime.
• Capacity of LTM:

  Unlimited.

  we store everything we have learned in it.

  If you forget info in LTM, it’s may still be there you just don’t have the right cues.
• Encoding of LTM:

  Mainly semantic (Based on meaning)

  Baddeley (1966b) found that mistakes were make in recalling words from LTM but tended to involve substituting words with the same meaning.
