    • AO1
      • By Atkinson and Shiffrin 1968
      • suggested the brain is made up of 3 stores
        • sensory memory store
          • all the sensory information is stored such as taste and smells
        • Short-term Memory
          • can hold 7 plus or minus 1 items, for about 30 seconds, if it is rehearsed it moves to the LTM, if not, it is lost
        • Long term memory
          • infite capacity and can remember from minutes to a life time
      • information has to be recalled from the LTM through the STM to produce the assosiated response
    • AO2
      • POSTIVE
        • the case of HM who had part of his temporal lobe removed to releave the symptoms of epilepsy. As a result, he was unable to make new memories. He had trouble recalling information 11 years prior but could remember before the age of 16. He could learn new motor skills
          • this suggests that the STM and the LTM are in differnt places and maybe even the LTM is broken down in the 2 or more parts
        • SYNTHE AND COSTALL 2003
          • found that mobiles stimulate the STM but not the LTM so they must be separate
      • NEGATIVE
          • found verbal tasks interfered with the ability to do sums, motor tasks didnt, so there may be more than one STM for different information
        • the case of FK
          • suggest material in STM is analysed for meaning not just sound-levels of processing may be better
        • HM
          • several separate LTMs as he had damage to one memory system but not others.
