  • MULTI-STORE MEMORY MODEL(ATKINSON & SHIFFIN (1968)
    • SENSORY MEMORY this store gathers infomation from our senses and recieves a wide variety of information
      • not a lot of info gets attention, data is in the sensory store for a very breif period of time and is held in the form in which it is recieved. if info is attended to it moves to the SORT TERM MEMORY
        • Echoic = sound
        • Iconic -visual
      • SPERLING tested iconic memory by flashing groups of letters then asked p's to recall
        • SUPPOURTS as couldn't renember much showing info is forgotten quickly from SM
    • SHORT TERM MEMORY information is attended to once it reaches here.Information is fragile and is usually forgotten though a process of decay
      • ATKINSON AND SHIFFRIN believed it had a limited capacity of about 7 chunks, and a duration of up to 30 seconds
      • information was held in a phonetic format so it had to be translated from the format that it was recieved in
      • in order to reach the LONG TERM it needs to be rehearsed, MAINTENANCE REHERSAL
