Multi-store Model

Multi-store Model

1. Developed by Atkinson and Shiffrin in 1968

2. Capacity

3. Coding

   • LTM
     • Semantic
     • Baddeley (1966): Four trials, for ps, to learn the order of a list of words. Then used 20-minute delay asked ps to recall as many words as possible in order. Compared 5th score with 4th score 20 minutes earlier to see how much they had forgotten. Ps’ STM was helping their LTM out, working together. He carried out a second test. Ps performed an interference task after. Worked - cancelled out STM - ps were only using LTM to recall.
   • STM
     • Conrad (1964): Found most recall errors could be due to sound of letter. Few errors were made if sounds were very different. Suggests STM codes acoustically
     • Mainly acoustic, but can be recoded if visual and semantic
   • Acoustically, visually or semantically
   • How sensory input is transferred into a form, allowing it to be processed by the memory system
   • Sensory register
     • Crowder 1993: Found that the SR only retains information in the iconic store for a few milliseconds, and two-three seconds in the echoic store. Supports idea of different memory stores and their duration.
