Other than in brain damage our capasity is Unlimited



Long term memorys can last for a Lifetime

Multi-store model (MSM)

  • By Atkinson and Shiffrin (1968)
  • Used to explain how memory working


5 of 8

Evaluation of MSM


+ Cuntiz (1966) findings showed that the recency effect will come from the STM and the primary effect from the LTM


- It is too simple to explain the "extreamly complex" mind

- Rehersal cant be the ONLY way to transfer STM to LTM

Working Memory Model (WMM)

  • By Baddeley and Hitch (1974)
  • Adresses the weeknesses of the MSM

Evaluation of WMM

+ Baddeley (1993) proved that when counting windows on a house, you use your inner eye

+ Positiron Emisson Topography (PET) technology proves components of WMM

- Central exective is not clear enough for the most important role

- Richardson (1984) Proved that two tasks cannot be done at the same time
