MULTI STORE MODEL By Symren, Ellie and Indi
Atkinson & Shiffrin 1968 • It’s a structural model • It is an explanation of how memory processes work • Consists of SM, STM and LTM
SENSORY MEMORY • Composed of several stores, these are your 5 senses • Constantly receives information • Info. Only lasts for a brief period of time • If focussed on it enters the STM • :P
SHORT TERM MEMORY • Limited capacity and duration • Decay and displacement occur because of this • If maintenance rehearsal is done then it goes into LTM • Capacity is 7+or-2 (Miller) • Duration is 20 seconds if rehearsal is blocked • It prefers to be encoded acoustically
LONG TERM MEMORY • Potentially unlimited duration and capacity • Prefers to be encoded semantically • Bahrick Et Al study suggests that long term memory could last up to 48 years
