Atkinson & Shiffrin's Multi store model of memory

- A system of stages which suggests information passes through a fixed sequence

SENSORY STORE

Information passes through here before decaying or passing into a short term memory store.
There are two kinds of sensory storage: echoic, associated with auditory information, and iconic, associated with vis

SHORT TERM MEMORY

Encoding: Acoustic (Baddeley 1966)
Duration: 18 seconds (Peterson & Peterson 1959)
Capacity: 7+-2 chunks (Miller, 1956)
REHEARSAL

Craik & Watkins (1973) determined there were two different types:

Maintanence keeps information in short term memory by for example repeating a word over and over
Elaborative needed to move information into long term memory since information is processed in terms of meaning

LONG TERM MEMORY

three types

procedural - skills
episodic - memories of events
semantic - facts

Encoding: Semantic - based on meaning (Baddeley 1966)
Duration: Unlimited (Bakrick, Bahrick & Wittinger 1975)
Capacity: Unlimited (Anohkin, 1973)

Limitations: Rehearsal doesn't always lead to storage.
Some things don't need to be rehearsed for us to remember them - e.g. smells.
