Multi-store model.

Incoming sensory stimuli  -> sensory memory (register) -> short term memory -> long term memory                            

This shows the idea of information processing.
The multi-store model proposes that memory consists of three stories a sensory store, short term store and long term store.  Information form out environment initially goes into the sensory memory , if paid enough attention to, or you think about it the information then gets passed to your short term memory. The short term memory has a finite space and duration but if information is rehearsed or processed further information can be transfused to the long term memory and stay there forever.
Peterson and Peterson (1959) aim was to test duration of short term memory when rehearsed is prevented for differing lengths of time – findings were that as the delay between the hearing the trigum and reporting increased recalling. When rehearsal is prevented items in the short term memory are lost quickly (aprox 28secs).
HM- sustained bad damage to his long-term memory but could still revive it in his short implying that the two must be separate.
Baddeley and Hitch (1974) proposed a more comprehensive version of short term memory called the wishing memory involving different systems that deal with different sounds images etc.
Atkinson and Shiffin 1968 view on the STM is wrong and the evidence for FK suggests that the stm is analysed for meaning and not just for sound.

+ evidence to support it from other studies such as Glancser and Cunitz (1966)
+case studies such as Clive Wearing support the model and help support it with scientific evidence of the hippocampus may be an area of the short term memory.

Levels of processing

Craik and lockhart – how the memory operates

Structural processing – what things look like                                                                        shallowest
Phonetic processing-  what things sound like
Semantic processing- what things mean                                                                                                deepest

there is experimental evidence – Craik and Tulving (1975) – analysing words.
