- MULTI-STORE MODEL
- HOW IT WORKS
- Richard Atkinson & Richard Shiffrin (1968)
- STM, LTM and sensory memory (SM)
- SM is eyes, ears, nose etc & corresponding areas of brain
- SM always receiving info
- receives no attention so remains in SM for v. little time
- attention focused on area of SM = moves to STM
- info in STM will decay quickly with no rehearsal
- also disappears if displaced (limited capacity)
- further rehearsal (elaborative) = transfer from STM to LTM
- STRENGTHS
- strong evidence of 3 qualitatively diff. stores
- provides account of memory in terms of structure and process
- clear predictions about memory so can be tested by psychologists
- WEAKNESSES
- oversimplifies memory structure and process
- STM & LTM are not unitary stores
- (non-unitary STM) KF suffered brain damage - probs with verbal info but normal visuall info
- patients with amnesia - can damage parts of LTM
- Schahter suggested 4 LT stores
- episodic - mem from yesterday/film you saw last week
- procedural - riding a bike/learning to read
- semantic - knowledge about world e.g. words
- perceptual-representation system - e.g ability to recognise _O_O_GA_ as TOBOGGAN
- rehearsal vs. processing
- not only maintenance rehearsal which transfers info from STM to LTM
- deeper processing leads to enhanced memory
- elaborative rehearsal (deeper/semantic analysis)
- separation of STM & LTM?
- Logie (1999) - STM relies on LTM so cannot come first
- need LTM to form meaningul 'chunks'
- Ruchkin et al. (2003) - STM is part of LTM which can be activated at any given time
- Logie (1999) - STM relies on LTM so cannot come first
