MULTI-STORE MODEL
OF MEMORY STRENGTHS AO2
- Support: Look at Peterson & Peterson &
Bharicks experiments - support the idea of
different stores for STM & LTM
- Glanzer & Cunitz
(Primacy & recency
effect)
- A: Find if there are different
stores for STM & LTM
- P: presented with a list of words
(one at a time)
- Condition 1: Recall
words in serial order
immediately after
presentation
- Condition 2: Given a distractor
task & asked to count back in 3's
for 30secs - then asked to recall
words
- Condition 1: Recall
words in serial order
immediately after
presentation
- F: Condition 1; found the expected serial curve
- Condition 2; distractor task, disrupted the regency
effect & the last words were not accurately recalled
- Condition 2; distractor task, disrupted the regency
effect & the last words were not accurately recalled
- C: Last words in the list had been
displaced by the distractor task from
the fragile STM, but the earlier
words were remembered cause they
had been rehearsed into LTM
- A: Find if there are different
stores for STM & LTM
- Important contribution to
understanding memory by stimulating research
into different components
- Supported by lab experiments
which show different stores
(sensory, STM, LTM) E.G. Glanzer
& Cunitz
- Most influential model built about
information processing
- Supported by lab experiments
which show different stores
(sensory, STM, LTM) E.G. Glanzer
& Cunitz
- Case studies who have suffered from brain damage
- E.G. H.M. hippocampus was taken out in surgery -
lost his ability to make new long term memories
but retained memories before surgery (same as
Clive Wearing)
- Could never remember the psychologists
& reread the same magazine BUT it did not
affect his STM as he still had a digit span of
6words
- Suggests different structures in STM & LTM & that
the hippocampus plays an important role in making
new memories

- Evidence from PET and mRI scans supports
the existence of two separate stores
- Squire found that the hippocampus is
active in LTM tasks & the pre-frontal
cortex is active for STM
- Physiological basis for the
different stores
