MULTI-STORE MODEL OF MEMORY STRENGTHS AO2
1 Support: Look at Peterson & Peterson & Bharicks experiments - support the idea of different stores for STM & LTM
2 Glanzer & Cunitz (Primacy & recency effect)
2.1 A: Find if there are different stores for STM & LTM
2.2 P: presented with a list of words (one at a time)
2.2.1 Condition 1: Recall words in serial order immediately after presentation
2.2.2 Condition 2: Given a distractor task & asked to count back in 3's for 30secs - then asked to recall words
2.3 F: Condition 1; found the expected serial curve
2.3.1 Condition 2; distractor task, disrupted the regency effect & the last words were not accurately recalled
2.4 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
3 Important contribution to understanding memory by stimulating research into different components
3.1 Supported by lab experiments which show different stores (sensory, STM, LTM) E.G. Glanzer & Cunitz
3.2 Most influential model built about information processing
4 Case studies who have suffered from brain damage
4.1 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)
4.1.1 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
4.1.1.1 Suggests different structures in STM & LTM & that the hippocampus plays an important role in making new memories
5 Evidence from PET and mRI scans supports the existence of two separate stores
5.1 Squire found that the hippocampus is active in LTM tasks & the pre-frontal cortex is active for STM
5.1.1 Physiological basis for the different stores
