What are the strengths of the multi-store model?
There is evidence for separate stores in brain damaged patients, it explains the primary and recency effect, and it's supported by differences in capacity, duration and encoding. PET & MRI scans. Glanzer & Cunitz. Produces testable predictions.

What are the weaknesses of the multi-store model?
Too simple, having 1 STM and LTM has been disproved: amnesia patients suggest there are 2 LTMs,1 for declarative and 1 for procedural knowledge, KF had difficulty with verbal STM information not visual which suggests STM is not 1 store, flashbulb.

What research evidence supports the MSM, showing the existence of STM and LTM as separate stores?
Beardsley used brain scanning and found that the prefrontal cortex is active during STM but not LTM tasks. Squire et al. also used brain scanning and found the hippocampus is active when LTM is engaged, showing that different areas are active.

How does the case study of HM support the MSM?
His hippocampi were removed which led to an inability to transfer STM to LTM, but he could remember things from before the operation, showing there's a distinction between short and long term memories.
4 of 9
What has research shown that the LTM can be subdivided into?
Different kinds of memory.
5 of 9
Who was the elaboration of the MSM supported by?
Craik and Tulving.
6 of 9
What did Craik and Tulving do in their study?
Participants were given task that involved shallow or deep processing.
7 of 9
What did Craik and Tulving find, and what did it show?
The participants remembered more words involving deep processing, which shows that elaborative processing is key in memory
8 of 9
What did Ruchkin et al. find?
The the STM is not entirely separate from the LTM as participants' brain activity was different when they processed real or pseudo-words.
