Study brain-damaged patient case studies in Pearson Edexcel A Level Psychology through HM, memory stores, usefulness, ethics, triangulation and generalisability.
The multi-store model of memory by Atkinson and Shiffrin (1968) includes short-term memory and long-term memory stores.
Explain two ways that the case study of Henry Molaison (HM) demonstrates the difference between short-term memory and long-term memory.

Credit up to two marks for accurate identification (AO1).
Credit up to two marks for justification/exemplification (AO3).
For example:
- HM had a functional STM but was unable to make new
long-term memories (1) which demonstrates that memory
has two distinct memory stores (1).
- He could recall events from before the operation on his
hippocampus but not any events that he experienced
afterwards (1) showing that memory stores may be
physically located in different regions of the brain (1).
Look for other reasonable marking points.
