Multi-store model (MSM) – how info flows through memory system
Retrieval – transferring info from LTM to STM to recall.
Strength Weakness
STM & LTM are different Oversimplified - More than 1 STM
- HM has normal STM but cannot create new - KF can recall info read himself but not info
LTM read aloud.
Brain scans show different activation of brain - Case studies lack mundane realism
doing STM (prefrontal cortex) vs LTM Artificial stimuli - ↓mundane realism.

dual performance in one area are unable to be done effectively. (2 verbal).
