- Words at the end were still in the STM, and the ones were in the middle were forgotten due to STM capacity (Miller).
- Glanzer & Cunitz (1966)
- Words were remembered more from the start of the list because they had been transferred by rehearsal to the long-term memory.
- Participants remembered more words on average from the and end.
- The primary effect (beginning) and recency effect(end).
- Participants were given a list of common words to memorize and then asked to recall as many as possible.
- To investigate whether STM & LTM are different memory stores.
- This is called the serial position effect.
- Glanzer & Cunitz (1966)
- It has little effect on STM but severely impairs the LTM.
- Korsakoff's syndrome
- Chronic alcoholics develop this syndrome which causes brain damage.
- This therefore suggests they are stored in different areas of the brain.
- Korsakoff's syndrome
- This left HM with severe anterograde amnesia- meaning he was unable to make any new memories.
- Milner at al (1966)'s Case Study on Epilepsy patient HM
- HM suffered from severe epilepsy, he underwent surgery which later went wrong damaging his hippocampus.
- He could not make any new episodic and semantic memories because his STM and LTM were not connected.
- They investigated anterograde amnesia by using numerous psychometric tests and experiments and observations.
- HM had the ability to learn motor skills- showing his procedural memories were intact stil
- Damage to the hippocampi destroy the LTM and leaves pateints in a world of memories lasting as long as their STM.
- Milner at al (1966)'s Case Study on Epilepsy patient HM
- Cases of brain damage like this support the distinction between the STM and LTM.
