HM 1957? background
Hm was a man who was ran over by a bicycle and and his hippocampus removed in an attempt to cure his epilepsy
Hm could not create new LTMs but he could access old LTMs and he could create new STMs
This proved that LTM and STM were separate stores of memory

HM and miss Milner 1962-72
Milner asked hm to complete an IQ test, a maze drawing activity and a mirror trace a star activity
Hm had above average IQ
after 252 attempts there was no improvment on the maze task (after 30 sec forgot the correct way out)
He showed improvement on the star task
This improvement on the mirror star task shows that proceedual memory in HM was undamaged whereas new episodic memories such as the correct way out of the Maze were very damaged
This result supports Tulving’s LTM Theory as it proves the distinct separation between episodic + semantic memories and procedural memories

Bus supporting Tulving’s LTM Theory as it shows that LTM consists of different substores
