The Case of HM (Milner et al. 1968)

The real name of HM was

• Henry Molaison

• Harold Milner

• Heston Minuchin

• Hector McMolaison

HM underwent brain surgery in 1953 to treat which condition?

• severe epilepsy

• brain tumour

• stroke

• parkinsons

HM's age when the underwent surgery....

• 21

• 25

• 27

• 37

HM's brain surgery remved large areas of the temporal lobe

• in both hemispheres (bilateral)

• from the left hemisphere only

• from the right hemisphere only

Surgeon William Scoville removed areas of HM's...

• frontal lobe

• temporal lobe

• parietal lobe

• occipital lobe

Following the surgery it was revealed that HM was no longer able to

• create new long term memories (anterograde amnesia)

• recall elements of his past (retrograde amnesia)

• learn new skills such as 'mirror drawing'

• have meaningful conversations with family or nursing staff

Although Henry could not learn new facts or remember events that had happened post surgery he was able to learn new skills skills such as mirror drawing and this suggests that which type of long term memory is not localised to the temporal lobe region

• procedural memory

• declarative memory

• episodic memory

• autobiographical

The case of HM can be used to support Multi-Store Memory Model because

• it shows there are different types of LTM

• it shows there are different types of STM

• it shows that STM and LTM are separate stores

• it shows rehearsal is necessary for information to be stored long term

The case of HM shows that STM and LTM are separate stores because

• his digit span was normal and he was able to follow a conversations and read a newspaper but he was not able to recall information from LTM

• his digit span was severely limited to only 2 items but he had no difficulties in recalling events from the past

• he was able to play the piano and sing as well as he did as a younger man but he could not recognise his wife.

The case of HM can be used to refute the idea that LTM is one unitary store because...

• HM could still play chess

• HM learned a new skill mirror drawing

• HM's verbal memory was weaker than his visual memory
