Cognitive psychology 3: The HM case study

Who was HM?

• Harry Moleskin

• Henry Mallison

• Harry Morrison

• Henry Molaison

Why did HM have brain surgery?

• To treat his memory problems

• To treat his severe epilepsy

• To treat his anger management problems

• To learn about the parts of the brain involved in memory

Who performed the surgery?

• Dr Scoville

• Dr Miller

• Dr Milner

• Dr Shiffrin

What was removed from HM's brain during the surgery?

• his amygdala (in both temporal lobes)

• his frontal cortex

• his hippocampus (in both temporal lobes)

• his hypothalamus (in both temporal lobes)

HM had severe anterograde amnesia after the surgery. What does this mean?

• He could not use his short-term memory after the operation

• He could not make any new long-term memories after the operation

• He could not make any new procedural memories after the operation

• He could not remember who he was after the operation

After the operation ...

• HM's short-term memory (STM) was relatively intact

• HM's long-term memory for before the age of 16 was intact

• HM could not move information from short-term memory (STM) to long-term memory (LTM)

• HM could not remember who he was

What part of the brain is involved in transferring information from short-term memory (STM) to long-term memory (LTM)?

• The hypothalamus

• The hippocampus

• The amygdala

• The limbic system

Who conducted the mirror-drawing task with HM?

• Dr Scoville

• Dr Milner

• Dr Miller

• Dr Shiffrin

What does HM's performance on the mirror-drawing task tell us about memory?

• We are able to learn new motor skills even if we are not consciously aware of this

• Some tasks are impossible to get better at

• Memory does not just consist of declarative memory

• Memory also consists of procedural memory

Which model(s) of memory does the HM case study support?

• The multi-store model

• The working memory model

• Explanations of long-term memory

• The theory of reconstructive memory (including schema theory)
