Q

what is the duration of info being held in LTM

A

unlimited

18
Q

how is info able to be recalled

A

information retrieval from LTM into STM

19
Q

what case study supports the multi store model

A

Henry Molaison (HM)

20
Q

what did doctors do to HM

A

they removed both hippocampus within his brain - surgery for epilepsy

21
Q

what was HM unable to do after his surgery

A

he was unable to recall the operation, and could not remember speaking to someone an hour earlier

22
Q

what type of memory was still intact for HM

A

short term memory

23
Q

how does HM support the multi store model of memory

A

study of HM shows that LTM and STM are two distinct stores
