Q

ltm encoding

A

semantically
bahrick et al

17
Q

the case of hm

A

underwent brain surgery to relieve his epilepsy
hippocampus removed from both sides of his brain
ltm was lost
performed well on immediate memory span , stm
SUPPORT stm and ltm diff stores

18
Q

strength
supporting evidence research

A

baddely found ;
stm mix up words that sound similar
ltm mix up words that mean similar
show stm = acoustic encoding
ltm = semantic encoding
show they are two different stores

19
Q

weakness
more than one type of stm

A

msm = stm unitary store
shall ice and warrington ; KF
Kf had amnesia
found his stm recall of digits when read out to him was poor
but much better when he could read the digits himself
- other stm store for non verbal sounds
unitary stm limits msm as there must be a stm to process visual info and another for auditory info , wmm includes these

20
Q

weakness
more than one type of rehearsal

A

only acknowledges maintenance rehearsal ie word lists
craik and Watkins found ;
describe two types of rehearsal
maintenance rehearsal , repetition stays in stm and elaborative rehearsal linking info to pre existing knowledge
- limitation of msm a another research finding can not be explained by the model

21
Q

weakness
more than one type of ltm

A

episodic
semantic
procedural
msm = ltm unitary store
