types of long term memory ao3

Question 1

strength for tyoes of ltm - clinical ev PEEL

Answer 1

P; brain damged patients with amnesia can be used to prove types of ltm
E; HM and Clive wearing but HM still had functioning semantic mem eg concept of dog but had impaired episodic mem - couldnt remember stroking it
CW was a musicioan - his procedural mem was intact - he was still able to play piano but couldn’t remember learning how to (episodic)
futhermore hm still had intact procedural - could trace a star after mamy trials - didnt have intact epsisodic - didnt have mem of doing trisls
L: both pateints support idea of sep stores of ltm
ltm cannot be unitary as if it was patients wouldnt be able to remember anything long term but they could - implying their has to be diff types of ltm

e; lack of control varbiables in hm/cw studies - theyre injuries were unexpected and reseacrher cannot control what happned to individual b4 injury
e; thus researcher has no knowlege on their mem b4 damgage was done so we cannot judge how bad the mem got after accidnet
L: this lack of control limits what clinical studoes can tell us ab difd tyoes of ltm
