Support for The Multi-Store Model Flashcards
The Primacy Effect: research
research shows that participants are able to recall the first few items on a list better than those from the middle
The Primacy Effect: explains
the multi-store model explains this because earlier items will have been rehearsed better and transferred to LTM
The Primacy Effect: prevented
if rehearsal is prevented by an interference task, the effect disappears
The Recency Effect: Last
participants also tend to remember the last few items better than those from the middle of the list
The Recency Effect: STM
as STM has a capacity of around 7 items, the words in the middle of the list , if not rehearsed, are displaced from STM by the last few words heard
The Recency Effect: Last words
these last words are still in short term memory at the end of the experiment and can be recalled
Korsakoff Syndrome: What is it?
amnesia that’s mostly caused by chronic alcoholism
Korsakoff Syndrome: STM
they can recall the last items in a list, suggesting an unaffected STM
Korsakoff Syndrome: LTM
their LTM is very poor
Korsakoff Syndrome: Separate Stores
this supports the model by showing that STM and LTM are separate stores
Milner et al: Date
1957
Milner et al: what did they do?
carried out a case study into a patient called HM who had suffered from severe and frequent epilepsy
Milner et al: where were the seizures based?
in the hippocampus
Milner et al: surgery
doctors decided to surgically remove the hippocampus. this reduced his epilepsy but caused memory loss
Milner et al: STM
he could still form STM but was unable to form new LTM
