Q

What is the PET and FMRI evaluation point?

A

take pictures of parts of the brain that are active when doing particular tasks. The prefrontal cortex is active when doing tasks in STM and hippocampus in LTM

Q

what did glanser and cunitz do?

A

gave participants list of 20 words, presented one at a time and askd them to recall.

17
Q

what did glanser and cunitz find out?

A

participants remembered words from the beginning (PRIMARY EFFECT) because the words were repeated so went into LTM. And remembered words from the end as they were in STM (recency effect)

18
Q

what is one weakness of the multistore model

A

validity

19
Q

explain how validity is a weakness

A

studies involved students studying psychology. People aged 18-21 have different memorys to those of other ages. Could be affected by demand characteristics

20
Q

why doesn’t validity support the study?

A

could be biased as it is does on psychology students
