11: The Remembering Brain 2

Question 1

what are the 3 components of the working memory model?

Answer 1

visuospatial sketchpad
episodic buffer
phonological loop

Question 2

what are the 2 components of the phonological loop & their corresponding areas in the brain?

Answer 2

Phonological store = left supramarginal gyrus
Rehearsal/Manupulation system = Broca’s area

Question 3

how do delayed recognition tasks teach us about the working memory model?

Answer 3

short term memory stores require sustained activity in posterior areas that represent the specific brain activity (eg fusiform face area for faces)

Question 4

what component of memory is the PFC related to?

Answer 4

working memory

Question 5

what happens to activity in the neurons during & after the required response is given in a working memory task?

Answer 5

during = activity sustained
after = it diminishes

Question 6

how does working memory load influence activity in the delay period between learning & test

Answer 6

higher memory load = greater activity

Question 7

what are the differning roles of the vento- & dorso- lateral PFC in the working memory?

Answer 7

DLPFC = manipulation & monitoring
VLPFC = maintain activity and retrieve information
(Petrides’ theory of Working Memory)

Question 8

where in the brain is the central executive in Baddeley’s working memory model?

Answer 8

prefrontal cortex

Question 9

what are the specialisation of the left & right PFC for encoding?

Answer 9

Encoding of words or semantic materials= left PFC
Encoding of spatial information or faces = right PFC

Question 10

define: source monitoring

Answer 10

the process of determining the origins of one’s memories, knowledge, or beliefs (PFC)
