Q

Which 3 brain areas are important for short-term visual memory?

A
  1. Intraparietal sulcus
  2. Inferior occipital areas
  3. Medial frontal brain areas
17
Q

How is the intraparietal sulcus important in short-term visual memory?

A

Responsible for transient and limited storage of visuo-spatial info

18
Q

How are the inferior occipital areas important for short-term visual memory?

A

Involved in visual processing

19
Q

How are the medial frontal brain areas important for short-term visual memory?

A

Important for monitoring tasks

20
Q

How is verbal working memory investigated in humans?

A

A PET study investigating the articulatory loop

21
Q

What design was used to investigate the articulatory loop?

A

Cognitive subtraction design

22
Q

What does the phonological/articulatory loop include?

A

Storage and rehearsal

23
Q

What does rhyming judgement include?

A

Rehearsal

24
Q

What is common in both the articulatory loop and rhyming judgement?

A

Rehearsal

25
Q

What was found about Broca’s area in studying human verbal working memory?

A

It is involved in rehearsal

26
Q

What was found about the supramarginal gyrus from studying human verbal working memory?

A

Involved in storage

27
Q

How was the central executive studied?

A

Wisconsin card-sorting task

28
Q

What did the Wisconsin card-sorting task reveal about the central executive store?

A

It is involved in chunking

29
Q

Where was neural activity observed in the Wisconsin card-sorting task?

A

Occipital cortex, superior parietal lobule, prefrontal cortex

30
Q

How did the Wisconsin card-sorting task suggest executive working memory operations?

A

PFC neural activity correlates with task difficulty

31
Q

How was chunking demonstrated with a cognitive subtraction design?

A

Memorisation of structured patterns

32
Q

What demonstrated that the PFC was involved in chunking?

A

PFC is more active in memorised structured patterns

33
Q

What does working memory involve?

A

Retaining, refreshing, and manipulating info

34
Q

What does working memory allow?

A

Complex and adaptive behaviour

35
Q

How are working memory functions supported?

A

By a distributed frontoparietal network

36
Q

How are parietal regions demonstrated to be involved in STM?

A

Have a limited storage capacity

37
Q

How are frontal regions demonstrated to be involved in the central executive?

A

Involved in manipulations

38
Q

How are working memory and attention demonstrated to be strongly linked?

A

Dual-task interference makes working memory operations harder
