Question 1

Working Memory Test

Answer 1

1. Corsi Blocks
2. Span Tasks,
3. Complex Span Tasks
4. Self-ordered Pointing

Question 2

Multi Store Model of Memory by Atkinson & Shiffrin

Answer 2

1. Sensory memory
   -> attention
2. STM <-> rehearsal
   -> transfer
   <- retrieve
3. LTM

Question 3

The original Working Memory of Baddeley

Answer 3

1. Visuospatial sketchpad
2. Phonological loop
3. Central executive

Question 4

Double dissociations between working memory and central executive

Answer 4

different Working Memory components are
independent
- memory problems in Alzheimer’s disease are
best explained by a central executive impairment

Question 5

The homuncular problem

Answer 5

There is a tiny person in human head does the experiencing and decision making
- however, central executive has no explanatory power

Question 6

The newer Working Memory of Baddeley

Answer 6

1. Visuospatial sketchpad
2. Phonological loop
3. Central executive
4. Episodic buffer

Question 7

brain areas WM impairment

Answer 7

left perisylvian lesions

Question 8

McCabe Effect

Answer 8

• During complex reading span task
• refresh the words that you are trying to remember by reactivating them during the short gap between reading sentences
• activating the link between the word in working memory, and its representation in LTM.
• It is this linking to LTM that produces the better recall of the words after a delay

Question 9

brain areas visuospatial WM impairment

Answer 9

errors on self-ordered pointing
- frontal lobes
- right temporal lobe
- hippocampus

Question 10

Visuospatial working memory test

Answer 10

Corsi Blocks Tapping Task
- forward
- backward

Question 11

phonological working memory test

Answer 11

Digit Span
- forward
- backward

Question 12

ELD case

Answer 12

right hemisphere stroke
- visual memory impairment
- bad Corsi blocks and other visuospatial tests
- normal vision
- good phonological working memory
