Working memory model

Question 1

What is the working memory model (WMM)

Answer 1

Baddley and Hitch
STM is too simple in MSM
Dual task performance - 2 tasks using same component decreases performance for both tasks

Question 2

What does the central executive do

Answer 2

Coordinates STM activity/which component requires more attention
Delegates info to other components

Decision making
Reasoning
Problem solving

Question 3

What does the phonological loop do

Answer 3

Auditory info
Made up of phonological store and articulatory process

Phonological store - Holds words heard for 1-2s
Articulatory process - Holds words heard or seen/ rehearses them for maintenance

Question 4

What does the visuo spatial sketchpad do

Answer 4

Deals with/stores visual and spatial info
Mental planning
Made up of Inner scribe and Visual cache

Visual cache - Stores visual info
Inner scribe - Spatial relations/awareness

Question 5

What does the episodic buffer do

Answer 5

Collects all info and puts it in 1 event

Passes event to LTM

Question 6

Evaluate Baddeley and Hitch’s WMM

Answer 6

Patient EVR - Cerebellum removed - Good reasoning tasks/poor decision making - questions CE

Episodic buffer is too simple

Shallice and Warrington - Patient KF - Info can be encoded acoustically/visually

Nomothetic vs ideographic
