The Working Memory Model^

Question 1

Whats in the Central Executive

Answer 1

Visiospacial Sketchpad
- visual catche
- inner scribe
Episodic Buffer
Phonological Loop
- articulatory process
- phonological store

Question 2

Baddeley & Hitch

Answer 2

Critique of MSM as its too simplistic

STM has more than one store - dual task performance
: doing 2 tasks with same sense is Worse than doing them separately
- no interference for a visual and auditory task
: performance dont change
Suggest separate stores for visual and auditory info

Question 3

Central Executive

Answer 3

direct attention to specific tasks for corresponding store
- depend on brain function require to do the task
Limited capacity
- cant do many things at once

Question 4

Visuospatial Sketchpad

Answer 4

stores visual or spatial info
Baddeley
- limited capacity (3 or 4 objects)
Logie
- subdivided it
- visual cache: visual data
- inner scribe: arrangement of object

Question 5

Phonological Loop

Answer 5

limited capasity
auditory info, preserves the order the info arrived
Baddeley - divided it
- phonological store - heard words (inner ear)
- articulatory process - maintenance rehearsal (inner voice)

Question 6

Episodic Buffer

Answer 6

Baddeley
- combine central executive and sequence of events
- added it to WMM as it needs general store for both visual spatial and verbal info
Limited capacity
- 4 chunks send to LTM

Question 7

Dual Task Performance

Answer 7

Baddeley

Simultaneosly perform visual and verbal tasks- proves different components to STM- performance worse when same store used twice at the same time
: showes STM limited capacity

Question 8

Nature of Central Executive

Answer 8

lack of clarity over the role of the central executive
Baddeley
- most important, least understood
CE needs to be more clearly defined, than just be a place for attention and sending info to subcomponents
lack of clarity challenges the validity of the model

Question 9

Clinical Evidence

Answer 9

Shallice & Warrington- KF with brain damage
: STM for auditory info was damaged as as PL impaired
: visual abilities remained
- support existence of separate stores for visual/ auditory

Question 10

Research Support

Answer 10

HM/ Clive Wearing
neurosurgery led to damage of their episodic memories
semantic and procedural remained
proof of diff LTM stores

Question 11

Validity of the Model

Answer 11

studies that test the model use artificial materials and tasks not reflective of real life
- conducted in highly controlled lab settings
