Working Memory Model

Question 1

AO1 points for the central executive

Answer 1

allocates slave systems
Coding - flexible
Capacity - limited

Question 2

AO1 points for the phonological loop

Answer 2

Deals with auditory information and preserves word order
Contains the articulatory process and the phonological store
Coding - acoustic
Duration - 2 seconds

Question 3

AO1 points for the Episodic Buffer

Answer 3

Integrates visual and spatial information
Coding - flexible
Capacity - 4 chunks

Question 4

AO1 points for the Visuo Spatial Sketchpad

Answer 4

Stores visual and spatial information
Loggie subdivided it into:
Visual Cache and the Inner Scribe
Capacity 3-4 objects/chunks

Question 5

What are advantages for the working memory model

Answer 5

KF
KF could recall words that he read but he could not recall words that were read to him. this showed that the visuo sketch pad was intact but the phonological loop was damaged because he could not recall words that were read to him (inner ear) and the phonological loop preserves word order. this shows that the phonological loop and the visuo sketch pad are distinct stores
Dual task support for the visuo spatial sketchpad
The dual-task technique involves asking participants to perform two tasks at the same time—one relying on the phonological loop and another on the visuospatial sketchpad.
dual task experiment where ppts had to track moving lights and also describe the angle of the letter F. performance was higher when the tasks were not using the same processing. this also shows that the phonlogical loop and the visuo sktech pad are seperate stores
Support from brain scanning studies

Question 6

What are disadvantages for the working memory model

Answer 6

lacks clarity over the central executive
reduces its usefulness in practical applications,
vagueness makes the central executive difficult to test experimentally, meaning there is limited empirical evidence to support its existence compared to other components like the phonological loop.

KFs thing is unique/rare case
it’s difficult to generalise his findings to the wider population.
This means the model’s evidence base is limited — it relies too heavily on rare, atypical cases rather than large-scale, controlled experiments. As a result, the validity of the Working Memory Model is weakened.

Question 7

what happened to KF

Answer 7

KF could recall words he read but he could not recall words that were read to him. this shows that the visuo spatial sketch pad is intact but the phonological loop is damaged and its function is to preserve word order so it shows its been damaged so it shows that the visuo sketch pad and the phonological loop are distinct stores

Question 8

what was the dual task

Answer 8

Baddelys experiment was where ppts had to track moving lights and also describe the position of the letter “F”. performance was higher when the tasks were not using the same processing
