[Memory] Topic 3 The working memory model

Question 1

Who proposed the working memory model?

Answer 1

Baddeley and Hitch because they felt that the WMM was not just one store but multiple stores

Question 2

What does the central executive do?

Answer 2

Controls the WMM and directs attention to one of the three slave systems

Question 3

What is the Phonological loop?

Answer 3

The phonological loop deals with auditory information and contains the phonological store which holds the words you hear and the articulatory control process which allows for maintenance of acoustic information

Question 4

What is the Visio- Spatial sketchpad?

Answer 4

Used for the planning of spatial tasks, the VSS contains the visual cache which stores visual information and the inner scribe which deals with spatial- relationships and stores the arrangement of objects in the visual field

Question 5

When did Baddely add the Episodic buffer?

Answer 5

In 2000 Baddely added the episodic buffer which is a general store for both visual and acoustic information. The purpose of the episodic buffer is to interrogate information from the other 3 components and send information to the LTM

Question 6

Evaluation 1: A strength comes from Dual task studies

Answer 6

• Dual task studies
• Baddley and hitch found that participants were slower in dual task studies that involved both the central executive and articulatory loop, in comparison to a task which just required the articulatory loop
• This demonstrates the dual task performance effect and shows that the central executive is separate from the articulatory loop.
• This supports the idea of multiple components in STM and the idea of WMM
