Theories of memory: The working memory model - Baddeley + Hitch

Question 1

What is the WMM supposedly used for?

Answer 1

Used when working on complex tasks where info needs to be stored as u go along

Question 2

What are the 3 components of the WMM?

Answer 2

Central executive, and the 2 slave systems - visuospatial sketchpad, and phonological loop.

Episodic buffer added as 3rd slave system at later date

Question 3

What is the function of the central executive?

Answer 3

Coordinates + manages other components of WMM. Pays attention to incoming data, makes decisions on this data, and allocates tasks to slave system (decides what we pay attention to + what part of system deals with it)

Question 4

What is the encoding and capacity of central executive?

Answer 4

Encoding = Modality free
Capacity = Limited

Question 5

What are the 3 slave systems?

Answer 5

Phonological loop, visuospatial sketchpad, and episodic buffer added

Question 6

What is the phonological loop split into?

Answer 6

1. Phonological store = inner ear
2. Articulatory control process = inner voice

Question 7

What is the function of the phonological STORE?

Answer 7

Inner ear - stores words u hear, and only deals with acoustically encoded info

Question 8

What is the duration + capacity of the phonological STORE?

Answer 8

Duration = 1.5 - 2 seconds
Capacity = Holds the amount of info u can say in 1.5 - 2 seconds

Question 9

What is the function of the articulatory control process?

Answer 9

Inner voice - Rehearses verbal sounds + holds info that we want to maintain or say. Allows maintenance rehearsal

Question 10

What is the duration + capacity of the articulatory control process?

Answer 10

Duration = 2 seconds
Capacity = 2 seconds worth of what u can say

Question 11

What is the function of the visuospatial sketchpad (VSS)?

Answer 11

Stores visual + spatial info (can visualise where things are). Known as the inner eye (what things look like in ur mind)

Question 12

What is the capacity of the VSS?

Answer 12

Limited, 3-4 objects

Question 13

What did Logie (1995) subdivide the VSS into?

Answer 13

• Visual cache = Stores visual data e.g. images
• Inner scribe = Records arrangement of objects in a room. Allows u to rehearse visual/spatial info to maintain in visual cache

Question 14

Why was the episodic buffer added to the VSS?

Answer 14

To add detail on how the phonological loop + visuospatial sketchpad interact.

ONLY TALK ABT EPISODIC BUFFER IN AO3

Question 15

What is the function of the episodic buffer?

Answer 15

Temp store for info, integrates visual, spatial, and verbal info processed by other components. Maintains a sense of time sequencing

Question 16

What is the capacity of the episodic buffer?

Answer 16

Limited capacity
