Working memory model Flashcards
This covers the types of memories, parts, strengths and weaknesses of the WMM.
1
Q
What are the 3 LTM stores?
A
- Episodic memory
- Semantic memory
- Procedural memory
2
Q
What is episodic memory?
A
Memories are of:
- events
- people and places
- are time stamped
- Memories are easily and quickly accessed with conscious effort
3
Q
What is semantic memory?
A
- knowledge of the world, facts, things and their meanings.
- IS NOT time stamped
- Memories may be easily and quickly accessed with conscious effort
4
Q
What is procedural memory?
A
- actions and skills
- Memories received without conscious effort
- not stamped
e. g. driving
5
Q
What does the Central Executive control?
A
- It processes information from the senses and LTM
- It has a limited capacity
- It allocates one of the slave systems to a task
6
Q
What’s the two parts of the phonological loop?
A
- Phonological store/ “inner ear”
- Articulatory control systems/ inner voice
7
Q
What’s the function of phonological store/ “inner ear”?
A
- Holds words that have been heard
- Uses a sound based code to store information - – decays after 2 seconds unless rehearsed by articulatory control system
8
Q
What’s the function of articulatory control systems/ inner voice?
A
- Rehearses information
- capacity of about 2 seconds
9
Q
What are the two parts of the visuo-spatial sketchpad?
A
- Visual cache
- Inner scribe
10
Q
What’s the function of visual cache?
A
- Stores information such as form and colour
11
Q
What’s the function of inner scribe?
A
- Deals with spatial relations
- Stores information about where items are in the visual field
12
Q
What is the role of the episodic buffer?
A
- Temporarily stores information
- binds together all of the information from the other components
- prepares memories for storage in LTM.
13
Q
What are the strengths of the working memory model?
A
- fits with everyday experience
- Baddeley: mentally counting the number of windows in your house demonstrates the operations of working memory.
- KF suffered brain damage, his verbal information recall was poor. But visual wasn’t. - supports separation of the phonological loop.
14
Q
What is a limitation of the working memory model?
A
- The functions of the central executive are vague and difficult to test.
- How the capacity of the central executive can be measured independently is unclear.
