What are the three sub components of the working memory model?
- The phonological loop
- The visuospatial sketchpad
- The central executive
What is the first slave system?
The phonological loop
What is the second slave system?
The visuospatial sketchpad
What is the third slave system?
The central executive
What is the main purpose of the phonological loop? (first slave system)
To hold words and rehearse any words that are currently being considered
What is the capacity of the phonological loop?
2 seconds worth of information
What is the coding of the phonological loop?
Acoustic (sounds)
What is the main purpose of the visuospatial sketchpad?
To hold static images and to manipulate them.
What is the capacity of the visuospatial sketchpad ?
3-4 objects
What is the coding of the visuospatial sketchpad?
Visual
What is the main purpose of the central executive?
Monitors incoming information and delegates to slave systems
Reasoning and decision making
What is the capacity of the central executive?
Limited
What is the coding of the central executive?
Modality free (not limited to sight or sound)
What is the main purpose of the episodic buffer?
To provide temporary storage information received by the central executive and maintain a sense of time frequency
