Working memory model Flashcards
What researchers thought STM to be more complex than the multi-store memory made out?
Baddeley and Hitch
What happens when an individual attempts to do 2 task that require the same components of memory?
This is called dual- task performance.
When using the same components for two different task this decreases performance as opposed to using 2 different components in two differing task.
What is the role of the central executive?
- Delegates info to slave systems e.g. Phonological loop and visuo-spatial sketchpad
- In charge of making decisions about which events should be ignored or which deserve attention
- Focuses on problem solving task and reasoning
What is the role of the phonological loop?
- Deals with auditory info
How are things encoded into the central executive?
- All forms of sensory coding
What are the two parts the phonological loop is made of?
Phonological store and articulatory process
What is the phonological store?
This is a component of the phonological loop that is known as the inner ear.
How long does the phonological store hold words you hear for?
1-2 seconds
What is the articulatory process?
This is a component of the phonological loop that is known as the inner voice and is used for words that have been heard or seen.
What is done with words that encode into the articulatory process?
They are silently repeated, as a form of maintenance rehearsal
How is information encoded into the phonological loop?
Acoustically
What is the capacity of the phonological loop?
2 seconds worth of info
What is the role of the visuo-spatial sketchpad?
Deals with visual and spatial information
When is the visuo-spatial sketchpad used?
When a person has to mentally plan a spatial task and form mental images
What are the two components of the visuo-spatial sketchpad?
The inner scribe
The visual cache
