Working memory model Flashcards
what makes up the wmm
.Central executive
.Visuospatial sketchpad
.Episodic buffer
.Phonological loop
Who made the wmm
Baddeley and Hitch 1974
what is the central executive
.boss of the wmm (key component)
. controls attention and directs info to two slave systems
coding and capacity of central executive
Very limited capacity and is modalility free
What does modality free mean
all information
Who added episodic buffer and why
Baddeley(2000) added it because realised model needed more general store
What does the episodic buffer provide
Extra storage capacity (still limited)
Main role of episodic buffer
Intergrate info from all areas and send it to the LTM
(Is modality free)
What does phonelogical loop deal with
Auditory information and order of information
Divided into two sections
What are the two components of the phonological loop
- Articularoty control system
- Phonological store
What does the articulatory control system do
-Is inner voice
-allows for sub-vocal repetition known as maintanence rehearsal
What does the phonological store do
-Known as inner ear
-stores acoustic items for short period
What is capacity and coding of phonological loop
-Limited capacity (2 seconds)
-codes acoustically
What does the visuospatial sketch pad store
Visual and spatial info stored here
What does visual and spatial mean
Visual=what things look like
Spatial=relationship between things e.g location
What did logie (1995) do to visuospatial sketch pad
Subdivided into
Visuo-cache= Store
Inner scribe= Spatial relations
What does the central executive struggle with
Dual task performance as since it directs attention when tasks are systematic can’t direct attention
Dual task performance example
Ppts complete two tasks at same time
Condition1-complete two acoustic based tasks
Condition2- complete one acoustic based task and one visual based task.
Findings-when both tasks require phonological loop ability to perform tasks is impaired when compared to using two different store
Who was KF
1970, in motorcycle accident, gave Brain damage to left occipital lobe
STM damaged but LTM normal
Remembers better visually not auditory
What does KF say about memory
His phonological loop damaged but visuospatial sketch pad fine. Shows stores exist in different parts of the brain
