Working Memory Model by
Baddeley and Hitch
Visuospacial Sketchpad
It holds the information we see and is used to manipulate the spatial information such as colours, shapes and object position
If you have to use spatial awareness such as moving through a building or doing a jigsaw, the visuospatial sketchpad helps.
It has 3 main possible parts: Visual, spatial and kinaesthetic. It is also believed to be located in the right hemisphere of the brain.
There are 2 parts, the visual cache which is where information about forms and colour are located and the inner scribe which deals with information about spatial and movement.
An example of how we use this in our long term memory would be remembering a route from school/work to our house again.
Central executive
Explains how tasks are allocated and how the system may be controlled.
A test requiring two tasks to be performed at one time to compare performance with one task is called a dual task paradigm.
The central executive gathers information from all the different stores and puts them together into one 'episode'
It coordinates and supervises the whole working memory to ensure the cognitive processes are running smoothly
It controls the flow and processing
Phonological Loop
Phonological Store
Deals with all the auditory information
It can also be called the primary acoustic store
It can hold a limited amount of verbal for a short period of time
Often called the inner voice or the inner ear
Information is assumed to last around 2 seconds before it decays
Articulatory Loop
retrieves memory traces by rehearsing them
this system can be used to explain the word length effect where shorter, monosyllabic words were recalled more successfully than the longer ones.
