The working memory model
The working memory model addresses one aspect of memory short-term or immediate. It is more concerned about the memory used when you are working on a complex task which requires you to store information as you go along.

Description of the working memory model
If you do two things at the same time and they are both visual tasks, you perform them worse than if you do them separately.
If you do 2 things at the same time and one is visual whereas the other involves sound then you are more likely to do well as the

Central executive
The CE decides whether to get information from the CE or the senses. The CE determines which resources to use. The ‘resources’ being the senses or long-term memory. The CE can’t attend to too many things at once, meaning it has a low capacity. It also can

Phonological loop
The phonological loop deals with auditory information and preserves the order of information. This is divided into 2 subsections:
The phonological store: holds the words you hear
An articulatory process which is used for words that are seen. These words a

Visuo-spatial Sketchpad
This type of memory holds information that is used when trying to remember a physical object. For example when trying to navigate a way around your house, or how something looks. Spatial information is the physical relationship between things.

Dual task performance
The main reason for developing the WMM was to account for dual task performance.
Hitch and Baddely supported the existence of the Central Executive in one study. Task 1 occupied the CE. Task 2 occupied both the articulatory loop and the Central Executive

Evidence from brain-damage patients
Studies of individuals with brain damage also support the WMM.
Shallice and Warrington (1970) studied a man called KF whose short-term forgetting of auditory information was much greater than that of visual stimuli. In addition his auditory problems were

Problems with using case studies
The process of brain damage is traumatic so that in itself could change someone's behaviour in terms of how they perform on certain tasks. Second, people may have difficulty performing certain tasks anyway. Lastly case studies are of unique individuals an
