AO1 - The working memory model

• The working memory model is an explanation of the memory used when working on a task
• Central Executive monitors and coordinates all other mental functions in working memory
• Episodic buffer receives input from many sources, temporarily stores this information and then integrates it in order to construct a mental episode of what is being experienced
• The working memory model

  
• The Working Memory Model was created by the scientists Baddeley and Hitch in 1974.
• The Central executive direct attention to particular tasks, determining at any time how the brain resources are allocated to tasks.
• The phonological loop codes speech sound in working memory, typically involving maintenance rehearsal. This is why this campaign of working memory is referred to as a loop.
• The photological loop has a limited capacity. It also deals with auditory information and preserves the order of information.
• Baddeley further subdivided the phonological loop into:

  • The phonological store which holds the words you hear, like an inner ear
  • An articulatory process which is used for words that are heard or seen. These words are slightly repeated, like an inner voice. This is a form of maintenance rehearsal.
• The visual-spectail sketchpad codes visual information in terms of separate objects as well as the arrangements of these objects in one visual field.
• The visual spatial sketchpad is used when you have to plan a spatial task.
• Logie suggested that the visual spatial sketchpad can be divided into:

  • A visual cache which stores information about visual items e.g form and colour.
  • An inner scribe which stores the arrangement of objects in the visual field
