Working Memory Model

• Working memory model


  - An explanation of the memory used when working on a task. - Each store is qualitatively different.

  
• Central executive


  The part of working memory that is responsible for monitoring and directing attention and other mental resources.
• Phonological loop


  A component of working memory where we repeat verbal information to help us remember it
• Phonological store


  Component of the phonological loop of working memory that holds a limited amount of verbal and auditory information for a few seconds.

  
• Articulatory process


  Part of the phonological loop that repeats sounds or words to keep them in working memory until they are needed

  
• Visuo-spatial sketchpad


  Codes visual information in terms of separate objects as well as the arrangement of these objects in one's visual field.
• Visual cache


  Stores visual data

  
• Inner scribe


  Records the arrangement of objects in the visual field
• Episodic buffer


  A component of working memory where information in working memory interacts with information in long term memory (e.g.. relating information you are processing to a previous memory)
• Strengths of the working memory model

  Clinical evidence

  - KF could process visual information but had poor STM ability for verbal information.

  
  

  Dual task performance

  - Baddeley showed that participants had more difficulty doing two visual tasks rather than a visual and verbal task, because two visual tasks compete in the same slave system
• Limitations of the working memory model

  Nature of the central executive

  - Baddeley said the CE needs to be more clearly specified than just simply being 'attention'.
