Working memory model

• The working memory model, proposed by Atkinson and Shriffrin is a model of how our memory operates.
• Central executive: It's like the brain's CEO, managing tasks and attention. It decides what to focus on and helps switch between different tasks.
• Phonological loop is a store for verbal information.

  ->Phonological store: stores acoustic information

  ->Articulatory control system: allows for maintenance rehearsal
• Visuospatial sketchpad stores visual and spatial information.

  ->Inner scribe: spatial navigation

  ->Visual cache: stores visual information
• Episodic buffers binds and integrates information from all the components and passes it to long-term memory.
• The central executive controls attention an directs information to the two slave systems.
• Limitation) Baddely states that the central executive is the most important part of the working memory model, yet the least is known about it. This is important because it questions the reliability of the model.

  
  

  Strength)Dual task studies

  ->Performing a task using the same slave system = hinderance.

  ->Different slave systems = no hinderance.

  This suggests that the phonological loop and visuo-spatial sketchpad are sperate systems, supporting the idea that the w.m.m is made up of specialised stores.

  
  

  Strength)KF couldn't recall auditory info, but could recall visual info

  ->Proves STM is both auditory + visual store of info.
