working memory model

• What does the Working Memory model describe?

  It describes the structure and function of short-term memory (STM).
• How does the Working Memory model function?

  It serves as a mental space for temporarily storing and manipulating information.
• Who proposed the Working Memory model?

  Baddeley and Hitch.
• What is the role of the central executive in the Working Memory model?

  It acts as a control center that monitors data and coordinates subsystems.
• Does the central executive store information?

  No, it does not store information.
• What is the capacity of the visuo-spatial sketch pad?

  It has a limited capacity of 3 or 4 items.
• What are the two subdivisions of the visuo-spatial sketch pad?

  Visuo cache and inner scribe.
• What does the visuo cache do?

  It stores visual data.
• What is the function of the inner scribe?

  It arranges objects in space.
• When was the episodic buffer added to the Working Memory model?

  In 2000.
• What is the purpose of the episodic buffer?

  It integrates material from other subsystems into a single memory.
• What does the phonological loop deal with?

  It deals with auditory information.
• What are the two subdivisions of the phonological loop?

  Phonological store and articulatory process.
• What does the phonological store do?

  It stores words that we hear.
• What is the function of the articulatory process?

  It allows for maintenance rehearsal.
• What are the strengths of the Working Memory model?

  • Clinical evidence from Shallice and Warrington (KF case study)
  • Validity supported by dual-task studies
  • Dual-task performance supports the visuo-spatial sketch pad
• What are the weaknesses of the Working Memory model?

  • Lack of clarity over the central executive
  • Central executive is the least understood part
  • Suggestions that the central executive may be subdivided
• What did Shallice and Warrington's study on KF suggest about the phonological loop?

  It suggested that the phonological loop was damaged while the visuo-spatial sketch pad was intact.
• What do dual-task studies indicate about the Working Memory model?

  They indicate that tasks sharing a subsystem are harder than tasks using separate subsystems.
• What did Baddeley et al. find regarding the visuo-spatial sketch pad?

  They found that participants struggle with two tasks using the same subsystem.
• Why is the central executive considered the most important part of the Working Memory model?

  Because it coordinates and controls the other subsystems.
• What is a criticism regarding the central executive in the Working Memory model?

  It lacks clarity and is the least understood component.
