  • Coordinates and controls the Phonological Loop, Visuospatial Sketchpad, and Episodic Buffer
  • Focuses attention and inhibits irrelevant information
  • Enables switching between tasks and mental sets
  • Facilitates the integration of information from different sources into coherent short-term memory
• What is the role of the episodic buffer?

  It connects long-term memory with working memory

• How does the episodic buffer differ from other components of the Working Memory Model?

  It acts as a backup storage system with greater capacity.
• What can amnesia patients still recall despite impaired long-term memory?

  Short stories
• What is the role of the Phonological Loop?

  The Phonological Loop is responsible for processing and storing verbal and acoustic information
• What components does the episodic buffer link together?

  • New information from the phonological loop

  It organizes and integrates information
• How does the episodic buffer function in the Working Memory Model?

  It integrates information from various memory components
• How does the episodic buffer compare to other components of working memory?

  It allows longer processing of complex information
