The Working Memory Model

• What is the working model of memory an improved version of?

  Short term memory store
• How does the working memory model differ from the short-term memory store?

  It explains processing of auditory and visual information
• What are the key components of the working memory model?

  • Central executive
  • Visuospatial sketchpad
  • Phonological loop
  • Episodic buffer
• What is the role of the central executive in the working memory model?

  It controls and directs attention to information
• What is the capacity limitation of the central executive?

  One type of information at a time
• What does the phonological loop process?

  Auditory information like sounds and words
• What are the two sections of the phonological loop?

  Phonological store and articulatory process
• What does the visuospatial sketchpad process?

  Visual and spatial information
• What are the two processors suggested by Logie for the visuospatial sketchpad?

  Visual cache and inner scribe
• What is the function of the episodic buffer?

  Integrates and stores information from various sources
• Why was the episodic buffer added to the working memory model?

  To explain integration of different types of information
• What does the AQA specification require for the working memory model?

  Features in the model coding capacity
• What is the coding type for the phonological loop?

  Acoustic
• What is the capacity of the phonological loop?

  What can be said in two seconds
• According to Cohen, what is the capacity of the central executive?

  Four items plus or minus one
• What evidence supports the working memory model?

  • Dual task performance study
  • Case study of KF
  • Brain scanning evidence for episodic buffer
  • Word length effect study
• What did Baddeley's dual task performance study demonstrate?

  Separation between the slave systems
• What was the case study of KF about?

  A man with selective short-term memory impairments
• What did the brain scanning evidence by Parapacaran show?

  Physical location of the episodic buffer
• What is the word length effect?

  People remember shorter words better
• What are criticisms of the working memory model?

  • Central executive is poorly defined
  • Reliance on laboratory studies
  • Lack of external validity
  • Inferences about memory processes may be incorrect
• Why is the central executive criticized?

  It is not fully operationalized in the model
• What is a limitation of laboratory studies in memory research?

  Poor external validity and mundane realism
• What does the term inference mean in cognitive psychology?

  Making educated guesses about memory processes
• What could undermine the working memory model's validity?

  Different processes may produce similar behaviors
• What should students focus on when preparing for the working memory model exam questions?

  • Key ideas and evaluations
  • Shape knowledge to answer questions
  • Practice drawing the model from memory
• What is the advice given for students feeling overwhelmed by the material?

  Focus on comfortable ideas and evaluations
• What is the purpose of the tutorial available for patrons?

  To provide a model answer for exam questions
• What should students do to stay updated with exam preparation videos?
