Working Model of Memory

• What does the Working Model of memory propose about short-term memory?

  It consists of multiple parts, not one unitary store
• What is the function of the Phonological Loop?

  It deals with acoustic/sound information
• What are the two sub-systems of the Phonological Loop?

  Articulatory Loop and Primary Acoustic Store
• What does the Articulatory Loop do?

  Voices information you are rehearsing
• What is the role of the Primary Acoustic Store?

  Holds onto the memory of sounds
• What does the Visuo-Spatial Sketch Pad deal with?

  Memory of visual and spatial images
• How is the Visuo-Spatial Sketch Pad structured?

  It has two components: one visual and one spatial
• What is the function of the Central Executive?

  Manages the two slave systems
• Does the Central Executive have storage capabilities?

  No, it does not handle memories
• What is meant by dual task abilities?

  You can perform two tasks using different stores
• What happens when two tasks use the same store?

  You will be unable to do both tasks
• What does the KF case study support?

  The Working Memory Model
• What was KF's impairment primarily related to?

  Verbal information
• What does Robbins' chess study demonstrate?

  Tasks using the same systems impair function
• How does the Working Memory Model compare to the Multi-Store Model?

  It provides more detail about STM processes
• How can the Working Memory Model help explain dementia symptoms?

  It shows decline in central executive ability
• What was added to the Working Memory Model in 2000?

  The episodic buffer
• What does the episodic buffer explain?

  How memory transfers from STM to LTM
• What conflicting evidence exists against the Working Memory Model?

  Parkin's brain scan found no CE activity
• What is a limitation of the Working Memory Model regarding LTM?

  It does not include long-term memory
• Why is the Central Executive considered less credible?

  Not much is known about its function
• What is a limitation of research methods used in studying the Working Memory Model?

  Most research is conducted in lab experiments
• What are the strengths of the Working Memory Model?

  • Supported by KF case study
  • Dual task studies confirm model's validity
  • More detailed than Multi-Store Model
  • Explains dementia-related memory issues
  • Includes episodic buffer for holistic view
• What are the weaknesses of the Working Memory Model?

  • Conflicting evidence regarding Central Executive
  • Lacks depth about long-term memory
  • Limited understanding of Central Executive's role
  • Lab-based research may lack real-world applicability
