working memory model

• what is the central executive ?

  controls attention and directs information to two slave systems ( phonological loop and visuo spatial sketchpad )
• what is the phonological loop ?

  processes auditory information
• what is does the inner voice do ?

  allows sub vocal repetition and maintenance rehearsal
• what does the inner ear do ?

  stores acoustic info for short period of time
• what does the visuo-spatial sketchpad do ?

  processes visual and spatial information
• what does the inner scribe do ?

  stored info abt spatial relationships between objects
• what does the visual cache do ?

  stores visual information
• what is the episodic buffer ?

  stores both visual and audio information

  can transfer information to LTM
• what are the strengths of the WMM ?

  • dual task studies - perform better on tasks which use different components of WMM rather than same component
  • explains STM in both a temporary storage and active processing
  • PET scans show that different areas of brain are active while completing verbal and visual tasks
  • Patient KF study
• what are the weaknesses of WMM ?

  • only focuses on STM and not a comprehensive model of memory
  • little research into central executive
