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 articulatory control system do ?

  allows sub vocal repetition and maintenance rehearsal
• what does the phonological store 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 is a strength of the WMM ?

  dual task studies - perform better on tasks which use different components of WMM rather than same component
• what is a strength of WMM ?

  explains STM in both a temporary storage and active processing
• what is a strength of WMM ?

  PET scans show that different areas of brain are active while completing verbal and visual tasks
• what is a strength of WMM ?

  supported by case of patient KF
• what is a weakness of WMM ?

  only focuses on STM and not a comprehensive model of memory
• what is a weakness of WMM ?

  little research into the central executive
