WMM

Cards (28)

  • Is the WMM a broken down version of the STM or LTM?
    STM
  • The WMM is used for the temporary storage of information that we need to use or manipulate
  • What is the component of the WMM that supervises the other 3 ' slave systems ' ?
    Central executive
  • Does the CE have limited or unlimited capacity?
    Limited
  • Does the CE store information?
    No
  • Does the PL code acoustically or semantically?
    Acoustically
  • Does the PL or EB preserve the order into which information arrives?
    PL
  • The PL is divided into the:
    • Phonological store - stores words you hear
    • Articulatory process - allows maintenance rehearsal - capacity of 'loop' is 2 seconds worth of what you can say
  • VSS stands for the visuo-spatial sketchpad
  • The VSS stores visual and what type of information?
    Spatial
  • According to Baddeley, what is the limit of the VSS?
    3 to 4 objects
  • VSS is subdivided into:
    • Visual cache - stores visual data
    • Inner scribe - records arrangement of objects in the visual field
  • Was the EB added to the WMM in 2000 or 2006?
    2000
  • The EB can be seen as the what component of the CE?
    Storage
  • Does the EB have a limited or unlimited capacity?
    Limited
  • How many 'chunks' is the EB's capacity?
    4
  • Is the EB a temporary or permanent storage of information?
    Temporary
  • What is the term used to describe the recording of events happening?
    Time sequencing
  • Counting the number of windows in your house is used to illustrate the VSS
  • Does the case study of Clive Wearing or KF support the WMM?
    KF
  • STRENGTH OF WMM (1)
    P - Clinical Evidence - Shalice + Warrington case study of KF
    E - Brain Injury - Poor STM for auditory info but could process visual normally - Phonological loop = damaged but not visuo-spatial sketchpad
    L - Supports existence of separate visual + auditory memory stores
  • COUNTER TO STRENGTH(1)
    • P - Unclear if KF had any other cognitive impairments that affected performance
    • E - Injury = motorcycle accident - trauma may have affected instead
    • L - Challenge evidence with brain injuries affecting different systems
  • STRENGTH OF WMM(2)
    P - Studies of dual-task performance for separate existence of visual-spatial sketchpad
    E- Baddeley study (--)
    L - Separate subsystem that processes visual (VSS) + verbal (PL)
  • (--) BADDELEY DUAL TASK
    • Pps did dual task (visual + verbal)
    • Performance = similar to when they did it separately
    • When both task = visual x 2 OR verbal x 2 … performance = worse
    • Both visual tasks compete for same subsystem (VSS)
  • LIMITATION OF WMM(2)
    • P - No clarity over nature of the central executive (CE)
    • E - Baddeley - " Most important but least understood […] clearer than just ' attention ' " - Believed to have separate subsystems
    • L - CE = Poor component + challenges integrity of WMM
  • Does the EB or VSS maintain a sense of time sequencing?
    EB
  • What scans show that different areas are activated when doing verbal and visual tasks (PL + VSS = separate)?
    PET
  • PET scans indicate brain activation in the left hemisphere with visual tasks and the right hemisphere with spatial tasks (VC + IS = separate)
