WMM

Cards (5)

  • Working Memory Model
    Developed by Baddeley and Hitch, focusses on short-term storage of info and says STM isn't a unitary store
  • Working Memory Model
    • Central Executive - monitors incoming data and allocates to 'slave systems'
    • Phonological Loop - processes audio info, split into Phonological store (words you hear) and Articulatory process (repeats sounds while needed)
    • Visuo-Spatial Sketchpad - processes visual and spatial info, split into Visual cache (visual data) and Inner scribe (arrangement of objects in visual field)
    • Episodic Buffer - integrates info and maintains time-sequencing (records events)
  • Strength of WMM
    KF had poor auditory STM but good visual STM, showing proof of separate stores
  • Strength of WMM
    Baddeley et al did research into dual task performance. Participants who did a visual and verbal task had good results. When both tasks were visual/verbal results declined, because the tasks are competing for space in a slave system.
  • Weakness of WMM
    Central executive is too vague, EVR had a cerebral tumour removed and did well on reasoning tasks but bad on decision-making, suggesting some of his CE worked and some didn’t
