  • THE WORKING MODEL OF MEMORY- Braddeley &Hitch (1974)
      • places more emphasis on processes whereas the main point of the multi store model is the emphasis upon seperate memory stores.
      • A &S saw rehearsal in STM as a unitary process, whereas Braddley and hitch propse three rehersal loops
    • THE VISUO-SPATIAL SCRATCH PAD we use it when we hold images in our memories before we use them, also know as INNER EYE
    • THE PRIMARY ACOUSTIC STORE holds info in form of sounds, either directly or through the articulatory loop. INNER EAR
      • loop not included origonaly
        • EPISODIC BUFFER (2002) prepares material for transfer in to LTM
    • CENTERAL EXECUTIVE is the control centre. Works in any sensory modality. Directs incoming info to the correct loop for processing
      • Study of KF suppourts the idea that there are seperate memory stores, the fact that he had problems passing acoustic information to LTM whilst he was better at visual info suppourts the idea that the visuo spatial scratch pad store is seperate from thearticulatory loop, thus making this more plausable than MSM
      • BRADDELEY found that p's memory span for visually presented one syllable words was greater than for polysyllabic words. Suggests that the ariculatory loop is only able to hold limited syllable chunks.
      • High face validity - counting windows in house
      • Lab Experiments
      • Schizophrenia diagnostic processes, as defects in working memory can idicate the disorder
      • Functions of CE are vauge and hard to test. -unidentidied subsystems, how can we measure capacity
      • Structure not processes
