Working Memory Model

Made up of four components
1. Episodic buffer
  1. General store
    1. Deals with information that relates to both visual and auditory
  2. No storage capacity
  3. (2000)
2. Phonological loop
  1. Deals with auditory information
  2. Limited capacity
  3. Subdivided into...
    1. Phonological store (inner ear)
    2. Articulatory process (inner voice)
3. Central executive
  1. Limited capacity
  2. Determines how resources are allocated to tasks
4. Visuo-spatial sketchpad
  1. Logie (1995) suggested it can be divided into...
    1. Visual cache (store)
    2. Inner scribe
  2. Deals with visual and spatial information
Presented by Baddeley and Hitch (1974)
1. They felt that STM wasn't just one store
  1. When two tasks are performed at the same time, one auditory and one visual, they are done as well as they would have if done separately.
    1. When two tasks are performed at the same time, both either auditory or visual, they are done less well than if they had been done separately.
Evidence from brain-damaged patients
1. Supports WMM
  1. Study of KF
    1. Shallice and Warrington (1970)
    2. Shows that STM works independently of LTM
  2. Study of SC
  3. Study of LH
2. Limits WMM
  1. Brain injuries are traumatic and therefore can change behaviour
  2. No 'before and after' comparisons can be made
