The working memory model

AO1
1. outline
  1. functional
  2. focuses on STM
  3. separate components have different specialisations
    1. 4 components
      1. 1) CENTRAL EXECUTIVE
        3) VISUO-SPATIAL SCETCHPAD
        stores visual/spatial info
        4) EPISODIC BUFFER
        long-term memory
        added in 2000 limited capacity holds combined information
        2) PHONOLOGICAL LOOP
        phonological store (inner ear)
        holds verbal information limited capacity (two sec)
        articulatory process (inner voice)
        verbal rehearsal
        deals with auditory information
        - modality-free - controls attention - limited capacity
2. supporting evidence
  1. Baddeley (1975) short words are easier to recall
    1. there is no difference when you repeat something at the same time
  2. Hitch and Baddeley (1976) doing two tasks which involve the same component at the same time is difficult
  3. case studies (brain damaged people)
    1. KF
      1. forgetting auditory info faster than visual one
    2. SC
      1. couldn't learn word pairs, presented out loud
    3. LH
      1. spatial tasks better than visual
AO2
1. strengths
  1. explanatory power
    1. explains many observations
  2. supporting evidence
    1. a lot of supporting information
  3. recognises there are different kinds of STM
2. limitations
  1. description of Central Executive is too vague
    1. Damasio (1985) centre executive is not unitary
  2. research is mostly lab based
    1. low ecological validity
Baddeley and Hitch (1974)
