Evaluation

• P - Strength , Supporting Evidence - Dual Task

  Baddeley and Hitch asked participants to do a task using different slave systems then the same slave systems in which the same slave system condition had performance significantly decline

  Supports WMM as central executive has limited capacity and so needs to divide attention making performance suffer

  D - Furthermore , brain scans light up different areas of the brain for different tasks making it apparent that the same slave system is being used for better cause and effect
• P - Limitation , Alternative Explanation - MSM

  MSM explains memory differently and both cannot be right

  Differing assumptions in linear and unitary stores

  Comparison between models , not explanation of MSM

  D - However , MSM flawed assumption of unitary stores

  KF had damaged auditory and not visual

  MSM cannot explain this whereas the WMM can
• P - Strength , Supporting Evidence - Phonological Loop

  Participants given mono and polysyllabic words to remember

  Before ( control ) ; mono has better recall due to word length effect

  After ( experimental ) ; suppress word length effect with repetition of ' the ' which made recall near equal


  D - However , supporting evidence was performed in a lab which makes a variety of problems for it such as lack of mundane realism
