Baddeley

• what was Baddeley's research on

  coding
• 4 groups in Baddeley's research

  group 1- acoustically similar words (sound similar)

  group 2- acoustically dissimilar

  group 3- semantically similar (similar meanings)

  group 4- semantically dissimilar
• Baddeley's findings

  when asked to recall words immediately( from STM)= acoustically similar words recalled worst

  asked to recall after interval of 20 minutes (from LTM)= semantically similar words recalled worst
• conclusions of Baddeley

  in STM information is coded acoustically

  in LTM information is coded semantically
• strengths of Baddeley(1966)

  high internal validity (controlled)

  high reliability ( strandarized procedure)

  identifies clear difference between two memory stores
• limitations of Baddeley

  artificial stimuli

  limited application

  lacks ecological validity
