LTM

• who researched into coding of LTM?


  baddeley
• outline the method baddeley used to research the coding of the LTM

  • gave participants 1 of 4 word lists
  • lists were acoustically similar, acoustically dissimilar, semantically similar or semantically dissimilar
  • participants recalled after 20 minutes
• what did baddeley find about the coding of the LTM?

  • did worse on semantically similar words
  • LTM is semantically encoded
• what's the capacity of the LTM?

• who researched the duration of the LTM?


  Bahrick et al
• outline the method bahrick et al used to investigate the duration of the LTM

  • participants aged between 17 and 74
  • identify schoolmates from photo-recognition test
• what were the results of bahrick et al's study into the duration of LTM?

  • participants who had left school within 15 years = 90% accuracy
  • left school earlier = 70% accurate
  • older participants were less good at free recall
• what's the duration of the LTM?


  unlimited
• evaluate research into duration

  Bahrick et al

  • high ecological validity due to task
  • lacked control over extraneous variables
• evaluate research into encoding

  Baddeley

  • oversimplified due to different types of long-term memory
  • practical application to education
• evaluate research into features of long-term memory

  • artificial tasks
  • Baddeley used word lists
  • lack ecological validity
