• Baddeley and Hitch (1976):

  • Aim: To investigate if participants can use different parts of WMM at the same time
  • Procedure: Participants had to perform a dual task of repeating numbers and verbal true or false question
• Baddeley and Hitch (1976):

  • Results: As the number of digits increased, participants took slightly longer to reply, thus proving WMM exists
• KF study:

  • KF was a victim of brain damage from a motorbike accident
  • Although his ability to process verbal information was damaged (phonological), his ability to process visual information (visuospatial) was perfectly fine, showing they're separate stores
• HM study:

  • HM underwent brain surgery to remove his hippocampus, controlling his seizures
  • As a result, he could no longer make new memories, however, could recall childhood memories
  • This supports the linear model as it shows you cant unlock the LTM before it processes through the STM
• Clive Wearing study:

  • Clive got a disease that eradicated his hippocampus
  • This meant that he could still use STM but not "make memories".
  • This supports the linear model as it shows that memory has to go through each unitary store
