Presentation Transcript

  1. Amnesia How biology affects one cognitive process - Memory

  2. What is amnesia? • How is it acquired?

  3. Which would be worse? • Retrograde Amnesia (the failure to recall memories that have been stored before a trauma) • Or • Anterograde Amnesia (the failure to recall memories that have been stored after a trauma)

  4. Working with a partner, look online to find out what you can about Clive Wearing. • You have 3 minutes.

  5. Read page 78-79 of the course companion, then we’ll watch a clip of Clive Wearing and his wife.

  6. HM • HM • Memento • Bike accident led to epilepsy

  7. HM • Bilateral lesion to control seizures • Lost part of his hippocampus and amygdala

  8. HM • Unable to form new explicit long term memories • ANTEROGRADE AMNESIA • HM has provided vital information to the field of brain pathology

  9. HM • HM can complete tasks that require recall from short term and procedural memory, but not long term episodic memory. • What does this suggest?

  10. HM • Mirror writing • Before HM people didn't know memory could be localized to a specific part of the brain

  11. HM • HM can recall long term memories, but cannot create long term memories.

  12. HM • HM can recall long term memories, but cannot create long term memories. • This suggests encoding and retrieval of long term memory are mediated by different systems. • Which memory model does this support?

  13. Notes on CW and HM • Read the course companion p78-79 • Gross • Routledge • Make notes on separate coloured A4 sheets on Clive Wearing and HM. • (Be sure to include why these case studies are important to Psychology.)
