Memory. What is Memory? Memory is a system that encodes, stores and retrieves information –Process by which information is taken in, converted to meaningful.

Memory  Short-Term Memory  activated memory that holds a few items briefly  look up a phone number, then quickly dial before the information is forgotten.

What causes Forgetting ? Biological or organic causes are the basis for a lot of forgetting. This Usually refers to damage to the brain brought about by:

Amnesia How biology affects one cognitive process - Memory

What is amnesia? How is it acquired?

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)

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

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

HM HM Memento Bike accident led to epilepsy

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

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

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

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

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

HM This suggests encoding and retrieval of long term memory are mediated by different systems. Which memory model does this support?

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.)
