– “I know that I exist, the question is, What is this ‘I’ that I know?”

Some Common Sense about the Self
• 1. Continuous over time, past, present and in the future
• 2. Singular
• 3. Responsible for controlling the mind and the body (‘will power’)
• 4. Determines your individuality

Cognitive Psychology is Soulless!
• Reason 1 concerns the brain– a. There may not be a single,
controlling ‘centre’ of the brain– b. Circuits can work independently
of one another
• Reason 2 concerns function– No Homunculi allowed!

Our Mental Library?
• New experiences and knowledge are filed away systematically
• Search and retrieval operations can take advantage of the library organisation to speed things up
• But how is all this managed? By a librarian?

How To Include the Self in a Cognitive Model
• The self is a biological / physical process, carried out by the brain
• Functions that support memory, attention, etc, should be independent (‘segregated’) from those involved in the self
• The neural basis for self-related functions may lie in the prefrontal cortex

Oliver Sach’s Patient Jimmie G.
• Korsakoff’s amnesic– A chronic alcoholic– Severe retrograde amnesia and dense anterograde
amnesia!– 49 years old, but considered himself to be 19 and living
in the late 1940s.
![Page 14: Lecture 5: Memory and the Self. Todays Lecture –Common sense ideas about the Self –Controversy within Cognitive Psychology over the self Its just an illusion?](https://reader034.fdocuments.us/reader034/viewer/2022051819/5515d83f550346d46f8b4970/html5/thumbnails/14.jpg)
McCarthy and Hodge’s Patient P.S.
• 67 year old stroke victim– Severe retrograde amnesia and dense anterograde amnesia!
• ‘A delusion more compelling than rational thought’– P.S. lived as if he was in the early 1940s.– His delusion was resistant to contrary evidence and
argument.

Memory’s Influence on Continuity
• Continuity depends on access to the full range of memories for past experiences
• Our ‘self-identity’ now may be constructed out of our most recent memories

Patient C.W.
• A middle aged victim of Herpes Simplex Encephalitis virus
– Severe retrograde amnesia and dense anterograde amnesia!
– Quote from C.W.’s wife: “He perceives the world as you or I do, but as soon as he’s perceived it and looked away, its gone for him. A moment to moment consciousness”
